How do I calculate PV string size & voltage drop?

The easiest and fastest way to calculate PV string size and voltage drop is to use the Mayfield Design Tool. Our web-based calculator has data for hundreds of PV modules, inverters, and locations so you don’t have to look up datasheets nor do manual calculations. You can access the Mayfield Design Tool for free on our website here.

How to design a solar PV system?

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.

What is a photovoltaic string?

The set of photovoltaic modules connected in series is what is known as a PV string, and therefore the formation of a photovoltaic string is crucial for the production of solar energy.

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.

How do PV panels work?

The series of connections of such PV panels, in electrical terms, mean that electric current flows through one PV module and then through the next, and so on through the string assembly in a unitary manner. On the other hand, the total voltage of the photovoltaic string, is the sum of the voltages of each individual module.

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.
