Solar milling machine is designed to grind cereals and grains using solar power.
The Solar Milling is designed with same concept as any electrical mill, however, the 3-phase AC motor is connected directly to the grinding system, eliminating the need of conveyer belts, thus saving on energy which is lost due to friction. with a 3-pase AC motor which is connected directly to the grinding system. It does not require conveyer belt. The product has been discontinued by a new model.

Technical Support
The Solar Milling Small-Scale System can be purchased directly from Solar Milling SL.
Replacement Components
All spare parts are available from the Solar Milling company, although some can be locally found in any country.
Lifecycle
The solar modules are guaranteed to retain 90% of peak power performance for 25 years. The milling component is maintenance free, and is claimed to be very long lasting.
Manufacturer Specified Performance Parameters
Stone Mill output production (per machine) Small-Scale set includes one or two mill machines depending on the chosen configuration. Wheat: 35 – 150 kg/hour Maize: 35 – 150 kg/hour Barley: 30 – 110 kg/hour Millet: 25 kg/hour Teff: 40 kg/hour Sorghum: 35 kg/hour
Vetted Performance Status
Unknown
Safety
To avoid risk of electrical shock, all connectors are isolated. You’ll never be in touch with live electrical parts. The earth rod provided is highly recommended to be installed before the operation, to keep the entire equipment safe.

Feedstock type: must be dry grains as per “Wet grains could clog the stones and be not effective.” (http://solarmilling.com/faq/)
Add the note about solar operational requirements to achieve the stipulated feedstock rates (Note: Average Solar Operation Hours*: 6 hours/day).
– I think there’s a typo in the Container Volume section of the Performance Parameters section at the top – it should be listed as 20 L.
– “Replacement Components: These are produced in-country,” – is this supposed to mean that they are available for purchase as replacements in those countries? Like the tap, for example?
– “Testing Organizations – Testing is done through the CDC” – this is unclear. What kind of testing?
