Chinese solar manufacturers increase prices

Both solar cell manufacturers Longi and Tongwei have raised their prices. Tongwei raised the price of solar cells of various sizes by between 3 and 4 percent on Monday. Rival Longi followed suit on Tuesday, raising prices for wafers – a precursor to cells – by 3 to 4 percent as well. The price adjustment follows an increase in the cost of polysilicon of just over 15 percent over the past two months. Polysilicon is the base material for wafers.
