Solar plants typically install more panel capacity relative to their inverter capacity

U.S. Energy Information Administration ------- A solar photovoltaic (PV) system’s panel capacity is often reported in direct current (DC), while operating capacity in the United States is reported as it is delivered to the grid in alternating current (AC). For economic and engineering reasons, capacity values reported in DC typically are 10% to 30% higher than those reported in AC capacity. This ratio is often referred to as the inverter loading ratio (ILR). At the end of 2016, the United States had 20.3 gigawatts (GW) AC of large-scale photovoltaic capacity in operation with a DC module rating of 25.4 GW, resulting in a capacity-weighted average ILR of 1.25. For individual systems, inverter loading ratios are usually between 1.13 and 1.30. To learn more click on the picture below to read the article.
