The District Department of the Environment's Renewable Energy Incentive Program (REIP) supports the adoption of solar photovoltaic and thermal technologies on properties throughout the District of Columbia.

On February 23, 2009, the program began providing rebates to eligible applicants to assist in the installation of solar (photovoltaic) renewable energy system. Projects may include, but are not limited to, the installation of systems on single and multi-family dwellings, as well as commercial and institutional buildings.

In April, 2012 the program began providing rebates to eligible applicants to assist in the installation of solar (thermal) renewable energy systems.

Incentive Structure

Solar Thermal incentives are based on flat rate percentage of installed system cost:

  • 20% of total system cost up to $6,000 for non-residential thermal systems

Rebates for non-residential solar thermal systems are capped at a maximum of $6,000. Only one rebate per eligible system- type may be requested for each unique installation address, per program year.

Photovoltaic incentives are based on the combined system rating in kilowatts of Direct Current (DC) output:

  • $0.50/watt for photovoltaic systems, with a cap of  $10,000 (equivalent to a 20kW)

Rebates for photovoltaic systems are capped at a maximum of $10,000 (at 20 kilowatts capacity or greater) for each unique installation address, per program year.


DDOE supports the adoption of solar technology on properties throughout the District of Columbia.


These program operates on a first-come, first-served basis and incentive requests are dependent upon funding availability.
