The cost of photovoltaic solar panels (PV) has risen by more than 40% in the past 18 months to $27-28 cents per watt, due to a rise in polysilicon prices. This is mainly caused by disruptions in the value chain activities of solar module manufacturing in China and an increase in the cost of polysilicon, a critical material for module manufacturers. Rising cell and module prices have contributed to the cost constraints facing solar power manufacturers, even as supply chain concerns continue to ease.
