Product Description

The solar mills, developed and distributed by Village Infrastructure Angels (VIA), are milling systems powered by solar energy. The solar power milling stations are intended to work in off-grid rural communities, where agro-processors need to walk several miles to the nearest mill or have to process their produce by hand. The mills are provided by leasing, and women entrepreneurs are especially encouraged to run the solar agro-processing stations. The mills are monitored remotely via IoT technology to track energy consumption and charge the batteries.

Village Infrastructure Angels was founded in 2012 in the United Kingdom and currently operates in the UK, Australia, and Vanuatu.

Design Specifications

The solar mills work using direct current at 24 V, driven directly from the photovoltaic modules without any current conversion stage. The solar milling system consists of a set of photovoltaic modules, batteries, and a charge controller. The system is monitored remotely via a SIM card provided by Eseye. The company offers seven kinds of solar mills developed by PSS, intended to different tasks: rice huller, corn sheller, flour grinder, or coconut/cassava grater.

Technical Support

Manufacturer Specified Performance Parameters

Village Infrastructure Angels has set the goal to serve with their products 1 million people by 2020. The solar mills can reduce the time of the hand-processing of staple crops from 1 hour to 5 minutes. By mechanizing this task, usually performed by women, the time saved can be used to support children's education. In particular, girls are avoided to be pulled out of school to help with manual agro-processing.

Vetted Performance Status



Users should be aware to properly handle the electric components of the mills. Additionally, batteries should not be opened, and in case of failure or misfunctioning of one of its components, it is recommended to contact the provider.
