Government solar and energy storage projects tend to prefer factory-based suppliers due to their strong focus on public fund security, long-term operational stability, and system risk controllability. Compared with trading or purely integrative companies, factory-based suppliers offer clear advantages in manufacturing capability, continuous supply, quality consistency, regulatory compliance, system integration, and long-term service support, making them better suited to meet the core requirements of government-led projects.
