 Big thermocouple: 0,583V   Small thermocouple:0,318V   Both together:0,894V

 Big thermocouple:1,578V  Small thermocouple: 0,412V  Both together:1,185V

 Big thermocouple:0,145V Both together:0,325V Small thermocouple:0,122V

 Big thermocouple:0,443V  Small thermocouple:0,239V Both together:0,751V

 -Greater area of a solar thermocouple will get more energy  -solar thermocouples are inefficient because our two solar thermocouples are just able to power the appliance with the low voltage
