Abstract Currently, most PV (photovoltaic) modules are aligned in a way that maximizes annual yields. With an increasing number of PV installations, this leads to significant power peaks and could threaten energy policy objectives. Apparently sub-optimal inclinations and azimuth angles of PV plants on building roofs could counteract such tendencies by achieving significant temporal shifts in the electricity production. This paper addresses the potential of these counter-measures by evaluating the optimal regional mix of wind and PV installations with different mounting configurations in order to locally generate the annual electricity demand. It does so by adhering to three distinctive energy policy goals: economic efficiency, environmental sustainability and security of supply. The hourly yields of wind parks and nine PV orientations are simulated for four representative NUTS3-regions in Germany. These profiles are combined with regional electricity demand profiles and fed into an optimisation model. As a result, the optimal installed capacity for PV for every possible configuration – determined by inclination and azimuth angles – and the optimal installed capacity of wind power are obtained. The results indicate that the optimal mix differs significantly for each of the chosen goals, depending on regional conditions, but also shows a high transferability of general statements.
