Solar panels can heat the rods
Cylindrical rods are shown to transmit heat from the solar plate to the surrounding environment in numerical analysis. By increasing the wind speed by 0.4 m/s, the surface temperature of a PV module drops by 0.4196 °C, which is the influence of air velocity on heat transfer from the module.

Combining solar panels with phase change material (PV/PCM) cooling has increased significantly recently. Unlike other active cooling systems, PCM incorporating solar cells does not require heat transfer fluids or moving elements to absorb the excess heat generated by the PV module.
When exposed to concentrated solar radiation equivalent to 135 suns, the absorber plate reached 1,050°C, while the quartz rod’s front face remained at a relatively cool 450°C. What makes this new research compelling is the potential efficiency improvement of solar receivers using thermal trapping.
For tracking purpose, usually magnetorquer rods, reaction wheels and permanent magnets are used, but they are heavier, expensive, and occupy extra space on the spacecraft. Keeping in mind the dimension, budget and mass constraints of small satellites, a system compatible with small satellite is worth consideration.
Combining photovoltaic modules with solar collectors allows for the simultaneous generation of heat and electricity, what is known as solar photovoltaic/thermal technology which improving the overall efficiency of the system while increasing the space utilization.
