The test, a joint project of NIST, the U.S. National Park Service and the Tennessee Valley Authoriy, uses pho- tovoltaic (PV) cells, semiconductors that convert sunlight into electr

The test system has an array of PV cells, a water storage tank that in- corporates multiple electrical resistive elements, and a controller that maxi- mizes the conversion of solar energy into heated water. Unlike thermal devices, the PV de- sign avoids many of the problems in- herent
18、 in traditional thermal systems. For example, therere no pipes through the roof, fluids that can freeze or stor- age batteries to provide energy during the night or cloudy days. The cost of a PV system is much higher than a solar system (about $4,000) but that cost is expected to fall in the next de
19、cade as the cost of PV cells decline from about $5 per peak watt to about $1.50. The park PV system is a refined version of systems being tested at NIST s headquarters in Gaithersburg and at the Florida Solar Energy Center in Cocoa, Fla.
