news:xh05e.4996$VF5.1702@edtnps89: Will this 500 watt panel array ever actually put out 500watts? Another interesting point is that a solar cell is very poor efficiency. Here's a report on a new Sanyo HIT cell hitting 21.3%.... "The resulting efficiency level exceeds 21.3 percent, which until now, was the highest level delivered by SANYO HIT solar cells. The HIT solar cell is 10cm square, nearly the same size as solar cells currently used for home and industrial applications." Regular silicon solar cells are like 6% efficient! Even if we get this supercell technology, to get 500 watts out, we're going to have to put 2500 watts of sunshine in and cool the cells of 2000 watts of heat! Will that be fresh water or seawater cooling??...(c; Maybe we can use the heat to cook lunch on the metal heat sinks...saving the drain from the microwave oven! Wonder why we can't run a little water pump in the loop to the water heater? The waste heat from the solar charging could give us all HOT SHOWERS AND DISHWATER! The big panel on Lionheart puts out 5A on its best day and only if the boom is out wide and not shading anything on top of the cockpit hardtop it covers.... |
