Surge in Solar-Powered Homes

Bangladesh has the world's fastest growing, off-grid solar home system (SHS) coverage. The number of SHSinstallations has risen phenomenally-from a five-year target of 50,000 in 2003 to 50,000 a month a decadelater. By early 2014, installations totaled more than 3 million. Even so, this figure represents just 10 percent ofthe country's off-grid households, suggesting ample room for continued program expansion.Surge in Solar-Powered Homes: Experience in Off-Grid Rural Bangladesh assesses the country's remarkablegrowth in SHS, its support schemes, and welfare impacts for rural households. Drawing on both large-scalehousehold survey and institutional data, the book's authors examine the effectiveness of SHS technology inimproving rural people's quality of life and the program delivery and financing mechanisms, including partialsubsidies, currently in place, administered by the Infrastructure Development Company Limited (IDCOL).The book's findings clearly demonstrate that the welfare benefits of SHS adoption far outweigh the socialcost of the subsidy. The benefits of lighting alone-replacing polluting kerosene lamps with solar-poweredelectric lighting-result in significant cost savings and income gains for adopter households. The findingsconfirm that SHS increases children's study time, households' sense of security, and women's empowerment.Within the current market incentive structure, there is tremendous scope for broadening the rural marketreach. But the high upfront cost of purchasing a SHS at current market prices is a barrier to future sales,suggesting the continued need for IDCOL's well-targeted subsidized operation.Bangladesh's highly successful SHS program leveraged a unique combination of geographical, institutional,and socioeconomic factors; however, certain elements could be easily replicated elsewhere. This bookwill be of interest to policy makers struggling with the task of increasing rural people's access to electricity,particularly in poor or remote areas where national grid extension is uneconomical. Developmentpractitioners can also benefit from learning about the welfare impacts of SHS on rural households andmarket-based implementation models designed to meet rural households' basic electricity needs.
