Question 1

What is the primary function of a Maximum Power Point Tracker (MPPT) in a solar PV system?

Accepted Answer

Optimize the operating voltage to extract maximum power from the panels

Answer

MPPT controllers continuously adjust the electrical operating point of the PV modules to extract the maximum available power under varying irradiance and temperature conditions.

Question 2

Which offshore wind foundation type is most suitable for water depths between 40–60 meters?

Accepted Answer

Jacket/lattice structure

Answer

Jacket foundations (lattice structures) are preferred for intermediate water depths of roughly 30–80 meters where monopiles become structurally inefficient.

Question 3

In a lithium-ion battery, what is 'State of Health' (SoH) used to measure?

Accepted Answer

Remaining useful capacity relative to original rated capacity

Answer

SoH compares a battery's current maximum capacity to its original rated capacity, indicating overall degradation over its service life.

Question 4

What is 'curtailment' in the context of wind and solar energy?

Accepted Answer

Deliberate reduction of renewable output to prevent grid overloading

Answer

Curtailment is the intentional reduction of renewable generation output below available capacity, typically ordered by grid operators to maintain system balance.

Question 5

Which solar cell technology achieves the highest single-junction theoretical efficiency limit, known as the Shockley-Queisser limit?

Accepted Answer

Approximately 33%

Answer

The Shockley-Queisser limit sets the maximum theoretical efficiency for a single-junction solar cell at approximately 33% under standard conditions.
