Your solar PV system can save money for you and help mitigate climate change. Furthermore, you can sell solar renewable energy credits for extra income. 

Average Cost of Solar Energy Systems

The average cost of a solar PV system has dropped over 80% in the past decade. The average solar system cost dropped 45% per Watt of DC installed in the past five years. Currently, you can expect to pay $3.31 per watt to install solar panels. This price is further brought down by significant solar incentives and the federal tax credit.

Solar Renewable Energy Certificates (SRECs)

Your solar panels produce solar electricity whenever they are exposed to sunlight. A kWh of solar panels can produce as much as 0.85 MW of energy per year in year. For each MW that you produce, you will get one SREC. You can sell these SRECs on the SREC market. Thanks to a rigorous RPS in DC, you can expect to get anywhere between $380 and $435 per SREC.

Net Metering in Washington DC

Net Metering gives you full retail rate credit for any unused kilowatt-hour you send to the grid.
