The Contemporary Newnan Solar Energy System was designed by Contemporary Systems, Incorporated, Jaffrey, New Hampshire, to provide 60 percent of the space heating and domestic hot water (DHW) for a two story residence located in Newnan, Georgia. The system consists of fourteen Contemporary System Series V warm air collectors (392 square feet), 328 cubic foot rock bin thermal storage containing 1 to 1 1/2 inch diameter stones, an air handler, heat exchangers, an 80-gallon DHW preheat tank, controls, associated plumbing and air ducting. Auxiliary heating is provided by an electric heat pump supplemented by electric resistance heaters when outdoor temperatures drop below 15 degrees fahrenheit. A 40-gallon electric hot water tank is supplied water through the 80-gallon preheat tank. The system has six modes of operation.
