Solar Collector Impact Resistance
Standard Practice for Determining Resistance of Solar …
effect of falling hail upon solar collector covers. This practice may be used to determine the ability of ßat-plate solar collector covers to withstand the impact forces of hailstones. In this practice, the ability of a solar collector cover plate to withstand hail impact is related to its tested ability to withstand impact from ice balls.
Hail resistance of solar collectors with tempered glass covers
The resistance of solar collectors glazed with 3 mm of tempered glass to hailstones of up to 10 cm in diameter and 0.5 kg in weight which fell on Fort Collins, Colorado is discussed. Of the ten solar heating systems directly in the hailpath with tempered glass covers, seven were undamaged, two lost one collector panel each, and a 700-panel collector had …
