Practice Questions

Question 1

Which issue arises due to spectral mismatch in PV modules under real-world irradiance conditions?

Question 2

A PV module has open-circuit voltage $V_{oc}=38\,\mathrm V$ at $25\,^\circ\mathrm C$, temperature coefficient of $V_{oc}$ of $-0.28\\%/\!^\circ\mathrm C$, short-circuit current $I_{sc}=10\,\mathrm A$ with coefficient $+0.05\\%/\!^\circ\mathrm C$, fill factor $FF=0.75$, and receives irradiance $800\,\mathrm W/m^2$ at cell temperature $45\,^\circ\mathrm C$. What is its approximate maximum power output $P_{max}$?

Question 3

Two PV modules have measured short-circuit currents $I_{sc}$ of $9.0\,\mathrm A$ and $9.3\,\mathrm A$ due to manufacturing tolerances and are connected in series under uniform irradiance. What current will flow through the series string?

Question 4

What is the primary function of anti-islanding protection in a grid-connected PV inverter?

Question 5

Module-level power electronics (MLPE) such as microinverters or power optimizers primarily serve to:
