Methodology: How We Ranked the Best Solar Companies in El Monte
EcoWatch's solar experts analyzed each solar company in El Monte 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 El Monte
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 El Monte
For many readers, the decision of which solar company to choose depends on costs. There are quite a few factors you should consider when trying to figure out the overall cost and how much you can save, such as:
- Incentives: The federal solar investment tax credit, which can save you some money, allows you to deduct 30% of the cost of installing your solar panel system from your federal taxes. In addition, not including incentives, you can save about $25,000 over 20 years on your energy bills.
- The type of solar panels you're thinking of getting: Higher-efficiency panels have higher prices, so that will influence your budget for your solar project.
- Electricity consumption: The average household in El Monte doesn't use much energy, and consequently may not see as many savings on their power bills.
- Average daily sunlight: Since El Monte gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which impacts how much your electricity bills will be.
There are several good benefits of solar in spite of the initial cost of installation. It can help the planet and your bank account. Plus, it can boost the value of your home, resulting in even more benefits if you choose to sell your home later.

In our article on solar incentives, you can find out about the incentives you qualify for near you.
Environmental Impact of Switching to Solar in El Monte
One of the reasons so many people are considering going solar is to help reduce their environmental impact. A question many people might be asking themselves is how much can they really help save the environment by switching to solar power anyway? The average person has a sizable 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 figure out what to do. Using solar power is a simple thing you can do to help. In El Monte, the average resident can reduce their carbon footprint by 50 pounds a year once they go solar. The good things about solar power are infinite — just like solar power is! That's why so many El Monte residents have been happy with committing to solar.

EcoWatch's El Monte, CA Solar Company Rankings FAQs
Which solar company is the best in El Monte?
The highest-rated local solar company in El Monte is EE Systems Group Inc, with a rating of 3.00 stars.
Are solar panels really environmentally friendly?
Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.
Are solar panels worth it?
Solar panels can be a good investment for a majority of homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already pretty low, solar panels might not be for you.
What is the efficiency of solar panels?
Solar panel efficiency is the amount of solar energy that is converted into electricity. Most panels today have an efficiency rating between 15 and 20%. If your panels are more efficient, you'll need fewer of them for your home's energy needs.
