Davao Light and Power Company is the distribution utility (DU) serving Davao City and surrounding areas in Mindanao. As part of the Aboitiz Power group, Davao Light administers net metering under ERC Resolution No. 09-2013 and the DOE’s Renewable Energy Act implementing rules. The April 2026 DOE circular introduced mandatory 10-day DU response windows and 3-day LGU inspection timelines — changes that directly affect how solar installations in Davao City are processed. This guide covers the full Davao Light net metering application workflow for solar installers and homeowners.
Davao Light’s Service Area
Davao Light serves Davao City — the largest city by land area in the Philippines — and extends into parts of Davao del Norte including municipalities near Panabo and Tagum. The key point for solar installers: not every address in greater Davao is served by Davao Light. Portions of the surrounding provinces are served by electric cooperatives (cooperatives are regulated separately and have their own net metering processes).
Before designing a system or beginning the permit process, confirm the customer is a Davao Light account holder. The simplest way is to look at the electric bill — the distribution utility is printed at the top. If the bill shows Davao Light (or DLPC), the net metering application goes through Davao Light. If it shows a cooperative name (e.g., DASURECO, Davao del Sur Electric Cooperative), the cooperative net metering process applies instead.
Davao Light’s service area covers most of Davao City’s urban and suburban barangays, including Poblacion, Buhangin, Agdao, Talomo, Calinan, Toril, Tugbok, Baguio, and others. For barangays on the outer edges of the city or in adjacent municipalities, verification is essential.
The April 2026 DOE Circular: What Changed for Davao
The April 2026 Department of Energy circular introduced binding timelines that apply to all distribution utilities, including Davao Light. The two most significant changes:
10-day DU response: Davao Light must review and respond to a complete net metering application within 10 working days. A “response” means either formal approval with a meter installation schedule, a written request for specific missing documents, or a written denial with stated grounds. Silence does not constitute denial or approval.
3-day CFEI issuance: The Davao City Engineering Office must issue the Certificate of Final Electrical Inspection within 3 working days of a scheduled inspection — down from the previous practice that could take 2–3 weeks. This change significantly compresses the pre-application timeline.
The circular also clarified that the 1 MW per system cap under the previous rules has been lifted for commercial and industrial customers. Residential customers remain subject to the contracted demand cap (system output cannot exceed 100% of the contracted demand level).
Required Documents Checklist
A complete Davao Light net metering application requires the following:
| Document | Source | Notes |
|---|---|---|
| Davao Light net metering application form | DLPC customer service office or website | Must be fully completed and signed |
| Certificate of Compliance (CoC) | Licensed RME or PEE (signing engineer) | Must reference the specific installation address |
| As-built single-line diagram | Signing engineer | Shows inverter, string configuration, protection devices, grid connection point |
| Bill of materials | Installer | Lists panels, inverter, mounting, wiring, protection |
| CFEI from Davao City Engineering Office | Davao City CEO after site inspection | Requires prior electrical permit |
| Electrical permit (original) | Davao City CEO (obtained before installation) | Must be for the solar installation |
| Proof of ownership or lease | Customer | Title, tax declaration, or lease agreement |
| Government-issued ID | Customer | Any primary ID |
| Latest Davao Light bill | Customer | Confirms account number and contracted demand |
| ERC-prescribed net metering agreement | Signed by customer | DLPC provides the form |
Document Completeness Is the Critical Variable
Under the 10-day rule, Davao Light’s clock starts when a complete application is received. Incomplete applications — missing the CFEI, unsigned CoC, or absent bill of materials — restart the clock when the missing item is finally submitted. Verify the full checklist before submission to avoid unnecessary delays.
Step-by-Step Application Process
Engage a Davao-based installer with a licensed engineer
Choose a solar installer operating in Davao City with a PRC-licensed Registered Master Electrician (RME) or Professional Electrical Engineer (PEE) on staff. The engineer signs the Certificate of Compliance after installation — this is a legal document, not a formality. Ask for the engineer’s PRC license number before engaging and verify at prc.gov.ph. Davao City has experienced solar contractors familiar with both the Davao City CEO permit process and Davao Light’s application requirements. Selecting an installer who has completed prior Davao Light net metering applications saves significant time.
Obtain the electrical permit from Davao City CEO before construction
Apply at the Davao City Engineering Office for the electrical permit before installation begins. Required documents: electrical plan (single-line diagram and layout), bill of materials, PRC license of the signing engineer, proof of ownership or occupancy. Fees for residential systems run approximately PHP 500–2,500 depending on system size. The permit must be obtained and posted at the site before any installation work begins. Allow 3–7 working days for issuance under normal conditions.
Complete installation following Philippine Electrical Code requirements
Installation must comply with the Philippine Electrical Code (PEC) — the national standard governing solar PV installations alongside the DOE and ERC technical guidelines. Critical compliance points: correct DC and AC protection device ratings, earthing/grounding per PEC requirements, anti-islanding function of the grid-tie inverter, and secure mounting that meets Davao City’s structural requirements. Davao City is within a typhoon-affected region — mounting must meet appropriate wind load standards. Have the signing engineer present during or immediately after installation to verify compliance before signing the CoC.
Schedule and complete the CFEI inspection with Davao City CEO
After installation, schedule the final electrical inspection at the Davao City Engineering Office. Bring: the as-built electrical plans (stamped with any changes from the permit plans), the original electrical permit, and the signed CoC. Under the April 2026 DOE mandate, the CEO must issue the CFEI within 3 working days of the inspection. The CFEI confirms that the installed system matches the permitted plans and complies with the PEC. It is a non-negotiable requirement for the Davao Light application.
Submit to Davao Light and monitor the 10-day window
Submit the complete document package to Davao Light’s customer service office. Request a date-stamped receipt — this establishes the start of the 10-working-day window. If Davao Light requests additional documents, respond promptly, as the clock may reset. If no response is received by day 9, follow up in writing. If no action is taken by the end of day 10, this constitutes a violation of the DOE mandate and should be escalated to the ERC consumer affairs division.
Accept meter installation and verify the first net metered bill
Upon approval, Davao Light schedules bidirectional meter installation, typically within 5–10 working days. The existing meter is replaced with a two-way meter that records both consumption from the grid and export to the grid separately. Once the meter is installed, net metering billing begins on the next billing cycle. Check the first bill carefully: the BGC credit should appear as a separate line item, expressed in PHP per kWh exported. The credit carries forward monthly — it does not expire within the calendar year.
Davao City Solar ROI: Does It Still Make Sense?
The most common question from Davao City solar customers is whether lower electricity rates (compared to Meralco) make solar less worthwhile. The answer is no — but the math differs from Manila.
Key inputs for Davao:
- Davao Light retail rate: approximately PHP 9.50–10.50/kWh (all-in blended rate including generation, transmission, distribution, system loss, and taxes)
- Average peak sun hours in Davao City: approximately 4.5 hours/day
- BGC export rate: approximately PHP 4.50–5.50/kWh (blended generation component only)
Worked example: 5 kWp residential system
- Annual yield: 5 kWp × 4.5 peak sun hours × 365 days × 0.80 (system efficiency) ≈ 6,570 kWh/year
- Self-consumed at home (70% assumption): 4,599 kWh × PHP 10/kWh = PHP 45,990 savings
- Exported to grid (30%): 1,971 kWh × PHP 5/kWh = PHP 9,855 credit
- Total annual benefit: approximately PHP 55,845
At a system cost of PHP 250,000–280,000 for a quality 5 kWp installation, simple payback runs approximately 4.5–5 years — well within the 25-year panel warranty period.
| System Size | Annual Yield | Annual Savings (70% self-use) | System Cost (est.) | Simple Payback |
|---|---|---|---|---|
| 3 kWp | ~3,942 kWh | ~PHP 33,500 | PHP 150,000–175,000 | 4.5–5.2 years |
| 5 kWp | ~6,570 kWh | ~PHP 55,845 | PHP 250,000–280,000 | 4.5–5.0 years |
| 8 kWp | ~10,512 kWh | ~PHP 89,350 | PHP 380,000–440,000 | 4.3–4.9 years |
| 10 kWp | ~13,140 kWh | ~PHP 111,690 | PHP 470,000–550,000 | 4.2–4.9 years |
Annual yield based on 4.5 peak sun hours, 0.80 system performance ratio. Savings use PHP 10/kWh retail and PHP 5/kWh BGC export.
Pro Tip: Self-Consumption Drives Payback More Than System Size
In Davao, the difference between 50% and 80% self-consumption on a 5 kWp system is approximately PHP 15,000 in annual savings — nearly a full year of payback period. Sizing the system to match daytime consumption (not to maximize generation) consistently produces faster payback. Use solar financial modeling software to run self-consumption sensitivity scenarios before quoting system size to the customer.
Davao Light vs Meralco vs VECO: Net Metering Comparison
| Parameter | Davao Light (DLPC) | Meralco | VECO (Cebu) |
|---|---|---|---|
| Coverage | Davao City + parts of Davao del Norte | Metro Manila, Rizal, Bulacan, Cavite, Laguna, Pampanga | Cebu City and 56 municipalities in Cebu province |
| Retail rate (all-in, approx.) | PHP 9.50–10.50/kWh | PHP 10.50–11.50/kWh | PHP 10.00–11.00/kWh |
| BGC export rate (approx.) | PHP 4.50–5.50/kWh | PHP 5.00–6.00/kWh | PHP 4.80–5.80/kWh |
| Peak sun hours | ~4.5 hours/day | ~4.8 hours/day | ~5.2 hours/day |
| Application method | In-person at DLPC customer office | Online portal (meralco.com.ph) or in-person | In-person at VECO customer center |
| DU response deadline | 10 working days (DOE 2026) | 10 working days (DOE 2026) | 10 working days (DOE 2026) |
| LGU inspection deadline | 3 working days (DOE 2026) | 3 working days (DOE 2026) | 3 working days (DOE 2026) |
The BGC rate varies monthly for all three DUs because it tracks the blended generation cost — which changes with fuel prices and the generation mix. Meralco customers generally see higher BGC rates due to a different generation mix; Davao Light and VECO are broadly similar.
Slightly Lower Rates, Slightly Lower Yield — Similar Payback
Davao City’s lower electricity rates and slightly lower irradiance (4.5 vs 4.8–5.2 peak sun hours in Manila/Cebu) roughly cancel each other out in terms of payback period. Davao solar installations typically achieve payback within 0.5–1 year of comparable Manila or Cebu systems, not the 2–3 year difference customers sometimes assume.
Practical Tips for Davao Solar Installers
Verify account type before designing. Electric cooperatives in Davao del Norte and surrounding provinces operate under different net metering processes. Confirming the customer is a DLPC account holder takes 30 seconds — missing this can waste days of permitting effort.
Coordinate CFEI scheduling early. The Davao City CEO inspection calendar can fill up. Schedule the post-installation inspection as soon as you have a reliable completion date — do not wait until the day of completion to call for an appointment. Under the 3-day mandate, the CEO must issue the CFEI within 3 working days of the inspection, not 3 working days from when you call to schedule.
Use the net metering agreement form from DLPC. Davao Light provides its own ERC-prescribed net metering agreement form. Some installers use a generic form downloaded online — Davao Light may reject this and require resubmission with the DLPC version. Get the current form from the customer service office.
Document the BGC rate in the proposal. Customers often focus on the self-consumption savings and overlook that the BGC export credit is significantly lower than the retail rate. Setting this expectation correctly — and designing for high self-consumption — avoids post-installation disappointment when the first bill shows a smaller credit than expected.
Use solar design software that supports Philippine BGC modeling. Generating an accurate financial proposal for a Davao Light customer requires entering the correct retail rate, BGC export rate, peak sun hours for Davao City, and self-consumption profile. Installers using generic spreadsheets frequently miscalculate because they apply the retail rate to exported energy. Solar software built with Philippine utility data handles this correctly.

Understanding the BGC Export Credit
The blended generation rate (BGC) is the price at which your exported solar energy is credited to your bill. It is not the same as your retail electricity rate. The difference matters because:
- Your retail rate (PHP 9.50–10.50/kWh) includes generation, transmission, distribution, system loss charges, and various taxes and levies
- The BGC covers only the generation component — approximately PHP 4.50–5.50/kWh for Davao Light
- The remaining charges (transmission, distribution, etc.) are not credited for exported energy — only for energy consumed on-site
This means that each kWh consumed directly from your solar panels saves you the full retail rate (PHP 10/kWh), while each kWh exported to the grid earns you only the BGC (PHP 5/kWh). The financial implication: every Philippine solar system should be sized and designed to maximize self-consumption, not to maximize total generation.
For system sizing and financial modeling against Davao Light’s rates, the Philippines solar ROI calculator provides a scenario-based tool for comparing payback across different self-consumption rates.
Escalation: What to Do If Davao Light Misses the 10-Day Deadline
Under the DOE April 2026 mandate, failure to respond within 10 working days is a regulatory violation. If this occurs:
- Send a written follow-up to Davao Light’s customer service office, referencing the date-stamped receipt and the 10-working-day requirement
- Escalate to the ERC consumer affairs division — file a formal complaint at the ERC office or through the ERC’s online complaint portal
- Copy the DOE’s Renewable Energy Management Bureau (REMB) on the complaint — the REMB monitors DU compliance with the April 2026 circular
In practice, most Davao Light applications are processed within the window for complete submissions. Incomplete applications — missing documents that require back-and-forth — are the most common source of perceived delays.
Frequently Asked Questions
What areas does Davao Light cover for net metering?
Davao Light and Power Company covers Davao City and neighboring areas including portions of Davao del Norte. Within Davao City, Davao Light serves most urban and suburban barangays. For areas outside Davao City proper, check with the relevant electric cooperative. Confirm by checking the customer’s electric bill.
What is Davao Light’s net metering export rate?
Davao Light credits exported electricity at the blended generation rate (BGC), consistent with ERC Resolution No. 09-2013. Davao Light’s BGC is approximately PHP 4.50 to PHP 5.50 per kWh, varying monthly with generation charges. Self-consumption saves more per kWh than exporting.
How do I apply for net metering with Davao Light?
Submit the complete application package to Davao Light’s customer service office. Required documents: Davao Light application form, Certificate of Compliance, as-built single-line diagram, bill of materials, CFEI from Davao City CEO, proof of ownership, and your latest DLPC bill. Davao Light must respond within 10 working days.
Does Davao City solar make financial sense given lower electricity rates?
Yes. A 5 kWp system in Davao typically generates annual savings of PHP 50,000–60,000 at 70% self-consumption, producing payback in approximately 4.5–5 years from a PHP 250,000–280,000 investment.
What is the CFEI process for Davao City?
The CFEI is issued by the Davao City Engineering Office after a post-installation inspection. Schedule the inspection as soon as installation is complete. Under the DOE April 2026 mandate, the CEO must issue the CFEI within 3 working days of the inspection date.
