EarthNet Energy. Because not all rooftops are suitable for solar collector placement, the company offers a Ground Mount Pedestal mounting system adaptable to most types of flat-panel and evacuated-tube solar collectors. The heavy duty, powder-coated-steel pedestals are available in 5-foot-tall bolt-mount or 7-foot-tall direct-burial models. The company also manufactures complete evacuated-tube and flat-panel solar collector systems. 717.414.7652. www.earthnetenergy.net.
