What is the PV effect? (best answer!)
Photovoltaic effect
Certain elements generating electricity when exposed to light
Solar modules in series creating more voltage
Solar arrays creating more current when wired in parallel
What is “STC” (include conditions)
Standard Test Condition: 77°F/25°C, 1.5AM, 1000W/m2
Standard Test Condition:212°F/100°C, 1.0AM, 500W/m2
Silicon Testing Center: 77°F/25°C, 1.5AM, 1000W/m2
Standard Silicon Crystals: 77°F/25°C, 1.5AM, 1000W/m2
What is the difference between mono-crystalline
silicon and poly-crystalline silicon?
mono is more expensive than poly
poly is not as efficient as mono
mono is from 1 silicon ingot while poly is from many ingots
All of the above
What tool is used to measure total or global irradiance?
pyrrheliometer
multi-meter
ampclamp
pyranometer
How much power is there when Voc = 40V?
0 W
40 W
Depends on the module rating
Unable to calculate with this information
How much power is there when Isc = 8A?
0 W
8 W
Depends on the module rating
Unable to tell with this information
What effect does heat have on a solar module?
Makes the more efficient
Brings voltage and current down
Brings voltage down
Brings current down
What effect does irradiance have on a solar module?
Makes them more efficient
Brings voltage & current down
Brings voltage up or down
Brings current up or down
What is the point where power is at maximum?
The knee of the IV cure: Pmax
The lowest point on the IV curve: Pmax
The highest point on the IV curve: Pmax
The point that gets the highest irradiance
