- Development of a closed and open loop solar tracker technology Aurélio Gouvêa Melo Delly Oliveira Filho Maury Martins de Oliveira Júnior Sérgio Zolnier Aristides Ribeiro Ingeniería Solar energy dual axis tracking photovoltaic systems Solar energy is among the renewable energy sources that received greater addition in installed capacity. However, it accounts for a small frac tion of the energy matrix of most countries. Electric energy generation by solar systems can be improved through tracking. This work aimed to develop and compare a closed and an open loop solar tracking system. The closed loop system was developed using Light Dependent Resistors. An algo rithm was developed for the open l oop tracker as a function of the geometric relation between the sun and the photovoltaic module. A simulation was run to compare this algorithm with a system using tracking at fixed time intervals, for clear sky conditions, with different tracking parameters and for five di fferent latitudes. No significant difference was observed between the proposed open loop tracking algori thm and the fixed time interval algorithm for the tracking parameters evaluated. The open and closed l oop solar tracking systems were compared experimentally in Rio das Ostras, Brazil (22.49 °S 41.92° W). An average gain of 28.5% was observed for the open loop tracking system over a latitude tilted system and 33.0% for the closed loop tracking system. 2017 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303250905007 https://www.redalyc.org/journal/3032/303250905007/ https://www.redalyc.org/journal/3032/303250905007/html/ https://www.redalyc.org/journal/3032/303250905007/303250905007.epub https://www.redalyc.org/journal/3032/303250905007/movil en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
