Pennsylvania schools that adopted solar power say their arrays are performing as expected, in some cases generating 100 percent of building electricity.
In the Bethlehem Area School District, five of 22 schools have solar panels.
The district broke ground on the entirely grant-funded projects in late 2010. Each installation was designed to minimize the disturbance to neighbors.
District engineer Arif Fazil, of D'Huy Engineering Inc., said the panels are producing electricity as estimated.
