Solar panels in La Crosse, WI
Roofs in La Crosse get about 1,522 hours of usable sunlight a year — less than 55% of the cities we've measured. Here's what that means in cost, savings and payback, using real rooftop data rather than a national average.
Check your specific roof in La Crosse → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical La Crosse solar system costs
A 21-panel system (8.4 kW) is about right for an average La Crosse home using 10,800 kWh a year. It would produce roughly 10,867 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,140 | $6,384 | $716 | 8.9 yrs |
| 12 panels | 4.8 kW | 6,210 | $9,576 | $1,074 | 8.9 yrs |
| 16 panels | 6.4 kW | 8,280 | $12,768 | $1,432 | 8.9 yrs |
| 20 panels | 8 kW | 10,350 | $15,960 | $1,790 | 8.9 yrs |
| 26 panels | 10.4 kW | 13,454 | $20,748 | $1,983 | 10.5 yrs |
Notice that payback barely improves as systems get bigger, and eventually gets worse. That's because you can only save money on electricity you were going to buy anyway. Once a system covers your usage, extra panels mostly generate exports at a much lower rate.
Why La Crosse gets 1,522 sun hours
That figure comes from Google's analysis of real rooftops across La Crosse — it already accounts for shading from trees, chimneys and neighbouring buildings, which is why it's lower than the raw "hours of daylight" figures you'll see elsewhere. An unusually open, unshaded roof in La Crosse reaches about 1,612 hours, roughly 6% better than typical.

When La Crosse actually produces
Annual totals hide the thing that catches people out: 38% of La Crosse's yearly sunlight arrives in May–July, and just 12% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 61 | |
| Feb | 87 | |
| Mar | 121 | |
| Apr | 158 | |
| May | 186 | |

| Aug | 169 | |
| Sep | 134 | |
| Oct | 97 | |
| Nov | 67 | |
| Dec | 54 |
La Crosse produces about 3.7× as much in Jun as in Dec — a normal mid-latitude swing. Expect real winter shortfall and summer surplus rather than steady year-round output.
The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at La Crosse's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

La Crosse solar questions
How many solar panels do I need in La Crosse?
About 21 panels for an average home using 10,800 kWh a year. La Crosse roofs get 1,522 usable sun hours, so each 400W panel produces roughly 517 kWh annually. A typical La Crosse roof fits about 39 panels, so check your usable roof area before assuming that many will fit.
Is solar worth it in La Crosse?
At 17.3¢/kWh and 1,522 sun hours, a typical system pays for itself in about 9 years and returns roughly $30,025 over a 25-year panel life. That is a solid return, and it improves further if electricity prices rise. Exported power earns full retail credit here.
How much do solar panels cost in La Crosse?
A 8.4 kW system costs about $23,940 before incentives and $16,758 after the 30% federal tax credit. That works out near $2.85 per watt installed. Roof pitch, shading, electrical panel upgrades and equipment choice move the price most, which is why quotes for the same house can differ by thousands.
