Methodology: How We Ranked the Best Solar Companies in Berkeley
EcoWatch's solar experts analyzed each solar company in Berkeley based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Berkeley
Below are some the criteria we examined specifically for California solar companies
- Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
- Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
- Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
- Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
- Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
- Availability (10%): The bigger the service area, the higher the company will score.
- Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
- Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.
The Cost and Benefits of Solar in Berkeley
We know that for lots of homeowners, the choice to invest in solar depends on installation costs.The installation cost is just one important factor you should bear in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things such as:
- Incentives: The federal solar investment tax credit currently lets you lower your taxes by 0 of the project cost. Your state and city may also have various incentives that you can take advantage of. Additionally, you can save about $33,000 over 20 years on your utility bills, before factoring in incentives.
- Choice of solar panels: The type of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If you don’t need to maximize efficiency, you can go with a higher number of more affordable panels.
- How much power your household consumes: Households that use plenty of energy each month may call for more solar panels and, as a result, be more costly, but will also save more on their energy bills over time.
- The amount of sunlight your roof gets: Due to Berkeley’s very high amount of average daily sunlight, you should be able to save a lot on your energy bills.
So is installing solar panels worth it? Whether you’re trying to decrease your energy bills, greenhouse gas emissions or both, solar panels are a worthwhile investment for many Berkeley homeowners.

In Berkeley, SunPower is the top local solar company. Our team of experts rates it 4.50 stars, so it's a solid choice if you're looking to install solar panels on your house.
What is the negative environmental impact of solar panels?
Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing uses a lot of energy as well. The energy payback period is about 1 to 4 years.
How long does it take for solar to pay for itself?
Solar panels generally pay for themselves in about 6.9 years, but your solar payback period will vary based on your utility costs. The more your typical power bill, the quicker your solar panel system will pay for itself.
When should I install solar panels?
Despite summer being the most popular time people install solar panels, the optimal time is actually winter. You can save money since there's decreased demand during the winter months, and it lets you be up and running with solar for the more expensive power bills you may get during the summer.
