Methodology: How We Ranked the Best Solar Companies in Koshkonong
EcoWatch's solar experts analyzed each solar company in Koshkonong 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 Koshkonong
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.
The Cost and Benefits of Solar in Koshkonong
For most homeowners, whether or not you should invest in a solar energy system depends the most on the cost. Some main factors that determine the cost of installing a solar panel system on your home and how much it could save you over time are:
- The amount of sunlight your roof gets: If your roof doesn't see much direct sunlight, your solar panels won't be able to make as much energy, which will give you lower savings on energy bills than someone with a roof that gets lots of sunlight.
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 30% of your total installation cost, your 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 $19,000 over 20 years with your solar panels, too.
- System size and type: Some models are more pricy than others, so the one you want can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
- Your current power bills: Solar panels can noticeably reduce, or completely eradicate, your utility bills. In Koshkonong, you can save an average of $124 a month.
Although a solar panel system costs a good 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 a number of factors, including the angle of your roof and your local electricity rates.

Environmental Impact of Switching to Solar in Koshkonong
Installing solar panels can have a positive effect on the environment. You may be asking yourself — how much does going solar help the environment anyway?

In Koshkonong, the average homeowner can lower their carbon footprint by 100 pounds a year after going solar. If you want to do what you can for the environment, you'll no doubt get that there are many benefits of adopting solar power other than just saving money on electricity.

What is the top solar panel installer in Koshkonong?
The highest-rated local solar company in Koshkonong is WindSoleil Solar and Wind Energy Services, with a rating of 5.00 stars.
What is the negative environmental impact of making solar panels?
Solar panels can be bad for the environment when manufacturers use toxic chemicals when they're made. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Making solar panels uses 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 getting solar panels?
Solar panels typically pay for themselves in about 8.9 years, but your solar payback period will vary depending on your utility costs. The higher your typical electricity bill, the faster your solar panel system will recoup your installation costs.
What are the different kinds of solar panels?
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, how much you're willing to spend and how much efficiency you're looking for.
