Methodology: How We Ranked the Best Solar Companies in La Puente

EcoWatch's solar experts analyzed each solar company in La Puente 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 La Puente


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 La Puente

For many homeowners, whether or not to invest in solar panels depends the most on the cost.Some important factors that influence how much it will cost to install a solar panel system on your home and how much it could save you over time are:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 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. Not including incentives, you can save an average of $25,000 over the first 20 years with your solar system, too.
  • Choice of solar panels: The type of solar panels you get will affect your total cost. High-efficiency monocrystalline panels are more expensive 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.
  • Your current electric bills: Solar panels can dramatically lower, or totally get rid of, your utility bills. In La Puente, you can save an average of $1,185 a month.
  • Average daily sunlight: Since La Puente gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which influences how much your electricity bills will be.

There are lots of great benefits of solar even with the upfront cost of installation. It can help the Earth and your wallet. Additionally, it can raise the value of your home, resulting in even more benefits if you choose to sell your home later.

Solar Incentives in La Puente

There are many reasons why adopting solar power is beneficial. One of them involves some government incentives you can take advantage of.You can qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your solar panels. You can also potentially stack the ITC with other local rebates and benefits. Our article on solar incentives has more detailed information on the incentives you can find in La Puente.

Environmental Impact of Switching to Solar in La Puente

There are tons of reasons to make the switch to solar energy, like saving some money on utility bills and helping to lower your carbon footprint.A question many homeowners might have in mind is how much can they really help protect the environment by switching to solar power anyway? Adopting solar power is a sustainable choice for the environment, because the greatest source of greenhouse gas emissions in the country is from burning fossil fuels for electricity, heat, and transportation – all of which can be powered by solar instead.Since solar panels don’t release greenhouse gas emissions into the atmosphere when producing electricity, they’re a good substitute for nonrenewable energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 50 pounds each year. As you can see, trading traditional energy for solar has so many other benefits apart from saving money. One of the primary ones is that you can help save the environment too.
