Methodology: How We Ranked the Best Solar Companies in San Joaquin
EcoWatch's solar experts analyzed each solar company in San Joaquin 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 Joaquin
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 Joaquin
For lots of homeowners, whether or not you should invest in solar panels depends the most on the cost. Some main factors that influence how much it will cost to install a solar panel system on your home and how much money you could save over time include:
- Incentives: Something that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that's equal to a percentage of the project cost. You can also save money on your power bills, which can generate an average of $34,000 of savings over 20 years.
- How much you spend on energy: The average household in San Joaquin shells out around $1,100 a year on electricity alone, so you could end up with that much in savings.
- Average daily sunlight: Since San Joaquin gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which influences how much you can save on your energy bills.
- Choice of solar panels: The kind of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If you don't need to maximize efficiency, you can opt for a higher number of more affordable panels.
So is buying solar panels worth it? Whether you want to reduce your energy bills, greenhouse gas emissions or both, solar panels are a good investment for many San Joaquin homeowners.

Solar Incentives in San Joaquin
There are many good reasons why going solar is a great investment. One of them consists of some government incentives you can take advantage of. On top of the federal solar investment tax credit, there are also some state- and city-level incentives, which in almost all cases, can be claimed in addition to the federal incentive, so you get to save even more. Take a look at our article on solar incentives to learn what incentives are available to you.
Environmental Impact of Switching to Solar in San Joaquin
Going solar can have a meaningful effect on the environment. A question many people might be thinking about is how much can they really help preserve the environment by switching to solar power anyway? In a city like San Joaquin where commute times can be pretty long, using solar power can help offset some of your carbon dioxide emissions from driving. Even though making solar panels emits carbon dioxide, the panels make up for it by greatly decreasing the amount of CO2 you would have been responsible for if you still used traditional energy. In San Joaquin, you can reduce your carbon footprint by 50 pounds a year with solar panels. If you want to do your part for the environment, you'll no doubt understand that there are many benefits of adopting solar power other than just saving money on electricity. You can also help preserve the environment, which some would argue is invaluable.
