The rules that govern a Philippine rooftop, and when each of them arrived
Three things changed in 2026 and one of them expires with the emergency that created it. Most of what a search returns describes the arrangement before any of that, which is how a homeowner ends up filing for a permit the rules stopped requiring in August.
Seven instruments below, each with what it changed, whether it still stands, and how it was sourced. 2 were read in full, 1 is quoted by a government answer, 3 rest on a named report, and 2 could not be opened at all. The last two say so rather than borrowing somebody else's summary.
How each row was sourced
A register is only worth what its weakest row is worth, so every row says which of these it is rather than presenting them all as equal.
- Read in full
- The instrument itself, read from its own document.
- Quoted by government
- A government answer that quotes the instrument verbatim.
- Named report
- A named news report on a stated date. The instrument itself was not reachable.
- Not reached
- Neither the instrument nor a government quotation of it could be opened.
The register
Oldest first. The two 2026 circulars are the ones a household notices.
2008
Republic Act 9513
Renewable Energy Act of 2008
Quoted by government
- Status
- In force
- What it changed
- The statute everything else hangs off. It creates the net metering programme, and its Chapter VII sets out the fiscal incentives. Section 15(g) zero-rates the sale of power generated from renewable sources, and entitles RE Developers to zero-rated VAT on purchases needed to develop, construct and install their plant facilities.
- How this row was sourced
- Quoted verbatim by the Department of Energy answering a Freedom of Information request on 10 October 2022, tracking number DOE-717074777888. The question was whether a household is zero-rated. The answer quoted the developer wording and referred the asker to the Bureau of Internal Revenue.
2013
ERC Resolution No. 09
Series of 2013, the net metering rules and interconnection standards
Not reached
- Status
- In force
- What it changed
- Turns the statute into a programme: who qualifies, the 100 kW ceiling, the agreement with the distribution utility, and the technical standards a connection has to meet.
- How this row was sourced
- Not reached. The Energy Regulatory Commission site refuses an automated request and holds the challenge open rather than clearing it. The copies mirrored elsewhere are scans with no text layer, and one turned out to be a presentation about the rules rather than the rules. Nothing on this page is claimed from it.
Early 2026
Executive Order 110
Series of 2026, declaring a State of National Energy Emergency
Named report
- Status
- In force, and it is the condition the next row depends on
- What it changed
- Declares the emergency. On its own it changes nothing about a rooftop, but the fast net metering timetable below exists only for as long as this declaration does.
- How this row was sourced
- BusinessMirror, "DOE fast tracks net metering applications", 2 April 2026.
April 2026
Joint Memorandum Circular 001
Series of 2026, of the DOE, the DILG and the DPWH
Named report
- Status
- In force for the duration of the emergency above, unless revoked sooner
- What it changed
- Cuts the distribution utility or cooperative to ten working days to process a net metering application including technical rectifications, non-extendible, from twenty. Gives local government units three working days on the related permits, where before there was no single period. Adopts a no additional requirements policy for the permits it covers, and deems an application approved if nobody acts in time.
- How this row was sourced
- BusinessMirror, same report, 2 April 2026.
August 2026
Department Circular DC2026-08-0017
Policy Guidelines for Self-Generating Facility Zero-Export Solar Systems and Micro-Solar Systems for Own-Use
Read in full
- Status
- In force
- What it changed
- The one that matters most to a household. Creates two categories for solar that exports nothing. A micro-solar system, meaning panels to 1,000 W DC behind a factory-set micro-inverter to 800 W AC through an ordinary outlet, needs no building permit and no certificate of compliance. A zero-export system of any size needs a building permit, and a certificate of compliance except where it serves a household, a clinic, a hospital or another medical facility. It also forbids the utility to impose pre-installation clearances, technical permits or inspection fees.
- How this row was sourced
- The circular itself, read in full from the Department of Energy content server, section by section including its Annex A notification form.
Circulating in 2026
ERC draft amendment
Draft Amended Net-Metering Interconnection Standards
Not reached
- Status
- A DRAFT. Not in force, and a draft is not a rule
- What it changed
- Would amend the 2013 interconnection standards. What it would change is not stated here, because the document could not be opened.
- How this row was sourced
- Not reached, behind the same wall as the 2013 resolution. Its existence is visible because it appears in search results from the regulator’s own domain; its contents are not claimed.
Filed 29 July 2026
House Bill 10431
The proposed Sariling Kuryente Act
Read in full
- Status
- A BILL. Not law
- What it changed
- Would amend the Electric Power Industry Reform Act so an end-user generating for their own use is not treated as a generation company, put a ten working day clock on interconnection applications with approval deemed given if a utility lets it lapse, and stop a homeowners association or subdivision developer prohibiting an installation on property the owner controls.
- How this row was sourced
- The bill itself, e-filed 29 July 2026 in the Twentieth Congress, Second Regular Session, read page by page from the House document server.
Reported May and June 2026
DTI solar panel regulation
A proposal of the Bureau of Philippine Standards, not yet an instrument with a number on this page
Named report
- Status
- A PROPOSAL. Nothing is required of anybody yet
- What it changed
- Would put solar power system products under the mandatory certification the Bureau already runs for other goods, which is the PS mark for what is made here and Import Commodity Clearance for what is brought in. Reported as covering the panels, inverters, charge controllers, batteries and cables sold here. The Department has said publicly that it would not cover the installation, which is the part a household actually buys from an installer, and the installation rules stay where they already are: the Electrical Code, the permits, and the utility.
- How this row was sourced
- The Inquirer, "DTI moves to regulate solar panel systems", 25 May 2026, and "DTI defends solar panel certification", 4 June 2026; GMA News, "DTI eyes mandatory certification for solar power products", 3 June 2026. The Bureau of Philippine Standards publishes its Philippine National Standards for solar photovoltaic energy systems and describes both certification schemes on its own site, and its pages did not answer at all on 26 September 2026; the Department of Trade and Industry tag page for the Bureau carried nothing about solar on the same day. So this row rests on named reports rather than on an advisory from the Department, and it is marked accordingly.
What it adds up to for a household today
If your system sends nothing back to the grid, the August circular governs you and the paperwork is lighter than anything written before it describes. If you want the surplus to earn credit, you are in net metering, the forms belong to whichever utility bills you, and the ten day clock applies while the emergency lasts.
And whatever anyone tells you, there is no household rebate or tax credit to claim. The relief in the Renewable Energy Act is addressed to developers building plant.
What people ask about the rules
What law covers solar panels in the Philippines?
Republic Act 9513, the Renewable Energy Act of 2008, is the statute. Everything since is the Energy Regulatory Commission and the Department of Energy filling in how it works, and there have been three changes in 2026 alone.
The one that changed the most for an ordinary household is Department Circular DC2026-08-0017, issued in August 2026, which took the building permit and the certificate of compliance off micro-solar entirely.
Is the ten working day net metering rule permanent?
No, and almost nothing written about it says so. It comes from Joint Memorandum Circular 001 series of 2026 and it holds for the duration of the State of National Energy Emergency declared under Executive Order 110, unless the Department of Energy revokes it sooner.
Before that circular the period was twenty working days. If the emergency ends without the circular being made permanent, that is the period it goes back to.
Why are two rows on this page blank?
Because the documents could not be opened. The Energy Regulatory Commission’s site refuses an automated request and holds the challenge open rather than clearing it, and the copies mirrored elsewhere are scans with no text in them.
A register whose blank rows are quietly filled from somebody else’s summary is worth less than one that admits the gap. Those two rows say what is missing and why, and nothing on this page is claimed from either.
Does the Renewable Energy Act give me a tax break on my own roof?
Not the one people expect. Section 15(g) zero-rates the sale of power from renewable sources, and gives RE Developers zero-rated VAT on what they buy to build their plant facilities. A household is neither.
The Department of Energy was asked this directly under Freedom of Information in 2022, quoted that section back, and referred the asker to the Bureau of Internal Revenue. There is a fuller account of it on the incentives page.
How current is this?
Every row carries the date of the instrument and how it was sourced, and the page states which rows rest on a news report rather than on the document. It was last checked on 24 September 2026.
If you are budgeting around any of it, check the current position with your own local government and your own distribution utility, because a register is a map and neither of them reads it.
You do not have to read any of this to get a straight answer
Tell us the town, whether you want the surplus to earn credit, and who bills you for electricity. We have been through these with several utilities and we will tell you what yours will ask for.
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.
Sourcing is stated on every row above rather than gathered here, because a single source note at the foot of a register hides which row rests on what. Last checked 24 September 2026. Two rows are open gaps behind the Energy Regulatory Commission's bot protection and nothing on this page is claimed from either. This is a plain reading of public documents and it is not legal advice. Send us the details or use the Message us button and we will talk about your own property.
