Solarcell output efficiency3/6/2023 A detailed economic analysis was then carried out including relative maintenance costs. This study also examined the effects of ambient air temperature and wind speed close to the panels which in this locale had very little impact on conversion efficiency. These conversion efficiencies are lower than expected but are in part due to local conditions and their significant impact on movements in the maximum power point, which was not tracked in these fixed load experiments. The uncertainties shown represent the standard deviation in the conversion efficiencies determined over the 12 month period of the study. a/m 2 and 820.6 kW.year/m 2 respectively.The results show that for a fixed orientation the monocrystalline, polycrystalline and amorphous panels, had average conversion efficiencies of 6.8%☒.4%, 5.7%☒.0% and 4.2%☑.5% respectively in terms of total incident solar energies on the plane of cells which were 809.4 kW Overall performance of the solar cell panels is given via both annual output and an average conversion efficiency over one whole year. The fixed panel rig was positioned at a tilt angle of 30°, facing south. This study was conducted at Nakhon Ratchasima Rajabhat University, Thailand. Monocrystalline, polycrystalline and amorphous silicon solar cell panels were installed side-by-side on the same fixed rig to determine the relative performance in a tropical location.
