Methodology: How We Ranked the Best Solar Companies in Gardena

EcoWatch's solar experts analyzed each solar company in Gardena 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 Gardena


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 Gardena

Solar panels run off a free energy source — the sun — but before you can take advantage of this you must first pay to install your system.The overall price and potential savings vary depending on some important factors such as:

  • Incentives: Something that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save on your utility bills, which can result in an average of $27,000 of savings over 20 years.
  • How much you spend on energy: If your local utility rates are high, there's a better chance you'll get a higher return on your investment in a solar system. In Gardena, you can save an average of $1,185 a month on your electricity bills.
  • Your income and budget: This affects what type of solar panels you can purchase.
  • Average daily sunlight: Since Gardena gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which affects how much you can save on your energy bills.

There are many good benefits of solar despite the upfront cost of installation. It can help the Earth and your wallet. In addition, it can increase the value of your home, resulting in even more benefits if you want to sell your home later.

Environmental Impact of Switching to Solar in Gardena

Switching to solar energy can have a meaningful impact on the environment.A question many homeowners might be wondering about is how much can they really help preserve the environment by switching to solar power anyway? A key thing to be mindful of is your overall carbon footprint. For example, if you have a long commute, your footprint may be bigger, so adopting solar power for your house can help offset that.Although solar panel manufacturing releases carbon dioxide emissions, the panels make up for it by greatly decreasing the amount of CO2 you would have released if you still used traditional energy.

Since solar energy is renewable and produces electricity without CO2 emissions, making the switch to solar power is one easy step you can take to help the environment.
