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.
String sizing in a PV system involves determining the optimal number of solar panels (modules) that can be connected in series (a string) and parallel (multiple strings). Proper string sizing ensures: The system operates within the voltage and current limits of the inverter. Maximized efficiency and performance.
Several factors influence string sizing in PV systems: Module Characteristics: Voltage, current, power, and temperature coefficients. Inverter Specifications: Minimum and maximum input voltage, current, and MPPT range. Environmental Conditions: Temperature variations affecting module voltage. System Configuration: Grid-tied or off-grid setup. 3.
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!
