Customer ServiceI measured the temperature on and under solar panels sitting in the sun. It is MUCH hotter than any air being exhausted from a vehicle. As a matter of facts, the shading provided by the solar panels lowers the temperature inside the vehicle, and any air that is being ventilated. OP: there are a few roof vents that only need 4 to 6 inches of clearance, no

Customer ServiceThermal regulation process for the hydrogel bed cooled solar panel. Hydrogels spheres -with initial diameter before saturation of (1–2) mm and (8–10) mm diameter after complete saturation-were tested as a cooling bed for solar panels. Four different bed configurations were tested including: 1 raw bed, 2 raw bed, 2 raw with fins and 3 raw with fins.
The first step is the heat diffusion through the hydrogel bed beneath the solar panel, the second step is water desorption in form of water vapour that escape carrying the un-wanted heat from the system. The last step is to cool down the solar panel by more water desorption and heat removal as presented in Fig. 1.
Novel experimental work was done for cooling solar panels. Hydrogel beads were used with 4 different bed configurations. Average temperature reduction of approximately 10 °C was reached. At the highest radiation, electrical efficiency was improved by 7%.
Hydrogel beds with different configurations were tested as a stationary/passive back surface coolant for solar panels. Beds were formed with hydrogel spheres arranged as layers/rows. Four configurations were tested and compared with the un-cooled system.
It also has a relatively acceptable thermal characteristics to be used as an effective cooling agent for solar panels [ 17 ]. Hydrophilic gels, which are commercially called hydrogels, are promising substances for applications that required thermal regulation or hydration over a long period.
