Question 1

Why do bifacial photovoltaic modules produce higher output than monofacial panels?

Accepted Answer

Bifacial PV modules capture solar radiation on both the front and backside. This increases energy generation, especially in locations with strong reflected sunlight and where albedo is higher.

Question 2

What problem motivates using nonbiodegradable waste as reflectors?

Accepted Answer

Conventional reflectors can discolor and degrade over time, increasing replacement and total implementation cost. Their disposal may also negatively affect the environment depending on material type.

Question 3

Which nonbiodegradable reflector material performed best in the study and what were the reported efficiency results?

Accepted Answer

PVC flex enhanced bifacial PV performance better than polystyrene foam and aluminum foil. The study reports average power of 224 W, average energy efficiency of 27%, and average exergy efficiency of 31% for the PVC flex case.
