Abstract
The present technology of the photovoltaic is still highly costing and the efficiency can improve to maximize efficiency, so the investor need to collect and study the return of project. In general the photovoltaic module has life time about 25 years and the almost of Photovoltaic Power Plant costing modules about 70% of portion. Hence, the degradation of photovoltaic module has an effect to the energy yield and benefit of project. The return of the project also depend on many factors such as the temperature, moisture content, the damaged of modules, government subsidy, CDM benefit and etc.
This paper is considered the effecting about the degradation of 2.16MW amorphous photovoltaic power plant that the energy yield output is directly affect the capital and cost of project. The return of the investment when the solar module was degrade of the efficiency 10%, 20%, 30% by using NPV, BCR, IRR and PB to find out though the breakeven point of project and the degradation percentage that unacceptable to investment. This paper output applicability to determine to others amorphous photovoltaic power plant project by adjustment some information and factors appropriate to each project site.
