Methodology: How We Ranked the Best Solar Companies in Larkspur
EcoWatch's solar experts analyzed each solar company in Larkspur 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 Larkspur
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 Larkspur
Even though solar panels can save you a decent chunk of change on electricity bills over time, it's necessary to know the upfront costs. 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 such as:
- How much energy costs for you: The average household in Larkspur shells out around $1,100 a year on power alone, so you could end up with that much in savings.
- Incentives: Those who purchase and install a solar system this year can save 30% of their total solar spend by using the federal solar investment tax credit. You can also save about $32,000 on your utility bills over 20 years not including incentives.
- How much sunlight your roof gets: If your roof doesn't get a lot of direct sunlight, your solar system won't be able to generate as much energy, which will leave you with lower savings on electric bills than someone with a roof that gets lots of sunlight.
- The model of solar panels you can buy: This depends on how much you're willing to invest upfront.
There are lots of great benefits of solar in spite of the initial cost of installation. It can help the Earth and your bank account. In addition, it can raise the value of your home, resulting in even more benefits if you choose to sell your home later.

Environmental Impact of Switching to Solar in Larkspur
Swapping traditional energy for solar is a great way to do your part for a more sustainable future. But how much can switching to solar actually affect the environment? One thing that can drastically affect your carbon footprint is your commute time and how much you drive in general.

In Larkspur, the average household can lower their carbon footprint by 50 pounds a year after going solar. Since solar energy is renewable and generates electricity without a carbon footprint, adding solar panels to your home is one easy step you can take to help preserve the environment.

What is the negative environmental impact of making solar panels?

How long does it take for solar to pay for itself?

How much solar panel capacity do I need for my house?
