Polysilicon prices jumped by the most in eight months with maintenance scheduled at key facilities, threatening to raise the cost of solar panels as clean energy demand soars.

The average cost of the most expensive grade of polysilicon rose 4.8% to 286.3 yuan ($42.7) a kilogram on Wednesday, according to a statement from the China Silicon Industry Association. It’s the highest price for the material since late 2011.
