Cooking power at pot
933 W
How to Use This Calculator
- Enter the dish diameter and depth of your parabolic reflector.
- Set the reflector reflectivity (0–1) and current solar irradiance (W/m²).
- Enter the diameter of your cooking pot.
- The calculator outputs cooking power at the pot, focal length, concentration ratio, estimated max temperature, and time to boil 2 liters.
- Adjust dish diameter or reflectivity to explore trade-offs between power and construction complexity.
