Methodology: How We Ranked the Best Solar Companies in San Carlos
EcoWatch's solar experts analyzed each solar company in San Carlos 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 San Carlos
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 San Carlos
Solar panels run off a free energy source — the sun — but to take advantage of this you first need to pay to set up your panels. The cost of solar and the savings it generates vary depending on a few important factors such as:
- Your location: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.
- System size and type: Some models are more pricy than others, so the one you want can raise or lower your initial investment. Plus, the more solar panels you need to get, the more it'll cost.
- Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 30% of the project cost. Your state may also have incentives and rebates that you can benefit from. Plus, you can save about $33,000 over 20 years on your utility bills, not including incentives.
- How much power your household needs: If your home uses a lot of energy, you'll reap more rewards from installing solar panels.
Even 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, including the amount of daily direct sunlight available and your local electricity rates.

Environmental Impact of Switching to Solar in San Carlos
If you're thinking of adding solar panels to your home, one of the principal reasons why may be to reduce your greenhouse gas emissions. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in San Carlos, though. A significant thing to think about is your overall carbon footprint. For example, if you have a long commute, your footprint may be greater, so adopting solar power for your house can help offset that. After you go solar, your carbon footprint can be lowered by about 50 pounds each year. If you care about the environment, you'll no doubt get that there are many advantages to adopting solar energy other than just saving money on electricity. You can also help preserve the environment, which some would argue is worth more.

EcoWatch's San Carlos, CA Solar Company Rankings FAQs
What is the top solar panel installer in San Carlos?
The highest-rated local solar company in San Carlos is Next Solar, Inc, with a rating of 3.00 stars.
What is the negative environmental impact of making solar panels?
Solar panels can be bad for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.
Is it worth installing solar panels on my house?
Solar panels require a large upfront investment that will cost you several thousands of dollars, but whether or not solar panels are worth it depends on a collection of factors like the cost of electricity near you and the amount of direct sunlight your roof gets.
When should I put up solar panels?
You can put up solar panels whenever it's convenient for you, but consider doing so in the winter when the demand is less. With fewer homeowners going solar, you could potentially see faster installation times and more savings.
