The PV module capacity and solar inverter capacity ratio are commonly referred to as capacity ratio. Reasonable capacity ratio design needs to be considered comprehensively in the light of the specific project.
However, the authors recommended that the inverter capacity and PV array power must be rated at 1.0:1.0 ratio as an ideal case. In the second study, B. Burger tested the two types of PV panel technologies to match the inverter Danfoss products with the PV array-rated power in sites around central Europe.
The suggested ratio ranged from 1.06 to 1.11 for the Thin-Film PV plant . According to Solar , the inverter might be sized between the PV array power and active power of the inverter ratings (0.80 to 0.90).
In the literature, there are many different photovoltaic (PV) component sizing methodologies, including the PV/inverter power sizing ratio, recommendations, and third-party field tests. This study presents the state-of-the-art for gathering pertinent global data on the size ratio and provides a novel inverter sizing method.
InMalaysia, the typical derating factors for the PV to inverter power size ratios utilized are 1.00 to 1.30 Thin-Film and 0.75 to 0.80 for the c-Si PV type .
For a broad range of inverter sizing values from 0.80 to 1.10, the adjustment dimensioning factor (DF) may be used according to the specific location in their simulation . However, as larger inverters cost more per watt, the optimal ratio must not be larger than 20% of the power rating of the PV array.
