Meet The #1 Residential Solar Installer In Wisconsin

A Local Solar Energy Team Designed to Support You

Home Team Energy was founded because we saw a problem in the fast-growing solar industry: as companies expand, customer service often takes a hit. Teams get bloated, support is outsourced, and homeowners are left feeling like just another number.

We believe your energy needs are personal — and your service should be too.

That’s why we’ve made the choice to stay intentionally small. If we ever grow so big that our founder, Ryan Lettau, can’t personally meet with you, we’ll know we’ve lost what makes us different. Staying local and lean means you get custom, hands-on service every step of the way — before, during, and long after your system is installed.

We specialize in residential solar installations across Southern Wisconsin, and we handle everything in-house — from design to permitting to installation — using our own skilled solar crew. That’s how we ensure every solar energy system is done right, with consistent quality and care.

When you go solar with us, you’re not just a customer — you’re part of the Home Team.

Meet Ryan Lettau, Owner of Home Team Energy

Ryan established Home Team Energy in 2019 after a decade of experience in the solar energy industry. After graduating from Milwaukee School of Engineering in 2008 with a degree in Architectural Engineering, Ryan first worked for a roof consulting company where he incorporated solar into the existing business model.

After that, he moved on to a solar development company in 2010 and saw how rapid expansion led to a collapse in attention. Larger teams with more jobs over a larger region meant less time per client.

So in 2019, with a garage full of solar panels, Ryan started a family business called Home Team Energy. His wife Shelly worked with permitting and logistics, and his young sons help with clean-up and washing the trucks. Together, they began a company designed to maximize support and service for their clients.

After seeing how businesses can focus more on profits over people, Ryan—and now the team too—is on a mission to show that hard work, integrity, and treating people with dignity and respect should be the real focus of a successful business.

In 2022, the Lettau Family added a Tesla Model Y to their fleet, which is powered by their roof mounted solar array!

Home Team Energy has installed over 13,000 Solar Panels Across more than 700 Residential Solar Installations.

If I could describe my experience working with Home Team Energy, based in Brookfield, Wisconsin, in just one word, it would be WOW!!! It was truly an amazing experience from start to finish. Home Team Energy Company Recently, I decided to transition to solar and began educating myself on the process. After building several financial models and analyzing energy price trends over the last five years, I determined it was the right time to move forward. During my research, I focused on identifying high-quality local installers rather than national or regional companies, and I am very happy I landed on Home Team Energy. Working with Ryan was an absolute pleasure. He was not only professional and genuine but also offered the best price among all the companies I vetted. He was incredibly flexible regarding payment terms, making the financial side of the agreement seamless. After signing the contract, the Home Team Energy team moved with impressive speed, completing the installation of my solar panels within two weeks. They also expertly handled all the regulatory and permitting requirements, which made the entire process stress-free. If you are considering going solar, I highly recommend Home Team Energy. They provide a fantastic combination of competitive pricing, local expertise, and efficient, reliable service.

 Trustindex verifies that the original source of the review is Google. Home Team did our solar and back up battery installation this past March. From the initial inquiry all the way through installation and final commissioning, Ryan and his team were fantastic to work with! We could not be more pleased with the results. Our electric bills have been $0 and we are actually selling electricity back for a credit. The battery system is easy to use, efficient and provides a great peace of mind during recent storms. Thanks Home Team!!

 Trustindex verifies that the original source of the review is Google. Had a great experience with Home Team Energy Company installing solar panels. The whole process was easy and well organized, and communication was solid from start to finish.  There was no pressure during the entire process (most of the rest of the installers in the are were very pushy or didn't respond to communications in a timely manner). Ryan and his crew were awesome.  The panels were installed during the coldest stretch of the year, but that didn't stop the guys from Home Team from completing the project.  It was impressive (and surprising) to see everything installed in only 2 days. The install looks clean and professional, and they made sure everything was working and explained before wrapping up. Overall, really happy with the work and the experience.

 Trustindex verifies that the original source of the review is Google. After researching over a dozen solar installers, I chose Home Team Energy—and I’m glad I did. They were by far the most honest and transparent team I spoke with. They took the time to walk me through every aspect of the system, including how net metering works with WE Energies, which was a huge help. One thing that really stood out was their advice around battery storage. Rather than upselling me, they explained why a battery wouldn’t improve the ROI of the system given how net metering works locally. That kind of integrity is rare. Being a local company gave them an edge in navigating the utility setup, and their white-glove service meant they handled everything—from permitting to installation to commissioning—with professionalism and care. While the install took a bit longer due to coordination with other home projects, they still completed and commissioned the system ahead of their original commitment. I would, without hesitation, recommend Home Team Energy to anyone considering solar.

 Trustindex verifies that the original source of the review is Google. Contractors are often tough to deal with, but I can’t say enough good things about my experience with Home Team Energy. Sales & Proposal: Having worked for a competitor solar company one summer, I saw firsthand all the fraudulent sales tactics and inflated pricing, not just for equipment, but also for finance fees and interest. That experience turned me off to solar for years. Ryan’s honest, straightforward, and significantly more cost-effective proposal is what finally got me on board. He even provided a detailed spreadsheet showing how much WE Energies has raised its rates year after year, between 6% and 10% annually over nearly the past decade. Seeing that trend really drove home how valuable this system will be long-term. Installation & Management: The electricians, installers, and management team were true professionals. They walked me through every step, answered all my questions, and made sure I understood the process. The installation itself was just as impressive, the electricians never rushed, instead taking the time to make the system blend seamlessly into my home. Communication was clear and consistent from start to finish. Equipment I went with Enphase IQ8X Microinverters paired with REC460A Pure-RX panels. The Enphase app is excellent, and the all-black panels look great on the roof. I probably could have squeezed in 2–3 more panels, but Ryan saved me from overspending since I was already at 120% offset. Thanks to my house layout, all panels sit on the garage and covered patio, meaning if a roof leak ever did occur, it wouldn’t affect the main living space. WE Energies’ new bi-directional meter also simplified the install and gave the system a clean, integrated look. Post-Install Service: Home Team is proactive about setting customers up for success in every facet. After my first month of production, WE Energies billed me correctly. In the second month, WE Energies made a mistake, but Ryan and Brian stepped in big time. They went above and beyond, coaching me through the best way to get resolution from y energy provider. Final Thoughts: If you’re considering solar, I couldn’t recommend Home Team Energy more highly. They truly care about their customers and make the entire experience stress-free and beneficial. Since you made it this far in my review, here’s my own sales pitch: Home Team offers a referral bonus. If this review helped you, I’d be happy to split it with you, just mention my name when you contact them or reach out to me to connect!
