Methodology: How We Ranked the Best Solar Companies in Delavan
EcoWatch's solar experts analyzed each solar company in Delavan 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 Delavan
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 Delavan
For many readers, the decision of which solar company to go with depends on pricing. A few important factors that dictate how much it will cost to install solar panels on your home and how much money you could save over time are:
- Incentives: Those who buy and install a solar energy system this year can save 30% of their overall solar costs by taking advantage of the federal solar investment tax credit. You can also save about $19,000 on your energy bills over 20 years not including incentives.
- Your energy consumption: If your family uses a lot of energy, you'll reap more rewards from switching to solar.
- Choice of solar panels: The kind of solar panels you choose 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 space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
- The cost of energy for you: If your local power rates are especially high, there's a good chance you'll see a higher return on your investment in a solar panel system. In Delavan, you can save an average of $121 a month on your electricity bills.
Even though a solar panel system costs a decent chunk of money upfront, it can save you much more over time. The question of how much, though, depends on a number of factors, such as the size of your house and your current power bills.
