PH Solar & Electricity News — Week of August 31, 2026
TL;DR
Ember now puts Philippine rooftop solar payback at 3.1 years, down from about four, and panel imports rose to $483 million in 2025. A Pulse Asia survey found nine in ten Filipinos want government action on rooftop solar affordability, while homeowners report net metering taking four to six months against the DOE mandated ten working days. The Visayas grid ran a seven-hour red alert on Tuesday and Mindanao is now on yellow alerts too. Geothermal drew a ₱10-billion derisking facility with 17 firms queuing, and First Gen contracted 25 MW of it to Alliance Global.

Ember puts rooftop solar payback at 3.1 years as panel imports climb
Philstar reports Ember research putting household solar payback at 3.1 years, down from about four. Panel imports reached $483 million in 2025 from $365 million, 98 percent from China, and Pulse Asia found nine in ten Filipinos want government action on rooftop solar affordability. Two homeowners interviewed paid ₱350,000 for 8 kWp and ₱200,000 for 5.8 kWp including ₱60,000 of net metering cost.
What this means
That 3.1-year figure lands inside our own range rather than contradicting it. At the ₱1,300 per kW per month saving this site publishes, a system at ₱45,000 per kW pays back in 2.9 years and one at ₱55,000 in 3.5. Worth noticing what the two homeowners did to get there: both sourced equipment themselves. ₱350,000 for 8 kWp is ₱43,750 per kW, just under the bottom of our installed band, and the 5.8 kWp system works out lower still. Self-sourcing is a real lever, and it is also where the warranty and permit risk sits.
Policy
Net metering is taking four to six months against a ten-day mandate
The same report carries homeowner accounts of net metering applications running four months in one case and up to six in another, against the DOE circular that gives distribution utilities ten working days to approve or reject and local governments three working days to issue electrical permits. Energy Secretary Sharon Garin responded by asking consumers to report anyone causing delays.
What this means
This is the gap between the rule and the queue, and it changes how you should plan. The ten-day timeline is real policy, but budget for months and file early rather than assuming the system is exportable the week it is switched on. Until the meter is approved, everything you generate and do not use is given to the grid for free, which quietly lengthens the payback the previous item just shortened. Keep your paperwork dated and keep a record of every submission, because the escalation route the Secretary described needs evidence.
Grid
Visayas red alert runs seven hours Tuesday as Mindanao joins the yellow alerts
NGCP put the Visayas grid on red alert from 2 p.m. to 9 p.m. on Tuesday, with yellow alerts either side, and Mindanao on yellow from 1 p.m. to 8 p.m. The previous day Visayas ran red from 5 p.m. to 10 p.m. and Mindanao yellow from 6 p.m. to 9 p.m., which Inquirer attributed to the unavailability of some large coal plants. Supply is now described as tight across both grids.
What this means
Fifth consecutive week for the Visayas, and Mindanao has joined it. Look at Tuesday window: 2 p.m. to 9 p.m., the longest yet. A rooftop array covers the first half of that and produces nothing after about six. The tail is the part that needs a battery, and it is also the part that decides whether your evening is bearable. If you are sizing storage in Cebu, Negros, Panay or Davao, size it against a three-hour evening gap rather than a full night, which is a much cheaper pack.

Policy
Geothermal draws a ₱10-billion derisking facility and a 25 MW corporate deal
The DOE says 17 power firms are queuing for the ₱10-billion Philippine Geothermal Resource Derisking Facility, which covers up to half of drilling costs through convertible loans that become grants if exploration fails. Separately, First Gen contracted 25 MW from its Bacon-Manito geothermal plants to Alliance Global, serving Megaworld townships, malls and Emperador distilleries.
What this means
Geothermal is the one renewable that runs at night, which is exactly the gap the grid alerts above expose, and both stories show why it is slow: a single well costs six to eight million dollars and the government is subsidising half the drilling risk to get more drilled. Nothing here reaches your bill this year. The First Gen deal is more immediately instructive, because contracting your own renewable supply directly is a route open to large users under the Green Energy Option Program, not to households.
