Methodology: How We Ranked the Best Solar Companies in El Cajon
EcoWatch's solar experts analyzed each solar company in El Cajon 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 El Cajon
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 El Cajon
Solar panels are powered by a free energy source — the sun — but to take advantage of this you must first pay to set up your panels.The installation cost is just one important factor you should consider when looking into installing solar panels. How much it'll cost and how much you can save depend on things such as:
- How much sunlight your roof gets: If your rooftop doesn’t get a lot of direct sunlight, your solar panels won’t be able to generate as much energy, which will leave you with lower savings on power bills than a house with a roof that gets lots of sunlight.
- System size and type: Some models are more expensive than others, so the one you decide on can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
- Incentives: The federal solar investment tax credit, which everyone qualifies 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 $31,000 over 20 years on your energy bills.
- Electricity consumption: The average home in El Cajon doesn’t use much energy, and therefore may not see as many savings on their power bills.
So are solar panels worth it? Whether you’d like to lower your electricity costs, carbon dioxide emissions or both, solar panels are a worthwhile investment for many El Cajon homeowners.

Are solar panels worth it?
Solar panels call for a significant upfront investment that usually costs at least ten thousand dollars, but whether or not solar panels are worth it depends on a collection of factors like local electricity rates and the amount of direct sunlight your roof gets.
