Extended Data Fig. 1: Sensitivity and convergence of results based on parameter settings.

Fraction of solar power variance driven by model differences (\({F}_{m}\)) for different values of psample size – i.e., the number of scenario-climate category pairs drawn in each sample (per unique scenario-climate category combination). Confidence intervals show the range of values reached with resampling 100 times (individual samples are shown in dots). In the main results of this paper, we also resample (presample = 100) times and take the average, and we use psample size = 3,000.
