How does increasing temperature affect a PV module's voltage, current, and overall power output at fixed irradiance?

• A. Increasing temperature increases Voc and decreases Isc, boosting overall power.
• B. Increasing temperature lowers Voc significantly, increases Isc slightly, and can slightly reduce fill factor; overall power output typically decreases.
• C. Temperature has no effect on Voc.
• D. Power output increases with temperature at fixed irradiance.

Answer: (B)
