How Solar Panels Work in Wisconsin
Solar energy systems harness the power of the sun through a sophisticated yet straightforward process, with special considerations for Wisconsin's unique climate.
Sunlight Absorption
Photovoltaic cells in the solar panels capture sunlight and convert it to energy.
Wisconsin Note: Despite our northern location, Wisconsin receives 4.5 peak sun hours daily on average, comparable to parts of Florida during summer months.
Electricity Generation
Silicon cells convert sunlight to direct current (DC) electricity.
Wisconsin Note: Even on cloudy Wisconsin days, modern panels still generate electricity at 10-25% of rated capacity from diffuse light.
Inversion Process
Inverters transform DC to alternating current (AC) electricity that can power your home.
Wisconsin Note: Our inverters are rated for Wisconsin's temperature extremes from -30°F to 120°F.
Power Distribution
AC electricity powers your home or business through your existing electrical panel.
Wisconsin Note: Seamlessly integrates with existing Wisconsin utility infrastructure.
Grid Connection or Storage
Excess energy flows to the grid for credit or into battery storage for later use.
Wisconsin Note: Critical for Wisconsin's occasional grid outages during winter storms.

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 Winter Solar Solutions
- Our systems include snow-shedding panel placement and optional snow guards
- Cold-rated components ensure operation in sub-zero temperatures common in Wisconsin winters
- Battery backup systems provide critical power during Wisconsin ice storms and grid outages
Seasonal Solar Production in Southwest Wisconsin
*Based on actual production data from Ethos Green Power installations in Southwest Wisconsin. A typical 6 kW residential solar array in Wisconsin generates approximately 8,348 kWh annually.

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.
