With only 10-15 watts of solar power, this prototype mini solar electric cooker can cook an egg, boil water or cook food. The power source is just a 20-watt 12 volts solar panel. The cooker uses a solid state heating element to convert direct DC solar power to heat. Because a diode chain can act similar to an MPPT circuit, it extracts more heat from the solar panel under a variety of changing solar conditions. It's possible this tiny solar cooker broke a world record, as it reached near boiling temperature at just 3.0 to 5.8 watts of power. Further testing will be undertaken to see what the limits are.
I made this prototype to demonstrate what a diode chain or diode string can do with a small solar panel to cook food. Combining an insulated container with a diode chain can make an effective and efficient solar electric cooker.
🟢 Larger sized portable cooker in development - hope to show that one soon.
The potential applications include camping, hiking, austere situations, survival, remote sites and rural areas where times are tough and cooking fuel is hard to get.
