China's solar power industry is entering a mature phase of stable pricing and high-quality manufacturing, following the recent removal of a key export tax rebate, which ends a prolonged era of volume-driven price wars and forces weaker, subsidy-reliant manufacturers out of the market.

Following the removal of a key value-added tax rebate for solar exports starting April, industry insiders and market analysts observe that a profound structural shake-up is actively underway.

The policy shift is acting as a powerful catalyst, forcing weaker, subsidy-reliant manufacturers out of the market while accelerating a much-needed return to long-term value, they say.

"This policy marks a critical turning point for the entire industry," noted Chen Jiahui, a senior solar market analyst from Shanghai Metals Market, a metal information provider in China.
