Solar Installer pay in Wisconsin, bottom to top
BLS calls this group solar photovoltaic installers: the crews who mount, wire and set up solar panels on roofs and on the ground.

| 10th percentile | $21.59 | $44,910 | $20.00 |
| 25th percentile | $23.02 | $47,880 | $22.45 |
| Median | $23.93 | $49,770 | $25.55 |
| 75th percentile | $31.41 | $65,340 | $30.23 |
| 90th percentile | $41.18 | $85,650 | $38.45 |
| Average (mean) | $27.96 | $58,150 | $27.84 |
From the bottom tenth ($21.59) to the top tenth ($41.18), the top of the scale pays about 1.9 times the bottom in Wisconsin, close to the 1.9 times spread for solar installers nationwide.
Both ends of the scale beat the national figures: $21.59 against $20.00 at the bottom tenth, and $41.18 against $38.45 at the top.
The average wage, $27.96, sits 17% above the median. A smaller group of higher earners pulls the average up, so the median is the better guide to what a typical solar installer makes.

What a solar installation company in Wisconsin should charge
A lower wage helps the price less than you might expect, because the overhead does not shrink with it. Here is a solar installation company in Wisconsin paying the state median of $23.93, on the labor rate calculator's starting numbers: 40-hour weeks, 10 paid days off, 2 unbilled hours a day, 7.65% payroll taxes, $90,000 a year of overhead and 15% profit.
| Step | Math | Result |
|---|---|---|
| Paid hours | 40 × 52 | 2,080 |
| Hours at work | 2,080 − 10 days × 8 | 2,000 |
| Billable hours | 2,000 × 6 ÷ 8 | 1,500 |
| Labor cost | $23.93 × 2,080 × 1.0765 | $53,582 |
| Break-even rate | ($53,582 + $90,000) ÷ 1,500 | $95.72 |
| Rate with 15% profit | $95.72 ÷ 0.85 | $112.61 |
That is $112.61 per billable hour, 4.7 times the wage, and $2.84 less than the $115.46 the same math gives at the national median wage.
Paying the 75th percentile instead, $31.41 in Wisconsin, to hire and keep experienced people raises the rate to $125.75.
A cheaper crew saves less than it seems: at the 25th percentile wage of $23.02, the rate only drops to $111.02.
At this wage, overhead is most of the price: $60 of every billed hour goes to it before anyone is paid. Spreading the same overhead over more billable hours, with a second person or less drive time, brings the rate down fastest.
