Why is the cost of solar street lights rising?
2026-04-10
If you’re involved in the renewable energy or urban lighting sector, you’ve probably noticed a recent rise in the prices of solar street lights. This isn’t a random fluctuation—it’s the result of a “perfect storm” in the global supply chain.
Here are the 3 main reasons driving this trend:
1️⃣ Geopolitical tensions and logistics crises: The conflict in Iran and the consequent blockade of the Strait of Hormuz have directly impacted the sector. On one hand, global maritime freight costs have risen and slowed down. On the other, the supply of petrochemical by-products essential for manufacturing solar modules—such as EVA encapsulant film and materials for back sheets—has been disrupted.
2️⃣ Rising costs of Lithium Iron Phosphate (LFP) cells: Batteries are the core cost component of a solar street light. The current price increase is not just driven by demand, but also by supply constraints: Zimbabwe’s ban on raw lithium exports, reduced production in Australia, and a production cut strategy by major Chinese manufacturers to maintain market prices.
3️⃣ End of China’s export tax incentives: Since April 2026, a new tax policy in China has taken effect. Export tax rebates for batteries dropped from 9% to 6%, and for photovoltaic components, they were drastically reduced to 0%. The profit margin that previously absorbed some of the cost now translates directly into cost pressure for buyers.
Conclusion / Call to action: In this landscape, optimizing technical design, planning purchases in advance, and diversifying suppliers are no longer optional—they are strategic necessities to keep renewable lighting projects competitive.
How is this situation affecting your current projects? Do you think prices will stabilize in the second half of the year? I’d love to hear your thoughts in the comments!
