Abstract

          This paper has studied the production of electricity from house roof heat using thermoelectric modules. Two halogen lamps 500watt were used to simulate the experiment with artificial light that was set to light intensity and radiation values close to that of sunlight. It is the conversion of heat energy on the roof of the house to electrical power. It increases efficiency by cooling with a heat sink or water block, which has tested electricity generation with a thermoelectric model TEG SP1848-27145 one module with 4 types of roofs: concrete tile roof, ceramic tile roof, fiber cement tile roof (double corrugated) and metal sheet roof. The test results showed that testing thermoelectric modules with water block cooling added to give the best voltage and current were the voltage of 129.0 mV, 125.2 mV, 143.0 mV, and 408.0 mV and the wind of 34.9 mA, 34.1 mA, 38.1 mA and 99.4 mA and the metal sheet roof gave the highest voltage and current of 408.0 mV, 99.4 mA respectively. And the water block cooling provides better voltage and current than the heat sink.
