Methodology: How We Ranked the Best Solar Companies in Union City
EcoWatch's solar experts analyzed each solar company in Union City 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 Union City
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 Union City
Solar panels run off a free energy source — the sun — but to take advantage of this you first need to pay to install your panels.There are a few factors you should take into consideration when determining how much it will cost and how much you can save, such as:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $33,000 over the first 20 years with your system, too.
- 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, the more it'll cost.
- Your home's orientation toward the sun: This, plus the configuration of your roof, affects affect how much power your solar panels can generate.
- How much electricity your household consumes: Homes that consume plenty of electricity each month may call for more solar panels and, consequently, more upfront cost, but will also benefit more over time.
Although a solar panel system costs a sizable chunk of money upfront, it can save you much more over the lifespan of your panels. The question of how much, though, depends on several factors, including the angle of your roof and incentives.

Environmental Impact of Switching to Solar in Union City
If you’re thinking of adding solar panels to your home, one of the principal reasons why may be to lower your carbon footprint.But how much can switching to solar actually help the environment? The average person has a substantial carbon footprint. Between their car, which releases over 10,000 pounds of carbon dioxide emissions each year, and electricity for their home, it can be overwhelming to think about what to do. Installing solar panels is a simple thing you can do to help.While making solar panels emits carbon dioxide, the panels make up for it by considerably lowering the amount of CO2 you would have produced if you still used nonrenewable energy. In Union City, you can reduce your carbon footprint by 50 pounds a year with solar panels. As you can see, investing in solar has so many other benefits outside of saving money. One of the primary ones is that you can help save the planet too.
