Solar energy refers to clean and renewable energy sources. The operation of radiation heating systems does not require significant costs. The work of radiation panels is affected by a number of natural factors, such as сlouds, temperature and humidity of atmospheric air, precipitation, fog, time of year and day, Sun position angles and installation angles of solar panels. With an insolation area of a solar collector of 0.02 m², it is capable to produce about 1 ... 2 W (50 ... 100 W/ m²) in winter and 5 ... 8 W (250 ... 400 W/ m²) in summer. With a living area of a small farmhouse of 60 m², the area of the southern slope of the roof is 50 ... 70 m², which makes it possible to get 2.5 ... 7 kW of power for premises heating. With traditional thermal insulation, such power is enough for heating in light frost (up to –20 °C), with stronger frosts, additional electric, stove or boiler heating is necessary.
