From Energy Yield to Real-Time Performance: A New Metric for PV Project Success
Marcel Suri explores the datasets that will help improve the accuracy of PV output estimation and drive better performance.
The size of PV projects and increasingly complex market conditions in which they operate demand greater sophistication in plant performance modelling.
For two decades, solar energy project design and evaluation has centred around annual energy yield as the most important metric.
Defined as the theoretical energy production of a PV plant under typical weather and system assumptions, energy yield is a concept that is largely focused on maximising the quantity of energy produced by a solar power plant per year.
However, as the solar sector evolves in response to real-time market demands, volatile pricing and increasingly complex grid requirements, this once-reliable metric is no longer sufficient on its own.
Author's summary: New metrics are needed for PV project success.
