There can be solar tax credits and incentives available at the federal, state and local levels. The calculator above will show you the value of all incentives your home is eligible for.
2021 is shaping up to be a year of huge changes for residential solar energy programs in California. The state Public Utilities Commission is in the middle of making changes to net metering, the energy billing arrangement under which solar panel owners earn credit for their excess energy that they can later use to offset energy the draw from the grid at night. Those changes may result in much worse financial returns from solar for people who get panels installed after the new rules take effect.
On this page, we cover all of the solar and battery incentives, rebates and tax credits available for your California home solar installation. We also provide guidance on how low income solar power programs work.
We also encourage you to use the California solar incentives calculator above. It allows you to drill down and show only the solar incentives that are applicable where you live.
Learn what solar incentives are available to California homeowners
See what California solar incentives you qualify for based on your utility company and city
Find out how much these incentives and/or California solar tax credits will reduce your cost to go solar and add batteries
The federal solar investment tax credit will have the biggest impact on the cost you will face to go solar in California
This perk is commonly known as the ITC, short for “Investment Tax Credit”. If you install your photovoltaic system in 2020, the federal tax credit is 26% of the cost of your solar panel system. This is 26% off the entire cost of the system including equipment, labor and permitting.
Example: If your solar energy system costs $20,000, your federal solar tax credit would be $20,000 x 26% = $5,200.
The federal tax credit falls to 22% at the end of 2022.
With net metering in some states, you get full retail rate credit for the amount of electricity you send back into the grid with your solar panels.
With net metering, or “net energy metering” (NEM), you get near-full retail rate credit for the amount of electricity you send back into the grid with your solar panels. The reason why it’s near full retail rate credit instead of full retail rate credit for the electricity you send back to the grid is because California recently amended their NEM to NEM 2.0.
As part of that change, the energy you buy from your utility company comes with a small “non-bypassable charge” of 3 cents per kilowatt hour (kWh). Under NEM 2.0, you don’t get this same amount as credit when you send electricity back to the utility grid (Note, if you’re an LADWP customer, you still will get full retail NEM without this non-bypassable charge).
You’ll also need to sign up for a time-of-use billing plan (TOU), which has variable energy costs based on what time of day it is. Evening has the most demand, so your energy prices will be higher at this time.
While that may sound bad, you can do very well to offset TOU billing changes by installing a solar energy storage system. You can charge the battery during the middle of the day with your free solar electricity, and discharge in the evening, when purchasing from the grid would be more expensive.
With NEM, The amount of kilowatt hours (kWh) you send to your local utility and pull from it are “netted” monthly. If you use more than you send to the grid at the end of the year, you pay for the balance.
Net metering in California can be extremely valuable over the life of your solar system. When paired with TOU billing and the ability to send power to the grid during off-peak hours, your savings are enhanced even further.
Luckily, your solar installer is a net metering expert. They will help you design a solar system to maximize your savings.

California used to have a robust solar rebate program called the California Solar Initiative (CSI). The rebates available were fully used up by 2014, but the program succeeded in driving 3 terawatts of solar energy capacity to the grid.
Rebates live on for Californians with low income however. Check out the SASH and MASH programs outlined in the California solar incentives for low income households section below.
While some states still offer their own state tax credits for solar energy, California doesn’t anymore.
However, Golden State policymakers have enacted a property tax exemption for solar PV which is still going strong. This is a great perk, since solar panels will increase the value of your home by roughly 70% of system costs. So while the value of your home will go up, your property taxes won’t.
Example: If your solar system costs $20,000, your estimated property value increase of $14,000 will be tax exempt.
California is not only a national leader in solar, it is also a leader in solar battery storage, thanks in part to the Self Generation Incentive Program (SGIP).
If you install a battery storage system on your property that is serviced by PG&E, SCE, Southern California Gas, or SDG&E, you can take advantage of the SGIP incentive.
Battery storage systems that are smaller than 10 kW and are installed on a residential property are eligible for an incentive of $0.25 per watt hour of storage installed.
We outline how much you can save on battery storage when you use the SGIP incentive program in our breakdown of the SGIP rebate.
SGIP also has what is known as the “equity budget”. This budget has money set aside for solar batteries that are installed in low-income and disadvantaged areas.
The goal of the residential equity incentive is to catalyze more battery storage deployment in low-income areas.
Residential equity systems will receive a rebate of $0.85 per watt hour installed.
Low income homes that are located in either a Tier 3 or Tier 4 fire district, or that are in areas that have experienced two or more planned safety power shutoff (PSPS) events can qualify for an even higher incentive when they install battery storage on their home - this is known as the equity resilience incentive.
Projects that qualify for the equity resiliency incentive program will receive a rebate of $1.00 per watt hour of storage installed.
This covers almost the entire cost of a solar battery system. Check our blog on SGIP's equity resiliency program for more information.
Throughout the US, solar is adopted more in areas that have higher incomes even though low-income communities have the most to gain from the benefits of solar power.
Low income solar incentives have the ability to spur solar development in disadvantaged communities.
California has two types of low-income solar programs which are aimed for single-family homeowners and owners of multi-family properties:
The California SASH solar program provides huge solar money to single family homeowners. The program is administered by the non profit organization Grid Alternatives. They help provide green job training in low income areas to help people secure good-paying green energy jobs.
SASH program requirements
If you can qualify for the SASH program, you’ll get an upfront incentive of $3 per watt of solar installed.
So, if you want to install a 6 kilowatt system on your home, you’ll get an incentive of $18,000! That’s basically enough to pay for the entire cost of your solar system.
If you meet the following criteria, you could get this solar money:
To check if you live in one of the approved areas, explore this map.
The MASH program is designed for those fortunate enough to own a multi-family housing complex.
Those people can qualify for a large grant program to retrofit low-income multi-family housing developments with solar power.
Grants range from $1.10 to $1.80 per watt of solar installed. Exact amounts for different project types are listed on the California Public Utilities Commission website.
To qualify for MASH:
There are some additional qualifications listed in the MASH program handbook. The MASH program is currently fully subscribed. New applications will be placed on a waitlist.

I find AHS based on good review online. I start communicating with Meo in email. Meo is very knowledgeable, and he also give me a competitive quote compare with other installer. Meo do not oversell me, only sell the system what we need and Meo handle all the permit work and inspection completed. The installment was also run smooth. Meo and his team is so efficient. The installation job is done in very professional. Meo also stand by their product. I have one panel have under performance issue. Meo and David keep come to my home to diagnose issue , and help to process the warranty from the manufacturer to replace the panel They went above and beyond to support the customer. I highly recommend AHS.

My wife and I considered solar for years and spoke with many companies. We set the bar high when making big financial decisions and none of the companies was able to provide a level of knowledge and professionalism that we were comfortable with. When we revisited installing solar this past year we were introduced to NRG Clean Power and we finally found the right match. Our Project Coordinator, Leila Gorney, was there every step of the way. She kept the project moving, kept us informed, and always had an answer for my many, many questions. Their surveyors, electricians, installers, and everyone we came in contact with were professional and personable. Our HOA required a roof inspection after NRG made the roof penetrations for the mounting brackets. When the roofing company forwarded the report to me they wrote in an email: “I will have you know that our inspector was very pleased with the work of your solar installers! They did a great job.” I could go on but I think you get the point. NRG is a first-rate solar company. Our panels are producing as specified, we’ve achieved our energy goals, and we were 100% satisfied with the entire process. Based on our experience I would highly recommend NRG Clean Power.

SunLux had the best overall reviews and feedback from customers. We had engaged 6 other solar panel vendors and narrowed it down to SunLux based on our consultations. SunLux was one of the very few vendors that answered our questions truthfully. This was extremely important to us since we have a metal roof. The final factor was SunLux were reasonably priced. In addition the city inspections, solar panel installation and final activation with SoCal Edison went flawlessly. Our project manager, Berlyn, was the most detailed, communicative and honest 3rd party project manager I’ve ever dealt with. I’d honestly offer her a position at our company if I could. All of the SunLux folks at every stage in the process were conscientious and courteous.

Sol R Us checked all the boxes in what I was looking for in a Solar provider: local, certified, professional, great cost per kWh, longevity, trust, and service. Chose them after an extensive analysis of 20+ solar companies and am completely happy with the decision. They took care of all the operational parts and made my involvement minimal but transparent. System was installed when they said it would and done very professionally. The first contractor I've worked with who was showed up when they said, finished when they said, and cleaned up and did touch up. It is a beautiful system; well designed and installed. The whole team was a pleasure to work with.

As having solar system installed is a 20 years commitment, I spoke to 5 solar companies not just to compare the price but most importantly to see cross reference the information they provided.<br /><br />What I found out, sales reps mostly reply on the computer program generated quote. Interestingly, after analyzing the same PG&E electricity usage history, some quoted me 7.6kw and some quoted me 5.8kw system. That is a huge difference that I definitely would love to sort out why. Most sales rep will cite that is how their software calculates, some said that is based upon system needs to cover 100% PG&E usage. Only Ali from Highligh Solar clearly explained how PG&E Net Metering works, and made clear sense the system size he recommended.<br /><br />The most amazing about Ali is that any question I came up with, e.g. what is the back feed of my main panel, he can get me the right answer right away even after 6 weeks of his visit, with picture of my panel attached. <br /><br />Once the decision is made, Ali walked me through the proposal and contract review, and Dean, the owner, was also very accommodating to accept some revisions I requested.. <br /><br />Then Jesse helped with permits and project management, Sam helped with monitoring and PG&E application, plus the professional installation team who made the whole process as smooth as it gets.<br /><br />2 days after installation, I reported weird system reading from Solar Edge mobile app, Dean and Sam called Solar Edge and confirmed they need to replace the inverter, which then got scheduled and done in less than 2 days by next available technician.<br /><br />In the end, Dean also personally helped me understand Solar Edge monitor reading, and answer many solar production related questions!!!<br /><br />All in all, I highly recommend Highlight Solar for their well rounded professional team!!!!!! Their service deserved 6 stars!!!
