SunWatt Corp.

Development of Photovoltaic/Hot Water Hybrid modules, starting in 1978. Built a number of experimental prototypes (see INTERSOL 85 paper), then offered two models for sale: The SunWatt H100, which was 36" x 78" by 8" deep and had 100 watts of electrical output and a thermal output of 1000 watts at AM1 conditions; and the SunWatt H150, which was 48" x 96" x 8" deep and had 150 watts of electrical output and 1500 watts of thermal output. These PVT modules used Winston type CPC concentrators at 1.9 to 1 concentration ratio, so that no tracking or seasonable adjustment was needed. Some development work on PV/Hot air hybrids, but no real careful experimental measurements performed.

Ongoing work on the photovoltaic still, started in 1994. (See SOLAR 2000 paper) This device uses evaporating sea water to cool the PV cells, and uses the 2 to 1 CPC reflectors as the condenser elements to produce distilled water and electricity at the same time. The third prototype, built at the Universidad Nacional de Ingeniería in Managua, Nicaragua, produces 1.5 litres of distilled water per day, as well as serving as a 22 watt PV module for the 0.374 sq meter device aperture. The next prototype, now being built, will incorporate heat exchanger tubes in the CPC reflectors to preheat the incoming sea water and cool the reflectors to increase the effiency of the distillation. While this will raise the PV cell temperature somewhat, the temperature should not exceed the 60ºC design temperature, desired to not interfere with the battery charging function of the system.
