Methodology: How We Ranked the Best Solar Companies in Lafayette
EcoWatch's solar experts analyzed each solar company in Lafayette 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 Lafayette
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 Lafayette
Even though solar panels can help save you money on utility bills over time, it's important to take into consideration the startup costs. There are quite a few factors you should take into consideration when trying to figure out the overall cost and how much you can save, such as:
- Your household's power bills: Based on the fairly high monthly electricity bills in Lafayette, you could save about $1,100 a year with solar.
- Your city: This affects how much sunlight your roof gets, which helps determine how many panels you need.
- Choice of solar panels: The type of solar panels you buy 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 opt for a higher number of more affordable panels.
- Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 30% of the cost of your solar system installation from your federal taxes. Additionally, not including incentives, you can save about $33,000 over 20 years on your energy bills.
Solar is a profitable investment for most homeowners. You can produce your own energy instead of paying for it from a utility company and make use of solar incentives, all while helping preserve the environment.

On top of the federal solar investment tax credit, there are also some state- and city-level incentives, which in the majority of cases, can be claimed in addition to the federal incentive, so you can save even more. Take a look at our article on solar incentives to learn what incentives are available to you.
Environmental Impact of Switching to Solar in Lafayette
Swapping traditional energy for solar is a powerful way to do your part for a cleaner and more sustainable future. You may be curious — how much do solar panels help the environment anyway? The average person has a sizable carbon footprint. Between their car, which is responsible for over 10,000 pounds of carbon dioxide emissions a year, and electricity for their home, it can be overwhelming to think about what to do. Going solar is a practical thing you can do to help. Once you go solar, your carbon emissions can be reduced by about 50 pounds every year. The good things about solar power are abundant — just like solar power is! That's why so many homeowners have been happy with making the switch to solar.

What are the pros and cons of going solar?
The main advantages of solar power are that it can lower or, in some cases, completely cut your electricity bills, raise the value of your home and bring down your carbon footprint. The main disadvantages are that solar panels can be expensive to install, you may not save as much if you don't use a lot of electricity and it doesn't work for all roof types and locations.
Is it worth installing solar panels on my home?
Solar panels can be a beneficial investment for lots of homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your power bills are already fairly low, solar panels might not be for you.
What is the best kind of solar panel?
There are three main types of solar panels: monocrystalline, polycrystalline and thin-film. In regard to efficiency and price, monocrystalline has the highest for both, then polycrystalline, and then thin-film. The best choice for you is highly influenced by the layout of your roof, your budget and desired energy output.
