Is solar worth it in Wisconsin in 2026?

With an average electricity rate of 17.1¢ per kWh and 4.3 peak sun hours per day, Wisconsin homeowners are in a good position to benefit from solar panels. A typical 8kW system will produce around 10,044 kWh per year — enough to offset a significant portion of a typical Wisconsin home's electricity usage.

At current electricity rates, that production saves approximately $1,717 per year. Over 25 years — the standard panel warranty period — the projected net profit after recouping the system cost is around $26,125.

What affects solar savings in Wisconsin?

Every homeowner's solar savings are different. In Wisconsin, the key variables are:

Electricity rate (17.1¢/kWh): Wisconsin's above-average electricity rate means every kWh your solar panels produce is worth more than in cheaper-electricity states — this is one of the strongest drivers of fast payback.
Peak sun hours (4.3 hrs/day): Wisconsin's sun hours are below the national average. This is offset by choosing an appropriately-sized system and optimising roof orientation. South-facing roofs at 20–30° pitch perform best.
System size (8kW typical): The right size depends on your electricity bill. A $150/month bill typically requires a 6–8kW system to offset 80–100%. Use our System Size Calculator to find your exact target.
Roof type and orientation: South-facing roofs at 30° pitch are ideal. West-facing roofs produce 15–20% less but may generate more electricity during peak-price afternoon hours, improving time-of-use savings.
