The mission of GS is to provide rural people with access to environment-friendly and pollution-free energy at affordable costs. Already, over 205,000 homes across Bangladesh have installed photovoltaic (PV) solar systems capable of powering lights and small-scale electronic appliances (so called solar home systems - SHS). Over 8,000 PV solar systems are being installed per month, and demand for the systems is increasing exponentially. The goal is to install 2 million such systems in homes by 2011 and 7.5 million by 2015, which would serve half of the total rural population of Bangladesh.
