“…As a result, solar chimneys designed with rectangular structures appear to be the optimal passive air-cooling system. Hussam et al [70] set up a test rig to conduct experiments on the impact of solar chimneys on solar panel performance, as shown in Figure 4. The solar chimney principle can effectively enhance wind speed to decrease temperature.…”

The efficiency of solar photovoltaic (PV) power generation is significantly impacted by factors such as ambient temperature, surrounding wind speed, and the temperature of the solar PV panels. The power generation efficiency of these panels diminishes by approximately 0.5% for each incremental rise in their temperature. To mitigate this effect, two primary methods for cooling solar photovoltaic panels are considered: active and passive cooling techniques. This review paper delves into an extensive body of literature on solar passive cooling systems, highlighting the vital role of passive cooling technology in enhancing the efficiency of solar PV power generation. We investigate the structure and cooling effect of diverse passive cooling systems, with a specific focus on the application of solar chimneys and ventilators in cooling systems for solar PV panels. Our study reveals that solar chimneys, using buoyancy, can decrease the temperature of solar PV panels by as much as 15 degrees, thereby augmenting power generation efficiency. Furthermore, the deployment of ventilator technology can boost the efficiency of solar PV power generation to an impressive 46.54%. In conclusion, this paper proposes the synergistic use of solar chimneys and ventilators to improve solar PV panel efficiency, extend their lifespan, and reduce the environmental impact resulting from inefficient solar PV panels. This comprehensive approach should inform future practices.

“…They emphasize that the efficiency range of the system is 16-18% and it is much more efficient than traditional SCPP systems. Some researchers use their small-scale SCPP systems to cool PV modules (Boutina et al, 2018;Hussam et al, 2022).…”

Güneş enerjisinin önemi fosil yakıtların son yıllarda yoğun kullanımı ile artan çevre kirliliği göz önüne alındığında insanlık için her geçen gün artmaktadır. Güneş enerjisinin önemi artarken mevcut güneş enerji sistemlerinin geliştirilmesi ve etkin kullanımı da önemlidir. Güneş enerjisini doğrudan ve dolaylı olarak kullanıldığı birçok sistem mevcuttur. Güneş bacası güç santralleri (SCPP) güneş enerjisini yapısındaki havaya aktararak dolaylı olarak güneşten elektrik üreten sistemlerdir. Kurulumundan sonra düşük bakım maliyetlerinin olması ve çevre dostu çalışma prensipleri ile gelecek vadetmektedir. Bu çalışma ilk olarak sistemin çalışma prensibini okuyuculara açıkladıktan sonra sistemin performansını etkileyen parametreleri değerlendirir. Daha sonra sistem ile ilgili son yıllarda yapılan yenilikçi çalışmalara değinir. Hibrit sistem olarak SCPP sistemlerine PV modül ilavesi, jeotermal ve dış ısı kaynağı ilavesi, deniz suyu tuzdan arındırma ve temiz su eldesi gibi çalışmalara yer verilir.

“…Natural ventilation can be provided in indoor environments without energy consumption by using solar chimneys [34]. By adding a solar chimney to PV modules, the temperature can be reduced, and performance can be improved by providing natural convection [35]. Jamali et al [36] evaluate the performance of the hybrid system using semi-transparent PV modules as SCPP collectors.…”

Solar energy systems can be an alternative to fossil fuels and are vital for a sustainable environment. It is promising that solar chimney power plants (SCPPs), which are among the solar energy systems, provide 24-hour power output (PO) and can work integrated with other systems. This study is based on the Manzanares pilot plant (MPP) and demonstrates satisfactory performance with an additional heat source to be integrated into the ground of the system during hours when solar radiation is weak. The performance of the system at different source temperatures is compared with the reference case, with the model verified using the RNG k-ε turbulence model through a 3D CFD study. In fact, it is seen that the PO of the system, which yields a PO of around 10 kW at 200 W/m2 solar radiation in the reference case, exceeds 80 kW with a source temperature of 200°C. From the results, it can be noticed that the system can also output power in the evening hours when there is no sun. With an additional heat source of 200°C during non-sunlit hours, the system gives more than 75 kW PO. This PO is 50% more than the maximum PO of 50 kW in the reference case.
