Thermoelectric Generator Vs Solar Panel

High performance flat panel solar thermoelectric generators with high thermal concentration.

Thermoelectric generator vs solar panel.

Wood stoves equipped with thermoelectric generators also produce electricity which can be more sustainable more reliable and less costly than power from solar panels.

Wood stoves can provide a household with thermal energy for cooking and for space and water heating. A thermoelectric generator teg also called a seebeck generator is a solid state device that converts heat flux temperature differences directly into electrical energy through a phenomenon called the seebeck effect a form of thermoelectric effect thermoelectric generators function like heat engines but are less bulky and have no moving parts. A thermoelectric generator can be made using bimetallic materials but the result often is bulky and expensive. However tegs are typically more expensive.

We note that an appropriate pv panel is used for powering different thermoelectric modules. It obtains the heat for operation from the sun to heat the hot side of the teg and uses cool ocean water to cool the opposite side. A solar system that keeps topping up your battery will significantly reduce your generator s run time saving you and your campsite neighbours from the noises and fumes. The sunflower is a passive solar device i designed that uses a thermo electric generator teg module.

Reed said combining free solar power with a vehicle charging system makes a virtually self sufficient auxiliary battery power system possible. From a panel surface of 1 m2 thermoelectric solar panel has generated 4 kw electric power while from the same surface photovoltaic panel has generated 132 w only. I used a peltier thermal electric cooler and a satellite dish to generate electricity. Unlike solar cells however these devices can operate anywhere there is a heat source day or night.
