DETERMINATION OF OPTIMAL SLOPE ANGLE FOR SOLAR COLLECTOR IN DEPENDENCE ON DURATION OF SOLAR PLANT FUNCTIONING

The issue of slope angle choice for solar collector on the example of Ukraine south is considered. An optimization criterion is a maximum of passed heat amount to the consumer depending on duration of exploitation of the solar plant during a year. On the basis of insulation on a horizontal surface in a cloudless day the calculations of the solar energy amount on the collector sloping surface during a warm half and throughout the year depending on the slope angle are conducted. Taking into consideration the real cloudiness, losses of heat in a collector and at the transport of coolant from a collector to the consumer the calculation of the passed amount of heat is conducted. As a result of variant calculations the optimal slope angles for solar collector for duration of solar plant functioning during a warm half and throughout the year are obtained.
