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 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 at every stage of the solar panel installation process in the Philippines, from initial system design through Meralco net metering registration.
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. 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.
2. VAT Exemption on Solar Equipment
RA 9513 exempts solar panels, inverters, mounting systems, and installation components from Value Added Tax. At the current 12% VAT rate, this directly reduces your upfront installation cost. On a ₱480,000 system, the VAT exemption represents approximately ₱57,600 in savings. SolarPro Install applies this exemption to all equipment in every project.
3. Renewable Energy Portfolio Standard
RA 9513 requires electricity suppliers to source a minimum percentage of electricity from renewable energy. This creates a national demand for RE generation and supports the policy environment that makes solar installation financially viable. It also provides the basis for Renewable Energy Certificates (RECs) your solar system may generate.
4. Feed-in Tariff System
RA 9513 created the Feed-in Tariff system, which guarantees priority dispatch and fixed payment rates for electricity from renewable energy developers. While FIT primarily applies to large-scale RE developers, it supports the overall RE ecosystem and affects the availability and pricing of solar equipment in the Philippines. For a complete breakdown of how the two programs differ and which applies to Meralco customers, see our guide on
net metering vs feed-in tariff programs under RA 9513.
5. DOE Accreditation Framework
RA 9513 created the Department of Energy accreditation framework for renewable energy installers.
DOE-accredited solar installers in the Philippines are listed in a public government registry that customers can verify before signing a contract — accreditation confirms the installer meets Philippine standards for equipment quality, installation methods, and professional qualifications.
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. This primarily applies to large-scale RE project developers, but it incentivizes investment in the RE sector that supports panel manufacturing 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 installation cost by approximately 12 percent on the equipment component. The table below shows what the exemption saves at each system size compared to what you would pay without it.

RA 9513 Makes Solar a Legal Right. Not Just a Good Idea.
How RA 9513 Is Implemented: DOE, ERC, Meralco, and BIR
RA 9513 is not self-executing. Four government bodies each have a defined role in turning the law’s provisions into practical outcomes for solar customers in the Meralco franchise area.
DOE
Department of Energy
Sets policy, issues implementing rules, maintains the registry of RE developers and installers, and monitors compliance. DOE accreditation confirms compliance with RA 9513 installation standards. SolarPro Install is DOE-accredited.
ERC
Energy Regulatory Commission
Administers the Net Metering Program mandated by Section 10 of RA 9513. Sets the rules for how Meralco must implement net metering, including application processes, billing mechanisms, and installer accreditation. The ERC Advisory dated September 22, 2025 is the latest regulatory update. SolarPro Install is ERC Net Metering accredited.
MRL
Meralco as 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.
BIR
Bureau of Internal Revenue
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 to all eligible equipment components in every project.
The Net Metering Provision: Section 10 of RA 9513
Section 10 of RA 9513 is the specific provision that created the net metering mandate. Understanding how net metering works for Meralco customers requires knowing what Section 10 legally requires of Meralco — and what it legally guarantees to you as a solar customer.
Mandatory Acceptance
Distribution utilities are required to accept net metering applications from qualified end-users with compliant RE 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. 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 kW 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 ERC 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, building on the ERC Advisory dated September 22, 2025. These four changes strengthen protections for solar customers and affect how the Meralco net metering application process in the Philippines is administered going forward.
NEW
Credits Become Mandatory Carry-Over
Current rule: credits “may” be banked and rolled over. Proposed amendment changes this to “shall” — making credit carry-over a mandatory entitlement. 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.
NEW
REC Meter Is Voluntary
The REC 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 based on installed capacity and capacity factor.
NEW
DIMC Fee Capped at ₱3,000 for Residential
The ERC Advisory dated September 22, 2025 confirmed that the DIMC fee for residential net metering customers shall not exceed ₱3,000. This protects homeowners from inflated meter replacement charges.
