RELIABILITY ASSESSMENT OF ROOF TOP SOLAR / PV SYSTEM

Oday’s world needed uninterrupted qualitative electrical power with high reliability. Electrical energy that is derived from fossil fuels produces high pollution one side and on the other side electrical energy demand is co ntinuously increasing . To tackle this typical twin p roblem alternative resources such as wind, solar and bio mass energy sources are to be preferred. In order to reduce the utilization of fossil fuels that is to save the fossil fuel reserves {coal , diesel e.t.c} it is very essential to see towards the above mention ed alternative sources. Solar/PV systems are one of the most promising methods of electrical power generation. PV - grid connected systems are worldwide installed because it allows consumer to reduce energy consumption from the electricity grid an d to feed the additional energy back into the grid. A realistic cost benefit analysis requires evaluation models that can recognize the highly erratic natur e of solar energy source and it’ s interdependence of random variables inherent in them . T he proba bilistic reliability evaluation of solar photo voltaic syst ems is required for gaining a better insight in component sizes and location needed before they are built . P roper survey of solar radiation sources study may be carried over . In this paper a cas e study of a roof top solar power plant ( 100 KW) at “Vidyut soudha, Somajiguda, Hyderabad , Telangana ” is considered for reliability assessment. The reliability evaluation of solar PV energy system is promising technologies to justify their views in small scale grid assistant/standalone applications for rural or remote areas
