What permits a solar installation needs in the Philippines, and what changed in August
Ask this in a Facebook group and you get six answers, most of them confident and several of them now out of date. The rules for own-use solar moved in August 2026, and almost everything written about Philippine solar permits was written before they did.
Most people assume the size of the array decides what they have to file. What actually decides it is whether the system can push electricity back out to the grid. Settle that one question and the rest of the paperwork follows from it.
Three routes, and yours is one of them
Read down to the one that matches what you are planning. The first two come from Department Circular DC2026-08-0017, which the Department of Energy issued in August 2026 to cover solar that is for your own use and sends nothing back.
Route 1
A micro-solar system
Panels adding up to 1,000 watts of DC capacity or less, behind a factory-set grid-tied micro-inverter rated at 800 watts AC or less with automatic anti-islanding, connecting through an ordinary household outlet or circuit. The circular calls this a Micro-Solar System and sets those three numbers as the definition. Go past any of them and you are in the route below.
- Written notice to your distribution utility
- Required, on the form attached to the circular.
- Building permit from your local government
- Not required under the circular.
- Certificate of compliance from the ERC
- Not required under the circular.
Route 2
Any size, so long as nothing goes back out
Solar of any capacity, for your own use, fitted with a control or isolation mechanism that stops electricity reaching the distribution system. The circular calls this a Self-Generating Facility Zero-Export Solar System and splits it in two: connected to the grid but blocked from exporting, or standing on its own and not connected at all.
- Written notice to your distribution utility
- Required if the system is connected to the grid. An off-grid system that touches no distribution line does not need one.
- Building permit from your local government
- Required. If your local government checks the permit the building already has and finds it covers the work, you send a copy of that one instead of applying again.
- Certificate of compliance from the ERC
- Required, except where the system is for the own or internal use of a household, a clinic, a hospital or another medical facility. Most homes fall inside that exception.
Route 3
Exporting the surplus, and earning credit for it
The moment you want the electricity you do not use to go out to the grid and come back as credit, you are outside this circular and inside the net metering programme. That is an application to your utility, an agreement signed with them, an inspection and a meter change.
- Written notice to your distribution utility
- Replaced by a full application and a net-metering agreement with them.
- Building permit from your local government
- Required, under section 301 of the National Building Code.
- Certificate of compliance from the ERC
- Governed by the ERC rules for net metering rather than by this circular.
What your distribution utility is no longer allowed to ask for
This is the part that answers the question people actually type, which is whether the utility has to sign the job off before anybody climbs onto the roof. For a zero-export or micro-solar system the circular directs distribution utilities to make sure no administrative barrier stands in the way of the installation, and it names three of them: pre-installation clearances, technical permits and inspection fees.
It also stops them cutting your transformer or service drop capacity because you put solar in, so the grid stays behind you at full strength on the day the system goes down. A utility may still run a distribution impact study, at its own cost, for its own planning. What it may not do is hold up your installation while it does.
What the notification form asks for
One page, attached to the circular as Annex A, and it goes to the utility after the system is in.
- Your name, service address and account number.
- Which of the two it is, zero-export or micro-solar.
- Installed PV capacity in DC, and inverter capacity in AC.
- The date you installed it, and your signature under a declaration that it complies.
Two things to settle before you choose zero-export
Going zero-export buys you the lighter paperwork above. It costs you something, and it is worth knowing what.
- Surplus is simply lost
- A zero-export system generates less than it could on a bright afternoon, because the control mechanism holds it back rather than letting it out. If electricity does reach the grid from one of these, the circular treats it as non-compensated export: no credit, no offset, nothing on the bill. Keeping that mechanism working is your obligation, and letting it fail is a breach of the circular.
- You can change your mind later
- The circular tells distribution utilities to give technical guidance to anyone moving from a zero-export arrangement to net metering afterwards. Starting zero-export while you watch your own consumption for a year is a reasonable thing to do, and it does not shut the other door.
And one that is still only a bill
House Bill 10431, the proposed Sariling Kuryente Act, was filed in the House of Representatives on 29 July 2026. It would amend the Electric Power Industry Reform Act so that an end-user generating for their own use is not treated as a generation company. It would put a ten working day clock on an interconnection application, with approval deemed given if the utility lets that run out. And it would stop a homeowners association or a subdivision developer prohibiting an installation on property you control.
None of that is in force. It is a bill, it has not become law, and this page will keep saying so until that changes. Everything above it is already the rule.
What people ask us about permits
Do you need a permit to install solar panels in the Philippines?
For most households, a building permit from your local government, and that is the whole of it. A zero-export system for a household does not need a certificate of compliance from the Energy Regulatory Commission, and a micro-solar system inside the 1,000 watt limit needs neither the certificate nor the building permit.
If you want the surplus to earn credit on your bill, that is a separate application to your distribution utility under the net metering programme, and it carries an inspection and a meter change with it.
Do I have to ask my electricity provider before I install?
Not for a zero-export or micro-solar system. The circular directs distribution utilities to run a notification process after installation, and tells them not to impose pre-installation clearances, technical permits or inspection fees as a condition of putting the system in.
You do still have to notify them, on the form attached to the circular, and it asks for your account number, the DC capacity of the panels, the AC capacity of the inverter and the date you installed it.
What counts as micro-solar?
Three limits at once. The panels total 1,000 watts of DC nameplate capacity or less. The micro-inverter is factory-set and puts out 800 watts AC or less, with an automatic anti-islanding disconnection. And the whole thing connects through a standard household outlet or circuit, wired to the Philippine Electrical Code.
Miss any one of the three and the system is not micro-solar, whatever it was sold as.
My subdivision says I am not allowed to put panels up. Can they do that?
The circular tells the Department of Energy to work with the department overseeing homeowners associations, condominium corporations and building managements on getting these systems onto balconies, windows, roofs and other available areas, and it carves out only established proof of structural risk or a direct threat to public safety.
That is a direction to a government department rather than a right you can wave at your association today. The bill described further down this page would go further and stop an association prohibiting an installation outright, but it is a bill.
Why does everyone give a different answer about permits?
Because the local government half of it is still being settled. The circular gives the Department of Energy sixty days from the date it took effect to agree uniform guidelines with the Department of the Interior and Local Government for how local government units apply it, and gives distribution utilities thirty days to update their citizens charters.
Anything written before August 2026 describes the arrangement that existed before all of this, and that is most of what a search turns up.
Is it different in Pampanga?
The circular is national and binds every distribution utility, so the answer to the export question is the same in San Fernando as it is anywhere else. The building permit is your own municipality or city, and offices differ in what they hand you across the counter and how long they take.
Tell us which town you are in and who bills you for electricity, and we will tell you what those two will ask for.
Where to read next
Paperwork is one of four things that move what an installation costs, and the net metering route has a page of its own.
Tell us which of the three yours is and we will tell you what it needs
Or tell us what you are trying to achieve and we will work out which of the three it ought to be. Your town and whoever bills you for electricity is enough to start.
Tell us the property and what you are trying to cut, and you will get a written answer with a size and a next step. No visit is booked and nothing is charged for asking.
