Methodology: How We Ranked the Best Solar Companies in Tustin
EcoWatch's solar experts analyzed each solar company in Tustin 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 Tustin
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 Tustin
Solar panels are powered by a free energy source — the sun — but to take advantage of this you will need to pay to set up your panels.The installation cost is just one important factor you should keep in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:
- The type of solar panels you’re planning on getting: Some cost more, so that will influence your budget for your solar project.
- Average daily sunlight: Since Tustin gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which affects how much you can save on your energy bills.
- Incentives: One thing that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save money on your energy bills, which can result in an average of $25,000 of savings over 20 years.
- How much power your home consumes: Homes that consume lots of power each month may need more solar panels and, therefore, be more costly, but will also enjoy more savings over time.
Though a solar panel system costs a good chunk of money upfront, it can save you much more over the lifespan of your panels. The question of how much, though, depends on several factors, such as the kind of solar panels you get and your current power bills.

EcoWatch's Tustin, CA Solar Company Rankings FAQs
Which solar panel installer is the best in Tustin?
The best local solar company in Tustin is SunSolar U.S., with a rating of 5.00 stars.
Are solar panels actually bad for the environment?
Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Making solar panels uses a lot of energy as well. The energy payback period is about 1 to 4 years.
How long does it take to see a return on your investment after getting solar panels?
The average payback period for solar panel installation is about 9.3 years, but the exact period varies depending on the cost of electricity where you are, incentives and net metering programs.
How often do solar panels have to be replaced?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is how much energy they produce will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can continue to use them at a lower efficiency after that time.
