Summary: The measurement of near real-time national solar PV electricity output is crucial for managing electricity systems. Currently, national PV output is indirectly measured by upscaling the output from a sample of reference PV systems using an estimate of the national capacity. However, there are uncertainties in these measurements, particularly in the capacity error. To improve accuracy, nations must develop a comprehensive approach to PV system registration and explore alternative methods for estimating PV capacity.
