How-To Determing Solar String Size (Examples
Determine your solar string size by considering panel & inverter specs, temperature effects, and calculating maximum string size. Consult a professional for accuracy.
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.
Here are the results we calculated: This inverter has 2 MPPT trackers, so a total of 2 strings can be connected to the inverter. We know that there can only be 13 modules maximum installed. We can have one MPPT with 6 modules in a string and the other at 7 modules in a string. Check out UpTop Solar String Sizing Tool that does this for you!
PV string inverters convert the direct current (DC) generated by solar panel strings into alternating current (AC) that can be fed into the electrical grids, which are commonly used in homes and businesses, including rooftops, carports, ground mounts, and tracker systems.
Calculate the Maximum String Size Take your inverter's maximum DC input voltage. Divide it by your adjusted Voc. This gives you the maximum number of panels you can have in a string. For instance, if your inverter's max input is 1000V: You can't have a part of a panel, so round down to the nearest whole panel.
