ABSTRACT

Financial and technical feasibility of a photovoltaic (pv) power system has materialized into a commercial market in some specific regions and within specific applications. The sizing problem due to poor reliability is related to how design engineers understand the energy output from the installed pv module, and not to oversize in order to the optimize cost and not to undersize in order to optimize reliability. A single-crystal pv module was tested at the Energy Technology Energy Park, Asian Institute of Technology (AIT), from 8 June 1988 to 4 July 1988. On the basis of the data gathered, the irradiance and the module temperature explain a high percentage of variation in all response variables of the module. The current and power of the module are sensitive to the irradiance level, while the voltage and efficiency are sensitive to the module temperature.
