Reducing the effect of dust deposition on the generating ...
Jul 15, 2018· There is a nearlinear relationship between the sand covering rate and power generating efficiency of the PV module (Jiang et al., 2011), expressed as follows: (4) E 1 / E 2 = K · ρ where E 1 is the output power after sand covering, E 2 is the output power before sand covering, K is the filling factor and ρ is the sand covering rate.
