Thus, the optimal number of modules per string is 16. Unlock the full potential of your solar power system! By leveraging the rated operating voltage parameters provided by inverter manufacturers, you can effortlessly determine the optimal number of modules per string.
The design of solar panel strings needs to satisfy two conditions simultaneously: The maximum open-circuit voltage of the series-connected photovoltaic modules should be lower than the inverter's maximum input voltage. The MPPT voltage of the series-connected photovoltaic modules should fall within the inverter's MPPT voltage range.
Considering the local environmental temperature conditions, the inverter can connect 6 to 19 modules per string. Principle: The closer the inverter's Vmppt voltage is to the rated operating voltage, the higher the efficiency and the better the power generation yield.
When number of modules are connected in series and parallel combination it is known as PV array and the effective output of a PV array is determined based on the parallel/series combination of PV modules. Typically, PV array is sized based on inverter input voltage considerations.
Typically, PV array is sized based on inverter input voltage considerations. In case of a typical 1000 V DC inverter voltage, a string is formed by connecting about 20 modules in series. In recent years the inverters are available with a 1500 V DC inverter voltage and string sizing is done by connecting about 28 or 30 modules in series.
The maximum number of modules in series can be as much as 11. Now we have all the parameters that we need to design a system which will not go over the maximum input voltage of the inverter at record lows and will meet the minimum start-up voltage of the inverter where cell temps are at their highest.
