Joan’s bread is better than any other. So yummy! Her solar bakery is the best bakery in town. — Sylvia Atayi, Elgeyo Marakwet Cluster Manager, World Vision Kenya

With the solar roastery business model, we can see that based on their performance they can reach an income of 160€ per month" — Allen Odongo, Bakery Trainer, with Plan International in Uganda

The solar bakery reached a turnover of 123€ per month" — Champion’s Bakery in Ogur (with Plan International in Uganda)

We are able to save 500€ per month of buying bread that we now bake ourselves, and on top of that, the solar bakery brings an income of 260€ every month from additional sales" — Mwanza Montessori School, Tanzania

Lytefire Impact Calculator

Each time you install a Lytefire, every sunny day you’ll get energy without polluting. Select the quantity of Lytefire you need:

8 Lytefire have the following impact each year:

36 tons CO₂
not emitted (CO₂eq)

73 440 baguettes baked *

African baguettes are about 40cm in length and 150g.

or 55 323 meals cooked **

650g of cooked rice and beans
800 calories per meal

81 trees
or 594 m² of forest preserved

* African baguettes are about 40cm in length and 150g.

** 650g of cooked rice and beans
800 calories per meal

This impact comes when replacing firewood as a fuel

How this impact is calculated →

Amount of breads baked per day on average (in kg):

kilograms

30-40kg of breads baked per day is a value from real solar bakers in Kisumu, Kenya, although higher amounts are technically possible, this depends on the day-to-day activities of the bakery.

Amount of sunny baking days per year:

workdays

The average number of solar days depepnds on the local climate. Estimate providede for Kisumu, Kenya.

Amount of firewood used per kilogram of bread baked:

kg firewood / kg bread

This depends on the efficiency of the ovens used before Lytefire and the energy density of the wood. A 2014 study in Mozambique found 0.9kgs of firewood used per 1kg of baked bread in pre-heated wood-ovens (source).

Amount of CO₂ emitted per kilogram of firewood:

kg CO₂eq

Average weight of firewood per tree in kilograms:

kg / tree

Varies greatly depending on forest. 127kg is based on Grevillea robusta harvests in Embu, Kenya (source).

Average number of square meteres per tree:

m² / tree

Varies greatly depending on forest. The higher the number, the less dense the forest. A 3 by 3 meter spacing per tree results in 9m² per tree.

Your 8 Lytefire are preserving each year 81 trees

Delicious food!

Cooking, baking, roasting with direct solar energy doesn’t change the taste of food. With this system, it is also possible to can food, or even to create a micro-brewery.

We prepare for the future all together.

I believe in Lytefire because it’s a simple, robust and powerful clean energy solution. It can be built locally just about anywhere. It doesn’t require complexity to be built, used and maintained. That is why it is also important and urgent to spread it and train the youth.

I also love Lytefire because it allows people to be more autonomous without pollution, it reinforces gender equality and it strengthens the local economy. Its impact is real and immediate.

Energy is a common good. And Lytefire’s team is proud to spread access to clean energy with you."
