Iowa solar notes
Iowa maintains net metering with optional inflow/outflow billing at MidAmerican and Alliant; low electricity rates mean payback relies on good production.
Heads up: the 30% federal tax credit for purchased home solar ended Dec 31, 2025. Leased/PPA systems may still qualify through 2027, and Iowa may offer its own incentives — check locally.
