Calculation of the energy provided by a PV generator. Comparative study: Conventional methods vs. artificial neural networks

摘要: Abstract The use of photovoltaics for electricity generation purposes has recorded one the largest increases in field renewable energies. energy production a grid-connected PV system depends on various factors. In wide sense, it is considered that annual provided by generator directly proportional to radiation incident plane and installed nominal power. However, range factors influencing expected outcome reducing energy. aim this study compare results four different methods estimating produced generator: three them are classical fourth based an artificial neural network developed R&D Group Solar Automatic Energy at University Jaen. obtained shown method provides better than alternative study, mainly due fact takes also into account some second order effects, such as low irradiance, angular spectral effects.
