Methodology: How We Ranked the Best Solar Companies in Rossmoor
EcoWatch's solar experts analyzed each solar company in Rossmoor 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 Rossmoor
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 Rossmoor
Solar panels run off a free energy source — the sun — but to take advantage of this you will first need to pay to install your panels.The cost of solar and the savings it generates vary depending on some important factors such as:
- The type of solar panel system you have the money for: This is dependent on how much you’re willing to spend upfront.
- Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 0 of the project cost. Your state and city may also have various incentives that you can use. In addition, you can save about $25,000 over 20 years on your utility bills, before factoring in incentives.
- How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar system won’t be able to make as much energy, which will leave you with lower savings on electricity bills than a house with a roof that gets lots of sunlight.
- Your energy bills: This will dictate your savings. In Rossmoor, the average homeowner can save about $1,200 a year on their electricity bills.
Solar is a valuable investment for most homeowners. You can produce your own electricity instead of paying for it from a utility company and benefit from solar incentives and rebates, all while helping protect the planet.

The top local solar company in Rossmoor is SunPower by Sea Bright Solar, with a rating of 4.40 stars.
What are a few of the advantages and disadvantages of installing solar panels?
A few of the biggest pros are that it lets you spend less on your electricity bills, it’s good for the environment, and it can give you a good return on your investment (ROI).

Is it worth putting solar panels on my home?
Solar panels can be a great investment for many homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your energy bills are already fairly low, solar panels might not be for you.
When should I install solar panels?
Although summer is the most common time people install solar panels, the best time is actually winter. You can save money since there's less demand during the winter months, and it lets you be up and running with solar for the higher power bills you may get during the summer.
