>>It is important to note that within Germany’s generation data, Ember’s analysis has identified an unusual trend of declining solar irradiance-adjusted performance over the past several years. We do not yet have a definitive explanation for why this is, but it could be related to challenges in measuring behind-the-meter solar generation, exacerbated recently by high levels of residential battery storage. Regardless of the cause, it is possible that there is under-reporting of German solar generation.
