## Solar Panel Voltage Formula

The following formula is used to calculate the Solar Panel Voltage.

Vsp = C * Vpc

Variables:

- Where Vsp is the Solar Panel Voltage (volts)
- C is the total number of cells
- Vpc is the voltage per cell (volts/cell)

To calculate the solar panel voltage, multiply the number of cells by the voltage per cell.

## How to Calculate Solar Panel Voltage?

The following two example problems outline the steps and information needed in order to calculate the Solar Panel Voltage.

**Example Problem #1:**

- First, determine the total number of cells. In this example, the total number of cells is measured to be 100.
- Next, determine the voltage per cell (volts/cell). For this problem, the voltage per cell (volts/cell) is calculated to be .45.
- Finally, calculate the Solar Panel Voltage using the formula above:

Vsp = #C * Vpc

Inserting the values from above into the equation yields:

Vsp = 100 * .45 = 45 (volts)

**Example Problem #2: **

Using the same process as the first example, define the variables outlined by the formula. In this case, these values are:

total number of cells = 50

voltage per cell (volts/cell) = .35

Entering these values into the formula or calculator above gives us::

Vsp =50 * .35 = 17.5 (volts)
