What happens when a cell in a PV module is shaded and there are no bypass diodes?

• The entire module stops producing power.

• The shaded cell produces more power.

• The shaded cell gets damaged.

• The module's efficiency increases.

What is the consequence of using dissimilar PV modules in series?

• Reduced overall efficiency

• Increased power output

• No effect on performance

• Enhanced voltage stability

What is the significance of the maximum power point (MPP) in a PV module?

• It is the point where the module produces the maximum voltage.

• It is the point where the module produces the maximum current.

• It is the point where the module produces the maximum power.

• It is the point where the module produces the maximum resistance.

Explain why Isc multiplied by zero volts results in zero power.

• Because any number multiplied by zero is zero

• Because Isc is always zero

• Because zero volts means no current

• Because power is independent of voltage

What happens if conductors are installed incorrectly and the insulation of the wire disappears or is damaged?

• It can cause short circuits.

• It will improve conductivity.

• It will have no effect.

• It will reduce electrical resistance.
