ISA & CSE's report elaborates how solar can complement grid and provide access.
A solar photovoltaic (PV) system mounted on a rooftop of a building is a minipower plant that converts solar energy into electricity to meet the property's power requirements or feed into the grid.
Germany has made remarkable progress in deployment of renewable energy. This energy transformation or ‘Energiewende’ from fossil fuel to renewable energy is attributed to German policies with particular focus on feed-in tariffs. It has encouraged solar rooftop installations and as of Dec 2013, Germany had an installed capacity of 8.7 gigawatts (GW) of solar rooftop.
