For example, it is typical to see solar projects with 1.3 MW of PV panels per 1 MW of inverter capability. This oversizing of the PV panels in relation to the inverter size will maximize the total energy output of the system throughout the year, particularly during months with reduced solar irradiation.

This study proposes a statistical analytic method for collocating a PV power plant and utility-scale energy storage system (UESS) to minimise clipping losses. The novelty …
Hourly level solar data are insufficient to fully capture the magnitude of clipping. Due to decreasing solar module prices, some solar developers are increasing their projects'' inverter loading ratio (ILR), defined as the ratio of DC module capacity to AC inverter capacity. In this study, we examine the operational impacts of this trend.
While most utility-scale solar-plus-storage plants at year-end 2019 had an inverter loading ratio (ILR) of 1.3, the study said that examples of DC-coupled hybrid systems with higher ILRs are increasing. As the amount of solar increased on California''s grid, the wholesale value of solar generation from a fixed-tilt system without storage fell 39%.

Determine how much energy is delivered for each increase in inverter loading ratio. For example, if the total energy delivered for a 1.6 inverter loading ratio is 254,400 MWh and for a 1.7 inverter loading ratio is 269,600 the marginal change in energy delivery is 269,600 MWh - 254,400 MWh = 15,200 MWh.
