Methodology: How We Ranked the Best Solar Companies in Commerce

EcoWatch's solar experts analyzed each solar company in Commerce 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 Commerce


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 Commerce

Solar panels are powered by a free energy source — the sun — but to take advantage of this you must first pay to install your system.The cost of solar and the savings it generates vary depending on a few important factors such as:

  • Choice of solar panels: The type of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
  • Your home's orientation toward the sun: This, along with the configuration of your roof, affects affect how much power your solar panels can make.
  • Typical energy usage: The more electricity 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.
  • Incentives: Tax-paying citizens who install a solar system this year can save 0 of their solar installation costs by taking advantage of the federal solar investment tax credit. You can also save about $25,000 on your energy bills over 20 years excluding incentives.

Due to the cost of solar panels being lower than before as well as various solar incentives, they are a sound investment for the majority of homeowners.

Solar Incentives in Commerce

One of the benefits of installing a solar panel system is receiving government incentives.Local solar incentives vary by location and, sometimes, utility company. Many states offer rebates for home solar power systems, in addition to the federal solar tax credit. Check out our article on solar incentives to learn what incentives you can take advantage of.

Environmental Impact of Switching to Solar in Commerce

One of the best reasons to adopt solar energy is to minimize your dependence on nonrenewable energy sources like burning fossil fuels, which are destructive for the environment.A question many people might be asking themselves is how much can they really help protect the environment by going solar anyway? No matter where you are, you can help the planet by switching to solar energy, but homes that consume lots of energy will have a bigger impact.Although solar panel production releases carbon dioxide emissions, the panels make up for it by significantly lowering the amount of CO2 you would have released if you still used nonrenewable energy. In Commerce, you can reduce your carbon footprint by 50 pounds a year with solar panels. If you care about the environment, you’ll likely understand that there are many good things about adopting solar energy other than just saving money on bills. You can also help protect the environment, which some would argue is invaluable.
