CONSTRUCTIVE FACTORS DEFINING RELIABILITY OF THE ENERGY SUPPLY SYSTEM
One possible way to use the energy of the sun is to convert it into thermal energy with the help of solar collector systems. Efficiency and reliability of operation of power supply systems with solar collectors depends on the choice of the structural elements of the converter. The operational proper...
