Streszczenie: Latvia is the country located on the 57th north latitude having rather low average solar radiation. Therefore stationary placed ordinary flat plate solar collectors are not effective enough for the use in Latvia. Solar collectors of special constructions like tracking the sun, concentrating the radiation and others are more complicated by their construction and are therefore quite expensive. More perspective in the meteorological conditions of Latvia and other northern countries could be solar collectors with absorber of semi-spherical form. Such collectors are able to absorb the solar radiation from its entire surface and do not contain moving parts. The results of our calculations have shown that at clear and 2 sunny summer day the semi-spherical collector with base area of 1 m receives 1.3 times more heat energy than a flat plate collector, positioned at optimal (approx. 40o) inclination, and 1.5 times more heat energy than flat plate horizontally placed solar collector.
Słowa kluczowe: semi-spherical solar collector, solar radiation, effective area, efficiency
