Methodology: How We Ranked the Best Solar Companies in Modesto

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


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 Modesto

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 panels. Some key factors that dictate the cost of installing solar panels on your home and how much it could save you over time are:

  • System size and type: Some models are more pricy than others, so the one you decide on can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
  • Incentives: Something that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that's equal to a percentage of the project cost. You can also save money on your utility bills, which can generate an average of $33,000 of savings over 20 years.
  • Your location: This affects how much sunlight your roof receives, which helps determine how many panels you need.
  • How much you spend on energy: The average household in Modesto shells out around $1,000 a year on power alone, so you could be looking at that much in savings.

Solar is a profitable investment for most homeowners. You can produce your own electricity instead of paying for it from the grid and benefit from solar incentives and rebates, all while helping protect the environment.

Solar Incentives in Modesto

One of the great things about installing a solar panel system is earning federal and potentially state incentives. When you install solar panels, you can take advatage of the federal tax credit, or ITC. This credit currently lowers your tax bill by 30% of the cost of your solar panels. Plus, there are often some state and city incentives that you can use to further cut back on the cost of solar of solar panels. In our article on solar incentives, you can see the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Modesto

There are a few primary reasons why homeowners are considering solar energy: for the good of their bank accounts and the planet. But you may be wondering — how much exactly can you help the environment by using solar power? An important thing to keep in mind is your overall carbon footprint. For example, if you have a long commute, your footprint may be greater, so switching to solar power for your house can help offset that. Although solar panel production emits carbon dioxide, the panels make up for it by greatly decreasing the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Modesto, you can reduce your carbon footprint by 50 pounds a year with solar panels. The good things about solar power are abundant — just like solar power is! That's why so many Modesto residents have been happy with making the switch to solar.
