Abstract

This research presents the annual energy yield and economic evaluation of a new prototype of evacuated tube collector (ETC) with applied anodized aluminium sheet as solar absorber. The size of ETC was 15 vacuum tubes with 1.08 m2 solar absorber area. The maximum thermal efficiency (hmax) of ETC was 0.72. As the results, annual energy yield of ETC per a unit area of solar absorber was 1,117.9 kWh/m2 or 1,207.3 kWh (4,346.4 MJ) for the prototype ETC (1.08 m2 solar absorber area). According to the Life Cycle Cost (LCC) evaluation, LCC of this prototype ETC was 22,993 Baht which is lower than commercial solar collector. Therefore, the evacuated tube collector (ETC) with applied anodized aluminium sheet as the solar absorber can be competitive with commercial solar collector, and it is high potential for producing the hot water in household and industrial sectors that required hot water in manufacturing.
