Methodology: How We Ranked the Best Solar Companies in Alpine

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


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 Alpine

For many readers, the decision of which solar company to choose comes down to total costs.The installation cost is just one important factor you should bear in mind when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:

  • The type of solar panels you have the money for: This hinges on how much you’re willing to invest upfront.
  • Average daily sunlight: Since Alpine gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which influences how much your electricity bills will be.
  • Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 0 of the project cost. Your state and city may also have various incentives that you can take advantage of. Plus, you can save about $31,000 over 20 years on your utility bills, without incentives.
  • How much power your household needs: If your home needs to use a lot of energy, you'll benefit more from installing solar panels.

There are lots of wonderful benefits of solar even with the initial cost of installation. It can help the planet and your finances. Additionally, it can boost the value of your home, resulting in even more benefits if you decide to sell your home later.

Environmental Impact of Switching to Solar in Alpine

One reason so many are considering going solar is to help reduce their environmental impact.But you may be wondering – how much exactly can you help the planet by using solar power?
