Rahimafrooz Solar Home System
Rahimafrooz SHS is a solar home system that integrates a solar panel, batteries and accesories.
The Rahimafrooz Solar Home System (SHS) is a rooftop system that includes a solar panel, battery and accessories all made with locally manufactured materials in Bangladesh.
Bangladesh, Pakistan, and refugee camps in Africa.
Manufacturer and partner organizations such as the Rural Electrification Board (REB), Water and Power Development Authority (WAPDA), United Nations Development Programme (UNDP), United Nations High Commissioner for Refugees (UNHCR) and Bangladesh Power Development Board (BPDB) and others. The program has fund support from the World Bank, Gesellschaft für Technische Zusammenarbeit (GTZ), Asian Development Bank (ADB), and KFW by Infrastructure Development Company Ltd.Correspondence with manufacturer
Rahimafrooz competes with other solar home systems in Bangladesh. However, other comparable products available globally include Mobisol Solar Home System and Azuri Duo Solar Home System.
Goal 7: Affordable and clean energy
Off grid consumers and businesses.
All of the components are mass produced by Rahimafrooz Bangladesh Ltd. The solar panels are manufactured in an automated PV module manufacturing plant, while the batteries are manufactured with production machineries through a environment-friendly manufacturing process in a Rahimafrooz Accumulators Ltd facility.

Provided by the manufacturer.
The manufacturers specify a high load bearing capacity capable of resisting high wind forces and snow load due to special acrylic foam tape used to fix the frame, guaranteed electrical performance as cell strings are produced through automated soldering technology under uniform pressure and thermal process, and highest personal safety and module robustness as Hi-Pot tester carries out hi-potential and ground continuity test for individual panel as their performance targets.
If pressure is applied on the photovoltaic panel by sitting or stepping on it, the device might break and cause bodily injury or electrical shock. Precaution must be taken regarding electrical contacts or wiring, the person handling them must use adequate safety gear. To avoid electrical shock, the photovoltaic panel must be earth grounded. A minor risk of burns exists due to the heating of the photovoltaic panel’s surface by the sun.
Depending on the capacity of the system, appliances such as a TV, Radio or DC fan can be added.
