Solar Design Services in Wisconsin
One engineering partner across the whole project lifecycle in Wisconsin. Proposal drawings to win the job, permit sets to get it approved, detailed engineering to get it built.
Client and engineer figures are portfolio wide across 15 countries. Installed capacity is Wisconsin specific.
WISCONSIN DESIGN SERVICES
Engineering capacity for the Wisconsin market
Wisconsin design work needs the utility tariff confirmed before sizing, because caps vary widely and a design above the cap cannot interconnect on those terms. Beyond that it is a cold-climate engineering market: snow as the governing structural case, and record low temperatures governing string voltage. The commercial segment routes through state plan review, which is worth planning for.
MARKET CONTEXT
The Wisconsin solar market
Wisconsin has grown steadily with strong support from municipal and co-operative programmes alongside the investor-owned utilities. The distinctive commercial reality is that net metering is not a statewide entitlement: terms and caps are set utility by utility through approved tariffs, and some municipal and co-operative caps are considerably lower than the large utilities. Checking the cap before sizing is essential rather than diligent, because a design above the cap simply cannot interconnect on those terms.
There is no statewide net metering mandate. Terms and caps are set utility by utility through approved tariffs, and some caps are much lower than others.
Residential runs under the statewide Uniform Dwelling Code while commercial routes through state plan review, so the two follow different approval tracks.
Snow load is the governing structural case, roughly 30 to 40 psf across much of the state and considerably higher in the Lake Superior snowbelt.
Cold winter temperatures raise module open circuit voltage, so string sizing must be checked against record low rather than average conditions.

INTERCONNECTION
Wisconsin utilities we design for
Export compensation decides how a system should be sized and whether storage belongs in the design, which makes it an engineering input rather than a sales detail.
| Utility | Territory | Export and compensation |
|---|---|---|
| We Energies | Milwaukee and southeastern Wisconsin, operating as Wisconsin Electric | Net metering under its own approved tariff, with a system size cap set in that tariff |
| Wisconsin Public Service | Green Bay and northeastern Wisconsin | Separate tariff with its own cap and terms, not aligned with We Energies |
| Madison Gas and Electric | Madison | Its own tariff terms and interconnection process |
| Xcel Energy | Western Wisconsin | Tariff-based net metering, distinct from its Minnesota territory terms |
| Municipal utilities and co-operatives | Numerous systems statewide | Individually set terms, with caps that can be considerably lower than the investor-owned utilities |
ENGINEERING CONDITIONS
What governs design in Wisconsin
These conditions decide the structural approach, the racking selection and often the layout itself. We verify them per site rather than applying a regional default.
Wind
Moderate, with open-terrain exposure on unshielded rural sites
Snow
A primary design driver, roughly 30 to 40 psf across much of the state and considerably higher in the Lake Superior snowbelt
Seismic
Negligible across Wisconsin
Also governing
Cold winter temperatures raise module open circuit voltage, so string sizing must be checked against record lows
Compliance scope in Wisconsin
- Uniform Dwelling Code for one and two family dwellings, administered statewide
- Commercial plan review through the state department with local enforcement variation
- Net metering terms set utility by utility through approved tariffs rather than a statewide mandate
- Lake-effect snow provisions near Lake Superior and Lake Michigan

Working with an India based partner on Wisconsin projects
We are based in Surat, Gujarat, and our Wisconsin clients are not. Our engineers work hours that overlap US time zones, so work sent at the end of your day is on your desk the next morning.
On code, the same engineers who produce CEIG approval drawings for an Indian utility also produce NEC compliant sets for US installers. Working across code frameworks daily is why Wisconsin specifics do not get lost in handoff. Work is covered by NDA and intellectual property transfers to you.
