SunPower and HP indtalled HP’s printer manufacturing facility in San Diego will have a 1.1 MW solar array on its roof is one more example of the solar potential that just waits to be tapped on commercial buildings. Using SunPower’s T10 Solar Roof Tiles, the system is estimated to offset more than one million pounds of carbon dioxide per year—an amount roughly equivalent to planting 150 trees annually. In total, about 200,000 square feet of roof space (distributed over five separate buildings) will be covered with the 180-190w tiles. The project is expected to provide about 10% of the facility’s power demand.
