PV Gap

Tracy Said:

difference between Poly-Crystalline Solar Panel and MONO-CRYSTALLINE?

We Answered:

i think the type of semiconductors used.
they're different in the open circuit voltage, short circuit current, efficiency, and fill factor.

Jimmy Said:

What light bulb is effective to produce an output voltage reading on a pv panel?

We Answered:

For a PV lab for a night school class a halogen work light gave enough to do some experiments.
Once you have enough light to get an output voltage, more light does less to increase the voltage than it does to increase the current or power output.
