Analysing the feasibility of using solar energy in an on-grid system

Generating electricity from solar energy can be used even during periods of lower solar radiation. In this way as well as being a renewable source and reducing or zeroing out the local utility's energy consumption it also helps to reduce costs and allows the return on investment to happen long before the useful life of the photovoltaic system ends. Therefore this work consists of a case study of photovoltaic electricity generation in a model home in the city of Iúna - ES showing that despite the variables imposed by nature and the fact that it is an expensive source to install it is still viable to convert solar energy into electricity.
