Soaring fuel costs driven by the Iran war are pushing Asian consumers toward rooftop solar power, creating a significant market opportunity for China as the world's largest provider of solar technology. The energy crisis has triggered a dramatic surge in solar installations across the region, with Chinese manufacturers positioned to capture the lion's share of new demand.
In the Philippines, which is in a national energy emergency, a survey of 20 local solar companies found a 70% increase in weekly installations and a six-fold jump in customer inquiries since the conflict began. Brenda Valerio of the nonprofit New Energy Nexus, which ran the survey, said, "This crisis is a driving force for solar," and, "People want solar and people want solar now."
China's Market Dominance
Chinese clean technology equipment exports hit a record high in March, according to energy think tank Ember, and worldwide interest in solar is increasing. Li Shuo, director of the Asia Society Policy Institute's China Climate Hub, said, "China really is, by far, leading this race," and called the renewable industry "a one-man show."
The Philippines, which relies heavily on Middle Eastern crude oil and liquefied natural gas, is among the most impacted Southeast Asian nations by the closure of the Strait of Hormuz. Local airlines are weighing fuel rationing. Public transport workers are receiving cash handouts. Gas and diesel prices also have shot up.
To conserve energy, government offices have shifted to a four-day work week and been told to keep air conditioning no lower than 24 degrees Celsius, or 75 degrees Fahrenheit. Oil and gas spikes during the first 60 days of the Iran war cost Filipino consumers, businesses and public institutions more than $600 million, the climate nonprofit 350.org estimates.
Consumer Response to Energy Crisis
Jaime Quemado, who recently bought a rooftop solar system in Manila, said, "When we got our energy bill after the Iran war broke out, we were very shocked. It was wow. It was a significant increase," and said there were growing concerns about potential power outages, which led him to look for an alternative energy source like "solar, which is very abundant here in the Philippines."
Customer interest in rooftop solar jumped from around 115 inquiries in February, before the start of the Iran war on Feb. 28, to more than 450 by mid-April, according to the New Energy Nexus survey. Valerio said solar groups must "ride this wave and take advantage of this momentum."
On two blisteringly hot days in Manila, EcoSolutions installers sweated through the set up of an 18-kilowatt rooftop solar system, which included 28 panels from major Chinese manufacturer LONGi and four batteries from Suzhou-based battery group Dyness. Richmond Reyes, EcoSolutions president, said, "The war has helped the solar industry really get its footing."
Joel Remegio of the Association of Solar Installers of the Philippines said the energy crisis is a "game changer" for the nation's nascent solar industry. Marissa Cerezo of the Department of Energy's Renewable Energy Management Bureau said clean technology, like rooftop solar, is quickly scalable because it is "accessible to all of us," and added, "This gives us the power to choose them."
Regional Market Expansion
Solar is being embraced across Southeast Asia. Indonesia set an ambitious target to install 100 gigawatts of rooftop solar by 2034, a leap from its current 1.3 gigawatts. Vietnam wants to install rooftop solar on at least 10% of public offices and homes nationwide by 2030. Thailand is considering new policies to give rooftop solar users a bigger bang for their buck by increasing the amount of surplus energy the national grid can buy.
Yu Sun Chin of the research group Zero Carbon Analytics said the energy crisis is incentivizing these decisions. She said, "It totally makes sense for policymakers to take another look at rooftop solar and see ways that they can save costs."
Online marketplaces and utility companies in the U.S. and across Europe also have recorded jumps in solar sales and inquiries since the Iran war began. Jan Rosenow, a professor of energy and climate policy at Oxford University, said, "Solar is definitely one of the easiest things people can do" to cut monthly electricity bills. He said the availability and affordability of rooftop solar make it the easiest clean technology solution given the higher expense for buying an electric vehicle or installing a heat pump.
Chinese Export Surge
Ember noted China exported 68 gigawatts worth of clean technology products in March, equivalent to Spain's entire solar capacity and double its February output. Ember found the Iran war is accelerating the world's energy transition. Exports to Africa hit 10 gigawatts, a 176% jump from February, with rapid growth in Nigeria, Kenya and Ethiopia. Exports to other Asian nations doubled to 39 gigawatts, including major increases to India, Malaysia and Laos.
Ramnath Iyer of the U.S.-based Institute for Energy Economics and Financial Analysis said the speed of the transition depends on whether world leaders "decide to go ahead with electrification and move away from fossil fuels."
Li said Chinese companies had an oversupply of solar panels and other equipment before the war, putting them in a prime position to capitalize on current demand. He said, "When it comes to the clean tech sector, China at this point in time is already so far ahead," and, "The current situation in Iran will help China cement its dominance."
Why This Matters:
The Iran war's disruption of global energy markets has created an unintended consequence: a massive acceleration in solar adoption that primarily benefits Chinese manufacturers. With Chinese companies holding an oversupply of solar equipment before the conflict and now exporting record volumes, Beijing is consolidating market dominance in a critical technology sector. For Asian consumers facing $600 million in additional energy costs in just 60 days in the Philippines alone, rooftop solar represents a market-driven solution to energy insecurity. However, the shift also raises questions about strategic dependence on Chinese technology at a time of heightened geopolitical tensions. The crisis demonstrates how supply chain vulnerabilities and foreign conflicts directly impact household budgets, driving individual consumers to seek energy independence through private investment rather than government intervention.
