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.
N = Max input voltage (1000 V)/49.7 Volt = 20.12 (always round down) The number of solar PV panels in each string must not exceed 20 modules Besides, at the highest temperature (location dependent, here 35℃), the MPP voltage VMPP of each string must be within the MPP range of the solar power inverter (160V–950V):
Thus, the output string will have 185V and 10.5A. Voltage is inversely proportional to temperature. The temperature coefficient of voltage, typically -0.3%/°C, must be considered. If the temperature drops to 10°C, the voltage increases as: Ensuring this voltage does not exceed inverter limits is critical. 2. Parallel Connection of Solar Panels
Simply divide the inverter's maximum system voltage rating by the open circuit voltage (Voc) of the module used and you're good. Well, that does get you in the ballpark, however, you could be at risk of over-sizing or under-sizing the number of modules in a string depending on where you are located in the world.
