A string consists of solar panels wired in a series set into one input on a solar string inverter. If you have two or more solar panels wired together, that is a solar / PV array. String sizing refers to how many solar panels can and should be wired to an inverter for best results.
A solar panel or PV module is made up of several cells, while multiple solar panels wired in a series or parallel is called a solar array. A string consists of solar panels wired in a series set into one input on a solar string inverter. If you have two or more solar panels wired together, that is a solar / PV array.
Rounding up, the minimum string size is 7 panels. Understanding the intricacies of solar PV strings, including how to calculate the number of panels per string and the importance of startup and maximum DC voltage range, is essential for optimising your solar power system.
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.
The design is known as a solar array. A string consists of solar panels that are wired in a series set to one input on a solar string inverter. In case two or more solar panels are wired together, that is a solar / PV array. String sizing depicts how many solar panels can be wired to an inverter to obtain the best results.
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.
