California Solar Incentives, Tax Credits, & Rebates

California offers several solar programs and incentives for homeowners. These programs help lower the cost of solar panels and add-on battery storage. California also has programs designed to make solar more affordable for low-income households. Beyond financial incentives, the state protects homeowners‘ right to own solar panels. 

Our team spent more than 80 hours researching applicable federal, state, and local incentives and laws that support residential solar owners. Below is an overview of California‘s solar incentives, programs, and laws. 

Disadvantaged Communities – Single-Family Solar Homes (DAC-SASH)

The California Solar Initiative (CSI) started the DAC-SASH program to make solar more affordable for low-income households. The program offers one-time, up-front incentives to help reduce solar panel costs. You must meet the following criteria to qualify for the program:

• You’re a current utility customer with Pacific Gas and Electric (PG&E), San Diego Gas and Electric (SDG&E), or Southern California Edison (SCE).
• You live in a qualifying low-income area, own your home, and live there full-time
• You live in affordable housing as outlined by Public Utilities Code 2852
• Your household income falls within or below 80% of your area’s median household income

You’ll begin by applying on the GRID Alternatives website. If approved, you could receive up to $3 per watt in solar rebates for a new system. If we apply those savings to an average 5 kilowatt-hour (kWh) system, you could save up to $15,000 on installation.

Our team reviewed the application process and learned that it requires several steps and significant paperwork. Some steps involved include verifying qualification, homeownership, income, and affordable housing status. Although you may feel discouraged by the lengthy process, it’s worth it to lower initial solar costs and benefit from long-term energy savings. 

Additional resources: You can begin your application at the GRID Alternatives website. 

Self-Generation Incentive Program (SGIP)

SGIP rewards homeowners for adding battery storage to their home solar system. California is prone to outages due to rolling blackouts or natural disasters, and solar batteries can help power your home in these emergencies. Created by the California Public Utilities Commission (CPUC), this program provides a one-time rebate of up to $200 per kWh of solar battery storage capacity. Adding high-capacity energy storage, such as the Tesla Powerwall, will extend your solar system’s energy efficiency, leading to more electricity bill savings. 

The SGIP is a tiered-block program, meaning its value gradually decreases as more customers sign up. If you’re considering applying, you should act fast. Eligibility requirements include the following:

• You must be a PG&E, SCE, SDG&E, or Southern California Gas Company (SoCalGas) customer
• Your installation must be completed by an approved SGIP installer
• Your home must be located within the eligibility area 

Most of the paperwork is handled by your battery installer, making this application process much easier than other incentive programs.  

Additional resources: Check the CPUC website for further details.

Equity Resiliency Program

Another SASH program, the Equity Resiliency Program (ERP) offers energy storage rebates. The program is geared toward low-income families who live in high-risk fire areas or have experienced two or more Public Safety Power Shutoffs (PSPS). A PSPS, or deenergization, occurs when utility companies shut down electrical power to reduce electrical infrastructure fire risk. This may happen during natural disasters, such as wildfires or flooding. 

SASH program participants can also qualify for ERP. Under this program, you could receive a rebate of $1,000 per kWh—almost enough to cover an average solar battery’s cost. 

Our team discovered that the ERP application was similar to the DAC-SASH programs. If approved for SASH, you won’t have to start the application from scratch, but you must supply additional paperwork detailing your installation address, professional installer, battery cost, and storage system capacity. Despite the tedious paperwork, this program nearly eliminates solar battery costs and helps you save even more on energy bills. 

Additional resources: Review the Equity Resiliency Program (ERP) for more details.

Active Solar Energy System Property Tax Exemption

This tax exemption applies to all California solar residents and removes the burden of added property tax. Most home improvement projects result in a property value boost. A move to clean energy has the same effect, with solar panels raising your home value. As home value increases, so do your property taxes. However, in California, you’ll benefit from higher property value without the extra taxes. 

There is no application process required. This is an automatic benefit for residential solar owners. 

Additional resources: Complete tax exemption details are on the California State Board of Equalization website.

Additional Local Rebates and Credits

You’ll find additional solar rebates and incentives through your city or municipality. These programs vary by area and could include one-time rebates or credits to reduce rooftop solar or energy storage costs. Certain utility companies offer extra savings for converting to solar energy. 

Rancho Mirage Energy Authority (RMEA) offers exclusive rebates to future and current solar customers. RMEA customers who install a new system or expand their current one receive up to $500 in a one-time solar rebate. You must be enrolled in RMEA for one year, own property, and be enrolled in the NEM program to qualify. 

Sacramento Municipal Utility District (SMUD) provides a voluntary tiered incentive program called My Energy Optimizer. Each tier offers additional savings and rebates based on your home upgrades. Here is an overview of the tiered payouts:

• The Starter level provides $50/kWh or up to $500
• At the Partner tier, you can earn $150/kWh or up to $1,500
• The Partner+ level increases your savings to $250/kWh or up to $2,500

Each tier has specific enrollment requirements. For example, the Partner+ level requires Tesla Powerwall ownership to qualify. 

We recommend checking the Database of State Incentives for Renewables and Efficiency (DSIRE) for a current list of local solar incentives. 

California Solar Rights and Easement Laws

The California Solar Rights Act (or CA Civil Code 714) protects residents from homeowners associations (HOAs) restricting their right to own and install solar panels. HOAs can enact “reasonable” restrictions on solar installations if they do not violate the following rules:

• Any restriction won’t exceed $1,000 in additional installation costs
• Restrictions won’t impact a solar system’s efficiency or performance by up to 10%
• HOAs must allow alternative systems with equivalent efficiency, cost savings, and overall cost

California Net-Metering

Net-metering (or net-energy metering) benefits homeowners with high-efficiency solar panels. High-performing systems generate more power than your home may need, resulting in unused excess energy. Net-energy metering allows you to sell this energy back to the power grid in exchange for energy credits from your electric company. Those credits apply to future bills, helping lower grid-tied power rates. 

In California, net-metering once served as one of the best ways to accumulate extra solar system savings. However, this policy changed for California recently. On April 15, 2024,  California shifted to the Net-Energy Metering 3.0 (NEM 3.0) plan. Under the new plan, homeowners receive energy credits at a rate 75% lower than previous payments. 

The difference is in the payback that utility companies use. Under the old NEM 2.0 program, homeowners received a 1:1 ratio for credits at the retail rate. The same rate you would pay for 1 kWh of power from the company was the same amount you earned back. Under the NEM 3.0 plan, you receive a lower wholesale rate, or the price it costs an electric company to produce 1 kWh.

Since NEM 3.0 offers less benefits, California‘s government officials encourage residents to invest in energy storage systems instead. This extra energy provides backup power during low-sun days, overnight, or blackouts. 

Thankfully, NEM 3.0 isn’t retroactive for current NEM 2.0 customers. The new policy only applies to new solar installations starting on or after April 15. Customers currently enrolled in NEM 2.0 can benefit from the higher credits for 20 years starting from their activation date. After that, they’ll move to the latest net-metering program. 

Although net-metering credits have decreased, you can still benefit from long-term savings. Each utility company rate varies, so we recommend checking with your local utility company and speaking to a rep about net-metering options. If installing energy storage is a better investment for you, we suggest using the Self-Generation Incentive to reduce battery costs.

Federal Tax Solar Credit

The federal government offers additional savings to make going solar more affordable. Thanks to the 2022 Inflation Reduction Act, the federal solar tax credit now provides a credit equal to 30% of solar panel system installation costs. The credit drops to 26% in 2024 and 22% in 2034. It will end after that unless renewed.

This credit is applied to your federal tax liability during tax time, helping to lower your owed taxes for that year. You can roll the remaining credit to the next year if it exceeds your owed federal tax amount. 

You must legally own your solar system to qualify. This is determined by your chosen financing option. If you pay in cash or take out a solar loan, you automatically qualify as the legal owner. With solar leases or power purchasing agreements (PPAs), ownership remains with your solar provider, so you won’t be able to use the federal tax credit.

California Solar Costs

Installing a solar power system in California costs around $16,380, according to EcoWatch.com. This averages out to $2.73 per watt—higher than the national average of $2.66. Despite these higher installation costs, California residents benefit from better long-term savings by moving away from fossil fuels. Federal and state solar incentives will also lower your solar panel costs. 

Let’s calculate for a 7 kWh solar system. Based on the per-watt rate, your system would cost $19,110 (7,000 x $2.73). We can immediately reduce those costs by 30% using the federal solar credit, lowering your investment to $13,377. That’s a savings of $5,700 before applying any other solar incentives. If you add a 13.5 kWh solar battery, you can use the SGIP incentive to save an additional $2,700. Additional city, municipality, and utility company credits lower costs even more. 

We recommend researching all available credits to make your up-front costs as low as possible. Solar experts we’ve spoken to recommend discussing available incentives with your solar company. Many companies are knowledgeable about local incentives and will assist with the applications.

How We Chose the Top Solar Companies

We researched and analyzed dozens of solar panels and solar installation companies. We then formulated a rating system based on each solar installer or manufacturer’s services and products. We weighed several significant factors, including the solar panels’ quality and type of solar panels offered, the customer support network, warranty lengths and limitations, and additional benefits such as mobile apps for monitoring and customer service. 

Speaking directly to representatives, we determined how each solar company personalizes its solar panel installation for each home. We also analyzed each company’s warranty options to ensure their product and performance guarantees match or exceed industry standards. 

We evaluated each provider based on their rating and history with the Better Business Bureau (BBB) to determine reputation. In addition, we analyzed the 100 most recent Google Reviews for each provider across various locations and branches.
