The Solar PV Rice Huller kit, manufactured by Project Support Services (PSS) is a DC motorized agro-processing appliance energized through a PV module. The kit has been designed for rural rice farmers that want to step-out from subsistence production.
The system’s modularity allows adding more PV modules to increase production from 60 kg/day up to 300 kg/day. Additionally, the rice huller can be complemented with a rice polisher without buying new components. The kit also provides access to energy for other uses, including 2 LED tube lights, 12 V lighter socket outlets, and a mobile phone charger kit.
Project Support Services designs and manufactures DC solar powered agro-processing appliances which have been implemented in Papua New Guinea, the Pacific Islands.
Since 2010, this product has been manufactured in China by PSS at its logistics and supply facility near Shenzen, Hong Kong.

The Solar PV Rice Huller Kit is composed of the PSS Power Platform, an adaptable power unit capable of running multiple machines and devices. The platform contains the Smart Solar Control Box, which has high amp 24V outlets to power milling machines, clean water supply, small businesses, or a mini-grid. It also has low amp 12V outputs for lights, phone chargers, and small appliances. The basic unit can produce 60 kg of brown rice per day, but adding up to 5 solar panels this production can increase up to 300 kg/day. It can also be added to a rice polisher machine by plugging it into the Power Platform. The package includes 2 LED lube lights, a 12V lighter socket outlet, and a mobile phone charging kit. Additional LED lights and cables can also be added.
This product is designed such that the replacement components are available in local stores. When this is not possible, replacement components are provided by the manufacturer.

Manufacturer Specified Performance Parameters
With this product, the company aims to address two issues:
- Reducing the time and energy that people from poor communities spend in processing essential food crops, especially women and children.
- Improve the access to clean and affordable energy for rural, off-grid communities in developing countries, allowing them to access to household lightning and power, clean water systems, refrigeration, communication equipment, and more.
Vetted Performance Status
Users should be aware to properly handle the electric components of the system. 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.
Complementary Technical Systems
This system can be complemented with the PSS Rice Polisher, additional PV modules to increase output, additional LED lights, and cables for phone and small appliances charging.
