Key Advantage
State and utility incentives may still reduce net system cost. The federal 25D ITC expired Dec 31, 2025 — check your state's energy office and DSIRE.org for active programs in District of Columbia.
Watch Out For
Verify utility net metering policies — export credit rates vary significantly by utility, and a net-billing tariff pays less than the retail rate.
