Methodology: How We Ranked the Best Solar Companies in Grass Valley
EcoWatch's solar experts analyzed each solar company in Grass Valley 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 Grass Valley
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 Grass Valley
The cost of installing a solar panel system has decreased significantly in the past few years, but it's still a large investment for most homeowners. The overall price and potential savings vary depending on a few important factors such as:
- How much sunlight your roof gets: If your roof doesn't see much direct sunlight, your solar panel system won't be able to produce as much energy, which will give you lower savings on power bills than a roof that gets a lot of sunlight.
- The type of solar panels you can afford: This is dependent on your income and budget.
- Your energy bills: This will dictate your savings. In Grass Valley, the average homeowner can save about $1,000 a year on their electricity bills.
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Aside from incentives, you can save an average of $31,000 over 20 years with your system, too.
Even though a solar panel system costs a decent chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on several factors, including the size of your solar panel system and your energy consumption.

Solar Incentives in Grass Valley
Although solar power is typically a big investment, it can save you a lot of money over the lifespan of your solar panels because of smaller utility bills and government incentives. In addition to the federal solar investment tax credit, there are also some local incentives, which in most cases, can be claimed in addition to the federal incentive, so you get to save even more. You can find out about the incentives available to you in our article on solar incentives
Environmental Impact of Switching to Solar in Grass Valley
If you're planning on adding solar panels to your home, one of the main reasons why may be to lower your carbon dioxide emissions. Something many people might be thinking about is how much can they really help the environment by going solar anyway? A significant thing to be mindful of is your overall carbon footprint. For example, if your commute is very long, your footprint may be greater, so adopting solar power for your house can help offset that. Even though solar panel production releases carbon dioxide emissions, the panels make up for it by considerably lowering the amount of CO2 you would have released if you still used nonrenewable energy. In Grass Valley, you can reduce your carbon footprint by 50 pounds a year with solar panels. For homeowners who want to help the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.
