Today, there are several types of photovoltaic cells on the commercial market, and
their efficiency in natural conditions varies depending on climatic factors. Taking into account that
the weather conditions of different regions are different, there is a problem of determining the
efficiency of different types of photoelectric batteries for a certain region and choosing a type with
stable parameters.
To solve this problem, different types of photoelectric batteries (PV) of the same capacity are
installed in a portable photovoltaic device (MPHD) and tested simultaneously under natural
conditions. Scientific research was carried out using PVs MPHD mounted on a two-axle trailer.
MPHD is 1300x800 mm in size, designed for loads up to 700 kg. The power of each PV installed on
it was 50W: the front glass, the back protective film in the form of a texture was transferred to white
and black monocrystalline, flat glass monocrystalline and polycrystalline photoelectric batteries. According to the results of the research, different types of photoelectric and photothermal
batteries with the same capacity were tested in natural conditions using MPHD, and the changes in
their electrical parameters were analyzed. In addition, the FEB type with a stable parameter was
determined in the study.
Using the developed MPHD, by testing different types of PV in different regions of the republic,
it was possible to determine the type of FEB with stable parameters suitable for the region. Therefore,
it is possible to recommend the type of FEB intended for use in planned photoelectric station (PVS).
The use of a photoelectric battery, correctly selected taking into account the climatic conditions of
the region, provides an opportunity to reduce energy losses in PVS.
