Solar Brother invites you to watch this video to learn how to build a parabolic solar cooker.

The video shows the step-by-step assembly of an 800mm diameter solar dish. Materials used: outdated 3/10 Alu Offset sheet in perfect condition and the S-Reflect mirror on a roll. This dish is very light (3kg) and easy to transport, with a compact 81 x 33 cm footprint. This tutorial will help you build your own low-cost parabolic solar cooker!

How does a parabolic solar cooker work?

This type of solar oven uses solar thermal energy according to 3 principles:
1/Concentration: Place the oven facing the sun. The mirrors receive the sun’s rays and focus them on the pot in the middle of the oven. They act as reflectors.

2/ Capture: the black or dark pot absorbs the sun’s rays without reflecting them back. IMPORTANT: do not use white or stainless steel, which reflect light.

3/ Storage: To ensure that the heat remains around the pot and that the temperature rises efficiently, place the pot in a transparent cooking bag (available in stores or on our website). It can also be surrounded by two glass or Pyrex dishes to reproduce the greenhouse effect.

For your safety
– Wear glasses to protect your eyes from mirror reflections when handling the oven in the sun.
– Wear protective gloves when removing hot food after cooking.
