35 Renewable Energy : Solar Subject experts provide criteria for GIS analysis to determine area with the highest Photovoltaic (PV) capacity potential PV generation capacity by municipal district PV yield of a Silicon PV panel. The resolution of this layer is 1 x 1 km and is based on 12 years of solar and temperature data. The modelling was done based on 15 minute time steps. Typical fixed tilt PV installation 35

36 Renewable Energy : Wind The legend in the figure relates to the IEC wind classes as derived for a hub height at 80 m. In general a wind class 4 (dark green W/m 2 ) and up is economically exploitable. However recent developments in wind turbine technology and manufacturing cost are rendering wind class 3 (light green) also economically exploitable but in this study it is not included
