Methodology: How We Ranked the Best Solar Companies in Costa Mesa
EcoWatch's solar experts analyzed each solar company in Costa Mesa 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 Costa Mesa
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 Costa Mesa
While solar panels can help save you a decent chunk of change on energy over time, it’s necessary to know the upfront costs.The cost of solar and the savings it generates vary depending on a few important factors such as:
- Your city: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.
- Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, allows you to deduct 0 of the cost of your solar system installation from your federal taxes. Plus, not including incentives, you can save about $25,000 over 20 years on your energy bills.
- The type of solar panels you can purchase: This is dependent on how much you’re willing to invest upfront.
- Your energy consumption: If your family uses a lot of energy, you'll benefit more from installing solar panels.
Due to solar panels decreasing in cost as well as several solar incentives, they are a worthwhile investment for the majority of homeowners.

EcoWatch's Costa Mesa, CA Solar Company Rankings FAQs
Which solar power company is the best in Costa Mesa?
In Costa Mesa, REPOWER OC is the top local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're looking to add solar panels to your roof.
What are the best and worst things about solar power?
A few of the biggest pros are that it reduces your electricity bills, it’s good for the environment, and it gives you a significant return on your investment (ROI). The most notable cons are that solar panels don’t produce electricity at night, they cost a lot upfront and solar panels aren’t always aesthetically pleasing.
How long does it take to see a return on your investment after buying solar panels?
Solar panels generally pay for themselves in about 9.3 years, but your solar payback period will depend on your utility costs. The higher your typical energy bill, the quicker your solar panel system will recoup your installation costs.
What are the different kinds of solar panels?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much efficiency you're looking for.
