Factors to Consider When Choosing a Solar Installation Company?

When considering going solar, keep these four factors in mind:

  1. Solar system size: Determine the right size of the solar panel system for your home to meet your energy needs.
  2. Additional system components: Consider other components like inverters, batteries, or solar roofs, and ensure your installer offers them.
  3. Warranty and guarantees: Look for companies with comprehensive 25-year warranties and workmanship guarantees for peace of mind.
  4. Solar financing and payment options: Compare payment plans, including leases, loans, and PPAs, to find what suits your budget.

How to look for the best California Solar Company?

When looking for a best solar company, consider one with fair pricing. In California, a 6 kW system typically costs around $15,060. To ensure reliability, read verified reviews on platforms like the BBB and Trustpilot. Considering California’s unique circumstances, here are some tailored tips when evaluating solar providers.

To find the best solar company in California, consider these key factors:

Energy storage options: 

If you are installing a home solar system in California, participating in net metering may not be the best option. This is because of the updated NEM 3.0 policy. This policy reduces payments for excess solar energy sent to the grid. Instead, consider storing excess energy in a battery bank for later use.

Look for a solar company experienced in battery systems and California’s installation requirements. NEM 3.0 makes solar battery systems a better investment than standalone solar panels.

Knowledge of incentive programs: 

Ensure your solar installer helps you claim all available incentives in your area. For instance, California offers rebates through the Self-Generation Incentive Program (SGIP) for adding energy storage systems. Seek a solar company that can assist in qualifying for this incentive, significantly reducing costs.

Experience with state codes and regulations: 

California’s building codes don’t just affect new buildings. They also apply to home improvement projects, such as installing solar panel systems. To expedite project approval and avoid permitting delays, choose a solar company familiar with local codes.

How Much Does Solar Installation Cost in California?

In California, the average cost per watt of solar panels is $2.51.

We asked 1,000 homeowners with solar panels how much they paid. Most said they spent between $15,000 and $20,000. However, for residential solar systems, total costs can exceed $25,000, inclusive of installation expenses.

Are Solar Panels Worth It in California?

California leads the nation in installed solar capacity. With abundant sunlight year-round and substantial solar incentives, solar panels are generally a smart investment in the state. Moreover, given California’s higher-than-average traditional energy costs, switching to renewable energy can result in significant savings.

However, solar may not be suitable for everyone. If shade covers your home’s roof, your solar system may not produce enough energy to fully offset your usage. Consult with a solar installer to determine if solar is the right choice for your situation.


Because of California’s expensive energy prices, there’s a bigger opportunity to save money on utility bills by using solar panels.

The federal government offers a 30% tax credit for solar energy. In California, there are also additional incentives available. These incentives can significantly lower the upfront cost of installing solar panels.

Solar panels can save the average household almost 17,000 pounds of carbon dioxide emissions every year.


California’s new net metering program, NEM 3.0, lowers the amount homeowners can make from selling extra solar energy.

Solar panels in California are cheaper than the national average, but they still have a high upfront cost.

Solar Incentives in California

Several California tax credits and incentives are available to help reduce the cost of your solar investment. Major utilities like SCE, SCG, SDG&E, and PG&E do not offer incentives for solar panels. However, smaller municipal utilities and electric cooperatives may provide them.

Look into these options if you are interested in installing solar panels. These smaller companies may have programs in place to help offset the cost of solar panel installation. Be sure to research and compare different incentives available from various providers.

Federal Solar Tax Credit

The federal tax credit is also known as the Investment Tax Credit (ITC). Available nationwide. The credit will be available until 2034.

When you install a home solar system, you can claim 30% of the total cost as a federal tax credit. For instance, by installing a 6 kW solar system in California for $15,060, you can qualify for a $4,518 tax credit. This would bring down your net system cost to $10,542.

Net Metering in California

California once had a good net metering policy. This policy paid residents almost the full value of extra solar energy they sent to the grid. However, with the introduction of NEM 3.0 in April 2023, net metering tariffs have significantly decreased.

Consequently, storing excess energy in batteries now makes more financial sense than selling it to a utility company. It’s important to note that NEM 3.0 does not apply to past solar owners. Those who qualified for the old rates can still keep them.

Other State Solar Initiatives

California offers two major incentive programs that can benefit solar panel and home battery owners:

  1. Self-Generation Incentive Program (SGIP): This program provides $150 per kilowatt-hour for battery systems in the service territories of SCE, SCG, SDG&E, and PG&E.
  2. Property tax exclusion: The state’s property tax exemption means you won’t have to pay additional property taxes due to installing a solar system. This exemption is available for systems installed before Jan. 1, 2025.

Additionally, California offers the DC-SASH and Equity Resilience Incentive programs exclusively for low-income households that meet specific requirements.

Solar Trends in California

California has long been at the forefront of adopting new technologies like solar photovoltaic (PV) systems and battery storage. Despite emerging competition from states like Texas and Florida, California remains the leader in solar capacity. Here are some key facts about California’s solar industry:

  • California boasts 41,675 megawatts (MW) of installed solar capacity, surpassing all other states. For comparison, Texas and Florida combined have 31,413 MW.
  • Over the next five years, California plans to add 21,002 MW of solar capacity, a 50% increase from current levels.
  • The state hosts the largest solar industry in the U.S., with over 2,400 solar companies contributing to a total investment of $92.8 billion.
  • Solar energy has generated 78,116 jobs in California.
  • In April 2023, California implemented NEM 3.0, a revised net metering policy that reduces tariffs for excess energy production. However, this presents an opportunity for increased savings through battery storage.

Take Advantage of California Specific Solar Incentives and Rebates

In California, there are several solar incentives available to residents to make installing solar photovoltaic (PV) systems more affordable and promote clean energy production. 

Choosing the Right Solar Equipment

When comparing different types of solar equipment, it’s essential to consider factors such as price, quality, and energy output. Solar panel systems are typically sized by watt, and the wattage output varies depending on the type of solar panels used.

In California, where sunlight is abundant, homeowners may opt for cheaper solar panels with lower wattage output, such as older 350W models, instead of cutting-edge 400W panels. Alternatively, they can choose high-efficiency PV panels that produce more power, allowing them to install fewer panels overall. This approach can lead to cost savings while still meeting energy needs.

For homeowners not living in areas prone to power outages, investing in a solar battery installation may not be necessary. However, in regions like California, where utility companies like PG&E frequently implement public safety power shut-offs during wildfire risks, having a solar battery can provide backup power and enhance energy resilience.

Explore Various Solar Companies in California

California boasts nearly 900 registered solar installers, offering you a wide array of choices for your solar needs. In this article, we’ve highlighted the top 10 solar installers in California. Feel free to reach out to each company for a quote and compare them to ensure you’re getting the best deal. If you receive a quote from one company but prefer another, inquire about price matching options.

Consider Cash Payment (If Feasible)

The payment method you select for your solar panel system can impact the overall installation cost. Opting to pay in cash, if feasible, is often advisable. While cash payments necessitate higher upfront costs, they result in the greatest savings over time since they don’t entail paying interest. Solar loans, on the other hand, offer more immediate affordability but result in slightly lower savings due to accrued interest over time.

Fortunately, California offers numerous financing programs to enhance the affordability and accessibility of solar for most homeowners. For instance, Property Assessed Clean Energy (PACE) programs are available to the majority of homeowners, reducing financing costs and upfront payments for solar systems.

It’s important to note that significant savings in California typically require coupling solar panels with batteries, which can substantially increase installation costs. Despite this, solar remains a worthwhile investment in California, albeit with a higher initial cost.

Will Solar Increase Your Home Value In California?

A study by Zillow revealed that homes with solar installations typically sell for about 4.1% more on average than homes without solar. Specifically, in Riverside, California, homes with solar energy systems sold for approximately $9,930 above market value.

Additionally, a study conducted by the Lawrence Berkeley National Laboratory found that for each kilowatt of solar installed, home resale value increased by nearly $6,000.

Frequently Asked Questions

Is it worth going solar in California?

Absolutely! Whether you reside in the state capital of Sacramento or further down in Southern California, going solar offers both potential energy savings and contributes to cleaner energy.

With abundant sun exposure and a plethora of tax incentives and rebates, California stands out as one of the prime states for installing residential solar power systems. Additionally, incorporating other solar technologies like backup batteries can ensure uninterrupted power supply during outages.
