One of the most critical parameters in solar engineering is the DC and AC ratio, often referred to as the Inverter Loading Ratio (ILR).

This can be calculated by taking the power rating of the array (KW DC) divided by the power rating of the inverter (KW AC). As others have stated, the same size solar array would likely generate the same

Because the PV array rarely produces power to its STC capacity, it is common practice and often economically advantageous to size the inverter to be less than the PV array. This ratio of PV to
