What Are The Top 5 Solar Companies In Wisconsin?

Finding the best solar panel installation companies in Wisconsin can be a real challenge.

We know just how tough it is because we’ve actually looked at every renewable energy contractor in the state. Then, we narrowed down all the excellent solar power companies we found to the top five in the table below.

We base our selections on several aspects of each company, including their warranties, pricing, financing, customer reviews and Better Business Bureau ratings, among others.

Company Solar Services Warranty Options BBB Rating Year Founded 
All Energy Solar Solar panel and battery sales and installation; electrical work; system monitoring 25 to 30-year production warranty; additional equipment-specific warranties A+ 2009
Sun Badger Solar Solar panel, battery and EV charger installations; system maintenance 25-year workmanship and equipment warranties A- 2018
Arch Electric Solar panel, battery and EV charger installations 25-year manufacturer warranty; 5-year workmanship warranty A+ 2003
Everlight Solar Solar panel and battery installations 25-year product warranty; 10-year workmanship warranty A+ 2017
Olson Solar Energy Solar panel and battery sales and installation 25-year production warranty A+ 2017

You may notice we don’t include popular companies like Vivint Solar in our reviews. The exclusion was purposeful due to problems with lawsuits and other issues.

What Criteria Did We Use To Evaluate Wisconsin’s Solar Panel Companies?

Our seasoned team of solar professionals at EcoWatch understands exactly what a solar energy system company needs to excel. To find the best companies, we use our tried and true solar vetting process, which includes a deep look at the following aspects.

Warranty

A solar installation company that is confident in its products is much more likely to back its installations with excellent warranties. The best companies often provide excellent workmanship guarantees and solar panel systems with a decent manufacturer’s warranty. A solar energy system is a costly investment that should be warranted for many years to come.

Year Founded

old house with solar panels on the entire roof Older, well-established companies tend to offer an abundance of experience and knowledge accumulated over decades of service.  While some younger companies may be able to rival their older comrades, there’s something to be said about years of experience.

For example, experienced companies have project managers that have “seen it all” and can keep your installation on track no matter what’s thrown at them.

Dozens of “fly-by-night” solar companies are popping up all around the U.S., many of which are inexperienced and unqualified to do the job effectively. For this reason, we pay attention to the year the solar installation company was founded.

Services Offered

Some solar companies offer several related services, such as electrical or roofing services. This can benefit homeowners in the long run, as they won’t have to outsource any portion of the process to a subcontractor.

Solar Panels Offered

Leading solar companies tend to offer an array of high-quality solar panel brands in varying sizes. Plus, offering various types of solar batteries, inverters, etc., to complement the PV system is a huge plus. These companies can take on any project, no matter how big, small or unique.

Solar Pricing and Financing

Top solar companies offer competitive pricing and excellent financing options. Since many homeowners cannot afford the upfront purchase price, financing is often an important component of their top choice. The best solar companies offer several types of financing to accommodate the needs of varying budgets.

Additionally, the best solar companies offer competitive pricing. Although they offer pricing that will rival their competitors, they don’t sacrifice quality, workmanship or anything else in the process.

Industry Affiliations

We also note each solar installation company’s affiliations within the industry – such as SEIA or NABCEP certifications. Often, companies are affiliated with or will partner with other companies within the industry.

While this may not seem like an important aspect, we take note of this because it indicates a commitment to contributing to the solar industry and the shared values and goals of the sustainability community.

Companies who make an effort to forge these relationships are more likely to last longer, have better service and create a positive lasting impact on the area they service.

Size of Company

The company’s size can play a role in how effectively it can serve you. Substantial or national companies tend to have large teams, which may enable them to help install your solar array system more quickly or efficiently.

However, some small companies perform equally as well as their larger competitors, serving you equally as quickly and efficiently. Regardless, this is a factor we keep in mind as we research the options.
