Turning sunlight into value for entrepreneurs

Technology

Our SOL models capture direct solar energy and make it usable at low cost over a large temperature range.

SOL for small scale businesses

Up to 6kW

POWER OUTPUT of thermal heat energy, suitable for small-scale commercial activity such as local baker.

Up to 300°C

TEMPERATURE within the application. The focal point is much hotter, but what matters is the temperature that can be reached and sustained throughout a working day.

0.5 to 10

OPTICAL SURFACE, such as normal "bathroom" mirror, will reflect the sun’s light onto the focal point to power the application.

$350-900

MATERIAL COST if you build with retail steel and mirror prices. Labour costs depend on location.

 

Quick Facts

- The number (Sol1, Sol4, Sol5, etc.) indicates how many square meters of mirror the model has.
- Sunlight has about 1000 Watts of radiative energy per square meter (at noon on a clear day).
- Our concentrators convert that incoming radiative energy to "usable heat energy" at about 60% efficiency (depending on a lot of factors, like build quality, application and dust accumulation).
- So, for instance, our SOL5 model has 5 square meters of mirror and powers a 3 kW oven at 200° Celsius.


SOL5 Roaster

The SOL5 Roaster model has 5 square meters of mirrors that focus the light on a roaster application, making it possible to roast peanut, coffee, cacao.

- Roasts 20kg of peanuts in 3.5hrs
- Roasts 15kg of cocoa beans in 2 hours

Used in our project Kenya and Tanzania.

SOL5 Oven

The SOL5 Oven model has 5 square meters of mirrors that focus the light on an oven application, making it possible to bake.

- Bakes 100 scones in 35 minutes
- Bakes 30 x 200g loaves of bread in 45 minutes

Used in our project Kenya , Tanzania and New York City, USA.

SOL4 Oven

The SOL4 Oven model has 4 square meters of mirrors that focus the light on an oven application, making it possible to bake.

- Bakes 30 muffins in 35 minutes

W:3m, L:4m, H:2m

FOOTPRINT The SOL4 rotates to follow the sun and requires a 3.5m circular area free from shade

SOL4 Cooktop

The SOL4 Cooktop model has 4 square meters of mirrors that focus the light on a cooktop for cooking, frying and boiling.

- Can scramble 24 eggs in around 6 minutes
- Boils 8L of water in 30 minutes
- Makes one grilled cheese sandwich per minute
