-- European household demand for rooftop solar has more than doubled since the outbreak of the Iran war in late February, according to a Reuters analysis on Thursday.
The Iran war has propelled oil, gas, and electricity prices to record highs, forcing a rapid shift toward cheaper, localized alternatives to reduce exposure to extreme market volatility.
This surge provides a vital turnaround for a technology that accounts for one-third of Europe's power capacity but saw a decline in new installations last year due to the expiration of various support schemes, as per the report.
Industry data from Germany, Britain, and the Netherlands indicate that homeowners are increasingly moving beyond simple panel arrays, instead investing in integrated systems that include batteries.
These full-stack systems allow surplus power to be stored and utilized later, maximizing self-sufficiency, it added.
According to the report the current momentum is being further bolstered by upcoming legislative changes, such as Germany's revised renewable energy law.
Despite the lack of full 2026 data, the reported pickup in demand suggests that the war has effectively transformed residential solar from a subsidized luxury into a critical tool for energy security.
