What Is Republic Act 9513?

Republic Act 9513, officially titled the Renewable Energy Act of 2008, is the primary Philippine law governing the development, promotion, and utilization of renewable energy resources. It was signed into law on December 16, 2008 by President Gloria Macapagal-Arroyo and has been implemented progressively by the Department of Energy (DOE) and the Energy Regulatory Commission (ERC).

For Filipino homeowners and businesses, RA 9513 matters primarily because it creates three enforceable rights: the right to connect a solar system to the grid and receive net metering credits, the right to purchase solar equipment VAT-free, and the right to access a government-supported framework for renewable energy installation. These rights apply to any property within the Meralco franchise area and any other distribution utility in the Philippines.

Key Solar Incentives Under Republic Act 9513

RA 9513 provides five categories of incentives relevant to residential and commercial solar panel installation in the Philippines. SolarPro Install applies all applicable incentives to every project.

1. Net Metering Program

Section 10 of RA 9513 mandates that distribution utilities like Meralco must implement a net metering program for renewable energy systems up to 100 kW. Under net metering, any excess solar electricity your system exports to the Meralco grid earns bill credits on your next monthly statement. This is the most financially significant incentive for homeowners and the legal foundation of the entire ERC Net Metering Program.

2. VAT Exemption on Solar Equipment

RA 9513 exempts the sale of renewable energy equipment — including solar panels, inverters, mounting systems, and installation components — from Value Added Tax. At the current 12% VAT rate, this exemption directly reduces your upfront installation cost. On a ₱480,000 solar installation, the VAT exemption represents approximately ₱57,600 in savings. SolarPro Install applies this exemption on all equipment in every project.

3. Renewable Energy Portfolio Standard (RPS)

RA 9513 requires electricity suppliers to source a minimum percentage of their electricity from renewable energy. This RPS obligation creates a national demand for renewable energy generation, supporting the policy environment that makes solar installation financially viable in the Philippines. It also provides the basis for Renewable Energy Certificates (RECs) which your solar system may generate.

4. Feed-in Tariff (FIT) System

RA 9513 created the Feed-in Tariff system, which guarantees priority dispatch and fixed payment rates for electricity generated by renewable energy developers. While the FIT primarily applies to large-scale RE developers and not to typical residential or commercial solar installations, it supports the overall renewable energy ecosystem and indirectly affects the availability and pricing of solar equipment in the Philippines.

5. DOE Accreditation Framework

RA 9513 created the Department of Energy accreditation framework for renewable energy installers. DOE accreditation confirms that a solar installer meets Philippine government standards for equipment quality, installation methods, and professional qualifications. SolarPro Install is DOE-accredited, confirming that our team, processes, and equipment meet RA 9513 standards.

6. Income Tax Holiday for RE Developers

RA 9513 provides an income tax holiday for registered renewable energy developers for the first seven years of commercial operations. While this primarily applies to large-scale RE project developers rather than individual homeowners, it incentivizes investment in the renewable energy sector that supports panel manufacturing, supply chain development, and competitive pricing in the Philippine solar market.

The VAT Exemption in Peso Terms: What It Means for Your Installation

The VAT exemption under RA 9513 reduces your upfront solar installation cost by approximately 12 percent on the equipment component. Here is the actual peso impact by system size.

System Size	Installation Cost	VAT Saved (12%)	Cost Without Exemption
3 kWp	₱200K–₱280K	₱24K–₱33.6K	₱224K–₱314K
5 kWp	₱350K–₱480K	₱42K–₱57.6K	₱392K–₱538K
8 kWp	₱560K–₱680K	₱67.2K–₱81.6K	₱627K–₱762K
10 kWp	₱700K–₱900K	₱84K–₱108K	₱784K–₱1.008M

The green column shows the actual savings delivered by the RA 9513 VAT exemption. SolarPro Install applies this exemption to all eligible equipment on every project automatically.

RA 9513 Makes Solar a Legal Right. Not Just a Good Idea.

How RA 9513 Is Implemented: DOE, ERC, and Meralco

RA 9513 is a framework law. Implementation is carried out by three government bodies, each with a specific role in making solar installation viable for Filipino customers.

DOE

Department of Energy

The DOE is the primary implementing agency for RA 9513. It sets policy, issues implementing rules and regulations, maintains the registry of renewable energy developers and installers, and monitors compliance. DOE accreditation of solar installers confirms compliance with RA 9513 installation standards. SolarPro Install is DOE-accredited.

ERC

Energy Regulatory Commission

The ERC administers the Net Metering Program mandated by Section 10 of RA 9513. It sets the rules for how distribution utilities like Meralco must implement net metering, including system size limits, application processes, billing mechanisms, and installer accreditation. The ERC Advisory dated September 22, 2025 is the latest regulatory update to the net metering rules. SolarPro Install is ERC Net Metering accredited.

MRL

Meralco as Distribution Utility

Meralco is the distribution utility responsible for implementing net metering within its franchise area covering Metro Manila, Cavite, Laguna, and Bulacan. RA 9513 requires Meralco to accept net metering applications, conduct the Distribution Impact Study, install bi-directional meters, and credit exported electricity on monthly bills. Meralco cannot refuse a qualified net metering application from a compliant solar installation.

BIR

Bureau of Internal Revenue

The BIR implements the VAT exemption provisions of RA 9513. Solar installers must apply the VAT exemption on qualifying renewable energy equipment at the point of sale. SolarPro Install applies the VAT exemption on all eligible equipment components in every project as a standard practice.

The Net Metering Provision: Section 10 of RA 9513

Section 10 of Republic Act 9513 specifically mandates the Net Metering Program. The law requires that the ERC establish the rules for net metering and that all distribution utilities comply. Key provisions of Section 10 that directly affect Meralco customers include the following.

Mandatory Acceptance

Distribution utilities are required to accept net metering applications from qualified end-users with compliant renewable energy systems up to 100 kW. Meralco cannot arbitrarily refuse a properly submitted application from a system installed by an accredited installer.

Bill Credit Mechanism

Exported electricity must be credited to the customer’s next monthly bill. The credit is calculated at the applicable distribution rate. Under proposed ERC amendments (DC2024-08-0025), credits shall be rolled over to succeeding billing periods on a mandatory basis.

100 kW Capacity Limit

The maximum system size eligible for net metering under RA 9513 is 100 kilowatts of AC output. Residential systems of 3 kWp to 10 kWp are well within this limit. Commercial systems up to 100 kW also qualify.

ERC Rules Govern Process

The Energy Regulatory Commission sets the specific rules, processes, and requirements for net metering implementation. The current rules reflect the ERC Advisory dated September 22, 2025 and the proposed amendments in DC2024-08-0025.

Proposed Amendments to RA 9513 Net Metering Rules

The ERC has proposed formal amendments to the Net Metering Rules under DC2024-08-0025. These proposed changes strengthen the rights of solar customers under RA 9513 and clarify implementation details.

NEW

Credits Become Mandatory Carry-Over

The current rule states credits “may” be banked and rolled over. The proposed amendment changes this to “shall” — making credit carry-over a mandatory entitlement rather than a discretionary benefit. Unused credits from one month must be applied to the following month’s bill.

NEW

Credits Transfer to New Property Owner

When a property with a solar system is sold, accumulated net metering credits transfer to the new owner, subject to documentation requirements and execution of a new Net Metering Agreement with Meralco. This means solar credits have property value implications.

NEW

REC Meter Is Voluntary

The Renewable Energy Certificate meter installation is no longer mandatory. Customers who choose not to install a REC meter must sign a notarized affidavit of waiver. RECs can still be calculated using the official ERC formula: REC per Month = Installed Capacity × Capacity Factor (19.2775% for rooftop solar) × DC/AC Ratio (0.809312) × Hours per Month.

NEW

DIMC Fee Capped at ₱3,000 for Residential

The ERC Advisory dated September 22, 2025 confirmed that the Difference in Meter Cost (DIMC) fee for residential net metering customers shall not exceed ₱3,000. This protects homeowners from inflated meter replacement charges.
