Customer ServiceChina’s pursuit of photovoltaic (PV) power, particularly rooftop installations, addresses energy and ecological challenges, aiming to reduce basic energy consumption by 50% by 2030. The northwest region, with its solar potential, is a focal point for distributed PV growth, which has already exceeded 50% of the energy mix by 2021.
Solar energy is the most common, cheapest, and most mature renewable energy technology. With solar photovoltaics taking over recently, an in-depth look into their supply chain shows a surprising dependency on the Chinese market from the raw materials to the assembled PVs.
China has already made major commitments to transitioning its energy systems towards renewables, especially power generation from solar, wind and hydro sources. However, there are many unknowns about the future of solar energy in China, including its cost, technical feasibility and grid compatibility in the coming decades.
In addition, China is responsible for the processing of rare earth elements that are mined abroad. China worked hard to maintain its position as a leader in the production of assembled PVs and their parts. The country has also majorly invested in installed capacities. In the span of 25 years, China was able to install 393 GW of solar PV alone.

In response to the pledge, the country's solar panel installation pace is expected to accelerate (Wang et al., 2019). Therefore, China will be the highest consumer of critical materials needed in solar panels, and this scenario will increase the supply limitations on critical materials to the rest of the world.
