The largest European PV wind hybrid system is located on the Pellworm Island in Germany (see http://www.pvresources.com/en/hybrid.php). The PV array has the capacity of 600 kW and will be enlarged with an additional 300 kW array. The first 300 kW array was build in 1983 and the second part was connected in 1992. This hybrid system is grid-connected. The eventual 900-kW capacity will enable the production of nearly 800 MWh/year.
