The "fill factor", more commonly known by its abbreviation "FF", is a parameter which, in conjunction with V oc and I sc, determines the maximum power from a solar cell. The FF is defined as the ratio of the maximum power from the solar cell to the product of V oc and I sc so that: $$FF= frac{P_{MP}}{V_{OC}times I_{SC}}$$ Fill Factor

Determine the solar panel capacity by dividing the daily energy production requirement by the average daily sunlight hours. Account for panel derating to factor in efficiency losses. Divide the actual solar panel capacity by the capacity of a single panel to determine the number of panels needed.
For the measurement of module parameters like VOC, ISC, VM, and IM we need voltmeter and ammeter or multimeter, rheostat, and connecting wires. While measuring the VOC, no-load should be connected across the two terminals of the module. To find the open circuit voltage of a photovoltaic module via multimer, follow the simple following steps.
In short, the current produced by a solar panel can be calculated by dividing the power rating (in watts) by the maximum power voltage (Vmp). As an example, if the solar panel is rated at 300 watts and the Vmp is given as 12 Volts, the calculation will look like this: I = P / V Read the above as current equals power divided by voltage.
While measuring the ISC, no-load should be connected across the two terminals of the module. To find the short circuit current of a photovoltaic module via multimer, follow the simple following steps. Make sure that one probe is connected to the COM port of multimeter and another to the current measuring port.
