The China Photovoltaic Industry Association (CPIA) is calling on local solar power developers not to exacerbate the surging costs of raw materials by stockpiling polysilicon and other materials for manufacturing solar components.

Companies in the solar power industry, not only in China but all around the world, have been flagging soaring costs for raw materials since the start of this year. The rise in costs, after years of decline, threatens to delay solar installations worldwide.

“At present, some photovoltaic companies have drastically reduced operating rates, cut production or even suspended production,” CPIA said on Thursday, as carried by Reuters.

Some companies have reduced or suspended production, and some orders are not being met because of the surging costs and imbalances in the supply chain, the association added. (RT)
