    Abstract

    In the last decade, there has been a dramatic increase in the numbers of photovoltaic (PV) Systems as the world shifts toward clean and sustainable energy resources. Seeing this rise in the Solar PV market, multiple new manufacturers are seeking entry into the marketplace and the need to identify the good performance modules from the bad becomes an absolute necessity. The Performance and reliable operation of PV Modules depend on many factors including materials, manufacturing processes and environmental constraints.  Even  best  quality  PV  modules  and  systems degrade with time. The degradation rate largely depends on field conditions and manufacturers, as well as test engineers are highly interested in accurate performance modeling of the field installed PV modules. Thus two factors have been seen to give  good  indications of  the  degradation: the  Performance Ratio and the Performance Index. As a power plant in Pakistan is analyzed for its degradation using these two factors in this paper, an indication on its possible lifetime can be predicted. The  performance  ratio  method  indicated  at  degradation of 0.61% while the performance index method indicated a degradation of 1.09%.
