摘要

This study targets to maximize the capture of solar irradiance by a photovoltaic panel (PV) and a photovoltaic thermal (PV/T) collector by means of a single-axis solar tracking mechanism. The experimentally tested single-axis solar tracking photovoltaic (PV₂) panel and the PV/T collector energy and exergy data compared to a fixed photovoltaic (PV₁) panel. At test, PV₁ panel received 649 Wh of solar energy. Solar tracking enabled 731 Wh of solar energy to reach the PV₂ panel and the PV/T collectors. PV₂ generated 56 Wh of electrical energy by harnessing more solar energy through solar tracking. PV₁, by contrast, provided 41 Wh. The PV/T collector, benefiting from both air-cooling and solar tracking, yielded the highest output: 61 Wh of electrical energy and 201 Wh of thermal energy. Solar tracking boosted the energy efficiency from 6.32% in PV₁ to 7.61% in PV₂. The exergy efficiency of PV₁ was 4.09%; this was improved to 5.26% in PV₂. Solar tracking and air-cooling enhanced energy and exergy efficiencies to 35.88% and 9.07%, respectively, in PV/T configuration. The findings demonstrate that combining cooling and solar tracking in PV/T improved solar energy harvesting of PV technology even more.
