Under direct sunlight, panel temperatures can easily climb to 50-65°C (122-149°F) or even higher, depending on factors like air temperature, solar irradiance, wind speed, and the roof material. The primary challenge in hot climates is the efficiency decrease caused by elevated.

In real-world conditions, solar panels typically operate 20-40°C above ambient air temperature, meaning a 30°C (86°F) day can result in panel temperatures reaching 50-70°C (122-158°F).
