Effect of dust on flat plate collectors

摘要: This paper deals with the effect of dust on performance flat plate collector. Six collectors forming three pairs were tested. The first pair was placed at 60°, second 30° and third zero degree to horizontal. In each group one collector wiped daily while other left unwiped. amount absorbed solar energy by computed compared results others. damaging also studied a storm strength which this will take place deduced. A 32, two inches diameter, cell array covered 3 mm fiber glass cover tested no then for 72 hours under normal conditions without wiping top surface current characteristics plotted versus time day. quantity settling per day square meter measured number days high storms in various parts Saudi Arabia shown plot. It can be deduced that has predominant energy. reduces its intensity Arabia.
