Therefore, the capacity of a PV system is rated either in MW DC via the aggregation of all modules' rated capacities or in MW AC via the aggregation of all inverters' rated capacities.
Solar plants typically install more panel capacity
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).
Understanding DC/AC Ratio
The maximum AC power the system can deliver is limited by the inverter’s rated capacity, which is typically lower than the DC capacity of the solar panels. This intentional
SaurEnergy Explains
In a PV system, the rated capacity can be reported based on either all its modules or all its inverters. PV modules are rated under standard conditions and generate DC energy, while inverters convert DC to AC
What's the difference between AC and DC in solar?
Explore the differences between AC and DC solar panels, direct vs. alternating current, and the nuances of electricity flow in solar systems.
The Ultimate Guide to DC/AC Ratio and Inverter Loading
DC/AC ratio, also called inverter loading ratio (ILR), is the array’s STC power divided by the inverter’s AC nameplate power. ILR = P DC, STC / P AC, rated. A higher ILR
Why is my PV module rating larger than my inverter rating?
Every PV system has a DC:AC ratio, regardless of the architecture. Many inverters have DC:AC ratio limitations for reliability and warranty purposes. Enphase microinverters have no DC:AC
Best 6 Key Insights into DC and AC Ratio for Solar
The DC and AC Ratio (also called Inverter Loading Ratio – ILR) is the ratio between the total installed DC capacity of solar panels and the AC capacity of the inverter.

Understanding DC/AC Ratio
At first glance, it may seem like the inverter is undersized and thus a limiting factor in the system creating power, but it actually a healthy ratio of PV power to inverter power.
What Is PV Capacity and How Is It Calculated?
