The Elizabethton Veterinary Clinic has “gone green” by installing a solar panel array on the south facing roof. Although it was not planned to be so, the Clinic building is facing so closely east to west that the southern exposure is only four degrees off due south. This made the southern facing roof an ideal location for solar panels.
The solar array on the roof of the Elizabethton Veterinary Clinic is a 13.36 kwh design that will produce about 15,000 kilowatt-hours during an average weather year. The amount of electricity produced by these panels will be done so at an average annual savings of 40,590 pounds of carbon dioxide emission pollution (that would be produced by a coal or oil fired electrical generator producing the same amount of electricity). Additionally, this electricity will have been produced with the elimination of 212 pounds of sulfur dioxide (causes acid rain) and 106 pounds of nitrous oxide (causes smog) per year from the atmosphere. The avoidance of this pollution is equivalent to removing 66 vehicles from the highway or to planting 99 acres of trees.
The Elizabethton Veterinary Clinic does not directly use the electricity produced by its solar panel array. The Clinic is still on the electrical grid and uses electricity directly off the grid just as it always has done. Through a separate set of feed back meters the electricity produced by the panels is fed directly back into the grid. The Clinic has no back up batteries. If the “electricity is off”, the Clinic has no power even though the panels may still be producing power and putting it into the grid.
The panel design and installation was done by Lightwave Solar Electric, LLC with the consultation of Beth McPherson of McPherson Environmental Resources. The ‘operation’ was commissioned and put on line 24 November 2010. At that time it was the largest solar array in the Tri-Cities. We are quite proud of the fact that we were able to install these panels and contribute to the reduction of air pollution.
