Journal Title: Вестник Харьковского национального автомобильно-дорожного университета - Year 2018, Vol 80, Issue
Abstract
Currently, the most commonly used method is the socalled direct method of converting solar radiation into electric current using a variety of solar batteries (SB). The most widely used in the application were silicon SB. Consequently, the question arises as to which optimal parameters should have an elec-trical load in order to ensure the efficient operation of SB. Goal. Determination of the optimal active load parameter for monocrystalline and polycrystal-line SB, which meets the criterion for transmitting maximum power to load. Methodology. The analyti-cal methods of research on the development and application of methods and devices for transforming the energy of the sun into electricity were used. Ex-perimental methods of research and mathematical methods of processing experimental research were used. Results. The analysis of existing types of sili-con SB is carried out, their classification is present-ed. The determination of the optimal active load parameter for monocrystalline and polycrystalline SB is carried out, which corresponds to the criterion of transfer of maximum power to load. The results of experimental studies are presented as volt-ampere characteristics and the dependence of the power of SB on the load current. An analysis of the results of experimental studies showed that for the most effi-cient operation of the SB, its active load should be maintained in the range from 3 ohms to 3,5 ohms. Originality. The method for determining the optimal electrical load parameters for silicon monocrystal and polycrystalline SB has been improved. The method of correlation of electric loading of SB to their own active resistance is presented. Practical value. The obtained results allow us to determine the optimal electrical load parameters for silicon mono-crystalline and polycrystalline SB. If the types of SB in question are compiled into systems with a corre-sponding serial-parallel connection, then it is nec-essary to determine the internal resistance of such a system. Applying this principle, you can determine the optimal load parameters for any silicon solar system.
