14. Power Extraction from Several Interconnecting Solar PV Networks for an Electrically Integrated TEG System Under Weather Fluctuation

With the extensive demand for energy harvesting systems from various renewable resources, researches have been carried out in several areas among which thermoelectric generator (TEG)-based system is an emerging one. In this paper, eight solar PV modules are interconnected in numerous fashions in order to investigate the behavior of the hybrid system. The transiency of the solar PV modules inside the network has been examined under healthy irradiance and sectional irradiance. Rise in solar concentration tends to decrease the solar PV module efficiency, and this curse to solar PV becomes the boon to the TEG giving rise to higher power output at the terminals. Incorporation of solar photovoltaic (SPV) and thermoelectric (TE), termed as Solar photovoltaic-thermoelectric (SPV-TE) hybrid system is found be a very promising technique to broadening the utilization of solar spectrum and enhancing the power output effectively-cum-efficiently. This hybrid architecture caters electrical energy with additional thermal energy that signifies upon harnessing of solar insolation in an exceptional way.
