Top power distributor Meralco has raised prices by 10% since the Middle East conflict began in late February. Now, a median household spends around 12% of monthly income on electricity, assuming it consumes 200 kilowatt-hours, approximately the monthly average for three people.

The Philippines is one of the few countries in Southeast Asia with barely any power subsidies, and its residential power prices are the highest in the region. Only Singapore comes close, but its citizens' average purchasing power is nearly 13 times higher.

Adrian Sabatera, a 39-year-old software engineer, thought about getting solar for years but found it too ⁠costly. That changed as costs came down and electricity prices kept rising.

"I wouldn't be shocked if a third of the middle-class population eventually finds their way to this setup," Sabatera said after recently pulling the trigger on a 570,000 peso (US$9,300) installation at the Manila house he shares with three others.

The rooftop solar rush has resulted in $407 million in panel imports in the three months through May, a 145% increase from a year earlier, according to trade data from China, which accounts for most global supply.
