RA 9513: The Renewable Energy Act — What Solar Homeowners Need to Know
Republic Act 9513 is the legal foundation for solar energy in the Philippines. It gives you the right to install solar, mandates net metering, and protects you from discriminatory utility practices. Here is what it actually means for your home.
What is Republic Act 9513?
Republic Act 9513, officially titled the Renewable Energy Act of 2008, is the primary legislation governing renewable energy development and use in the Philippines. It was signed into law on December 16, 2008 and covers solar, wind, hydro, ocean, biomass, and geothermal energy.
For residential solar homeowners, the most important part of RA 9513 is Section 10, which establishes the net metering program and requires all distribution utilities — including Meralco — to allow qualified renewable energy system owners to connect to the grid and receive credits for excess generation.
The detailed rules for residential net metering are spelled out in ERC Resolution No. 9-2013, issued by the Energy Regulatory Commission — the government body responsible for regulating electricity rates and services in the Philippines.
Key provisions that protect you as a solar homeowner
Net metering is your right
Section 10 of RA 9513 mandates that all distribution utilities — including Meralco — must offer net metering to any customer with a qualified renewable energy system. They cannot refuse your application without legal cause.
Buyback rate is regulated
The Energy Regulatory Commission (ERC) sets the minimum buyback rate for exported solar energy through ERC Resolution No. 9-2013. Distribution utilities cannot set their own rate below the ERC-mandated level.
Application processing is time-limited
Distribution utilities must process net metering applications within 10 working days under DOE DC2026-01-00012 (April 2026). Under the February 2026 Joint Memorandum Circular, LGUs must now issue electrical permits within 3 working days and CFEIs within 3 working days — with deemed approval if they fail to act. Notarization of the net metering agreement is no longer required and electronic signatures are now accepted under the September 2025 ERC Advisory.
No discrimination against solar customers
RA 9513 prohibits distribution utilities from imposing discriminatory charges or conditions on renewable energy system owners that are not applied to conventional electricity customers.
Your rights as a solar customer
How to file a complaint with the ERC
If Meralco or your distribution utility violates your net metering rights under RA 9513, you can file a complaint with the Energy Regulatory Commission at erc.gov.ph or visit their office at the Pacific Center Building, San Miguel Avenue, Pasig City. TrueSouth can assist you in preparing and filing a complaint if needed.
ERC Resolution No. 9-2013 — Key provisions
ERC Resolution No. 9-2013 is the implementing regulation that translates RA 9513's net metering mandate into specific, enforceable rules for distribution utilities and solar customers.
Timeline — Solar legislation in the Philippines
RA 9513 signed into law
Republic Act 9513, the Renewable Energy Act of 2008, is signed by President Gloria Macapagal-Arroyo. It establishes the legal framework for renewable energy development, including solar, wind, hydro, biomass, and geothermal.
Implementing Rules and Regulations issued
The Department of Energy (DOE) issues the Implementing Rules and Regulations (IRR) of RA 9513, providing detailed guidelines for renewable energy developers, system owners, and distribution utilities.
ERC Resolution No. 9-2013 — Net Metering Rules
The Energy Regulatory Commission issues the Rules Enabling the Net Metering Program for Renewable Energy, establishing the specific procedures, rates, and requirements for residential and commercial solar net metering.
Meralco begins accepting net metering applications
Following ERC orders, Meralco launches its net metering program, allowing residential customers with rooftop solar PV systems to export excess generation to the grid and receive bill credits.
Green Energy Option Program (GEOP)
DOE launches GEOP allowing large electricity users to source power from renewable energy suppliers, complementing the existing net metering program.
ERC amends net metering rules — expanded scope
The ERC amends ERC Resolution No. 9-2013, expanding net metering eligibility to a broader range of commercial and industrial customers and clarifying technical interconnection requirements. The 100 kW ceiling for qualified generating capacity (measured as inverter AC output capacity, per RA 9513 Section 10) is affirmed.
ERC amends net metering rules — September 2025
The ERC issues amended rules simplifying the net metering program: credit banking and rollover expanded, credits now transferable to new property owners on sale, meter replacement cost capped at ₱3,000, notarization no longer required, and electronic signatures accepted.
Joint Memorandum Circular — February 2026
DOE, DILG, and DPWH issue a Joint Memorandum Circular mandating LGUs issue electrical permits within 3 working days and CFEIs within 3 working days — with deemed approval if they fail to act. DOE Supplemental Policy grants qualified end-users ownership of Renewable Energy Certificates (RECs) for trade in the Renewable Energy Market.
Frequently asked questions
Does RA 9513 apply to all solar PV systems or only large ones?
RA 9513 and its net metering provisions apply to all qualified renewable energy systems up to 100 kW of inverter AC output capacity (per Section 10 of the Act — the cap is on inverter capacity, not DC panel wattage). This covers virtually all residential installations, which are typically 3–15 kW inverter capacity.
What happens if Meralco refuses my net metering application?
If Meralco refuses your application without valid technical grounds, you have the right to file a complaint with the Energy Regulatory Commission (ERC). The ERC can compel Meralco to accept your application and may impose penalties for non-compliance.
Is the buyback rate fixed or does it change?
The buyback rate (approximately ₱6.00/kWh) is based on Meralco's blended generation rate, which changes periodically as Meralco's power supply agreements are renegotiated. The ERC publishes updated rates. Your net metering agreement specifies how rate changes are applied.
Do I need a permit from my local government to install solar?
Yes. A building or electrical permit from your Local Government Unit (LGU) is typically required before installation and is one of the documents needed for the Meralco net metering application. Your installer handles this as part of the installation process.
Can I sell my excess solar credits for cash?
Credits cannot be converted to cash — they can only be applied against your electricity bill. Under the September 2025 ERC amendments (Resolution No. 15, Series of 2025), unused credits roll over indefinitely to future billing periods — there is no annual forfeiture. Credits can also be transferred to a new owner if you sell your property, subject to a written agreement from the original owner.
Does RA 9513 provide any tax incentives for solar?
Yes. RA 9513 provides VAT exemption on the sale of power from renewable energy sources and income tax holidays for registered renewable energy developers. For residential installations, the main financial benefit is the net metering credit rather than direct tax incentives.
How TrueSouth ensures full RA 9513 compliance
Every TrueSouth installation is designed and executed to meet all requirements under RA 9513, ERC Resolution No. 9-2013, and the Philippine Electrical Code.
