The report argues that China can sustain roughly 22% ESS installation CAGR through 2030, while overseas demand, particularly Europe, remains a major growth driver. It views reported weak 1H26 China installation data as distorted by reporting lags and back-end-loaded project delivery rather than a demand reversal.
