The efficiency of a solar collector depends on its ability to turn sunlight into usable heat. The kind of collector, the quality of its materials, and its design, like special coatings and airtight seals, play big roles.

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.
The investigation was carried out on collectors used for a period of 10 years or more. It is expected that the estimated service life for the coating is of the order of 30-40 years in an airtight solar collector with controlled ventilation of air, while in a non-airtight collector, the estimated service life is shortened to 5-10 years.
These parameters are electrical power output, thermal efficiency, total aperture area of the solar collectors, number of the solar collector rows, thermal energy, and mass flow rate of the synthetic oil (HTF) in the solar collectors. 2. System descriptions In this study, two systems are considered.
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 amount of this energy depends on the type of the solar collector and meteorological conditions of the place, where the collector is working. The average amount of heat energy produced by a flat plate solar collector during a day has been calculated by formula K – parameter, ̊C.
