The power output of photovoltaics under standard test conditions, or STC, corresponds to a sunlight intensity of ___ at 25 degrees Celsius.

What voltage rating would you expect of a standard silicon solar module containing 60 cells?

You see a ground mounted solar array on the side of an apartment complex. The panels have a bluish flakey appearance that sparkles in the sun as you move around. What type of PV material are the cells in the panels most likely made of?

Which type of solar cells are currently the most efficient?

According to NREL, research grade silicon crystal (non-concentrator) solar cells have a maximum efficiency around _____.

What physical process explains how a solar cell functions when light hits the surface of the cell?

A single solar cell has a voltage around _________.

Which type of solar panel would you recommend to a customer who wants save money on a solar installation and can accept lower efficiency values?

A higher value of τα (transmittance-absorptance product) will result in a higher stagnation temperature.

Stagnation temperature is reached when the mass flow rate of the fluid is zero.
