Methodology: How We Ranked the Best Solar Companies in Moraga

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


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 Moraga

Solar panels run off a free energy source — the sun — but before you can take advantage of this you must first pay to set up your system.Some important things that impact the cost and possible savings include:

  • How much you spend on energy: If your local electricity rates are quite high, there's a better chance you'll get a higher return on your investment in a solar system. In Moraga, you can save an average of $1,538 a month on your electricity bills.
  • Average daily sunlight: Since Moraga gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which influences how much your solar panels can save you on your electricity bills.
  • System size and type: Some models are more costly than others, so the one you want to get can raise or lower your initial investment. Plus, the more solar panels you need, the more it'll cost.
  • Incentives: The federal solar investment tax credit, which can save you some money, lets you deduct 0 of the cost of installing your solar panel system from your taxes. Additionally, not including incentives, you can save about $33,000 over 20 years on your energy bills.

Solar is a profitable investment for most homeowners. You can make your own electricity instead of paying for it from a utility company and benefit from solar incentives, all while helping protect the planet.

Environmental Impact of Switching to Solar in Moraga

One of the best reasons to switch to solar energy is to reduce your reliance on traditional energy sources like burning fossil fuels, which are hazardous for the environment.A question many might be asking themselves is how much can they really help save the environment by going solar anyway? The amount of energy you use is a significant factor to consider. The more energy your home uses, the larger your impact when you make the switch to solar power.Although making solar panels emits carbon dioxide, the panels make up for it by considerably reducing the amount of CO2 you would have released if you still used traditional energy. In Moraga, you can reduce your carbon footprint by 50 pounds a year with solar panels. As you can see, using solar power has so many other rewards apart from saving money. One of the major ones is that you can help save the Earth too.
