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.
