INTRODUCTION For evaluation and comparison of solar collectors, many factors need to be considered: collector thermal performance and costs, lifetime of the collectors and decrease of collector performance due to aging. The thermal performance of a solar collector is fairly easy to assess.

From 2002 to 2007 the thermal performance of solar collector has been increased by 29%, 39%, 55% and 80% for a mean solar collector fluid temperature of 40 ̊C, 60°C, 80°C and 100°C respectively. The increase of thermal performance is more significant for an increased solar collector fluid temperature.
Their study’s scope was analysing economic, operational and environmental factors for designing the solar collector. Their results showed that the energy contribution of this thermal system could cover approximately 40–80% of the required energy in the industries.
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.
