Investigations of four different evacuated tubular solar
collectors produced by different Chinese manufacturers have been
carried out. Tests of a small solar heating system for domestic
hot water supply with the four different collectors have been
carried out. By means of the tests the efficiency of the
collectors have been determined. The incidence angle modifier have
also been determined by means of the tests. The yearly thermal
performance of different solar heating systems have been
calculated both with the Chinese evacuated tubular solar
collectors and with normal flat plate collectors for Danish
conditions. By means of the investigations the suitability of the
evacuated tubular solar collectors are evaluated.
