Methodology: How We Ranked the Best Solar Companies in Alamo

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


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 Alamo

We get that for most homeowners, the choice to invest in solar depends on installation costs. The cost of solar and the savings it generates vary depending on some important factors such as:

  • The amount of sunlight your city gets: Due to Alamo's very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
  • The type and model of solar panels you're planning on getting: Some have higher prices, so that will shape your budget for your solar project.
  • Your energy bills: This will determine your savings. In Alamo, the average homeowner can save about $1,100 a year on their electricity bills.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 30% of the cost of installing your solar panel system from your taxes. In addition, not including incentives, you can save about $33,000 over 20 years on your energy bills.

Though a solar panel system costs a sizable chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on several factors, such as the size of your house and your energy consumption.

Solar Incentives in Alamo

One of the great things about installing a solar panel system is earning government incentives. When you install solar panels on your home, you can claim the federal tax credit, or ITC. This credit currently lowers your tax bill by 30% of the cost of your solar panels. Plus, there may often be some local incentives that you can take advantage of to further save. In our article on solar incentives, you can read about the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Alamo

If you're thinking of adding solar panels to your home, one of the principal reasons why may be to lower your carbon footprint. You may be trying to figure out — how much do solar panels do for the environment anyway? In a city like Alamo where commute times can be very long, using solar power can help help reduce the carbon footprint of being on the road a lot. Though solar panel manufacturing releases carbon dioxide emissions, the panels make up for it by significantly reducing the amount of CO2 you would have been responsible for if you still used traditional energy. In Alamo, you can reduce your carbon footprint by 50 pounds a year with solar panels. The great things about solar power are plentiful — just like solar power is! That's why so many people have been happy with making the switch to solar.

EcoWatch's Alamo, CA Solar Company Rankings FAQs

Which solar panel installer is the best in Alamo?

In Alamo, APG Solar is the top local solar company. Our team of experts rates it 5.00 stars, so it's a great choice if you're looking to install solar panels on your roof.

What are the best and worst things about solar power?

The advantages of solar power are that it can lower or, for some, completely erase your electricity bills, improve the value of your home and reduce your carbon footprint. The disadvantages are that solar panels can be expensive to install, you may not save a lot if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

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

The average payback period for solar panel installation is about 5.5 years, but the exact period varies depending on local electricity costs, incentives and net metering programs.

How often do solar panels need to be replaced?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is the amount of energy they produce will have decreased by about 0.8% each year since installing them. You can opt to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
