This concept takes advantage of using the exhaust airflow of all-air heating, ventilating, and air-conditioning (HVAC) systems, and sun irradiation. For the first step, a parametric analysis of power generation from TEGs for different practical configurations is performed. Based on the results of the parametric analysis, recommendations associated with practical applications are presented. Therefore, a one-dimensional steady-state solution for the heat diffusion equation is considered with various boundary conditions (representing applied configurations). It is revealed that the most promising configuration corresponds to the TEG module exposed to a hot fluid at one face and a cold fluid at the other face. Then, based on the parametric analysis, the innovative concept is recognized and analyzed using appropriate thermal modeling. It is shown that for solar radiation of 2000 W\/m2 and a space cooling load of 20 kW, a 40 \u00d7 40 cm2 flat plate is capable of generating 3.8 W of electrical power. Finally, an economic study shows that this system saves about $6 monthly with a 3-year payback period at 2000 W\/m2 solar radiation. Environmentally, the system is also capable of reducing about 1 ton of CO2 emissions yearly.<\/jats:p>","DOI":"10.3390\/e22050503","type":"journal-article","created":{"date-parts":[[2020,4,28]],"date-time":"2020-04-28T05:05:32Z","timestamp":1588050332000},"page":"503","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["New Concept of Power Generation Using TEGs: Thermal Modeling, Parametric Analysis, and Case Study"],"prefix":"10.3390","volume":"22","author":[{"given":"Ahmad","family":"Faraj","sequence":"first","affiliation":[{"name":"Energy and Thermofluid Group, Lebanese International University (LIU), Bekaa 1801, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hassan","family":"Jaber","sequence":"additional","affiliation":[{"name":"Energy and Thermofluid Group, International University of Beirut BIU, Beirut 1001, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3100-1869","authenticated-orcid":false,"given":"Khaled","family":"Chahine","sequence":"additional","affiliation":[{"name":"Electrical and Computer Engineering Department, Beirut Arab University, Debbieh 115020, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jalal","family":"Faraj","sequence":"additional","affiliation":[{"name":"Energy and Thermofluid Group, International University of Beirut BIU, Beirut 1001, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamad","family":"Ramadan","sequence":"additional","affiliation":[{"name":"Energy and Thermofluid Group, International University of Beirut BIU, Beirut 1001, Lebanon"},{"name":"Associate Member at FCLAB, CNRS, University of Bourgogne Franche-Comt\u00e9, 90018 Belfort CEDEX, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hicham","family":"El Hage","sequence":"additional","affiliation":[{"name":"Energy and Thermofluid Group, International University of Beirut BIU, Beirut 1001, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahmoud","family":"Khaled","sequence":"additional","affiliation":[{"name":"Energy and Thermofluid Group, International University of Beirut BIU, Beirut 1001, Lebanon"},{"name":"Interdisciplinary Energy Research Institute (PIERI), University Paris Diderot, Sorbonne Paris Cite, 75000 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"535","DOI":"10.1016\/j.applthermaleng.2018.04.125","article-title":"Experiments on novel heat recovery systems on rotary kilns","volume":"139","author":"Du","year":"2018","journal-title":"Appl.
