Methodology: How We Ranked the Best Solar Companies in Oakley

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


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 Oakley

The cost of putting up solar panels has gone down greatly over the past several years, but it’s still a significant investment for most homeowners.There are several factors you should consider when trying to determine costs and your potential savings, including:

  • The make and model of solar panels you want: More efficient models have higher prices, so that will affect your budget for your solar project.
  • Where your home is: This influences how much sunlight your roof gets, which helps determine how many panels you need.
  • How much energy your household consumes: Homes that need a lot of energy each month may require more solar panels and, therefore, be more expensive, but will also save more on their energy bills over time.
  • 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 state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Excluding incentives, you can save an average of $33,000 over the first 20 years with your solar system, too.

So are solar panels worth it? Whether you’re trying to lower your electric bills, greenhouse gas emissions or both, solar panels are a worthwhile investment for many Oakley homeowners.

A lot of people want to do their part for the environment, which for many is the main reason they’re interested in installing a solar system.But you may be curious – how much exactly can you help by using solar power?

EcoWatch's Oakley, CA Solar Company Rankings FAQs

What is the most reputable solar panel installation company in Oakley?

The best local solar company in Oakley is SunPower by The Solar Quote, with a rating of 3.00 stars.

Are solar panels really bad for the environment?

Making solar panels uses chemicals and produces toxic waste that can be bad for the environment, which is the main downside of solar panels.

How long does it take for solar to pay for itself?

The average payback period for solar panel installation is about 7.0 years, but the exact period varies by local electricity costs, incentives and net metering programs.

How long do solar panels last?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is how much energy they produce will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can keep using them at a lower efficiency after that time.
