Abstract

Owing to the fact that input data for existing PV forecast algorithms are hard to come by, there is the need to develop a method based on data that is relatively easy to obtain and one with a much simpler algorithm which still produces acceptable results. This paper proposes a method for photovoltaic output backcast and forecast using cloud cover and historical data. The method is about five times more efficient than the benchmark model.
