The map was the first of its kind in Northern Virginia. </span><font size='4'>This GIS layer and the solar map were created in 2016 as part of the <a href='https://solarizenova.org/' target='_blank' rel='nofollow ugc noopener noreferrer'>Solarize NOVA</a> program and continues to be used today for Solarize Nova. Solarize NOVA began in 2014 as a community-based outreach initiative to bring solar power to people in their homes and businesses throughout Northern Virginia through our solarize campaigns. Solarize NOVA is sponsored by the <a href='https://www.novaregion.org/' target='_blank' rel='nofollow ugc noopener noreferrer'>Northern Virginia Regional Commission</a> (NVRC), managed by the <a href='https://leap-va.org/' target='_blank' rel='nofollow ugc noopener noreferrer'>Local Energy Alliance Program</a> (LEAP), and works in partnership with local governments and other supporters.'<br /></font></div></div><div><font size='4'><br /></font></div><div><font size='4'>The feature layer provides potential solar system sizes and the potential electricity savings based upon the current electric rate of 11 cents per kilowatt-hour. CO2 calculations are based upon a formula published on the EPA's Greenhouse Gas Equivalencies Calculator. All building roofs under 250 square feet are excluded from consideration, as they are too small for a solar PV array. Roof slopes above 50 degree are excluded because they are too steep for a solar PV array. Roof orientations of north, northeast, and northwest are excluded due to insufficient sun exposure. Shading is considered based off of LiDAR data, which may or may not reflect current conditions.
