Electric fence chargers are a natural use for photovoltaic power, since they operate on low-voltage DC power and are often located quite a distance from available electricity. Energy Sciences markets both 6- and 12-volt PV versions of the Parmak fence charger. Both versions are battery-equipped-to get through cloudy periods-and carry two-year warranties. Priced at $169.95 and $299.00, respectively.

MAJOR APPLICATIONS

SunAmp Systems specializes in putting together integrated applications of solar power. Some of its standard setups include Electric Boat Kits for trolling motors, including panels, mounting brackets, regulator, batteries, and wiring (from $559 to $1009 with Mobil or Kyocera panels); SunLight Solar Yardlight, which hangs on a pole and switches on automatically ($495); and a Swimming Pool Kit, which replaces a 1.5 HP AC motor/pump system ($9450). Also available are custom DC evaporative cooling systems and solar-powered water pumps.

FOR SUN FANS

Fan operation provides a perfect application for photovoltaics, since the timing and power of the circulator will be proportional to the solar intensity—and therefore heat. Solar Electric Engineering has three such systems, shown above, ranging in price from $100 to $500. The modular unit is especially intended for RVs and fits in the standardsize hatch cover. The two different-sized fans are intended for gable applications, ventilating attics, greenhouses, etc.

Solar Electric Engineering has a tantalizing prospect: Look for its PV-powered satellite television dish ($1,500 with panel), which is expected to hit the market soon.
