Methodology: How We Ranked the Best Solar Companies in San Luis Obispo

EcoWatch's solar experts analyzed each solar company in San Luis Obispo 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 Luis Obispo


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 Luis Obispo

For many people, the decision of which solar installer to go with comes down to how much it'll cost. There are quite a few factors you should consider when trying to figure out how much it will cost and how much you can save, including:

  • Incentives: Tax-paying citizens who buy and install a solar energy system this year can save 30% of their solar installation costs by taking advantage of the federal solar investment tax credit. You can also save about $35,000 on your electricity bills over 20 years excluding incentives.
  • How much energy costs for you: The typical family in San Luis Obispo spends around $1,100 a year on energy alone, so you could end up with that much in savings.
  • Your income and budget: This guides what kind of solar panels you can purchase.
  • The amount of sunlight your area gets: Because of San Luis Obispo's very high amount of average daily sunlight, you should be able to save a lot on your power bills.

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

Solar Incentives in San Luis Obispo

One of the benefits of installing a solar panel system is receiving incentives from the government. Regardless of what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will allow you to claim 30% of your project costs when you file taxes, reducing the amount of taxes you owe that year. Plus, there may be some state and city incentives that can save you some extra money too. Check out our article on solar incentives to learn what incentives you can benefit from.

Environmental Impact of Switching to Solar in San Luis Obispo

There are lots of reasons to switch to solar energy, like saving money on electricity bills and helping to reduce your carbon footprint. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in San Luis Obispo, though. If your household uses a lot of energy, you can help the environment even more by switching to solar energy. Because solar panels don't release CO2 emissions into the atmosphere when producing electricity, they're a good trade for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. As you can see, investing in solar has so many other rewards beyond saving money. One of the major ones is that you can help save the environment too.
