Rystad Energy estimates that 56% of projects — or 90GW of solar capacity — are threatened by commodity price inflation and supply chain bottlenecks.
Costs for solar PV modules “have surged from below $0.20 per watt peak (Wp) in 2020 to between $0.26 and $0.28 per Wp in the second half of 2021 – a near 50% increase in a year,” the report notes.
A 300% increase in the cost of polysilicon is driving the module cost surge, while the costs of raw materials have also rapidly increased since the beginning of last year.
