INVESTIGATIONS OF CONSTRUCTIVE AND ENERGETIC PARAMETERS OF SOLAR RADIATION RECEIVERS WITH CONCENTRATORS

In this paper some new photovoltaic modules, including trapeziform with mounted photoсells receiver and half-parabolocylindrical concentrator, to ensure efficient conversion of solar energy into heat and  electricity, was investigation. The mathematical modeling to creation a computational algorithm design thermo-photoelectrical module the specified power parameters using laws of geometrical optics, as well as heat and mass transfer. When using such modules, in which basis is half-parabolocylindrical concentrator and photocell system with coolant flow can create cogeneration plants to generate electricity and heat. Developed by this method of model samples are examined for appropriate stands and tested in field conditions. The heat and electrical parameters become defined according to the calculation results to within 10%.  The solar module with half-parabolocylindrical concentrator, trapeziform concentrated radiation receiver with mounted photoсells and coolant flow system delivers maximum output 254 W at 43 °C, 219 W at 74 °С and 236 W at 58 °С. Concentrating solar radiation to 50, uniformly of  insolation 0.25.  The solar module with half-parabolocylindrical concentrator, trapeziform concentrated radiation receiver with mounted matrix high-photovoltaic сells and coolant flow system was investigated also. Coefficients of occupy volt-amperes characteristic was m = 0,728 and 0,660 for concentrate and non concentrate solar stream correspondingly.
