The differential expansion of three vertical thin flat strips with different orientations is amplified by a lever system to enable tracking of the apparent motion of the sun in the sky. A passive solar tracking system prototype supporting a photovoltaic (PV) module was built and tested. The model and experimental results show that the tracking system can correctly follow the azimuthal motion during the day. The tracking of solar elevation is less pronounced. The use of this tracking system leads to a 28% increase in PV generation during the testing period.<\/jats:p>","DOI":"10.1063\/1.5100492","type":"journal-article","created":{"date-parts":[[2019,7,16]],"date-time":"2019-07-16T13:36:58Z","timestamp":1563284218000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":14,"title":["Passive solar tracker based in the differential thermal expansion of vertical strips"],"prefix":"10.1063","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3580-3474","authenticated-orcid":false,"given":"Miguel Centeno","family":"Brito","sequence":"first","affiliation":[{"name":"Instituto Dom Luiz, Faculdade de Ci\u00eancias, Universidade de Lisboa 1 , 1749-016 Lisboa, Portugal"}]},{"given":"Jos\u00e9 M\u00e1rio","family":"P\u00f3","sequence":"additional","affiliation":[{"name":"Instituto Dom Luiz, Faculdade de Ci\u00eancias, Universidade de Lisboa 1 , 1749-016 Lisboa, Portugal"}]},{"given":"Daniela","family":"Pereira","sequence":"additional","affiliation":[{"name":"Instituto Dom Luiz, Faculdade de Ci\u00eancias, Universidade de Lisboa 1 , 1749-016 Lisboa, Portugal"}]},{"given":"Fernando","family":"Sim\u00f5es","sequence":"additional","affiliation":[{"name":"Active Space Technologies, Parque Industrial de Taveiro 2 , Lote 12, 3045-508 Coimbra, Portugal"}]},{"given":"Roberto","family":"Rodriguez","sequence":"additional","affiliation":[{"name":"Active Space Technologies, Parque Industrial de Taveiro 2 , Lote 12, 3045-508 Coimbra, Portugal"}]},{"given":"Jos\u00e9 Carlos","family":"Amador","sequence":"additional","affiliation":[{"name":"Formerly at Martifer Solar, Now Voltalia SA, Zona Industrial 3 , Apartado 36, 3684-001 Oliveira de Frades, Portugal"}]}],"member":"317","published-online":{"date-parts":[[2019,7,16]]},"reference":[{"issue":"Part 3","key":"2023063016341978400_c1","doi-asserted-by":"publisher","first-page":"2548","DOI":"10.1016\/j.rser.2017.09.077","article-title":"Advances in solar photovoltaic tracking systems: A review","volume":"82","year":"2018","journal-title":"Renewable Sustainable Energy Rev."},{"issue":"Part 1","key":"2023063016341978400_c2","doi-asserted-by":"publisher","first-page":"250","DOI":"10.1016\/j.rser.2017.06.085","article-title":"Recent advancements and challenges in Solar Tracking Systems (STS): A review","volume":"81","year":"2018","journal-title":"Renewable Sustainable Energy Rev."},{"key":"2023063016341978400_c3","doi-asserted-by":"publisher","first-page":"1671","DOI":"10.1016\/j.enconman.2003.10.006","article-title":"The effect of using sun tracking systems on the voltage\u2013current characteristics and power generation of flat strip photovoltaics","volume":"45","year":"2003","journal-title":"Energy Convers.
