Photovoltaic solar modules for autonomous heat and power supply

Abstract

Abstract The article presents solar modules of various types and designs, in the development and study of which the author took part. Along with planar photovoltaic solar modules with an extended term of nominal power, high-voltage matrix solar modules with an extended term of nominal power and electrical efficiency up to 28% are considered. Such modules are made with the help of encapsulation technology with a polysiloxane compound, which improves the performance of solar modules and increases their service life. For autonomous power supply of mobile and compact electrical devices in the field, folding and sectional solar modules are proposed, which, when parallel-sequential switching, allow to gain the necessary power. For architectural solutions, solar roofing panels are presented, which along with electrogeneration make it possible to generate heat energy, and the base can be made of recycled plastic, which has a positive effect on the environment. To reduce the number of solar cells used, a concentrating solar roofing panel has been proposed, which allows the use of thermal energy. For the cogeneration of electric energy and thermal energy, a concentrator solar photovoltaic thermal module with a paraboloid type concentrator is also proposed. Each type of solar modules is used in a stationary heat and electric power supply and mobile power generation.
