The present research examined the study of the laboratory the effects of dew formation and humidity on the parameters mono crystalline and polycrystalline silicon solar panel. To create statuses dew formation equipped test lab device performance solar panel systems to environmental monitoring temperature and relative humidity. were evaluated this study dew formation of air relative humidity of 45, 60 and 75 percent at 25 degrees Celsius temperature on the surface the panel. The results showed that dew formation on the surface of the solar panel increases the performance parameters relative to humid weather conditions. The effects of the type of silicon panel and the relative humidity of ambient were very significant (p <0.01) on almost all functional parameters of the solar panel. By increasing the amount of dew covering on the panel surface, the functional parameters decreased linearly. The effect of temperature on the performance parameters was much higher than the air humidity. In general, the efficiency of a mono-Si solar panel in the conditions of relative humidity in the range of 45% to 75% resulted in 13.74% to 8.43% for mono-Si panel and 11.38% to 8.1% percent for a poly-Si, respectively.
