Small-scale, distributed solar home systems provide an effective and affordable way to bring light to people without electricity in off grid areas. A basic system consists of a small solar panel, a battery, a charge controller, LED lights, and a universal outlet for charging cell-phones or other small appliances. Back in 1996, an innovative monthly installment based financial model introduced at the price of kerosene which has opened the door for Solar Home System (SHS). By following the path of this financial model, Silicon trading provides IDCOL approved products solar panel, solar charge controller, solar Batteries etc to Bright Green Energy Foundation (BGEF) and they have installed over 300,000 SHS in rural off-grid areas through its own network of over 300 rural branch offices all over Bangladesh.   Over 6 million SHS has been installed all over Bangladesh till now. Around 15% people of Bangladesh are enjoying modern Electricity from Solar Energy. It is the Largest Solar Program of the current world. In many developing countries specially in South East Asian & African countries are replicating this model inspired from Bangladesh.
