Why now
- Rising electricity demand driven by AI workloads and data center growth pressures solar supply chains.
- Commercial-scale perovskite-silicon manufacturing is transitioning from lab to market readiness.
- United Solar’s Oman factory recently began production, marking a milestone in polysilicon capacity expansion.
Why it matters
- Improved solar panel efficiency can reduce land and balance-of-system costs for utility-scale projects.
- Expanding domestic manufacturing capacity enhances energy security amid rising electricity demand.
- Increasing polysilicon production outside China diversifies global solar supply chains.
