When designing a solar PV system it’s critical to know the minimum and maximum number of PV modules that can be connected in series, referred to as a string. PV modules produce more voltage in low temperatures and less voltage in high temperatures.

How do I determine the size of a solar string?

The size of a solar string, or the number of panels you can have in a series, is determined by the specifications of your solar panels and the inverter you’re using, and the climate conditions where the panels are installed. Here are the steps: 1. Find Your Panel and Inverter Specs Check the spec sheets for your solar panels and inverters.

What is the minimum string size of a PV inverter?

The minimum string size, then, is 15 modules. The maximum string size is the maximum number of PV modules that can be connected in series and maintain a voltage below the maximum allowed input voltage of the inverter. The Module Voc_max is calculated using the coldest temperature when the modules produce the highest expected voltage.

How many solar panels can be connected in a string?

1. Calculating maximum string size The maximum number of solar panels you can connect in a string is determined by the maximum input voltage of your inverter or charge controller. You can find this value on the inverter datasheet. If the maximum input voltage of your inverter is exceeded on a cold day, the inverter can be damaged.

How do you calculate voltage across a string of solar cells?

When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.
