How the 30% Federal Tax Credit Works
The federal Residential Clean Energy Credit gives you back 30% of your total installed solar cost as a credit against your federal income taxes — not a deduction, but a dollar-for-dollar reduction in what you owe. It covers panels, inverters, wiring, mounting hardware, labor, permitting, and even battery storage. For a $21,560 system in Wisconsin, that is roughly $6,468.
The credit is non-refundable, but any unused portion can usually be carried forward to future tax years. You claim it with IRS Form 5695 for the year your system is placed in service. This is general information, not tax advice — confirm the details with a tax professional. Our solar tax credit guide walks through it step by step.
Net Metering in Wisconsin
Net metering decides what your utility pays for the excess power your panels send back to the grid, and it has a huge effect on payback. Wisconsin's posture in recent years is best summarized as net billing / reduced credit. These policies are among the most frequently revised in all of solar, and they often differ from one utility to the next, so treat this as a starting point and verify the exact buyback terms with your electric company.
