Impact of a large-scale market integration on the orientation of photovoltaic modules

To increase the amount of renewable energies, the Renewable Energies Act (REA) in Germany guarantees a fixed feed-in tariff for 20 years for every kilowatt-hour that is produced. Thus, photovoltaic modules were faced in the direction of the highest energy production. In this paper we investigate, if in a future energy system with a high share of renewable energy power and especially PV power, there is an incentive to face modules divergent because of an overproduction during noon. Hence, we modelled the PV generation for the states in Germany in detail as well as the spot market for the years 2014 and 2035 according to the Grid Development Plan of the German Transmission System Operators (TSO).
