CALCULATION OF ENERGY PRODUCED BY SOLAR COLLECTORS

Only a part of solar radiation striking the solar collector is converted into heat energy. The value and the intensity of solar insolation over a year, strongly depend on the latitude and weather conditions of the place. The heat energy produced by a solar collector depends on the type and design of the collector. Several types of solar collectors both theoretically and experimentally have been investigated and formulae for the calculation of their efficiency and heat energy produced by the collector have been developed. By the use of the computer program MS Excel the amount of the produced heat energy for a flat plate solar collector with one glass cover, two glass covers and selective tracking the sun solar collector has been calculated and the results presented.
