Methodology: How We Ranked the Best Solar Companies in Lathrop

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


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 Lathrop

For the majority of homeowners, the decision to invest in a solar energy system comes down to the cost. The overall price and potential savings vary depending on a few important factors such as:

  • Average daily sunlight: Since Lathrop gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which influences how much your electricity bills will be.
  • How much energy costs for you: If your local utility rates are quite high, there's a better chance you'll have a higher return on your investment in a solar panel system. In Lathrop, you can save an average of $88 a month on your electricity bills.
  • System size and type: Some models are more pricy than others, so the one you choose can raise or lower your initial investment. Plus, the more solar panels you need, 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 take advantage of. Plus, you can save about $33,000 over 20 years on your utility bills, not including incentives.

So is buying solar panels worth it? Whether you'd like to decrease your electric bills, carbon emissions or both, solar panels are a great investment for many Lathrop homeowners.

Our article on solar incentives goes over more detailed information on the incentives you can take advantage of in Lathrop.

Environmental Impact of Switching to Solar in Lathrop

One of the most compelling reasons to switch to solar power is to cut your dependence on traditional energy sources like burning fossil fuels, which are destructive for the environment. Something many might have in mind is how much can they really help preserve the environment by going solar anyway? An important thing to consider is your overall carbon footprint. For example, if your commute is very long, your footprint may be bigger, so adopting solar energy for your home can help offset that. In fact, if you make the switch to solar power, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. If you care about the environment, you'll no doubt find that there are many good things about adopting solar energy other than just saving money on bills. You can also help protect the environment, which some would argue is priceless.
