====== Photovoltaic electricity potential ====== In Switzerland the available/adequate surface for solar panels deployment is estimated to be 140 km2 for roofs and 55 km2 for frontages [[#References|[1]]]. Assuming that 40% of this surface is used for the installation of PV panels with a 25% electric [[pv_efficiency|efficiency]], then the photovoltaic potential is 25 TWh. ===== References ===== [1] [[|http://www.iea-pvps.org/index.php?id=9&eID=dam_frontend_push&docID=394]]
