Deep Dive: Solar CUF Statistical Analysis
This page presents a statistical deep dive into a representative solar capacity utilisation factor (CUF) profile. The analysis is based on a reduced-form 288-hour structure (12 months × 24 hours), constructed to illustrate seasonal and diurnal availability patterns.
The objective is to demonstrate analytical capability rather than produce forecasts. No user inputs are involved, and all results are deterministic.

Intra-day CUF Variability (Ratio)
Unlike wind generation, solar CUF includes extended night-time periods with zero availability. As a result, ratio-based intra-day variability metrics involve division by zero and therefore evaluate to infinity, and are not reported.
