SOL5 — The Powerful, Sustainable Money Saver

Instead of buying fuel, use the free solar energy around you!
Roast, bake and dehydrate high quality with this smokeless 3.5 Kilowatt solar concentrator.

The SOL5 captures direct sunlight and turns it into heat for processes up to to 300°C.

The SOL5 has recently completed piloting in Kenya and Tanzania and we’re moving towards making the product available globally.

 

SOL5
Solar Heat Power For Food Processing

- Bakes 7kg of bread in 45 minutes

- Roasts 20kg of peanuts in 3 hours

- Dehydrates 20kg of Tomato in 8 hours

- Requires only direct sunlight, no fuel.

(No funds asked at this stage)

 

 

Multi-Use: The SOL5 Roasts / Bakes / Dehydrates

Roast

  • Can roast Peanut, Coffee, Cocoa / Cacao, Cashew and more.
  • No more burnt taste
  • Regulated temperature
  • Roasts 16kg of peanuts in 3 hours
  • No fuel costs
More

Because there's no fuel being burnt there's no hot spots that burn the beans and no risk of contaminating the roast with burnt fuel fuels or residues. Because sunlight is free there is no fuel costs and the SOL5 can pay for itself in less tha 2 years!

Bake

  • Can bake 500 cookies per day, 16 breads each batch
  • Up to 300°C baking temperature
  • Even heat distribution for high quality bakes
  • Immune to blackouts and brownouts
  • No fuel costs (requires sunlight, but the sun doesn’t charge :)
More

Bake at the same temperatures and quantity of a commercial tripple phase oven! Bake without fuel costs, without fuel or electric supply line. Bake without smoke!

Dehydrate

  • Can dehydrate fish, fruits, vegetables
  • Dehydrates 20kg of tomatoes in 8 hours
  • Faster drying method
  • Clean dehydration process (no more bugs)
  • No fuel costs
More

With a high temperature and high-power heat source, and a small PV pannel to force a rapid flow of air through the dehydrator, the SOL5 can dehydrate evenly, large quantities in short time. This significantly reduces risk of the sun going down while produce is still not fully dehydrated (compared to passive solar dehydrating methods). And of course, there are no fuel costs (compared with electric or fuel powered dehydrating)!

 


SOL5 Roadmap

We just completed a program of piloting and design iterations, and now entrepreneurs are successfully using the SOL5 to bake commercially in Kenya and Tanzania. Our next step is launching a network for fabrication so anyone anywhere can get a SOL5.

In low-income regions we are working with sponsors, foundations and NGO’s to train and capitalize local artisans to supply and maintain the SOL5 for their local economy.

For higher income regions we will be launching a lighter-weight shippable SOL5 for application developers, entrepeneurs and solar enthusiasts.
