A scientific paper published this morning by researchers at the Abu Dhabi Institute of Materials has prompted emergency orders to shut down at least 6.7 gigawatts of utility‑scale solar capacity across the Gulf Cooperation Council (GCC) and Maghreb, triggering an immediate market rout that wiped about $48 billion off the market value of publicly traded regional energy and infrastructure companies.
National grid operators from Abu Dhabi to Rabat announced rolling inspections after the study said a widely used polymer laminate — marketed under several trade names across module makers — breaks down rapidly in high‑UV, high‑salinity desert coastal conditions, causing panel delamination, tracker corrosion and sudden array fires. Insurers have paused new cover for large solar projects pending review.
What the paper found
The paper, authored by a seven‑person team led by Ece Özberk, reports laboratory and field tests showing that a polymer additive developed in the early 2020s begins forming conductive microgels when exposed to cycles of ultraviolet radiation above 800 W/m2 and airborne chloride concentrations typical of Gulf coastal sites. In field trials the team says affected modules lost up to 72% of rated output within 18 months and in several cases emitted heat signatures consistent with internal arcing.
"We did not set out to alarm policymakers; we were testing durability under real regional stressors," said Ece Özberk, the paper's lead author and a materials scientist. "Our results show a failure mechanism that accelerates performance loss and, in some configurations, creates a fire risk in less than two years — far shorter than the 15–25‑year lifespans investors assume."
Our region built its energy transition on assumptions that now look optimistic at best.

Markets and immediate consequences
Stock exchanges in Dubai, Riyadh and Casablanca suffered sharp selloffs in firms exposed to construction, operation and insurance of large solar parks after trading opened. DesertPower PLC, SaharaSun Holdings and GulfTrack — three regional builders and operators named by analysts as most exposed — saw combined market capitalisation fall by roughly $33 billion before circuit breakers slowed trading. Two major reinsurers, GlobalShield Re and Meridian Underwriting (both fictional composites), told clients they were pausing new large‑risk policies until independent testing completes, industry sources said.
Governments moved quickly. Renata Basile, the energy minister of an oil‑producing state that owns significant renewable stakes via its sovereign investment arm, convened an emergency cabinet meeting and ordered a 72‑hour moratorium on grid connections for new solar plants. "We will not jeopardise public safety or the grid's integrity," Basile said. Maida Hutapea, chief executive of DesertPower PLC, said her company had taken 1.2 GW offline voluntarily and was reallocating diesel‑fired capacity to keep supply stable while technicians inspect arrays.
Banks and developers now face a race to re‑test equipment, renegotiate project finance terms and seek clarity from module makers. Industry consultants estimated a worst‑case replacement and remediation bill of $18–35 billion across the region if the polymer is confirmed to be the root cause and retrofits are required. Market analysts warned that, if inspections extend past the winter demand season, power costs could rise across parts of the Levant and North Africa, increasing fiscal pressure on governments that have subsidised electricity.
Regulators said they aim to publish interim test protocols within 72 hours and to form a joint technical taskforce with EU and US laboratories. For developers, the immediate question is whether warranties issued by module manufacturers — many of them global suppliers that use the contested laminate — will cover remediation or whether costly replacements will fall to utilities and taxpayers. "This will define the next decade of our energy transition," said Chelsie Mante, a fund manager in Abu Dhabi who manages renewable infrastructure portfolios. "If warranties fail, confidence and capital will flee projects that were supposed to lower bills."
