Methodology: How We Ranked the Best Solar Companies in Irvine

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


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 Irvine

Solar panels run off a free energy source — the sun — but before you can take advantage of this you first need to pay to install your system.A few key factors that influence the cost of installing a solar panel system on your home and how much money you could save over time are:

  • Choice of solar panels: The kind of solar panels you get will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If you don’t need to maximize efficiency, you can go with a higher number of more affordable panels.
  • The amount of sunlight your city gets: Due to Irvine’s very high amount of average daily sunlight, you should be able to save a lot on your electricity bills.
  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 0 of the project cost. Your state may also have incentives and rebates that you can benefit from. Plus, you can save about $25,000 over 20 years on your utility bills, without incentives.
  • Electricity consumption: The average home in Irvine doesn’t use much energy, and consequently may not see as many savings on their power bills.

Although a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars over the lifespan of your panels. The question of how much, though, depends on a number of factors, such as the amount of daily direct sunlight available and your local electricity rates.

Solar Incentives in Irvine

There are several reasons why going solar is a great investment. One of them involves some government incentives that can help save you some money.No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will allow you to claim 0 of how much your solar project cost when you file taxes, reducing the amount of taxes you owe that year. Plus, there may be some local incentives you can benefit from too. For detailed information about local incentives, check out our article on solar incentives.

Environmental Impact of Switching to Solar in Irvine

Going solar can have a positive effect on the environment.Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Irvine, though. For homeowners who care about the environment, using solar power is a straightforward choice, especially since Irvine produces a fair amount of carbon dioxide emissions from its energy generation.Because solar panels don’t release greenhouse gas emissions into the atmosphere when generating electricity, they’re a good swap for traditional energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 50 pounds each year. Since solar energy is renewable and produces electricity without a carbon footprint, adding solar panels to your home is one easy step you can take to help preserve the environment.

EcoWatch's Irvine, CA Solar Company Rankings FAQs

What is the most reputable solar installation company in Irvine?

The best local solar company in Irvine is SunPower by Sun Solar-OC, with a rating of 3.00 stars.

What are a few of the advantages and disadvantages of switching to solar?

The biggest advantages of solar power are that it can lower or, for some, 100% erase your electricity bills, improve the value of your home and reduce your carbon footprint. The main disadvantages are that solar panels can be expensive to install, you may not see as many savings if you don’t use a lot of electricity and whether you can install solar panels depends on your roof configuration.

Is it worth installing solar panels on my house?

Solar panels can be a fruitful investment for a majority of homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your energy bills are already fairly low, solar panels might not be for you.

What is the best type of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels are less expensive but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and how much efficiency you're looking for.
