DC Solar Property Tax Exemption

The DC Solar Property Tax Exemption removes a tax burden solar owners would otherwise carry, one of District of Columbia's DSIRE-tracked solar incentive programs. Eligibility is scoped to residential customers, with a stated benefit of Property tax exemption. DSIRE lists no scheduled sunset, though enabling legislation and appropriations can still be revised year to year.

That baseline is slower than most states, which raises the stakes for every incentive on the table. District of Columbia averages 4.4 kWh/m²/day of usable sunlight and residential rates of 19.5¢/kWh, producing an estimated 7,709 kWh/year and $1,503 of annual utility offset on a typical 6 kW system costing $19,500. That baseline already implies a 13-year simple payback and a 25-year modeled net of roughly $18,075 before this incentive - every dollar this tax exemption delivers compresses that payback further.

A handful of other levers are worth checking alongside this one. District of Columbia has 5 solar incentive programs indexed in DSIRE, including adjacent options like DC Net Metering, DC Solar for All Program, DC Solar Renewable Energy Credits (SRECs). The state's net-metering policy is classified as full, which governs how excess generation is credited and often decides whether a given program is worth claiming for a specific household.
