Small Wind Energy Systems

Renewable energy has become very important both worldwide and on the European market, mainly due to the decrease in the photovoltaic (PV) system cost (up to 75%) during the last decade. PV installations worldwide have reached 227 GW at the end of 2015 with a predicted extra 50 GW of new installation in 2016. Residential systems are a key element in the success story of PV rooftop installations. This chapter discusses the design of residential PV installations, with focus on rooftop grid-connected systems, which represent the vast majority of small-scale PV systems.
