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

Solar panels are powered by a free energy source — the sun — but to take advantage of this you will first need to pay to set up your panels.The installation cost is just one important factor you should bear in mind when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • The make and model of solar panels you’re planning on getting: More high-tech panels are more expensive, so that will influence your budget for your solar project.
  • 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: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your total installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will 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.
  • Electricity consumption: The average home in Hercules doesn’t use much energy, and therefore may not see as many savings on their power bills.

Solar is a fruitful investment for most homeowners. You can generate your own energy instead of paying for it from a utility company and take advantage of solar incentives, all while helping the environment.

Solar Incentives in Hercules

If you’re considering making the switch to solar power, a number of government incentives and solar rebates can immensely bring down the cost of the project and speed up the return on your investment.You can qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your solar panels. You can also possibly pair the ITC with other local rebates and benefits. Take a look at our article on solar incentives to see what incentives you can benefit from.

Environmental Impact of Switching to Solar in Hercules

Switching to solar energy can have a positive impact on the environment.But how much can using solar energy instead of traditional energy actually affect the environment? Using green energy for electricity rather than burning fossil fuels is an impactful way to reduce your carbon footprint if you're worried about Hercules' fair level of greenhouse gas emissions.Although solar panel production releases carbon dioxide emissions, the panels make up for it by significantly lowering the amount of CO2 you would have produced if you still used nonrenewable energy. In Hercules, you can reduce your carbon footprint by 50 pounds a year with solar panels. If you care about the environment, you’ll no doubt get that there are many good things about adopting solar energy other than just saving money on electricity. You can also help preserve the environment, which some would argue is priceless.
