Fill Factor Formula
The following formula is used to calculate the Fill Factor.
FF = P / (V*I)
Variables:
- FF is the Fill Factor ( )
- P is the maximum power from the solar sell (W)
- V is the open circuit voltage (volts)
- I is the short-circuit current (amps)
To calculate a fill factor, divide the maximum power of the solar sell by the product of the open circuit voltage and the short-circuit current.
How to Calculate Fill Factor?
The following steps outline how to calculate the Fill Factor.
- First, determine the maximum power from the solar sell (W).
- Next, determine the open circuit voltage (volts).
- Next, determine the short-circuit current (amps).
- Next, gather the formula from above = FF = P / (V*I).
- Finally, calculate the Fill Factor.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
maximum power from the solar sell (W) = 30
open circuit voltage (volts) = 3
short-circuit current (amps) = 12FF = P / (V*I) = ?
