The DOE April 2026 circular ended years of unpredictable application timelines. Before this circular, a Filipino solar installer submitting a net metering application had no legal basis to demand a response from their distribution utility within any particular timeframe. Meralco applications routinely sat for 30–60 days. Smaller electric cooperatives sometimes took 90 days or longer. No penalty existed for delay, and customers bore the carrying cost of commissioned systems that could not legally export.
That changed with the April 2026 DOE circular. Three specific mandates now bind every distribution utility and local government unit in the Philippines — a 10-day approval window, a 3-day inspection certificate window, and a 1 MW capacity cap for commercial net metering. This guide explains exactly what the circular requires, how it applies in practice, and what installers and developers need to do differently.
For context on the full Philippine compliance framework, see the Philippines Solar Compliance Guide.
Incomplete Applications Do Not Start the Clock
The 10-day DU approval window only begins when the DU formally deems the application complete. If documents are missing, the DU has 3 working days to notify you of what is missing — but the 10-day clock does not start until you resubmit a corrected, complete package. Submit everything in a single package with a cover letter that explicitly lists every enclosed document by name.
The Three Changes in the April 2026 Circular
The April 2026 DOE circular amended the Philippine net metering framework at three specific points. Each change addresses a distinct bottleneck that has limited solar deployment.
Change 1: Mandatory 10-Working-Day DU Approval Window
| Before April 2026 | After April 2026 | |
|---|---|---|
| DU approval timeline | No legal requirement | 10 working days from complete application |
| DU response to incomplete application | No requirement | Must notify within 3 working days, specify what is missing |
| Penalty for non-compliance | None | ERC complaint mechanism; ERC may impose penalties |
| Practical timeline (Meralco) | 30–60 days typical | 10 working days (legally enforceable) |
| Practical timeline (rural EC) | 60–90 days typical | 10 working days (legally enforceable) |
This is the most operationally significant change. For the first time, installers can give customers a definitive commitment: “Once your application is submitted and deemed complete, your DU has 10 working days to respond.” That is a firm basis for project scheduling that did not previously exist.
Change 2: Mandatory 3-Working-Day LGU CFEI Processing
| Before April 2026 | After April 2026 | |
|---|---|---|
| CFEI issuance timeline | No legal requirement | 3 working days from inspection |
| Electrical permit processing | Varied by LGU; no national standard | Covered under the 3-day processing requirement |
| LGU non-compliance | No mechanism | DOE follow-up; repeat non-compliance referred to DILG |
| Practical impact | Booking inspection + waiting for CFEI could take 2–4 weeks | Post-inspection wait is capped at 3 working days |
Note carefully: the 3-day requirement covers processing time after the inspection appointment occurs — not the time to schedule the inspection itself. In LGUs with heavy workloads, scheduling delays at the booking stage remain possible. Book the inspection on commissioning day, not after all other documents are ready.
Change 3: Net Metering Capacity Cap Lifted to 1 MW
| Before April 2026 | After April 2026 | |
|---|---|---|
| Residential capacity limit | No practical cap (size to load) | No practical cap (size to load) |
| Commercial / industrial cap | 100 kW | 1 MW |
| Systems above 1 MW | Must use RE developer framework | Must use RE developer framework |
| Impact on commercial projects | Projects 100–1,000 kW had no net metering pathway | Projects up to 1 MW can access net metering |
The 100 kW cap was a major structural barrier. A medium-sized factory or commercial building with 1,000–3,000 sqm of usable roof area could install 300–500 kW of solar, but could only register 100 kW under net metering. The rest had no straightforward monetization mechanism under the previous rules. The 1 MW cap lift directly addresses this.
The 10-Day DU Approval Rule
What Counts as a Complete Application
The 10-day clock begins only when the DU formally determines that the application is complete. A complete application contains all of the following:
| Document | Notes |
|---|---|
| DU Net Metering Application Form | Fully completed, signed by the consumer |
| Certificate of Compliance (CoC) | Signed and sealed by a licensed RME or PEE |
| As-Built Electrical Single-Line Diagram | Must show PV array, inverter, AC wiring, protection devices, metering point |
| Bill of Materials | Includes panel brand/model, inverter brand/model, cable specs, protection device specs |
| Certificate of Final Electrical Inspection (CFEI) | Issued by the LGU engineering office after physical inspection |
| Proof of Ownership or Lease | Transfer Certificate of Title (TCT), or lease agreement with owner consent |
| Latest Electricity Bill | Shows account number, service address, and consumption history |
Some DUs have additional requirements — for example, Meralco may request load data or a site layout drawing for larger systems. Confirm the DU’s current checklist before preparing documents.
What DUs Can and Cannot Do
Under the circular, a DU may reject an application if:
- The proposed system exceeds the customer’s contracted demand or service entrance capacity
- The system does not include anti-islanding protection compliant with Philippine standards
- The CoC is not signed by a currently licensed RME or PEE (verifiable via PRC records)
- The CFEI is missing or issued by an entity without jurisdiction
- The system’s proposed export capacity exceeds safe operating limits for the local distribution network segment
A DU cannot:
- Reject an application solely because of internal workload or processing backlog
- Impose additional document requirements not published in their official net metering procedures
- Delay approval beyond 10 working days on a complete application without formal written notification citing specific regulatory grounds
- Require that the bidirectional meter be supplied by the consumer (the DU supplies and installs the net meter)
Escalation if the DU Does Not Comply
If 10 working days pass from confirmed complete submission with no response:
- Follow up in writing to the DU’s net metering supervisor, citing the DOE April 2026 circular and your submission date
- If no response within 2 additional working days, file a complaint with the ERC at erc.gov.ph
- Include: copy of submission receipt (with date), cover letter listing submitted documents, and the DOE circular reference
- The ERC has authority to require the DU to process the application and may impose penalties for documented violations
Keep all submission records — digital and physical. The date-stamped receipt from your initial submission is the key document in any escalation.
The 3-Day LGU Permit Rule
Which Permits Are Covered
The DOE circular covers LGU-issued documents that are part of the solar installation permit and inspection process:
- Certificate of Final Electrical Inspection (CFEI): The primary document. Issued after the LGU’s engineering office physically inspects the commissioned installation.
- Electrical Permit: The permit issued before installation begins, authorizing the electrical work. Processing of this permit is also subject to expedited handling under the 3-day rule where the LGU has received a complete application for the permit.
The 3-day window applies to processing time after the application or inspection has been received — it does not obligate the LGU to schedule an inspection within 3 days of a request.
How to Book the LGU Inspection
Bring to the LGU appointment:
- Completed electrical permit application (if not already obtained before installation)
- As-built electrical plans (single-line diagram, layout drawings)
- Certificate of Compliance (CoC) from the installation engineer
- Bill of materials
- Building permit or occupancy certificate (for the structure)
- Valid government-issued ID of the property owner or authorized representative
Some LGUs require a formal letter of request for the CFEI inspection. Call the city or municipal engineering office before your visit to confirm their current requirements.
If Your LGU Does Not Comply
If the LGU fails to issue the CFEI within 3 working days of the inspection:
- Follow up in writing with the city or municipal engineer’s office, citing the DOE April 2026 circular
- If the delay continues, escalate to the DOE regional office with documentation of the inspection date and the delay
- Repeat violations by an LGU can result in DOE referral to the Department of Interior and Local Government (DILG) for administrative action
LGU Scheduling vs LGU Processing Are Different
The 3-day rule covers processing time after inspection — not scheduling time before it. If an LGU has a 2-week backlog in booking inspections, the circular does not eliminate that wait. Book the LGU inspection on the day the system is commissioned. Do not wait. The 3-day post-inspection processing window means that once the inspector visits, you get the CFEI quickly — but you still need to get the inspector there first.
The 1 MW Cap Lift
Who Benefits
The 1 MW cap lift directly opens net metering access to a large segment of the Philippine commercial and industrial market:
| Consumer Type | Before April 2026 | After April 2026 |
|---|---|---|
| Residential | No practical cap (size to load) | No change |
| Small commercial (retail, offices under 100 kW load) | Net metering available | No change |
| Medium commercial (malls, warehouses, 100–500 kW) | Only 100 kW registrable under net metering | Up to 1 MW registrable |
| Light industrial (factories, 200–800 kW) | Only 100 kW registrable | Up to 1 MW registrable |
| Large industrial (above 1 MW load) | 100 kW cap; rest of system unmonetized | Up to 1 MW registrable; above 1 MW uses RE developer framework |
What It Means for Commercial Installers
For commercial solar installers, the 1 MW cap lift creates genuine new pipeline. Projects that were previously financially marginal — because only 100 kW of a 400 kW system could earn export credits — are now fully viable under net metering for the entire capacity.
A 500 kW commercial rooftop system in Metro Manila generates approximately 750–800 MWh/year (at 4.8 peak sun hours/day). At Meralco’s BGC rate of approximately PHP 5.50/kWh, that is roughly PHP 4.1–4.4 million/year in energy value (combination of avoided consumption and export credits). The difference between crediting 100 kW and crediting 500 kW under net metering is material to project economics.
Use SurgePV’s generation and financial tool to model the full financial impact of the 1 MW cap lift on specific commercial projects — including the difference in payback period and IRR between the pre- and post-April 2026 regime for systems between 100 kW and 1 MW.
Systems Above 1 MW
Systems above 1 MW do not qualify for net metering and fall under the RE developer framework governed by the DOE and the RE Act (RA 9513). Developers of systems above 1 MW must obtain:
- Renewable Energy Service/Operating Contract (RESOC) from the DOE
- Compliance with DOE’s RE permitting process
- Separate interconnection agreement with the DU under TRANSCO/ERC grid access rules
For most commercial installers, the 1 MW cap covers the vast majority of rooftop projects. The RE developer framework is relevant for ground-mount, carport, and large industrial roof projects that genuinely exceed 1 MW of capacity.
Step-by-Step: Navigating the New Timeline
Prepare a Complete Application Package Before Submitting
The 10-day clock only starts when the DU deems the application complete. Prepare all documents in advance: completed DU application form, Certificate of Compliance (CoC) from a licensed electrical engineer, as-built single-line diagram, bill of materials, Certificate of Final Electrical Inspection (CFEI) from the LGU, proof of ownership, and latest electricity bill. Submit as a single package with a cover letter explicitly itemizing each document by name and page count. Do not submit partially and plan to send remaining documents later — this resets the clock.
Get the CFEI Before Filing with the DU
Secure the CFEI from your city or municipal engineering office first. Under the April 2026 DOE circular, LGUs must issue the CFEI within 3 working days of the inspection appointment. Book the inspection as soon as the system is commissioned — on commissioning day if possible. Bring the completed electrical permit application, as-built plans, CoC, bill of materials, and the property owner’s authorization letter to the LGU appointment. The 3-day post-inspection window means that once the inspector visits, you can expect the CFEI within 3 working days. Do not book the LGU inspection as an afterthought — it is the critical path document for the DU application.
Submit to the DU and Request a Date-Stamped Receipt
Submit the complete package to your DU’s net metering desk or online portal. For Meralco, this is typically through their online application portal with physical document submission at designated offices. For smaller DUs, in-person submission to the engineering department may be required. Request an official receipt with the submission date stamped or digitally confirmed. This document is your proof of the submission date and the legal start point for the 10-day clock. Keep a digital copy of every submitted document — photograph physical documents before submission.
Track the 10-Day Window and Escalate If Needed
Count 10 working days from the date your application was formally acknowledged as complete. If you receive no response by day 9, contact the DU’s net metering hotline or responsible officer to follow up in writing. If no action is taken by day 10, you have grounds to file a complaint with the ERC. File via the ERC’s official complaint mechanism at erc.gov.ph. Include: date-stamped submission receipt, your cover letter listing submitted documents, and the DOE circular reference. Document every follow-up communication with timestamps.
Proceed to Meter Installation After Approval
Once the DU issues written approval, schedule the bidirectional meter installation. The DU supplies and installs the net meter at their cost in most cases — confirm this with your DU. Most DUs complete meter replacement within 5–10 working days of written approval. A DU technician visits the site to remove the existing meter and install the bidirectional unit. Net metering billing takes effect from the first full billing cycle after the new meter is installed. On the first net-metered bill, confirm that the export credit rate shown matches the blended generation rate (BGC) on the bill’s generation charge section.

Common Application Problems
The most common reasons Philippine net metering applications are delayed or rejected — and what to do about each:
| Problem | What Happens | How to Prevent |
|---|---|---|
| Missing or unsigned CoC | DU rejects application within 3 days; clock resets on resubmission | Verify the RME/PEE has signed and applied their dry seal before including the CoC in the package |
| CFEI missing | Application deemed incomplete; 10-day clock does not start | Secure CFEI before starting the DU application — it is always the longest-lead document |
| Single-line diagram does not show metering point | DU requests revision; clock pauses | Have the installation engineer draw the diagram to include the existing meter location and the bidirectional meter location |
| System capacity exceeds service entrance | DU rejects application; service entrance upgrade required before resubmission | Check the contracted demand and service entrance size before finalizing system design |
| CoC signed by engineer without current PRC license | DU rejects CoC; application incomplete | Verify the signing engineer’s PRC license number and expiry date before accepting the CoC |
| Proof of ownership not in the account holder’s name | DU cannot verify applicant relationship to property | Obtain an authorization letter from the registered owner if the applicant is a tenant or lessee; attach the lease agreement |
| Incomplete bill of materials (missing inverter model) | DU cannot verify anti-islanding compliance | Include full brand, model number, and rated output for all major components |
| Application submitted to wrong DU office | No processing begins until received at correct location | Confirm the correct receiving office with the DU before visiting; get the address and officer name |
Pro Tip: Call the DU Before You Submit
Even with a standard document checklist, individual DUs sometimes have current supplementary requirements that are not yet reflected on their website. Before submitting any net metering application, call the DU’s engineering department and ask: “Is your current net metering document checklist the same as what’s posted on your website?” A two-minute phone call can prevent a rejected application that resets your 10-day clock.
Frequently Asked Questions
What did the DOE April 2026 circular change for net metering in the Philippines?
The DOE April 2026 circular introduced three significant changes: distribution utilities must approve or reject complete net metering applications within 10 working days; LGUs must issue the Certificate of Final Electrical Inspection (CFEI) and related electrical permits within 3 working days; the net metering capacity cap for non-residential consumers was lifted from 100 kW to 1 MW. These changes are binding on all distribution utilities and LGUs nationwide.
What happens if a DU does not approve my application within 10 working days?
If a distribution utility fails to act on a complete application within 10 working days, the applicant may escalate to the Energy Regulatory Commission (ERC) and file a complaint. The ERC has authority to impose penalties on DUs that violate the processing timeline. Document your submission with a date-stamped receipt from the DU and keep records of all follow-up communications.
Does the 10-day clock start from the date I submit, or from when my application is deemed complete?
The 10-day clock starts from when the DU deems the application complete — meaning all required documents are present and properly signed. If your application is incomplete, the DU must notify you within 3 working days and specify what is missing. The clock does not start until you resubmit the corrected package. Always submit with a detailed cover letter listing all enclosed documents to help the DU confirm completeness quickly.
Which LGUs are covered by the 3-day electrical permit rule?
The 3-day processing requirement applies to all LGUs (cities and municipalities) nationwide. The rule covers the issuance of the Certificate of Final Electrical Inspection (CFEI) and any LGU-issued electrical permits required as part of the solar installation process. LGUs that fail to comply are subject to DOE follow-up and, in repeated cases, referral to the Department of Interior and Local Government (DILG).
What is the new capacity cap for commercial solar net metering in the Philippines?
The April 2026 DOE circular lifted the non-residential net metering capacity cap from 100 kW to 1 MW. Commercial and industrial consumers can now install and register up to 1 MW of rooftop solar under the net metering program. Residential consumers have no practical cap beyond sizing the system to match actual consumption. Systems above 1 MW fall under the RE developer framework under RA 9513.
