INVESTIGATIONS THE OPTICAL-POWER PARAMETERS OF THE SOLAR MODULES IN AN ASYMMETRICAL PARABOLIC-CYLINDRICAL CONCENTRATOR, WITH PHOTODETECTOR AND SECONDARY REFLECTOR WITH TRACKING SYSTEM

The paper discusses the new photovoltaic modules, which include photodetectors and hubs and provide efficient conversion of solar energy into heat and electricity. The mathematical modeling to create a design algorithm for calculating thermal solar module with the specified energy parameters and using the laws of geometric optics, as well as heat and mass transfer. Mathematical models for calculating the optical parameters of the solar energy module ruled photodetector and secondary reflectors asymmetric parabolic-cylindrical concentrator. Showing calculated according to the following: the concentration distribution of light on the surface of the detector of the line on the width of the focal region; angle of total reflection of the secondary reflectors concentrated radiation from the parametric angle γ; the geometric dimensions of the upper and  lower reflectors from the parametric angle γ; coordinate location (profile) of the secondary reflector relative to the photodetector. Profile module (on the basis of which patterns are drawn in Avtocad for manufacturing the hub unit and as a whole); the longitudinal shading photodetector depending ΔL time interval  tp idle engine tracking system, the number of intervals (engine running) per unit time  k  by the angle of deviation (parametric angle  γ) of the incident solar radiation on the midsection hub, depending on engine power consumption tracking system. The use of such modules is based parabolic-cylindrical concentrator and a photodetector with a coolant flow system allows the creation of co-generation plants to generate electricity and heat. Prototypes were developed by this method being explored at the respective stands and tested in field conditions.
