Electric motors replaced diesel engines at Heidel Hollow, on Wednesday, April 20, 2011. A family owned farm since 1852 is a 1,800 acre operation in Germansville, PA. Led by David Fink, President of Heidel Hollow Farms, they mainly produce and compact hay for export and grow produce on 300 acres for local sale. With the financial help of the U.S. Department of Agriculture (USDA) an 896 panel solar array was recently installed on non farmable diversion ditches. Rated at 200 kilowatts, they project 240 megawatts of electricity to be produced each year, providing up to 70% of the farms electrical needs. Additionally, USDA financial assistance made it possible to replace the hay compactor’s diesel engines with clean low-maintenance, low operating cost electric motors to power the compactor's hydraulic system. The compactor increases the density of baled hay by two and half times for more efficient shipping to overseas customers. USDA Photo by Lance Cheung.
