Solar Bakery: Bread and Pastries baked with the SOL5 Oven

In East Africa our SOL5 solar concentrators replace costly and unstable electricity, firewood and charcoal with direct solar energy. This powerful technology is a solid choice for baking up to 300°C / 572°F.

When it comes to performance, 1 SOL5 can bake 500 cookies per day and 2 SOL5 Ovens have the capacity to bake 80kg of bread per day.

On top of that, the SOL5 is built using local materials so it can be fully maintained; all parts can be replaced and purchased in most towns and every city we’ve come across in Kenya, Tanzania and Uganda.

One SOL5, prevents up to 16 431 kg of CO2 emissions per year.

Bakers are already using the SOL5 solar oven full-time in Kenya, Tanzania and Uganda.

In Tanzania and Kenya, entrepreneurs are using our hybrid SOL5 Oven/Roaster and can also roast peanuts, coffee and cocoa.

-> For bakers the SOL5 Oven will soon be available on the market.

If you are interested, please fill the form below so we can notify you when the SOL5 is available in your region.

-> As an NGO, government, school or sponsor, get in touch with us to see how we can collaborate and spread the SOL5 Oven and our other solutions for baking, roasting nuts & coffee, dehydrating plants, fish, veggies and fruits in order to empower more and more solar entrepreneurs with sustainable living.

“The SOL5 Oven is giving us 275 Kenyan shillings per day, but with the charcoal oven it’s only 75 shillings. That’s the difference.” -

Solar Baker #1: David Chepkwone

It was an exciting moment when David pulled out the first batch of freshly baked muffins from his SOL5 Oven. This was back in 2016, and David continues to use the very same SOL5 today!

Before working with the SOL5, David used to spend money on electricity and charcoal. But the grid was so bad that he couldn’t develop his business properly. When the power was out he couldn’t bake, and with charcoal his product would be low-quality and his profit margins would be slim. With the launch of his solar bakery, David has been able to reduce his fuel costs and increase his output! The shiny SOL5 also attracted many visitors to his rural bakery, and so he decided to open up a small cafe to sell snacks and beverages to the interested crowd.

With a clean energy source adapted to his needs, now David can be a creative and productive baker.

“Now we have the oven here, and it gives us direct
income. The impact is that we used to use the charcoal
oven which gave us hard times. We only use the sun,
the rays from the sun.”
- Martha Ochieng, Baker, Misire Group

Solar Baker #2: Arnaud Crétot

GoSol CTO Arnaud Crétot.

Arnaud, our Chief Technical Officer, is a world class thermal engineer, software developer and has audited over 50 energy projects in Europe and Asia before joining GoSol to develop the SOL5 energy solution.

But Arnaud is also a passionate baker and has recently completed a certificate course in artisan bread making. On top of that, he’s launching a new business solar roasting nuts in France.

With Arnaud we were able to engineer the SOL5 from a real baker’s perspective and be able to understand the feedback and data from our bakers in Kenya, Tanzania and Uganda. One of the key things we realized is that the knowledge needed to run a bakery successfully sometimes is missing, and to solve this we’ve developed a training course specifically to empower new entrepreneurs.

Just recently we completed the first training courses to equip and train new entrepreneurs. We are proud to report that the entrepreneurs we trained are still running sustainable solar bakeries and making profits with solar energy. We are excited because this finally is economic growth that reduces CO2 emissions instead of increasing it.
