Using a pressure cooker with a solar oven is not a well-documented area of solar thermal cooking, but there are a few points that have been introduced for consideration:
- Using a pressure cooker may require a powerful solar oven in order to reach the temperatures necessary for effective results. A parabolic solar cooker may be a good choice.
- Plastic pressure cookers designed for microwave use should be avoided in favor of metal options as the plastic cookers may deform when exposed to the heat of a solar oven.
- As with the traditional use of a pressure cooker, a steam valve should be used to avoid the dangers of over-pressurizing the cooker.
- Of course care should be taken to make sure that the pressure cooker does not build up a pressure that could be dangerous.
