An extension of the solar tax credit was included in the COVID relief bill that just passed congress! A 4% reduction of the tax credit was planned to go into effect on January 1, so this extension is a very welcome surprise for homeowners to get affordable solar!

The new tax credit schedule for homeowners looks like this:

  • 2021: 26%
  • 2022: 26%
  • 2023: 22%
  • 2024: 0%

 

What is the solar tax credit?

The solar tax credit was established to support and expand access to solar energy for homeowners and businesses. Since then, it has spurred investment and research in renewable energy and as technology has continued to improve, the cost of going solar has continued to decline.

The tax benefit has also helped to stimulate job growth in the clean energy sector. In the past decade alone, American solar jobs have seen an increase of 167%, and that’s why I’m proud to be a part of why that number in California.

While the tax credit has been an excellent incentive to help more folks go solar and grow the industry, it was not intended to be permanent, lawmakers in Congress have been preparing for it to step down in 2021 and then fade out entirely in 2022. This extension is fantastic news for the thousands of homeowners to experience the benefits of low cost sustainable electricity — and it means you still have a chance to take advantage of bigger savings.

 

Who qualifies for the solar tax credit?

Your system will need to be installed by December 31, 2022 in order to qualify for the 26% credit. To be eligible, you must be currently paying federal income taxes. The solar tax credit is tied to your federal income tax burden — if you usually owe income taxes, it will reduce the amount you pay. If you usually receive a refund, it will increase the amount of your refund.  The tax credit can zero out what you pay for a year, but it is not refundable.

If you’re on a fixed income (i.e. veteran pension, social security), be sure to review your tax returns from last year to see how much tax you paid overall. If you do not have enough tax liability to claim the full credit in one year, you can roll over the remaining credits into the next year. Projects can take 2-3 months from contract to completion including all the engineering and permitting, so it’s best not to wait until December to make the call.

 

How do I get the solar tax credit?

You will claim the tax credit when you file your yearly federal tax return. When it’s time to file your taxes, you will need to complete IRS Form 5695 “Residential Energy Credit” to validate your eligibility for the tax credit and include this information when you file your regular income tax return (IRS Form 1040).

Please note: Since we’re solar folks and not tax preparers, we always suggest consulting with your tax advisor for guidance about your specific tax obligations.

Curious about your tax credit eligibility? We’d be happy to put you in touch with a tax professional that’s familiar with this section of tax law to help you determine your eligibility.

Are you looking into solar for a new house or building in Los Angeles? I love talking to homeowners about integrating solar into the construction of a new residential home. Since January 2020, it became California law to have solar installed on every new home construction. Here are a few things to make sure your new site is as solar-ready as possible.

Roof type: 

Solar panels are easily installed on asphalt shingles, concrete tile, or a metal seam roof. Certain flat rooftops such as torch down and TPO (foam) also qualify.  A solar roof-top array cannot be installed on slate, shake, or clay tiles. That’s because you’ll want your roof structure to be designed with plywood, not shake.

Roof obstructions: 

One of the most challenging things I encounter when installing roof-top panels is obstructions such as dormers, skylights, chimneys or bathroom vent pipes. Solar panels will need to be installed on the most southern exposed section of your roof, so it is ideal if you can either concentrate any obstructions on the north facing side, or try to keep them in a designated section of your other available roof space. This allows you to take advantage of the sunniest parts of your roof and maximize the area that can fit panels.

Planning for a ground-mounted array? Id love to take a look at the spot you’re considering. A ground-mount will need to be located in a fairly flat area – anything with more than a 10 degree slope will diminish the production of the system. Also if bedrock is found underground, that will disqualify the installation in that area.

Electric needs: 

If you can include a chase that runs from your attic to your electrical box, this will allow the installers to avoid running wiring on the outside of your home.

Building plans and construction:

If you have your design plans already, I can take a look at your blueprints and provide advice. I can also have our electricians connect with your electricians to ensure your home is solar-ready and whether you’ll want to incorporate smart home technology and battery storage.

Already have your location? 

If you happen to be integrating solar into the construction of a new residential home and have the address or coordinates for where you plan to build, I would be happy to assess the site for sun exposure and determine the optimal location for a solar array. Please also let me know if you plan to make changes to the site, such as removing trees to improve sun exposure.

How Solar Cells Work http://energywithrob.com/how-solar-cells-work/ Fri, 17 Jul 2020 22:41:07 +0000 http://energywithrob.com/?p=7282 Solar is a simple yet efficient technology that has improved over years.  Consistent innovation and research by manufactures have made solar not only more affordable and more powerful, but better looking too. Eventually solar is going to take over traditional methods of generating electricity.

Since 2007 the solar industry has been in consistent growth. Solar is becoming the new normal for energy generation in California.  Whether it’s improving the environment or setting up new regulations with utilities, the state is going to switch its power to renewables. How solar cells work isn’t as complicated as it may seem. From small residential rooftops to large acres of land solar PV energy is produced exactly the same way.   Even though solar manufacturers compete against each other, they all use the same formula and technology.

If you’re looking to go solar you may want to know what is actually going to be installed on your property. Here’s some basics on how solar cells work.

 

How Solar Cells Are Made

Inside those large solar panels are smaller square shaped PV cells. PV stands for photovoltaic which means “production of an electric current when exposed to light”. Solar panel manufacturers create the cells from a combination of various elements including silicon, quartz, boron, and copper. A chemical reaction occurs once these elements are exposed to sunlight which then converts the light into electricity. Because copper is super conductive, its electricity is then distributed as power.

Solar Panel Deconstructed

how solar cells work

The amount of photovoltaic cells on a single solar panel dictates the panel’s size. Despite such a wide variety of solar panels available, the most popular have 60 or 72 cells in each panel. Manufacturers design solar cells that vary in power. This is translated in Wattage. Wattage is the sum of how much electricity a single solar panel can generate. The more Watts a panel has , the more solar energy it will generate. Most panels on the market today average at 325 Watts.

 

How Solar Cells Produces Electricity

An installed solar system (array or collection of solar panels) will vary in its output of electricity.  The sun’s orientation in the sky travels from east to west. An ideal solar system will be pointed in the direction where it can absorb as much sunlight as possible.  Electric generation is seasonal. Productivity is determined by the time of the year and how high and how long the sun shines in the sky. Summer will always produce more power than winter.

 

Annual Solar Energy Output

 

Soiling is another aspect that determines a solar system’s output. Soiling happens when pollution, dust, dirt, collect on top of the panels over a long period of time. A rainy day or a rinse down from a gardening hose will clear up any debris and dirt.

 

Solar Cell Performance

Solar cell’s efficiency is going to determine how well it performs over the years and how much electricity it will produce from the sun. Every solar panel has a rating system for its performance. Today’s solar panels range between 18% to 22%. Obstacles such as clouds, trees, shade, weather, angle of the sun affect performance. The higher the efficiency – the more strength the panel has to collect solar energy.  However, the elements used to create solar cells do deteriorate over time.  Manufacturers know that the design of the panels are not meant to last forever. For that reason every solar panel has a degradation process. The good news is that the degradation is very slow. It takes 25 years for a solar cell to lose 20% of its production. So even after 25 years, a solar system is 80% efficient.  Manufacturer’s guarantee production of their solar products for 25 years.

 

Solar is a simple yet efficient technology that has improved over years.  Consistent innovation and research by manufacturers have made solar not only more affordable and more powerful, but better looking too. Eventually solar is going to take over traditional methods of generating electricity. So why wait? If you’ve been thinking about switching to solar power, schedule an appointment with me to know if you qualify.

It’s 2020 and installing solar PV is a no brainer. People consider going solar as a smart energy decision because it eliminates high utility rates. Nevertheless, the process to go solar can become challenging for the project teams. Getting to know how a solar project is managed will help resolve potential issues with the installation.

 

Getting to Know The Project Managers

Hiring a solar installer with an efficient and professional project management team is very important. Project managers oversee every solar installation. It’s their job to accurately and efficiently move the project pipeline from installation to activation. The installation phase begins once the engineering team has finalized a system design.

Solar Process

 

Before going solar, you’re going to want to be sure to trust the project management team.  Talk to your solar consultant and ask him/her about the project managers and how they work. The goal of the team is to facilitate. Consistent oversight, control, direction, and high attention to details are key qualities that matter. Ongoing communication with the solar customer will provide transparency with the project status. This whole process can take between 4-6 weeks.

 

Behind The Scenes of a Solar Project

The three primary aspects for solar project management are communication, coordination, and scheduling. The project management team collaborates with the engineers to submit construction plans to the city for permits. The plans roughly 20 pages include required documents such as datasheets, diagrams, and electrical schematics that outline the solar installation. Safety code by the Fire Department is also considered. It requires the solar array to have 3 feet clearance from the roof ridge and 1.5 feet clearance on the edges.

As long as the solar company knows what they’re doing, going solar is a simple and smooth process.   Certain conditions can delay the install or even disqualify it from receiving a valid permit. Some installers just don’t ask about certain conditions that can introduce a potential issue.  Issues that come up can delay the installation. Some examples:

  • Unpermitted structure or addition
  • Homeowners Association approvals/oversight
  • Electrical and roofing conditions
  • Attic space
  • Encumbrances
  • Title and Trusts

A home with an unpermitted garage or addition not built to code, won’t quality for solar.  City/county inspectors will fail the job if the home doesn’t meet building code.

Managing The Installation

Once the city/county has permits ready, the project management team takes over. They’re first job is to coordinate with suppliers or their warehouse and make inventory for all the solar equipment and components. Next they’ll assign a foreman to join the installation team on site.  They’ll review dates on the calendar that are open for the install. Selecting the right date will depend on the crew’s availability.

When the field crew is on site installing the system, the project manager will request constant updates. Field crews are accountable to ensure the job is done right and one time. It also helps resolve any issues discovered during installation. Once the crew completes the job, the project manager will contact the city/county to schedule an inspection. The inspector must verify the solar installation meets building code. City inspectors are tough and meticulous. They will determine whether the job gets a pass or a fail.  Corrections will be requested by the inspector if the job fails the inspection. The installation can’t move to the phase until the inspection is passed.

The utility has control to activate the solar system to produce power. Utilities have their own processes for system activation which may take some time.  Once they approve and grant the permission to operate, the solar installation is officially complete.

 

Getting to know how a solar project is managed will help the homeowner understand what to expect. Project managers oversee the project’s completion.  They’re in charge of communicating with internal teams including the engineers and field crews while also coordinating schedules with cities and utilities. A competent project management team controls the process and plans accordingly based on the scope of the project. They keep the project organized and under budget, taking care of issues at the design phase prior to install. They are responsible for the customer experience. When a homeowner has trust in the process, going solar becomes a breeze. Otherwise, the homeowner will end up managing the project themselves, which is not what they pay for when going solar.

Should I Own or Lease a Solar System? http://energywithrob.com/should-i-own-or-lease-a-solar-system/ Mon, 18 May 2020 05:00:16 +0000 http://energywithrob.com/?p=7243 Part of my job is to help homeowners navigate through the solar process. One the most popular questions I get asked is – “Should I own or lease a solar system?” Regardless of which option you go with, the key is to know how much you're going to save with solar vs. what you'll be paying the utility in the long-term. When going solar, you need the clarity to better understand which option is best for you.

Part of my job is to help homeowners navigate through the solar process. One the most popular questions I get asked is – “Should I own or lease a solar system?” Because different solar companies pitch their products in different ways, they can create misconceptions about both options which can confuse the homeowner.  When going solar, you need the clarity to better understand which option is best for you.

 

Owning Solar

Over the last 7 years, the majority of homeowners purchased their solar system. The main reason is because of tax incentives. The Federal Tax Credit (FTC) is a great way to save money when buying solar. Before 2020, people that purchased a system got a 30% tax credit from the government. The FTC is now phasing out. This year, people that buy solar are eligible to receive a 26% tax credit. Not everyone qualifies so it’s best to first consult with a tax advisor.  They’ll determine if you’ll be able to get a credit, which will be mailed to you. If you don’t qualify, that means you owe taxes and the credit will contribute to what you owe to the IRS.

Another reason why buying makes sense is the Return on Investment (ROI) you get. When you own solar, it will pay itself off between years 8-10 after purchase. Your ROI is based on the amount of money you save from not paying the utility company. Cool! The idea is to have solar power offset as much utility power as possible. Schedule an appointment to see how much utility power your home can offset with solar. When owning solar, you basically have no electric bill. The savings goes back into your wallet. By the 8th or 10th year, you’ll break even from the accumulated savings.  Every year afterward is completely free energy!

When deciding to own, you’ll either pay the full purchase price upfront or finance and make monthly payments with principal and interest. When financing, the lender will offer 5, 10, 12, 15, 20, 25 year payment terms. The interest rates (based on FICO) for the 5 year term begins at 2.99% while rates for 25 year term range between 7-10%. While some people are able to pay the solar outright, most prefer to pay monthly. Keep in mind that you’re still paying interest so at the end of the term you may have paid more than the original cost. The upside to financing is that there’s not pre-payment penalty. So if you’re able to pay it off sooner, go for it! When shopping for solar, just be sure to know who’s financing our loan. Some lenders may add a lien to your home.

Cash vs. Finance vs. PPA vs. Lease

 

Leasing Solar

Leasing solar has gained more attention in recent years. Today, leasing is the most popular option because it offers a $0 up front cost. When purchasing solar, either you’ll pay the full price or (if financed) you’ll pay the tax credit you received to the lender. Lenders are going to give you 18 months to pay them your tax credit in order to keep your monthly payments low. Otherwise, they’ll increase your monthly payment. When choosing a lease, you’ll only pay a super low monthly payment for the solar. The payment terms range between 20-25 years and are broken down into a monthly kilowatt (kWh) rate. In other words, the lease program is exactly like how you pay the utility company for their power. The main difference is that you’re paying at a much lower rate.

Leasing a solar is a great option if you’re not able to qualify for the tax credit or if you want the most minimal monthly payments possible for electricity. Another advantage why leasing is a great option is the warranties and protections you get. When you own solar, it’s your investment. So you’re going to want to be on top of the system’s performance. Solar companies that sell you a system usually don’t maintain the system’s performance. They just include the manufacturer’s warranties in their contract.

With a lease, the solar company has ownership. In the lease agreement, they’ve made promises on the solar system, so they have the burden to ensure it’s performing at the level that you agreed to lease it at. If for some reason, the system fails to produce the amount of energy that’s been promised by the solar company, then you’ll be reimbursed or credited for the difference you had to pay for utility power.

Most homeowners think that leasing solar means to be in debt but that’s not the case. There’s no debt or lien since it’s easily transferable. So if you happen to sell the home, it’s not required to pay off the full cost.  The new buyer will simply take over the payments just as they would with the utility company.

The Power Purchase Agreement

The Power Purchase Agreement (PPA) is another type of lease option. Rather than paying the same monthly payment over a 20-25 year period, with a PPA you just pay for the amount of power the system produces. Because solar generates electricity from the sun, a solar system’s production is seasonal. Meaning that generation is low during the winter and high during the summer. With the PPA you’ll be paying less power in the winter time and you’ll pay more for power during the summer time.

 

Both purchase and lease have their own benefits and features. If you’re unsure whether to lease or buy, consider the following factors:

  • How long are you going to live in the home?  If you’re planning to go solar and move out in 5-7 years, then go with the lease. By that time, more homes will have solar anyway because California State Law (Renewable Energy Act) requires it!
  • Maintenance Preference. If you like to be on top of your system’s performance, then purchasing is a better way to go. If you prefer another company to handle all and any issue that may arise from the system in the future, select the lease option.
  • Most cost saving option. If you’re looking to pay the cheapest price for solar right from the get-go, lease. If you’re patient and want to be free and clear with any energy costs by year 8-10, buy or finance the solar system.

When I discuss options with homeowners I ask them to think about how they intend to get a new car. Solar is similar, in a way. Like a car, it depreciates value, requires maintenance, comes with warranty, and has wear and tear over the years. Regardless of which option you go with, the key is to know how much you’re going to save with solar vs. what you’ll be paying the utility in the long-term. The long-term savings will be tremendous versus the cost you’d pay the utility company over the same amount of time. If you like to get a cost-analysis or breakdown of how much you can save with solar, schedule an appointment.

Let’s face it, we’re adapting to a different world. As the whole country is facing the Covid-19 outbreak, about every state has ordered Americans to quarantine themselves inside their homes. It’s obvious, the more time we spend at home, the more we’re going to consume. This including food, television, computers, laptops, ovens, heating/cooling, lighting, and electrical outlets to charge our devices.  Electric costs are already high in Los Angeles and for some of us not working, we need to be extra smart and consider how to reduce the electric bill during the Coronavirus stay at home order.

Unfortunately, many American have filed for unemployment, over six million to date. For homeowners in Los Angeles, they still have to pay their bills. For some, utility costs are the second highest monthly home expense. Here’s how you can make a difference and generating more savings that power.

 

Making Your Home Energy Efficient

If you haven’t received your latest electric bill yet, most likely when you do, you may find that you’re going to pay more than usual. There’s many ways to reduce energy use at home since we’re not going to stop consuming. We also need to maintain our sanity and comfort while in quarantine! Nevertheless we need to be smart with how we manage power.

 

 

 Your Thermostat

According to Department of Energy, 50% of your electric bill is from heating and cooling. Depending on how many people live in the household, different people are going to have various levels of comfort and that’s going to lead to a consistent adjustment of the thermostat.  Fidgeting with the thermostat is going to make your HVAC system work harder.  Keeping the thermostat at a consistent temperature between 68%-74% ideal.  If your home has ceiling fans, consider it as an alternative as we enter the summer months.  Also, regularly check the air filter and follow these steps to clean it.

 

 

Your Lights

Unless you love candles you’re going to be paying for power. Efficient lighting is key to any home. Do you know what type of light bulb is lighting your home? Homes typically have 4 types of light bulbs:

  • Compact Florescent Lights (CFL)
  • Incandescent
  • Halogen
  • LED

LEDs save the most power because they require a fraction of the amount of electricity to produce the same amount of light as standard incandescent bulbs. LEDs are about 75% more efficient. That means they don’t have to be replaced often.

If you’re able to check which bulb you have, then you can put a very simple strategy together in terms of how often and when you’ll want to keep those lights on.  For example, remember to turn of the lights when leaving a room. Despite some of us enjoy having a well lit home, energy costs are going to be higher than usual during the stay home order. If you know you can replace some bulbs with more efficient LEDs, consider purchasing online to avoid shopping and being out. Just be sure to sterilize the packaging before you bring it inside your home!

Outdoor lighting is usually left on for longer periods than indoor lights. If any areas around your home don’t need lighting, shut them off. Otherwise, if you haven’t done so already think about upgrading your outdoor lights with motion sensors or solar power.

 

 

 Your Devices

We all love our electronics. Computers, tablets, smartphones, televisions, electric trimmers and anything else with a rechargeable battery. Some of us that have families have a lot of these gadgets. Being home almost 24/7 means that’s we’re spending more time using them and that means more consumption.

In order to maintain your sanity while having access to technology and entertainment, think about what you can reduce in your home’s daily routine. For example, if you have both a desktop computer and/or a laptop or tablet, shutdown your desktop.

Another option is to bring the family together to watch content on a single device rather than everyone watching on different devices. Also, when your devices are not in use a good energy tip is to unplug them from the wall. Even thought electronic devices such as audio systems and televisions are off, if they’re still receiving an electrical circuit. If you have multiple devices in a single area, a power strip will make it easy to disconnect all of them together.

 

 

Your Appliances

With most appliances you save energy by using them less. Guess which appliance you’ll never use less? Your refrigerator! The best way to save money on your fridge is to use an efficiency model that’s Energy Star Certified. If you don’t know if you have and Energy Star fridge, check the back and look for a yellow label that read Energy Star. If you’ve purchased a new fridge with the last 15 years, then most likely you got one that’s Energy Star Certified.

 

Being energy smart to reduce the electric bill during the Coronavirus will help provide individual and families financial relief. Asking family members to be more responsible with how they use energy can go a long way in keeping your energy bills low. Utilities only have a certain amount of power they can distribute. When demand for power gradually increases, so does the utility rates. Every year, your utility company raises power rates by 5-10% per year. Back in 2015, electric rates averaged at 14 cents per kilowatt/hour. In 2020, utility customers are seeing an average rate between 22 -27 cents per kilowatt/hour. Contact me directly to learn more about how your utility charges you for electricity.

LG Battery Storage for Residential Homes http://energywithrob.com/lg-battery-storage-for-homes/ Wed, 18 Mar 2020 04:20:04 +0000 http://energywithrob.com/?p=6892 With stored energy, a home will be protected from any high peak rates. As long as there’s stored energy, battery will be the second in line power source helping to eliminate energy typically delivered by the utility. 

The post LG Battery Storage for Residential Homes appeared first on Energy WIth Rob.

Battery production delays are affecting demand for the Tesla Powerwall leading many homeowners to consider other options to store their energy. LG, one of the global leaders in consumer electronics began their R&D in solar technology in the mid 1980’s. Today, as a premium solar manufacture, their modules are among the highest in demand and efficiency. With over 172 patents in solar related areas and the trend in storage, LG officially announced their energy storage solution, LG Chem RESU 10H for residential homes.

How Battery Storage Works

With SGIP incentives available, there’s no better time to purchase an energy storage system.  Battery allows properties to collect energy from both a solar system and the utility which then can be stored and discharged at times when solar is no longer produce energy, such as during the night. With stored energy, a home will be protected from any high peak rates. As long as there’s stored energy, battery will be the second in line power source helping to eliminate energy typically delivered by the utility.  Charging an electric vehicle at night with stored energy from a battery is a great way to keep costs low and become more independent from the grid.

LG Chem and the Tesla Powerwall

Just like the Tesla Powerwall, LG Chem RESU is an AC energy storage system (with an internal DC converter). This means that you’ll be able to install the battery and integrate it with a pre-existing solar system. Both batteries include a 10 year manufacturer warranty and have a compact design that make it easy to install as either a floor-standing or wall-mounted system for indoor and outdoor settings.

LG Chem RESU 10H has a usable energy output of 9.3Kwh. The Tesla Powerwall offers 13.5kWh of output while both have 5kW max power.  To put this into context, average family home uses about 30 kilowatt hours of energy per day.  Average home solar system (6.6kW DC) will produce 17kwh per day with fully charged battery contributing to about a third of your energy needs.

How To Choose The Right Battery Storage System

If you’re shopping to purchase a battery storage system, consider the following factors:

  • Your home’s energy consumption
  • Your solar system’s production
  • The capacity of the battery storage unit

When it comes to purchasing battery storage you’ll want how much energy you use in addition to how much solar you produce. Your utility bill is a great tool to determine how much energy your home needs beyond what your solar system can generate and deliver in excess to the grid. By adding up the kWh you’ve received from the grid and subtracting that number with how much solar you produced during the same time-frame, you’ll know exactly how much additional energy you’ll want to offset with battery storage. While analyzing your bill, be sure to review how much energy you consume during the high or low peak hours of the day. This will give you an idea of the type of battery capacity you’ll need when solar is not producing. By tracking your solar system’s production on a monthly, weekly, and daily basis, you’ll have a better understanding of how a battery storage unit will contribute to your energy savings and use.  This way you’ll have a idea of which battery to purchase.

If you are unsure how to analyze your energy use or need help on how to monitor  your solar production, contact us and speak one of our energy facilitators to further assist you. It’s our job to help you meet your energy goals.

Summertime has its fun perks such as swimming, the beach, BBQs, and flip-flops, it also has its risks such as heat exhaustion, fires, and electric black outs. Not only is it important to be safe during the summer, but it’s also important to be energy efficient. Blackouts occur when there is a shutdown of electric supply (either intentionally or unintentionally) by the utility who supplies power to their customers. Too much demand of power transmitted by the utility company will eventually break the system. Despite utilities having capacity to power hundreds of thousands of homes and buildings, their grid can reach a point when demand becomes so high that it will lack available power, resulting in a blackout. Battery storage can protect you from blackouts in Los Angeles during a heatwave. The best way to be protected is to better understand how battery storage can prevent blackouts in California.

Whether you currently have a solar system or not, having a battery storage system can be your hero during an emergency or disaster event. During a heatwave, temperatures can exceed over 100 degrees forcing consumers to use more power than usual by reducing their A/C thermostats to pump cooler air. State sponsored programs like Flex Alert help bring awareness yet most people just can’t handle the heat.

 

Battery Storage Saves The Day

Battery storage (also known as battery backup) protects consumers from blackouts during heat waves and other disaster events. A battery storage unit will collect power, either from the grid or a solar system, then store it. The unit will only release that energy when it’s necessary. Its main function is to charge and discharge energy automatically – typically during high peak rates. When a blackout occurs the storage unit will release stored electricity to the property but to only those critical loads that are designated by the battery’s management system.

 

What is a Critical Load Center?

A critical load center is a separate electrical panel that’s installed with the battery. Critical loads include selected low consumption appliances such as lighting circuits, refrigerators, and a small room such as a den or office. The idea is to feed a limited amount of power supply to important areas of the property during a blackout. Because the battery storage unit has limited capacity, powering critical loads only allows the unit to be conservative by extending its energy discharge over a longer period of time.

 

Battery Storage and Solar – The Ultimate Energy Protection

Although it’s possible to have a battery storage unit without solar, it’s ideal to have solar along with battery storage. Why is this? During a blackout, the storage unit is going to take the utilities place as energy provider to the property. Depending on how long the blackout will be, the storage unit can only discharge energy that’s stored from the grid. If the blackout is only 30 minutes, the home or business will be protected. But if the blackout exceeds 5 hours, (depending on storage capacity) the battery will have released all it’s stored energy.

A solar system combined with battery storage allows the unit to store clean renewable energy from the solar panels as they generate electricity during the day, allowing the battery to continuously recharge itself. This results in a sustainable energy cycle where battery discharges and recharges continuously based on solar power production. The unit will then discharge the electricity to the critical loads. Whether a blackout or normal day, solar with battery storage is the most effective way to be energy independent. Keep in mind that it’s only during a blackout event that the storage will discharge to critical loads. Normal days, storage may discharge to more electric loads and appliances of the home or buildings. Lets face it, this is why battery storage can protect you from blackouts in Los Angeles!

 

Peace of Mind With Battery Backup

Let’s be honest, the city has an outdated power grid that is sensitive to high energy demand. resulting in blackouts. Blackouts are caused by different factors, some very dramatic and while other’s more common. Nevertheless, families and business have a smart opportunity to protect themselves during such events. Being prepared is the top priority and being sustainable brings peace of mind. In Los Angeles for example, a city that is growing in population and demand for energy, will fail to prosper as a larger community when their energy infrastructure isn’t capable to be a reliable source of power. It’s up to the homes and businesses to take responsibility and take advantage of the tools and technology that will allow their independence from grid reliability. Battery storage, with solar is the best option.

Why California Became a 100% Clean Energy State http://energywithrob.com/why-california-became-a-100-clean-energy-state/ Sat, 01 Feb 2020 10:06:19 +0000 http://energywithrob.com/?p=6883 As a leader in combating climate change, California deeply cares about the global mission to save future generations from living on a planet.

There’s a very clear reason why California became a 100% clean energy state – to reduce the impacts of global warming by reducing carbon emissions caused by humans. As a leader in combating climate change, California deeply cares about the global mission to save future generations from living on a planet that may be unbearable to live in. The state legislation passed the “100 Percent Clean Energy Act” (SB100) which requires all utilities to provide power from clean sources by 2045. The Senate Bill is designed to phase out energy sourced from fossil fuels over the next 27 years.

SB100 was originally written by California Senator Kevin De León and introduced to legislation in January 2017. De León, who came into office in October 2014, is California’s leading advocate for clean energy and climate policies. In 2015 he authored and passed Senate Bill 350 which requires all utilities in California to provide 50% renewable energy to their customers by 2030. With SB100, utilities must be 60% renewable by 2030.  Hence, you can credit the state’s politicians for the growth we have to the solar and wind energy industries.

 

Why Does California Care?

So why is California so committed to environmental policy? Simply because it has no choice. California’s environmental policies are based on global warming events the state has experienced first hand.  There’s no question that California is special yet so prone to conditions affected by global warming.  According the Office of Environmental Health Hazard Assessment, California has experienced serious weather events within recent years.  The last 4 years were the warmest on record with extremely hot days and nights becoming more frequent. Just this year, Los Angles experienced more than 4 consecutive record heatwaves within a 30 day period. The state also became drier, due to it’s longest drought on record between 2007-2016.  Massive brush fires have also been an unfortunate after effect of global warming. This year’s Mendocino and Carr fire’s and last years Thomas fire burned over 2.4 million acres releasing millions of tons of CO2 into the atmosphere.

Climate change has become a major concern for the global community within the last decade. Regardless of public and political disputes, the latest scientific research on the global warming has been indisputable.  Consensus among scientists who study climate over the past 100 years all agree that global warming is fueled by human activities that increase the amount of greenhouse gases (GHG) into the Earth’s atmosphere.  Al Gore’s documentary, An Inconvenient Truth, addressed the facts of climate change to educate and bring awareness to a broader audience. The fundamental message in the film explains the scientific research and warns us about the consequences we face if we continue polluting the planet with man made carbon emissions.

 

Time For Positive Change

Within the last 20 years, Earth has seen the most abnormal weather conditions on record.  Countries from around the world are experiencing extreme weather events from hurricanes, typhoons, and rain bombs to droughts, heatwaves, and fires.  You can say that California is now not just the “Golden State” but also the “Clean State”. The Global Warming Solutions Act of 2006 is one of many state policies passed to combat the rise of greenhouse gas (GHG) emissions.  The Paris Agreement, which California is committed to, requires all members (countries) to reduce their carbon emissions and limit the Earth’s temperature increase to 1.5 degree Celsius. Although the Trump Administration plans to renegotiate or exit from the Paris Agreement, it won’t stop California’s future in sustainability.

Based on California Public Utilities Commission (CPUC) goals, new homes that are built must meet Zero Net Energy (ZNE) standards. Zero Net Energy homes in Los Angeles reduce the carbon footprint resulting in energy efficiency and savings. ZNE homes produce at least as much energy as they consume, on average, over the course of a year – a zero cost toward energy consumption annually. Renewable energy such as solar is usually the power source of choice for NZE homes.

Energy Efficiency is the Foundation of ZNE

California’s official plan, the ZNE Residential 2020 Vision Framework, states that ZNE buildings should use two-thirds or less of the energy of the typical current home. When calculating ZNE, the initial energy efficiency rating of a home is 100. Any energy efficiency improvements bring that number down. Finally, a renewable energy-fueled power source (typically solar) is added to bring the home the rest of the way down to zero.

Energy efficiency measures to get a home “ZNE-ready” include:

  • Efficient envelope design strategies (e.g. insulation and double-paned windows)
  • Highly energy-efficient lighting technology
  • Day lighting (natural sunlight)
  • Energy-efficient HVAC (heating, ventilation, and air conditioning)
  • Energy controls, such as programmable thermostats and automation

Once these steps have been taken, it’s time to add the power source. Solar is most often used, and there are a few things homeowners should know when considering solar as part of ZNE.

How Zero Net Homes Affect Solar System Size & Cost

Newly-built Zero Net Energy homes in Los Angeles typically require one-third less power than similarly-sized conventional homes. So a house that might normally have required a 6kW system could get away with (at most) 4kW. Although that does not correlate directly to one-third less the price, a smaller system will cost less overall.

An increasing number of contractors also offer ZNE ready homes, which are energy efficient and wired for solar, but not yet connected to a system. Two years ago, the CPUC estimated the cost of ZNE at an additional $6-$8 per square foot of house. More recently, some contractors have begun offering the service at the same price as traditional construction, which speeds ROI on the reduced-size solar systems used by ZNE homes. Many homeowners still qualify for solar incentives in Los Angeles, too, so it has become less expensive to get solar for ZNE homes than it is for similar-sized homes that do not conform to ZNE standards.

How ZNE Retrofits Affect Solar Size

When an existing home gets a ZNE retrofit and then goes solar, how does the increased energy efficiency affect the home’s solar system power requirements? This ultimately depends on the extent of the retrofit. If a home’s energy efficiency rating is increased by 30%, the corresponding solar requirement will be 30% less than it was before the upgrade.

Solar System Monitoring is Part of ZNE

Many installers include power consumption monitoring systems when homeowners go solar. While this is a helpful feature for any home, ZNE consumption monitoring is especially useful. Since the goal of a ZNE solar system is to generate at least as much power as the house uses, you’ll want to confirm it’s performing as promised, even after you get your ZNE certification. Monitoring of both energy production and consumption will give you ongoing peace-of-mind that your rooftop solar system is doing its job.

If you’re considering buying a NZE-ready home, or retrofitting your existing home for NZE, let’s have that conversation. I have experience helping more homeowners go solar, and we’re here to answer your questions.
