Methodology: How We Ranked the Best Solar Companies in San Dimas
EcoWatch's solar experts analyzed each solar company in San Dimas 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 San Dimas
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 San Dimas
For a lot of homeowners, whether or not to invest in solar panels depends the most on the cost.The overall price and potential savings vary depending on a few important factors such as:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 0 of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $25,000 over the first 20 years with your system, too.
- How much sunlight your roof gets: If your roof doesn’t see much direct sunlight, your solar panels won’t be able to produce as much energy, which will leave you with lower savings on electricity bills than a roof that gets lots of sunlight.
- System size and type: Some models are more costly than others, so the one you want to get can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
- average energy usage: The more energy your home uses on average and the greater your current energy bills are, the more benefits you’ll see from making the switch to solar.
Even though a solar panel system costs a sizable chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on a number of factors, like the amount of daily direct sunlight available and your current power bills.
