Methodology: How We Ranked the Best Solar Companies in Sussex
EcoWatch's solar experts analyzed each solar company in Sussex 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 Sussex
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 Sussex
When deciding on a solar company, most homeowners or business owners wonder about the costs above all.There are quite a few factors you should take into consideration when determining how much it will cost and how much you can save, such as:
- Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 0 of the cost of installing your solar panel system from your taxes. Plus, not including incentives, you can save about $21,000 over 20 years on your energy bills.
- How much you spend on energy: If your local utility rates are especially high, there's a good chance you'll have a higher return on your investment in a solar system. In Sussex, you can save an average of $1,295 a month on your electricity bills.
- The kind of solar panels you have the money for: This depends on how much you’re willing to spend upfront.
- Typical energy usage: The more electricity your household uses on average and the higher your current electricity bills are, the more money you could save by switching to solar.
There are many great benefits of solar even with the upfront cost of installation. It can help the planet and your bank account. In addition, it can increase the value of your home, resulting in even more benefits if you want to sell your home later.

Solar Incentives in Sussex
One of the great things about installing a solar panel system is earning federal and potentially state incentives.On top of the federal tax credit incentive, there are also some local benefits, which in the majority of cases, can be claimed in addition to the federal incentive, so you get to save even more. For more information about incentives for homeowners in Sussex, see our article on solar incentives.
Environmental Impact of Switching to Solar in Sussex
One of the most compelling reasons to tap into solar energy is to reduce your reliance on traditional energy sources like burning fossil fuels, which are hazardous for the environment.Something many might be asking themselves is how much can they really help preserve the environment by switching to solar power anyway? One thing you should consider is your overall carbon footprint. For example, if you spend a lot of time on the road and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions.When you go solar, your carbon dioxide emissions can be cut by about 90 pounds a year. Since energy from the sun is renewable and makes electricity without CO2 emissions, making the switch to solar power is one easy step you can take to help preserve the planet.
