Methodology: How We Ranked the Best Solar Companies in Hercules

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


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 Hercules

The cost of putting up solar panels has decreased significantly in the past several years, but it’s still a substantial investment for most homeowners.The installation cost is just one important factor you should bear in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:

  • Your income and budget: This determines what kind of solar panels you can afford.
  • Average daily sunlight: Since Hercules gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which influences how much your electricity bills will be.
  • Incentives: Something that can save you money on your solar project 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 on your power bills, which can give you an average of $33,000 of savings over 20 years.
  • Electricity consumption: The average home in Hercules doesn’t use much energy, and therefore may not see as many savings on their power bills.

Though a solar panel system costs a good chunk of money upfront, it can save you a considerable amount in the long term. The question of how much, though, depends on several factors, such as the amount of daily direct sunlight available and your energy consumption.

Solar Incentives in Hercules

Although a solar power system is typically a large investment, it can save you a significant amount of money over several years because of reduced power bills and government incentives.In addition to the federal tax credit incentive, there are also some state- and city-level benefits, which in the majority of cases, stack with the federal incentive, so you can save even more. For detailed information about incentives for homeowners in Hercules, see our article on solar incentives.

Environmental Impact of Switching to Solar in Hercules

Going solar can have a positive effect on the environment.But you may be curious – how much exactly can you help the planet by making the switch to solar? Adopting solar power is a great choice for the environment, because the biggest source of greenhouse gas emissions in the U.S. is from burning fossil fuels for electricity, heat, and transportation – all of which can be powered by solar instead.Because solar panels don’t release carbon dioxide emissions into the atmosphere when producing electricity, they’re a good swap for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. The great things about solar power are infinite — just like solar power is! That's why so many Hercules residents have been happy with making the switch to solar.
