Detection of the corresponding time between the photovoltaic current difference and the surface temperature dropdown by using solar cell
MetadataShow full item record
During the daytime, solar cells can be used in terms of meteorology because the variations of the current obtained from solar cells are associated with changes in daily climate. The case study of the comparison between the surface temperature and the different current (Ipv_d) obtained from the solar cells in the periods of November 2011 to February 2012 which known as the winter period of Thailand had been conducted. The result showed that it was possible to observe the decreased surface temperature at the time that the increased Ipv_d was more than 6,000 mA. Vice versa, the decreased surface temperature would not be observed when the Ipv_d was below 6,000 mA. The decreased surface temperature may reflect the influence of the traveling high pressure area moving to cover and collide with the steady-low pressure area at the study area. The result of the collision caused extensive cloud cover resulting in increasing Ipv_d.
