Research Team for Solar Milling Field Development and Research

In agricultural based economies of sub-Saharan Africa, grains (particularly maize) are typically the staple food crop. Off grid grain milling has the potential to increase farming efficiency, increase farmer revenue, and promote food security. Typically mills in off-grid areas are fuel powered and as a result have high operating costs and the potential for negative environmental impacts (e.g. pollution and GHG emissions from diesel generators). Where off grid (solar) mills have been tried, the available technology has been found to be inappropriate for the intended use case and no technologies have emerged that can compete with the incumbents.

Research conducted to date has not uncovered any mills in operation that utilize super-efficient brushless DC (BLDC) motors at scale accessible to Bottom of the Pyramid (BoP) end users. Agsol is a company working to change this. Agsol is manufacturing and supplying small agro-processing machines and intends to take these technologies to a global market.


The Efficiency for Access Coalition is seeking a researcher/research team to work closely with Agsol and CLASP to define a variety of use cases of off grid milling, provide a deep dive comparison of technologies and energy provision typologies, and test data collection methodology that could inform actors in the solar milling sector in Africa.

This project will require market, consumer and impact research into a productive use appliance that is of interest to several members of the Efficiency for Access coalition. The expectation is that the provision of this information will mobilize off grid milling companies to understand and address the potential market, and provide data on this market to off-grid energy providers and other distributors that are considering expanding their appliance portfolios to include solar milling appliances.

Please note that the Proposals will only be reviewed from firms or individuals who have completed the Low Energy Inclusive Appliances (LEIA) pre-qualification questionnaire.
