About Voltage drop of photovoltaic panel
Calculating voltage drop involves using the formula: Voltage Drop = 2 x L x I x R / 1,000, where L is the cable length in meters, I is the current, and R is the resistance per kilometer.

Free online calculator to compute voltage drop and energy losses in a wire. Losses in solar PV wires must be limited, DC losses in strings of solar panels, and AC losses at the output of inverters. A way to limit these losses is to minimize the voltage drop in cables.
First and foremost, the antiquated 2% DC voltage drop assumption should be rethought. Our analysis shows that this long-held rule of thumb no longer applies to most commercial and utility-scale PV projects. As system voltages and ILRs have increased, the magnitude and importance of DC voltage drop has faded.
Experienced PV engineers have likely heard of the “2% DC voltage drop” rule of thumb, which we analyzed back in 2020. In this article, we will cover the concepts and calculations behind voltage drop – what it is, why it matters, and how to determine voltage drop losses for DC and AC conductors.
Voltage drop (VD) is the loss of voltage in a circuit due to the resistance in the electrical circuit. To determine the amount of voltage lost in a circuit, we need to look at three parts: 1. Resistance of the conductor in Ohms (Ω), 2. The length of the circuit conductor, 3. The current flowing through the conductor.
