We installed 24 Qcells North America modules with Enphase Energy microinverters for this rural homeowner, offsetting 102% of their energy needs. We used the existing conduit from the house to tie in our barn-mounted solar and save on electrical costs. We’ll also be installing a new heat pump soon. If the homeowner decides to add more panels, their east-west-facing pole barn roof offers plenty of room for expansion.

In case you missed it, Ron was featured in this In Business Madison article about our work to help folks recover from the extreme spring storms.
🔗 https://www.ibmadison.com/industries/madison-businesses-city-keep-busy-after-spring-storms/article_a631e631-76b3-4af7-9a1d-6e4d344b9661.html
The spring storm that hammered parts of Madison with hailstones — resulting in damaged roofs, shattered car windows and other destruction — will keep the area’s construction crews, auto glass and insurance companies busy in the weeks ahead.
I had a front-row (well, basement level) seat to the pummeling, which resulted in a broken window and two cars pockmarked with quarter-sized dents and a damaged windshield.
In the wake of the storm, on the near east side, representatives of roofing companies knocked on doors and dropped off fliers offering free inspections. What had been a neighborhood blanketed with golf ball-sized hail days earlier was now a mix of trucks, ladders and repair workers.
“For us, it’s unprecedented in 24 years of business,” Ron Chester, general manager at Full Spectrum Solar, told In Business Madison's Louis Livingston-Garcia. “We’ve installed over 50,000 solar panels, and up until the events of April 14th, we can think on one hand how many solar panels couldn’t handle your regular hail.
“The hail we witnessed on the 14th was absolutely next scale, next size, and we’re receiving a lot of damage reports.”
