The vast majority of field engineers who sell, install and maintain SHS in Bangladesh have received a diploma in engineering from the Bangladesh Technical Education Board. These engineers, many of whom are women, also train less educated women on how to construct and repair component parts of solar PV systems, which creates a positive effect cascading down to less educated workers. To aid in this effort, the Government set up the financial institution IDCOL (Infrastructure Development Company Limited) in 1997, with financing from the World Bank. To ensure quality standards, these organizations are required to sell components approved by a technical standards committee, including experts from Government, the rural electrical agency and the technical university.
