摘要: Abstract The effect of dirt on the transmittance solar radiation through various inclined glass plates and plastic films, which are used as a transparent cover for flat-plate collectors, has been studied. correction factor plate at an angle 45 deg from horizontal is 0·92, significantly different value 0·99 given by Hottel Woertz[1]. greater film than it any inclination.
