How does solar work?
Understanding solar energy for your Wisconsin home or business
Benefits of Solar Energy in Southwest Wisconsin
Before diving into how solar technology works, let’s explore why Southwest Wisconsin homeowners and businesses are increasingly turning to the sun for their energy needs.
Economic Benefits
Properly sized systems can offset over 95% of household consumption, effectively eliminating most electric bills
Typical ROI for Wisconsin solar systems: 10-13 years, with 25+ years of energy production
Protection from utility rate increases (Wisconsin electricity rates have risen 2.6% annually over the past decade, with sharp increases in the past few years)
Environmental Benefits
Each 10kW system in Wisconsin offsets approximately 10 metric tons of CO₂ annually
Equivalent to planting 240 trees each year on your Wisconsin property
Reduces dependence on out-of-state energy sources, keeping your environmental impact local
Property Value Benefits
Wisconsin homes with solar typically sell for 4.1% higher than comparable properties
Solar installations are an attractive feature for homebuyers seeking lower utility costs and energy independence
Provides energy independence and resilience against grid outages

Solar Performance in Wisconsin’s Climate
Wisconsin Weather and Solar Production
Wisconsin receives 4.5 hours of peak sunlight daily on average (more than Germany, the world’s leading solar market). Modern solar panels actually perform better in cold temperatures due to increased electrical conductivity when ambient temperatures are below 77°F.
What surprises many homeowners is that snow reflection can increase solar production by up to 15% through the “albedo effect,” where sunlight reflects off snow onto panels.

Wisconsin Customer Success Stories
Real Results from Your Southwest Wisconsin Neighbors
The Schippers, La Crosse County
System: 16.2kW ground mount solar installation
The Schippers were tired of paying for the high cost of electric heat and were thrilled solar could help cut costs while also providing environmental stewardship. Special Note: They supercharged their savings by upgrading their three season room with a mini split heat pump.
Monthly Electricity Costs
Before Solar: $210 Monthly electric bills
After Solar: $15 Monthly connection fee, plus $250 annual electricity costs
Farmer, Vernon County
System: 23kW ground-mount solar array
This farmer sought us out to reduce operational costs while staying true to their sustainable farming values. Their farm in Vernon County had ample open space for a ground-mounted system.
Return on Investment (ROI)
System will pay for itself in 5.3 years after incentives, with an expected lifetime savings of over $112,000.
Wisconsin Solar FAQs
How do solar panels perform in Wisconsin winters?
Modern solar panels actually perform more efficiently in cold temperatures due to increased electrical conductivity. While production decreases during shorter winter days, panels often outperform specifications during cold, sunny winter days. Snow typically slides off panels mounted at our recommended angles, and any accumulated snow melts quickly as panels warm. On cloudy winter days, panels still generate 10-25% of their rated capacity.
What happens during Wisconsin power outages?
Standard grid-tied systems will shut down during outages for safety reasons. However, our battery backup solutions provide continuous power during outages—critical during Wisconsin’s winter storms. Battery systems can be sized to power essential loads for days or your entire home, depending on your needs.
What about Wisconsin utility rules and regulations?
As a local installer, we’re experts in Wisconsin’s net metering policies, interconnection requirements, and utility-specific programs. We handle all paperwork with your utility provider, whether it’s Vernon Electric Cooperative, Xcel Energy, Alliant, or others serving Southwest Wisconsin.
How much maintenance do solar panels need in Wisconsin’s climate?
Very little. Rain and snow naturally clean panels in most cases. We recommend an annual inspection, which we provide as part of our service package. Our systems are engineered for Wisconsin’s freeze-thaw cycles, heavy snow loads, and occasional hail.
