6 FAQs about [Load following of photovoltaic inverters]

Why are solar developers increasing inverter loading ratios?

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.

How does inverter loading ratio affect a fixed tilt photovoltaic system?
