Bu çalışmada, Balıkesir Üniversitesi Çağış kampüsünde kurulan hibrit fotovoltaik termal (PV/T) bir sistemin elektriksel ve termal çalışma performansları incelenmiştir. Kurulan sistemin, şebeke bağımsız olarak akülerle birlikte elektriksel çalışma performansı değerlendirilmiştir. 0.015, 0.044 ve 0.069 kg/s’ lik akışkan hızlarında yapılan ölçümlerde sistemin termal veriminin %49.9 ile %52.11 arasında değiştiği görülmüştür. Ağustos ayı için, belirlenen elektriksel yük profilinde, sistemin şebeke bağımsız elektriksel performans incelemesi sonucunda akülerle yük besleme yaparken şarj durumu %40 ile %100 arasında değiştiği belirlenmiştir. Ayrıca PV/T panelin soğutmalı ve soğutmasız durumlarda elektriksel performansı incelenmiştir ve soğutma yapıldığı durumda elektriksel çıkış maksimum güç noktasında %12.9’ luk bir artış belirlenmiş ve bu değerlerde elektriksel verim %12 olarak hesaplanmıştır.
In this study, the electrical and thermal work performance of a hybrid photovoltaic thermal (PV/T) system founded at the University of Fiskesir Call campus was studied. The electrical performance of the established system is assessed with the batteries independently of the network. Measures at fluid speeds of 0.015, 0.044 and 0.069 kg/s showed that the system’s thermal efficiency varied from 49.9% to 52.11%. For the month of August, the identified electrical load profile determined that the system was carried by batteries as a result of the network independent electrical performance assessment, while the charging status varied between 40% and 100%. In addition, the PV/T panel’s electrical performance in cooling and non-colding situations has been studied, and in the case of cooling, an increase of 12.9% in the maximum power point of electric output has been determined, and the electrical performance is calculated at 12% in these values.
In this study, electrical and thermal performances of a hybrid photovoltaic thermal system (PV/T) which built in Balıkesir University Campus area were investigated. The off-grid electrical performance of the system with batteries has been evaluated. It is found that the thermal efficiency of this system changes between 49.9% and 52.11% by the measurements in 0.015, 0.044 and 0.069 kg/s flow rates. In August, the state of charge of batteries change between 40% and 100% while the system feeds the specified load profile. Additionally, the electrical output of the cooling and uncooling of PV/T panel in the maximum power point were compared resulting approximately 12.9% increasing power. The electrical efficiency has been calculated as 12% for cooling system.
