Typical Floor Design
This parabolic solar concentrator dish collects about 3 square meters of sunlight. At 100% efficiency it should produce about 3000 watts of power or 10242 BTU per hour. In actuality it produces about 1873 watts or 6391 BTU per hour. This is a system efficiency of about 62%.Experiment date 9/25/07Ambient temp 65˚F 83 pounds of water(This is about 10 gallons at 8.33 pounds per gallon.)1 BTU raises 1 pound of water 1˚F 77˚F change of 83 pounds of water = 6391 BTUBTU / hour to Watts = BTU / hour x 0.293Watt-hours to BTU = Watts x 3.4141873 actual watts / 3000 potential watts = 62.4% efficiency
1873 watts of solar thermonuclear radiation was being collected at the focal point by the collector coil.
