Smart meters are currently replacing conventional electricity meters. This enables the calculation of the profitability of a solar system with electricity storage according to a customer's individual behavior and his climatic circumstances. This book shows how to implement a thorough time series based savings calculation in Excel. On the one hand physical and technical factors are taken into account (i.e. component efficiency), on the other hand a thorough non-standard statistical model is developed. This model corrects the effects of 15 min interval based smart meter resolution. The validity ...
Smart meters are currently replacing conventional electricity meters. This enables the calculation of the profitability of a solar system with electricity storage according to a customer's individual behavior and his climatic circumstances. This book shows how to implement a thorough time series based savings calculation in Excel. On the one hand physical and technical factors are taken into account (i.e. component efficiency), on the other hand a thorough non-standard statistical model is developed. This model corrects the effects of 15 min interval based smart meter resolution. The validity of the model is proven by applying existing time-series of load and solar power and comparing the results to a reference model.
