Methodology: How We Ranked the Best Solar Companies in Pittsburg

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


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 Pittsburg

For many people considering switching to solar, the decision of which solar company to hire comes down to prices.There are several factors you should consider when determining costs and your potential savings, including:

  • Your income and budget: This shapes what kind of solar panels you can afford.
  • Your location: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.
  • How much you spend on energy: The typical family in Pittsburg pays around $1,500 a year on energy use alone, so you could be looking at that much in savings.
  • Incentives: Those who install a solar energy system this year can save 0 of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $33,000 on your utility bills over 20 years without incentives.

There are several good benefits of solar despite the upfront cost of installation. It can help the planet and your finances. Additionally, it can boost the value of your home, leading to even more benefits if you want to sell your home later.

Environmental Impact of Switching to Solar in Pittsburg

There are a few primary reasons why many people are interested in solar energy: for the financial and environmental benefits.Something many might have in mind is how much can they really help preserve the environment by going solar anyway? If your family consumes a lot of energy, you can impact the environment even more by switching to solar energy.Even though solar panel production emits carbon dioxide, the panels make up for it by considerably reducing the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Pittsburg, you can reduce your carbon footprint by 50 pounds a year with solar panels. As you can see, going solar has so many other benefits beyond saving money. One of the primary ones is that you can help save the planet too.

EcoWatch's Pittsburg, CA Solar Company Rankings FAQs

What is the best solar panel installation company in Pittsburg?

In Pittsburg, SunPower is the most reputable local solar company. Our team of experts rates it 4.50 stars, so it's a great choice if you're planning to add solar panels to your house.

What is the negative environmental impact of making solar panels?

Solar panels can be bad for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Making solar panels uses a lot of energy as well. The energy payback period is about 1 to 4 years.

How long does it take to see a return on your investment after installing solar panels?

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.

When should I put up solar panels?

Although summer is the most popular time people install solar panels, the best time is actually winter. You can save money since there's less demand during the winter months, and it lets you be up and running with solar for the higher power bills you may get during the summer.
