For decades, the Philippine energy landscape was defined by centralized monopolies and the dominance of distribution tycoons—a structure that persisted even after the Electric Power Industry Reform Act (EPIRA) of 2001. This centralization created a stark geographic divide: while metropolitan hubs enjoyed relatively consistent power, the rest of the archipelago endured chronic instability, frequent blackouts, and an unreliable energy supply.
Today, however, the industry is undergoing a transformative shift. Substantial regulatory developments are dismantling this centralized model in favor of decentralization. By pivoting toward renewable energy, the Philippines is moving beyond the search for cheaper power to address a fundamental national need for energy equity and resilience. This transition offers a “golden opportunity” to leverage the country’s tropical abundance, turning a history of systemic instability into a future of energy sovereignty.
Central to this decentralization is Solar Photovoltaic (PV) technology. Unlike traditional power plants that rely on combustion, Solar PV systems use semiconductor cells to convert the Philippines’ abundant sunlight directly into electricity. Because these systems are modular—ranging from a few panels on a residential roof to thousands of acres in a utility-scale solar farm—they allow power to be generated exactly where it is consumed. This reduces the country’s reliance on aging long-distance transmission lines and helps stabilize the local grid.
The Philippines is uniquely positioned as a premier location for such development. Geographically situated near the equator, the archipelago receives an average irradiance of 4.5 to 5.5 kWh/m² daily, a level far superior to many global leaders in renewable energy. To capitalize on this, the National Renewable Energy Program (NREP) 2020-2040 has set an ambitious target of a 35% renewable energy share by 2030, increasing to 50% by 2040.
Supported by the RE Act of 2008 and the Energy Virtual One-Stop Shop (EVOSS) Act, the Department of Energy (DOE) has effectively streamlined the entry process for new players. For investors, this expanding industry offers multiple entry points—from utility-scale infrastructure for consortiums to high-yield “Net Metering” setups for homeowners.
Large Scale Solar PV Farms
Solar PV farms, as the name infers, are ideally developed in agricultural lands (or on the surface of water) where sunlight is abundant and constantly shining. For those that have capital and are interested in developing large-scale projects and big returns, investors might consider establishing solar farms and become a generating company or Genc. Solar PV farms are capable of producing large amounts of energy, which may be sold directly to the national grid or to distribution utilities serving a certain franchise area.
To develop a solar farm, investors must first establish a corporation organized under Philippine law and register as a RE developer. Thereafter, they must process the necessary documents and registration to secure permits such as, but not limited to, a Solar Energy Operating Contract, Environmental Compliance Certificate (ECC), Technical Studies, Land Use Permit, and Certificate of Compliance. Through EVOSS, the necessary information and required permits are now streamlined under one digital submission platform, making the process easier and less bureaucratic.
Registered and authorized Solar PV Developers/Generation Company have the option to connect directly to the national grid, sell to the wholesale markets or to distribution utilities, sell directly to contestable consumers, embed itself with a distribution utility, install a battery energy storage system (BESS), employ self-generating facilities (SGFs), and other less commonly employed options.
a. Connection to Distribution Utilities
If the Solar PV Developer/Generation Company opts to supply to distribution utilities, the DOE generally mandates that the parties enter into a competitive selection process to ensure that the agreement is the least costly to consumers.
The Solar PV Developer/Generation Company may either directly connect the system to the Grid either through the interconnected transmission lines, substations and related facilities, or embed to the Distribution Utility’s distribution system. Either of these methods generally require a Power Supply Agreement (PSA) and Certificate of Compliance (COC). With direct connection, however, the process may take longer since the Generation Company will be required to secure a connection and services agreement, a point-to-point application and application with Wholesale Electricity Spot Market (WESM), thus requiring more process and will take longer before reaching commercialization.
b. Wholesale Electricity Spot Market
The Solar PV Developer/Generation Company may also choose to just sell in the retail market through the WESM. This is done by entering into a connection agreement with NGCP and submitting an application through the IEMOP Central Registration Board. Under this arrangement, the company may sell their electricity directly to the grid, enabling them to sell their electricity to contestable consumers nationwide. The disadvantage with relying on sales to the WESM is that it subjects the electricity to market price volatility making income erratic and the price of the electricity generated dependent on market conditions.
c. BESS
Solar PV Developers and Generation Companies should also consider installing Battery Energy Storage Systems or BESS into their plans when investing in solar energy. BESS allows solar developers to store energy generated by their solar PV systems during times of low demand and discharge these when demand peaks or during times of emergency or fluctuations. BESS may be incorporated in all kinds of set-ups, from utility-sized solar farms to mitigate fluctuations, to small residential buildings and establishments to serve as back-up power, particularly for those in off-grid areas.
BESS may be established as a stand-alone unit or integrated into generation facilities that can be either renewable or non-renewable, with the corresponding permits such as COC dependent on the type of set-up. This also means that the analogous connection and operational requirements, such as compliance with the standards mandated under Philippine Distribution Code and Philippine Grid Code shall also apply to the BESS.
d. Self-generating facility
Self-generating facilities (SGF) are facilities that are installed but no intention of supplying for outside consumers or establishments, nor will the distribution utility claim any excess. They are a “zero-export” system. Apart from the COC, ECC and applicable LGU permits, a SGF does not have substantial permits since it does not affect the market or third-party consumers. This is the best option for buildings that will 100% use up the amount of energy being produced by the SGF.
e. Green Energy Auction Program (GEAP)
The GEAP is a competitive bidding mechanism managed by the DOE to procure large-scale RE capacity. GEAP is designed for RE Developers to secure long-term, 20-year PSA at a fixed, competitive rate. Developers bid a Green Energy Tariff (GET) which is the price per kWh they are willing to accept for their power. After which, the winning bidders are basically guaranteed that their generated power will be paid for, often funded through a GEA-All surcharge on all electricity bills.
Notably, these modes of supplying power to consumers are not mutually exclusive. A developer may, for example, participate in both the GEAP and the WESM, or embed with a distribution utility while also selling to the grid. The legal and regulatory framework allows this level of flexibility, enabling solar developers and generating companies to structure business models that best align with their strategic and commercial interests.
Rooftop Solar PV Systems
Another option investors might take is to install rooftop solar PV systems. These may be installed in residential, commercial, or industrial establishments, depending on the capital and commercial arrangement preferred by the investors. Rooftop Solar PV Systems and the business models available per developer depends on the capacity of each system, specifically: (1) up to 100 kW, (2) greater than 100 kW up to 1 MW, or (3) more than 1 MW.
a. Up to 100kW
For Rooftop Solar PV Systems that do not exceed 100 kW, the common track is to enter a Net-Metering Program with the distribution utility. Net metering is a program that allows electricity consumers who install renewable energy systems with a maximum capacity of 100kW to export excess electricity produced to the distribution grid and receive credits on their power bills based on the amount exported. Introduced in the Renewable Energy Act of 2008, it is designed to promote energy independence to small-scale energy users, to reduce grid demand during peak hours, and to accelerate the adoption of renewable energy, including the use of solar panels.
Under the net metering program, a solar PV system is connected to both the customer’s electrical system and the distribution utility’s network using a bi-directional meter to record both imported and exported electricity. Excess energy produced by the solar PV that is not used by the customer is sold back to the distribution utility and a customer gets a rebate or credit based on the amount of energy sold. Meanwhile, at times when the solar PV system cannot meet the consumer’s electricity demand, they can use electricity sourced from the distribution utility.
Recent policy enhancements such as the introduction of the Amended Rules on Net-Metering have significantly improved the financial attractiveness of net metering, particularly for small-scale investors or adopters of renewable energy including solar panels. Starting 2025, excess energy credits can now be carried forward indefinitely rather than expiring after one year, allowing system owners to maximize long-term savings and earn and collect credits that can be stored indefinitely or passed on. This allows property owners to include these credits as either perks or additional value for the property where the rooftop solar system is located once it is sold in the secondary market.
Additionally, the Rules have made it mandatory for distribution utilities to post the net-metering programs, application forms, processes, dedicated cellphone contact numbers for net-metering, and related processes. They shall also publish the hosting capacities in a typical distribution transformer (kWac) basis quarterly.” This makes it easier for parties interested to join the program to find up-to-date information wherever they are in the Philippines.
On 1 February 2026, through a Joint Memorandum Circular No. 001 series of 2026, by the DOE, in partnership with the Department of the Interior and Local Government (DILG) and the Department of Public Works and Highways (DPWH), which streamlines rooftop solar deployment in the Philippines by enforcing a 3-day permit approval rule for LGUs and enabling automated approval if deadlines are missed.
Under the new framework, applications are now deemed automatically approved if these timelines are not met, allowing homeowners and businesses to proceed using proof of submission and payment. The circular also promotes digitalization by recognizing electronic signatures and limiting requirements to essential safety and technical documents, reducing delays caused by physical paperwork and redundant processes.
Beyond faster approvals, the policy strengthens the financial case for rooftop solar. Participants can now retain ownership of Renewable Energy Certificates (RECs), which may be traded in the Renewable Energy Market to generate additional income. The introduction of multi-site or aggregated metering also enables businesses to share solar credits across multiple facilities under the same distribution utility, maximizing the value of excess generation.
With only about 157 MW of net-metered capacity recorded as of 2025, the government aims to accelerate adoption, standardize processes across more than 1,600 LGUs, and enhance energy security through decentralized power generation. Ultimately, JMC 001-2026 signals a strong commitment to democratizing energy in the Philippines—making rooftop solar faster, simpler, and more financially rewarding for households and enterprises alike.
b. greater than 100 kW up to 1 MW
In cases where the rooftop solar PV system is more than 100 kW but not more than 1MW, then a net-metering program can no longer be entered into for grid-tied systems. Rather, the rules on Distributed Energy Resources shall apply.
Investors under this program have several options for their business model. They can:
- Retain ownership of the system and sell the energy produced to the end-user
- Retain ownership of the system and transfer it to the end user after the terms of their agreement
- Enter into an agreement to lease out the system to the end user who will also acquire all the energy produced during the term of the agreement.
- Enter into an agreement where they own the system, but the operation and maintenance will be with a third-party.
This option is more common for industrial or commercial users like malls, factories, or warehouses. Securing a Commercial DER status allows you to operate as a “mini utility” for your own facility while legally exporting excess power to the grid.
Under the ERC Resolution, the requirements for authorizing a DER system includes, among others, paying the Distribution Utility to conduct a System Impact Study, submitting an application with the ERC, securing a COC, and entering into a connection agreement with the Distribution Utility. This is much more complicated than a net-metering program.
c. greater than 1 MW
For rooftop solar PV systems greater than 1MW the registration process and options are similar to solar PV farms, the only exception being is that these do not usually require environmental and land permits since the system is installed in commercial buildings rather than on agricultural land or lake. Since it is similar to solar PV farms, the options provided therein may also be employed.
Expanded Roof-Mounted Solar Program
In 2023, the DOE released the Expanded Roof-Mounted Solar Program which sought to promote and encourage the use and transition to solar energy and make available rooftops in the Philippines even more productive.
Under this program, the ERC stated different business models that the rooftop solar PV developer can employ regardless of the systems. These options mainly pertain to arrangements available to solar PV farms as aforementioned, such as, but not limited to, direct connection with distribution utilities, developing an SGF or BESS, entering into WESM, or GEAP, or a combination of the options provided herein.
Finally, the developer may also install a hybrid system through a BESS. The commercial or household developing a rooftop solar PV system may choose a hybrid system which includes a net-metering program/DER with BESS, or any zero-export system with BESS.
As the Philippines continues to push toward renewable energy, solar PV stands at the forefront as one of the most promising investment opportunities. With stronger regulatory support, streamlined permitting processes, expanded financial incentives, and its natural geographical advantage, the country is now in a prime position to welcome new investors and developers into the sector.
