Hot Spots indicate a defect at cell level, where one or several cells have a higher temperature than the neighbouring ones..
Any imperfection in solar cells, such as cracks, poorly soldered joints, and mismatches, lead to higher resistance and become hot spots in the long run..
These small round hot spots of PV panels are mostly formed by abnormal heat at the power cord junction and long-term leaf hot spot occlusion, which is easy to eliminate the hot spots of PV panels. [pdf]

Solar PV modules are specifically designed to reduce reflection, as any reflected light cannot be converted into electricity. PV modules have been installed without incident at many airports..
Solar panels are designed to absorb sunlight and convert it into electricity, but they do reflect a small amount of light back into the atmosphere..
If more light is fed to the panels through a reflector, the temperature variations of the panels themselves will be greater, and the energy output is less predictable. [pdf]
