Technologies

Technological innovation and evolution is a central part of the energy provisioning process at Lighting a Billion Lives©. The programme‚Äôs foremost mandate has been the development and provision of clean technology solutions that are relevant and customized to end user preferences, usage behavior and affordability. Since 2008, the programme has continually applied field experiences and feedback to improve, modify and advance its energy solutions to better suit end users.

Solar Charging Station (SCS)

Developed primarily to address basic lighting requirements for people who are not able to afford even kerosene lamps or candles, a solar charging station consists of 5 solar panels with capacities of 50 to 80 peak watts (Wp), and 50 LED solar lanterns which are simultaneously charged to provide lighting for 5 - 6 hours daily. The lanterns are rented out to households or small shops on a daily or monthly basis. The solar charging station generates a livelihood opportunity for men or women who function as village level entrepreneurs. Suitable for use indoors as well as outside, the solution brings flexibility to the end user, allowing them to take a lantern on hire only when required and paying only for what they use.

Solar Micro Grid (SMG)

Fixed, centralized installation of photovoltaic power panels that serve connections of 2 light points and a mobile charging facility across 50-80 households in a village, SMGs are well suited for households or shops situated close to each other or in a cluster, the solution is modular and flexible and can be expanded in scale as necessary. The connection to an SMG provides the end user with 4 to 5 hours of clean and bright lighting.

Solar Home Lighting System (SHLS)

Independent system installation that can be customized and configured to serve specific requirements and consumption needs of households and small shops. The system runs on its own solar panel and supports two to three light points and a mobile charging facility. End users may incorporate a small solar fan or television into the system by modifying the panel size and battery backup. The system is also well suited for isolated homes in rural belts that are too far away to receive a solar micro grid connection.

Integrated Domestic Energy Systems (IDES)

A hybrid version of the SHLS, the IDES is an integrated system that provides a clean cooking solution in addition to a solar panel, two light points and a mobile charging facility. Developed to address the other major concern of indoor air pollution in rural households, the system addresses basic lighting and cooking energy requirements and reduces emissions by 30%. The forced draft improved cook stove is improvised based on locally available materials and adapted to suit the region and usage behavior and is designed to provide 4 hours of cooking time in a day.
