Summary: This study investigates the combined wall and roof solar chimneys (SCs) both numerically and theoretically. The results show that the performance of the wall SC is generally enhanced when coupled with a roof SC. The window area has a significant impact on the roof SC but not the wall SC. Solar radiation has a positive effect on both the wall SC and the overall performance. Specific designs, such as big absorption walls, a big window, appropriate cavity gap and air inlet height for the wall SC, and a relatively small cavity gap for the roof SC, can achieve the optimized design of the combined system.

Summary: Human society is in a critical moment with the urgent need for rapid adoption of renewable energy sources to combat climate change and meet global energy demands. Simultaneously, agricultural production must increase significantly to feed a growing global population. The competition for land between crops and energy production, particularly solar photovoltaics, presents a challenge. However, a solution may lie in agrivoltaics - the co-location of agriculture and solar PV. This study investigates how agrivoltaic design features, such as panel height and ground conditions, can affect microclimate and solar module temperature, revealing potential benefits for both food and energy production.

Results show that the maximum thermal efficiency is achieved at wind speeds below 2 m/s and DNI above 950 W/m2. The utilization of the Nano-PCM layer as a cooling medium improves electrical efficiency compared to traditional systems.
