Methodology: How We Ranked the Best Solar Companies in Monrovia

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


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 Monrovia

Solar panels run off a free energy source — the sun — but before you can take advantage of this you will need to pay to install your panels.The installation cost is just one important factor you should take into account when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • The amount of sunlight your roof gets: If your roof doesn’t see much direct sunlight, your solar panels won’t be able to produce as much energy, which will give you lower savings on energy bills than a house with a roof that gets plenty of sunlight.
  • Your income and budget: This affects what kind of solar panels you can buy.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your total installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $25,000 over 20 years with your solar panels, too.
  • How much energy your household consumes: Homes that consume plenty of electricity each month may call for more solar panels and, as a result, more upfront cost, but will also enjoy more savings over time.

Though a solar panel system costs a sizable 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 several factors, like the kind of solar panels you get and your energy consumption.

Solar Incentives in Monrovia

If you’re planning on switching to solar energy, a number of government incentives and solar rebates can immensely reduce the installation costs and speed up the return on your investment.Local solar incentives depend on the location and, sometimes, utility company. A lot of states offer rebates for solar power, in addition to the federal solar tax credit. You can learn about the incentives you can take advantage of in our article on solar incentives

Environmental Impact of Switching to Solar in Monrovia

There are lots of reasons to make the switch to solar power, like saving on utility bills and helping to lower your carbon footprint.You may be asking yourself – how much does going solar do for the planet anyway? Something that can dramatically affect your carbon footprint is how long your commute is and how much you drive generally. If you go solar and drive an electric car, you can significantly lower your carbon dioxide emissions by charging your car at home.Even though solar panel production releases carbon dioxide emissions, the panels make up for it by greatly reducing the amount of CO2 you would have been responsible for if you still used traditional energy. In Monrovia, you can reduce your carbon footprint by 50 pounds a year with solar panels. Since energy from the sun is abundant and makes electricity without a carbon footprint, making the switch to solar power is one easy step you can take to help the planet.

EcoWatch's Monrovia, CA Solar Company Rankings FAQs

Which solar panel installer is the best near me?

The best local solar company in Monrovia is SunPower by True Power Solar, with a rating of 3.00 stars.

What is the negative environmental impact of solar panel manufacturing?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Making solar panels needs a lot of energy as well. The energy payback period is about 1 to 4 years.

How long does it take to see a return on your investment after buying solar panels?

Solar panels generally pay for themselves in about 9.2 years, but your solar payback period will vary depending on your utility costs. The more your typical energy bill, the quicker your solar panel system will recoup your installation costs.

When is the best time of year to install solar panels?

Despite summer being the most common time people install solar panels, the perfect time is actually winter. You can save money since there's not as much demand during the winter months, and it lets you be up and running with solar for the more expensive power bills you may get during the summer.

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.
