According to the statistics of authoritative institutions, the average annual growth rate of global photovoltaic modules has reached 30% in recent years, and the photovoltaic industry has become one of the fastest growing emerging industries in the world.

Photovoltaic power generation needs sunlight, but it can't generate electricity in the evening and rainy days. Therefore, batteries are needed to store electricity for it. Due to the limited power, capacity and service life of lead-acid batteries, vanadium batteries have high energy cycle efficiency and electrolyte can be recycled. With ultra-high cost performance, they are a powerful reserve force in the photovoltaic power generation industry.
