Using a DC Submersible Pump in a Domestic DC submersible pumps are a new technology, developed especially for solar power. In an alternative energy home, a low-powered DC pump can be more efficient and economical to use than a conventional 120 or 240 vac well pump. DC submersible diaphragm pumps can lift water from wells as deep as 300 feet. They pump slowly, between 13 and 4 gallons per minute. Even such a low volume is enough water for a family's daily use if the pump runs a few hours per day...

Twelve 51 Watt Kyocera PV Modules 9 Amperes at 24 to 32 VDC Twelve 51 Watt Kyocera PV Modules 9 Amperes at 24 to 32 VDC than a Sun Frost. Four Osram compact fluorescents supply the lighting. My Sun Frost is a little unique in that I bought it without a finish and built an oak cabinet around it to resemble an antique ice box. The oak came as used flooring from an old house. The Sun Frost has operated very well for over two years and I couldn't be more pleased. The automatic washer is a Whirlpool...

In bright constant sunlight, if you measure the current that a panel puts out as a function of panel voltage, you'll get a graph which looks like a . At the knee of the curve is the maximum power point the point at which current times voltage is a maximum. In dim light, the same panel might give a curve which looks like b . Notice this curve has much less power, but the voltage of the maximum power point doesn't decrease very much. Vpmax will decrease with decreasing sunlight and increasing...

When my neighbor Danny Cunningham return building a medical clinic in Xuan Hiep, Vietnam in spring 1992, all he could talk about was going back. Danny had gone as a Team IV member of the Veterans Vietnam Restoration Project VVRP , and soon talked me into returning with him. I have been designing solar powered water syste and water filters with the architect Michael Reynol and Solar Survival Architecture. So I suggested that we get pumps and filter Vietnamese water. Danny got in touch with Mr....

I enjoyed your article on phantom loads HP 37 . I, too, have never understood why a clock has to come with every appliance. And I can't stand the idea of unseen, unknown electronic creatures gobbling up electrical power at my expense My question is this, can turning off and on the power supply to some appliances damage them I am concerned primarily with satellite equipment. As you know, this equipment is expensive, and my serviceman says that he has experienced problems if the equipment is shut...
