Installers typically follow one of three common solar inverter sizing ratios:Aggregate panel wattage x 1.25Aggregate panel wattage x 1.3Aggregate panel wattage x 1.35.

The DC-to-AC ratio, also known as the Array-to-Inverter Ratio, is the ratio of the installed DC capacity (solar panel wattage) to the inverter’s AC output capacity.

The US Energy and Information Administration (EIA) states, “for individual systems, inverter loading ratios are usually between 1.13 and 1.30.”.

The ratio of these two capacities is referred to as the inverter loading ratio (ILR). The 2021 ATB assumes current estimates, and future projections use an inverter loading ratio of 1.34.
