Methodology: How We Ranked the Best Solar Companies in Jefferson
EcoWatch's solar experts analyzed each solar company in Jefferson 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 Jefferson
Below are some the criteria we examined specifically for Wisconsin 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.

You qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar panel system. You can also possibly stack the ITC with other local rebates and benefits.

Environmental Impact of Switching to Solar in Jefferson
One of the reasons so many people consider adopting solar energy is to help reduce their environmental impact. A question many homeowners might have in mind is how much can they really help save the environment by switching to solar power anyway? Using clean energy for electricity in place of using nonrenewable energy is a good way to reduce carbon dioxide emissions if you want to help reduce Jefferson's sizable level of greenhouse gas emissions. Because solar panels don't release CO2 emissions into the atmosphere when generating electricity, they're a good alternative to traditional energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 80 pounds each year. The great things about solar power are abundant — just like solar power is! That's why so many Jefferson residents have been happy with committing to solar.

Which solar power company is the best in Jefferson?
The highest-rated local solar company in Jefferson is WindSoleil Solar and Wind Energy Services, with a rating of 5.00 stars.
Are solar panels actually eco-friendly?
Solar panels can be bad for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to recycle safely once they've reached the end of their lifespan. Solar panel manufacturing uses a lot of energy as well. The energy payback period is about 1 to 4 years.
Is it worth installing solar panels on my roof?
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 enough sunlight or your energy bills are already fairly low, solar panels might not be for you.
How much solar panel capacity do I need for my house?
Solar panel capacity is how much energy the panels can generate under ideal conditions (a sunny day around noon). The average household requires between 20 and 35 panels to cover their typical energy usage.
