Theoretical calculations As it was noticed, only a part of solar insolation on the surface of a collector is transferred into heat. The amount of this energy depends on the type of the solar collector and meteorological conditions of the place, where the collector is working.
Only a part of solar radiation striking the solar collector is converted into heat energy. The value and the intensity of solar insolation over a year, strongly depend on the latitude and weather conditions of the place. The heat energy produced by a solar collector depends on the type and design of the collector.
The maximal power of solar insolation on the collector Pmax = Cs (cosδ*cosφ*cosω + sinδ*sinφ), where Cs – solar constant (Cs = 1355 W m-2.); φ – latitude angle of the place (for Latvia φ = 57 ̊); ω – angle of solar hours (in the middle of a day ω = 0); δ – declination angle of the sun, degree. n – number of the year day counted from January 1. 2.
The study aims at providing the thermal elements for the specification of networks of solar collectors. The study found that the number of solar collectors or heat transfer surface area required to achieve the targets depends on the ambient conditions chosen for the design.
The performance of the solar collector is influenced by the type of reflector and receiver being selected, and its material also has significant impact. The choice of the heat transferring medium, storage material, receiver design and its performance parameter also influences the solar collector’s performance.
