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
When deciding on a solar company, most homeowners or business owners think about the costs above all. Some main factors that influence the cost of installing solar panels on your home and how much it could save you over time are:
- Your current power bills: Solar panels can substantially lower, or entirely eradicate, your utility bills. In Hercules, you can save an average of $88 a month.
- Incentives: Tax-paying citizens who install a solar system this year can save 30% of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $33,000 on your energy bills over 20 years without incentives.
- Your income and budget: This shapes what type of solar panels you can purchase.
- The amount of sunlight your area gets: Because of Hercules' very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
Due to solar panels now being cheaper than ever as well as local and federal solar incentives, they are a worthwhile investment for the majority of homeowners.

Local solar incentive programs depend on the location and, sometimes, utility company. Many states offer rebates for solar power, in addition to the federal solar tax credit. Take a look at our article on solar incentives to find out what incentives you can benefit from.
Environmental Impact of Switching to Solar in Hercules
A lot of people want to do their part to help save the environment, which for many is the main reason they're interested in installing solar panels. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Hercules, though. One thing to consider is your overall carbon footprint. For example, if you spend lots of time commuting to work and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions. Because solar panels don't release carbon dioxide emissions into the atmosphere when creating electricity, they're a good alternative to nonrenewable energy sources. In fact, you could reduce your carbon dioxide emissions by about 50 pounds each year. For homeowners who want to help the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.
