Abstract
This project explores the application of Thermoelectric Generator (TEG) on concrete shingles with improvements by the introduction of a passive dual heatsink system. Driven by an internal convection in the roof to cool the cold side of the TEG equipped with a double-sided heatsink; one embedded in the concrete shingle and the other exposed to ambient air to be cooled. The project collects two main data, temperature, and power, as the performance matrix. Detailing the temperature data with three sample location, shingle, TEG, and ambient samples. Power in the form of voltage and current readings from the TEG. Mounted on a test platform that simulates residential roof structure sloped at 30 , with National Instruments Data Acquisition (NI DAQ) unit as the data logger. Compared to a previous system of a single heatsink located only on the underside of the shingle. The resulting comparison details an improvement of 0.735 mW/m o 2 and TEG thermal efficiency of 0.88 % with a 2.3 °C TEG delta. Improving the power generation from 0.23 nW to 2.38 µW at 45 °C.
