While many of us express concern that we do not see as many solar collectors on Virginia roof-tops as we would like, the Commonwealth is showing significant progress on turning sunlight into electrical energy. As with any major change there are some hazy areas that need to be considered as well.
According to the Solar Energy Industries Association (SEIA) as reported in the August 2018 issue of Virginia Business magazine, Virginia currently ranks 17th nationally with 631.3 megawatts of installed solar capacity. The ranking is a significant jump from 2016 when the state ranked 29th nationally. Even with the advanced standing, only 0.59 percent of the state’s electricity comes from solar. By way of contrast, North Carolina is second in the nation in installed solar capacity with 4,412 megawatts brought about by generous tax incentives. For North Carolina that is nearly five percent of their electricity supply.
Virginia’s future with solar appears bright with 59 notices of intent with the Department of Environmental Quality to install 2,646 megawatts of solar according to the Virginia Business article. Driving the expansion of solar energy is a sharp drop in price from $96 in 1970 to 40 cents per kilowatt this year and an insistence on the part of technology giants like Amazon, Microsoft, Google and Facebook, all of whom have a presence in Virginia, that their electric power come from solar systems. The Grid Transformation and Security Act passed by the General Assembly this year requires 5,000 new megawatts of solar and wind energy to be developed. Included in that total is 500 megawatts of small, roof-top panels.
Middlesex County Public Schools opened this year with two of its three schools powered by solar energy. Although a small, rural school system, Middlesex has the largest ground-mounted solar system of any school division in the state and is expected to save over two million dollars per year. Excess electricity generated is sent to the grid for credit for any electricity the schools takes from the grid at night through a net-metering arrangement.
Some shadows along the way can be expected with such a massive shift in the way electricity is produced. It takes about eight acres of land for each megawatt produced. Solar farms take up large amounts of land. Just last week the Culpeper County Board of Supervisors voted to deny a conditional-use permit for a 178-acre utility scale solar facility in the County. The supervisors indicated that they had questions about the project for which they did not receive adequate answers. One factor is likely to have been the results of a study by the American Battlefield Trust that indicated the project would be visible from some of the half-dozen signal stations around Culpeper County that were used during the Civil War to detect troop movement. The County depends on a high level of tourism based on its Civil War battlefields and apparently does not want to jeopardize its attraction to Civil War buffs.
The clouds will pass, and Virginia is on its way to a bright future with solar energy.
