Abstrakt: The paper considers experimental results on the development of an effective photothermal battery (PTB) based on photovoltaic batteries (PVBs) made of monocrystalline silicon with a thermal collector (TC) made of cellular polycarbonate for a mobile autonomous photovoltaic installation of water lifting (APVIWL) from wells in an extreme dry climate (taking into account high temperature, pollution levels, and the density of incident solar radiation on the surface of the PVB in comparison with standard testing conditions). We showed that PTBs work more efficiently than standard design PVBs. All PTB parameters (no-load voltage, short-circuit current, and electrical power) under the conditions of switching on the side reflectors are greater than the values of the parameters of the standard design PVBs obtained under standard testing conditions. The dependences of PTB efficiency on the temperature and solar radiation intensity (SRI) in February, at ambient temperatures of 4–9°С, were investigated. The PTBs in the conditions of photothermal mode of operation provides the optimal mode of operation (constant voltage and battery charging current) of a mobile APVIWL energy storage system, which allows them to be used in extreme dry climatic conditions of rural regions of Uzbekistan for lifting water and, if necessary, for household needs outside the irrigation season.
