Study on the Method of Increasing PV Efficiency for Power Supply at Space Stations

The power supply of space stations and satellites is carried out through using double-sided photovoltaic panels with efficiency 25% to 30%. It is known that a solar power plant has significant weight characteristics (45 kg to 50 kg per 1 kW). The cost of delivering 1 kg of payload to the space station is 20000$ to 22000$. In this regard, reducing the weight of a solar power plant designed to supply space stations has a significant demand and can be implemented by increasing the power efficiency of photovoltaic panels (PV). The purpose of article is to study a method for improving the electrical power efficiency of photovoltaic panels for the power supply of space stations. In this study was used, the main electrical power regularities in the field of solar power and statistical data processing methods. In the result of the study, were obtained the dependences of the production of photovoltaic panels on solar radiation. In addition, it has been determined the parameters for assessing the operating modes of a solar power plant and the effect of introducing the proposed method on the technical and economic parameters of the facility.
