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 its 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 ($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.

Even when Chinese panel shipments fell 13% in May after a tax rebate removal, exports to the Philippines rose by almost a third.

Surge in inquiries

Philergy German Solar, a Manila-based ​installer, received more than 2-1/2 times the number of customer enquiries in the first five months of this year compared to last year.

At one point, it ‌fielded 3,000 ⁠inquiries a day, according to managing partner Jochen Staudter.

Customers are deciding to buy “much faster than before,” Staudter said. “Demand will continue to be driven by high electricity prices.”

In two years, distributed solar capacity could nearly triple to 3,500 megawatts (MW), matching the current size of the Philippines’ utility-scale solar fleet, as loan payback times shrink to 3.1 years from 4 years, said Alnie Demoral, analyst at energy think tank Ember.

Solar accounts for under 4% of national ​power consumption, government data shows.

Supply challenges

A weakening ​currency has compounded the increase ⁠in power prices because the Philippines relies on imported coal and gas to generate power.

That has pushed inflation to multi-year highs and slowed growth.

Manila entrepreneur Jason Porciuncula installed a 12-kilowatt system with battery storage in January.

As prices ​hit record highs in May, his monthly bill dropped to a fifth of last summer’s 21,000 pesos.

But ​it’s not all smooth ⁠sailing. Installations are lagging behind demand due to component hoarding, volatile equipment costs and inadequate quality checks, said Brenda Valerio, Philippines director at New Energy Nexus.

The government provides loans for solar of up to 500,000 pesos at 5% interest, below market rates. But it excludes private-sector workers.

Another deterrent: high upfront costs, ⁠usually above average ​annual household incomes of 353,200 pesos.

“The opportunity is real, but the upfront cost is ​often too high for a household or business, no matter how quick the payback time is,” Ember’s Demoral said.
