Options without a law
If you want solar that needs no grid permission, a portable power station charged by a panel is an option. Examples include EcoFlow models such as the DELTA 3 Max Plus (2,048 Wh, 3,000 W AC), DELTA Pro 3 (4,000 Wh, 4,000 W AC) and smaller TRAIL models; check the manufacturer for current specs and prices.
Homeowners considering larger, permanent systems should seek rooftop quotes from local installers and the utility because rooftop systems have different interconnection and permitting rules. If you want a quick estimate of what a small balcony kit would produce, use the calculator or compare models on the kits page.
- Portable stations: examples — DELTA 3 Max Plus 2,048 Wh / 3,000 W, DELTA Pro 3 4,000 Wh / 4,000 W (EcoFlow).
- Rooftop solar: get local installer quotes; interconnection rules differ from plug-in systems.

Questions
Is plug-in solar legal in Wisconsin?
There is no statewide plug-in solar law in Wisconsin as of October 14, 2026 (Bright Saver tracker). The absence of a law leaves plug-in systems in a gray area where utilities can impose interconnection reviews, permits and fees.
Can my utility require inspections or fees for a plug-in kit?
Yes. Bright Saver reports that utilities may require interconnection review, permits and fees for plug-in solar in Wisconsin because there is no statutory exemption or explicit consumer protection.
What can renters or HOAs do about a plug-in system?
Bright Saver states there are no explicit statutory protections for renters or homeowners associations in Wisconsin. Local lease terms, building rules or HOA covenants may still apply.
How much would an 800 W kit produce in Wisconsin?
The calculator gives, for an 800 W kit at the state population center: 738 kWh a year for vertical south-facing panels (416 kWh used at home, 319 kWh exported) and 1,060 kWh a year if tilted 30° south. At 19 cents per kWh (EIA, Jan–Jul 2026) the vertical case yields $79 a year in on-site value ($791 over 10 years, exports paid 0).
