Solar panels in the Philippines are sold through dedicated solar companies, major hardware retailers, and online marketplaces. The most reliable route for most homeowners is buying directly from an installer that handles everything from panels to permitting, but you have options depending on your budget and how hands-on you want to be.
Dedicated Solar Installers
The Philippines has a growing number of companies that specialize in residential and commercial solar. These firms sell panels, inverters, and mounting hardware as a package, and most handle design, installation, permitting, and net metering applications. The major national players include Solar Philippines, Solenergy Systems, Solaric, and Helios Solar Energy Corporation. Trina Solar, a global manufacturer, also has a substantial presence in the Philippine market and supplies high-efficiency panels to local installers.
Buying from a dedicated installer is the most common path for homeowners. You typically get a site assessment, a system designed for your roof and electricity usage, professional installation, and help filing your net metering application with your utility. Most of these companies operate primarily in Metro Manila but serve clients in Cebu, Davao, and other urban centers either directly or through regional partners. Solaric, for example, offers Tier 1 solar panels with product warranties ranging from 10 to 25 years, while inverters typically carry a 5-year warranty.
Hardware Stores and Retail Chains
If you prefer to shop in person or want to compare panel brands yourself, large hardware and home improvement stores carry solar panels and DIY solar kits. Stores like Home Depot stock solar panel kits with in-store availability and free ship-to-store pickup. Wilcon Depot and ACE Hardware locations sometimes carry individual panels, charge controllers, and small off-grid kits suited for basic setups or rural use. The selection at retail chains tends to lean toward smaller systems and individual components rather than full residential installations, so these are better suited for simple projects or for buyers who already have an installer lined up.
Online Marketplaces
Lazada and Shopee both list solar panels from Philippine-based and international sellers, often at lower upfront prices than installer packages. You can find individual panels, small off-grid kits, charge controllers, and inverters. The trade-off is that you handle installation yourself or hire a separate electrician, and warranty claims can be harder to resolve through third-party marketplace sellers. For anyone planning a full rooftop system, online purchasing works best when you already know the exact specifications you need and have a licensed electrician to do the installation.
On-Grid vs. Off-Grid: What It Costs
Before you buy, it helps to understand the two main system types, because they affect both where you shop and how much you spend. On-grid systems connect to your utility (like Meralco) and let you offset your electric bill. Off-grid systems use batteries to store power independently. Hybrid systems combine both, giving you grid connection plus battery backup during brownouts. A standard on-grid system will not provide power during a brownout; you need a hybrid or off-grid inverter for that.
Here are realistic 2025 price ranges for residential systems in the Philippines:
- 3 kW on-grid: ₱165,000 to ₱235,000
- 3 kW off-grid: ₱250,000 to ₱350,000
- 5 kW on-grid: ₱280,000 to ₱380,000
- 5 kW off-grid: ₱320,000 to ₱450,000
- 10 kW on-grid: ₱420,000 to ₱600,000
- 10 kW off-grid: ₱600,000 to ₱850,000
The price gap between on-grid and off-grid widens as systems get larger. Batteries alone can add ₱80,000 to ₱300,000 to any system. Off-grid setups also require a charge controller, a battery management system, and additional wiring, all of which increase both cost and installation complexity. For most homeowners connected to the grid, an on-grid or hybrid system offers the best value.
Financing Options
You don’t necessarily need to pay the full amount upfront. BPI offers a Solar Mortgage program with two options: a housing loan top-up starting at ₱400,000 with terms up to 20 years (if you already have an existing BPI housing loan with at least ₱400,000 paid up), or a multi-purpose loan using your car as collateral starting at ₱200,000 with terms up to 5 years, which carries a lower interest rate than a personal loan.
Pag-IBIG Fund members can also finance solar panel installation through a housing loan extension, covering up to ₱500,000 for solar installation on your own home. The loan is secured by the residential property where the panels will be installed. You will need a housing loan application, updated tax declaration and receipts, a vicinity map, valid IDs, a certified true copy of title, and proof of income.
How Net Metering Works With Meralco
If you install an on-grid or hybrid system, net metering lets you send excess electricity back to the grid and receive credits on your bill. Meralco’s application process requires a few key documents: an application form, a Certification of Final Electrical Inspection from your local government unit, and a Net-Metering Agreement (which Meralco provides and does not need to be notarized). You will also pay a Certificate of Compliance application fee to the Energy Regulatory Commission, and a meter cost difference fee of up to ₱3,000 for the bi-directional meter that replaces your old one.
After you submit everything, Meralco conducts a Distribution Impact Study to assess how your solar installation affects the local grid. If upgrades are needed, an additional asset study follows. Once approved, Meralco installs your bi-directional meter, tests the interconnection, and energizes your system. Coordinating early with your LGU for the electrical inspection certificate is worth doing, since documentary requirements vary by municipality and delays at that step are common.
What to Look for in a Warranty
Solar panels come with two types of warranty. The product warranty covers manufacturing defects and physical failures, typically lasting 10 to 25 years depending on the brand and tier. The performance warranty guarantees that panels maintain a minimum power output over time. The industry standard is at least 80% to 84% of original output after 25 years, though premium brands guarantee 88% to 92% retention. Inverters, the component that converts DC power from your panels into AC power your home uses, usually carry a shorter warranty of around 5 years.
When comparing suppliers, ask specifically about both warranty types and whether the company handles warranty claims directly or passes them to the manufacturer. Local installers with established service teams are generally easier to work with if something goes wrong 10 years down the line than a marketplace seller who may no longer be operating.
