Predicting the power production of solar photovoltaic (PV) panels is necessary for successful commissioning and operation of PV power systems. Lifetime estimations are required to analyze commercial viability of the planned PV system, whereas hourly and daily production estimations are important considering operation in the electricity market. Here, a specific setup, consisting of vertically mounted bifacial solar panels in a high-latitude location, is monitored. Measured power production is compared to modelled productions achieved by several simple modelling approaches. The aim is to analyze how specific and high-quality data is actually needed to model accurately the total energy production in several temporal scales, ranging from one-minute to multi-year. The results help to understand the required complicity for pre-installation production estimations and thus contribute to increasing bankability of vertical bifacial PV systems.
