Experimental analysis of innovative perforated heat sinks for
The simultaneous conversion of solar energy into electric and thermal energy using photovoltaic-thermal panels is known in the literature as PVT (Photovoltaic-Thermal System) [27], [30], [31], [32], [33].A particular feature of this solution is the BIPVT concept, which implies the integration of photovoltaic panels into buildings [36], [37].The generation of two of
Field thermal performance of naturally ventilated solar roof with
During winter, the experimental roof was expected to work as a passive solar collector storing solar heat absorbed during the day, and increasing overall attic air temperature during the night. During summer, the PCM was expected to act as a heat sink, reducing the heat gained by the attic and consequently, lowering the building cooling-loads.
Impact of Different Rooftop Coverings on Photovoltaic Panel
To use low energy air blowing system, Hussien et al. [18] attached several Directe Current (DC) fans to the duct and estimated a 1.34% efficiency improvement. In other techniques, the lower surface of the PV panels provided several configurations of heat sinks [22 – 26]. The results showed an improvement in the PV system''s performance due
