The relationship between the weather and the incidental solar radiation onto the solar cell in amphoe thanyaburi area

Abstract

One important factor that makes the variations of electric current produced from solar cells (Ipv) is the variability of the weather conditions of the day. The one year experiment from January to December, 2012 had been set up. The experiment of the comparison of the weather data, satellite images, and the different current (Ipv_d) was obtained from daily Ipv. The results illustrated that there were 4 major types of the relationship between the Ipv_d and weather conditions; 1) Low Ipv_d at around 2,000 mA with low perturbations would correspond to the clear sky condition. 2) Perturbation of Ipv_d in some periods would correspond to the cloudy condition. 3) High perturbations of Ipv_d for all day long would relate to the rainy – cloudy condition. 4) High Ipv_d at around 4,000 mA with low perturbations would relate to the cloudy condition all day long.
