Panel Funding: Pro Insights for PH Projects
In the Philippine solar industry, the most common question isn’t "Does it work?"—we know it works. The question is, "How do I pay for it?"
For years, the standard answer was bluntly elitist: "Cash is king." And mathematically, that remains true. Paying ₱300,000 upfront for a 5kW system yields the fastest ROI (typically 4–5 years) because you aren't paying interest to a bank.
But in 2025, telling middle-class Filipino homeowners or cash-flow-sensitive SMEs to "just pay cash" is bad advice. It ignores the sophisticated financial tools now available that allow you to go solar with minimal upfront capital.
"Panel Funding" in the Philippines isn't about finding a magical government grant (those don't exist for individuals). It is about structuring leverage. It’s about using other people's money (OPM) to build an asset that pays for itself.
Here is the practitioner’s guide to financing solar projects in the Philippines, from residential rooftops to commercial warehouses.
The "Positive Cash Flow" Rule
Before you sign any loan document, you must understand the Golden Rule of Solar Financing: Monthly Savings > Monthly Amortization.
If your solar system saves you ₱8,000 a month in electricity bills, and your loan payment is ₱6,000 a month, you are "cash flow positive" from Day 1. You effectively got a free system and put ₱2,000 in your pocket.
If the loan payment is ₱10,000, you are "cash flow negative." You are paying ₱2,000 a month for the privilege of owning the system. This isn't necessarily bad (you are building equity), but it changes the financial dynamic.
Residential Track 1: The Pag-IBIG "Hack"
For the average Filipino employee, the Pag-IBIG Fund (HDMF) is the most underutilized tool for solar adoption.
Most people think Pag-IBIG is only for buying a house and lot. They forget about the Home Improvement Loan.
The Scope: Solar panel installation is explicitly listed as a valid purpose for home improvement.
The Rates: Pag-IBIG offers some of the lowest interest rates in the market (starting at around 5.75% per annum for 1-year repricing).
The Term: Unlike a personal loan which is capped at 3–5 years, Pag-IBIG allows you to stretch payments over 20 or even 30 years.
The Pro Insight: By stretching the term to 10 or 15 years, you can drive the monthly amortization way below your monthly electricity savings. You turn your roof into a cash-generating asset immediately. The downside? The paperwork is legendary. Expect a 1–2 month processing time and strict collateral requirements (your land title).
For a step-by-step breakdown of the requirements, consult our guide to the Pag-IBIG solar loan.
Residential Track 2: The "Green" Mortgage
If you don't have the patience for government paperwork, the private banking sector has woken up. In 2024 and 2025, major banks like BPI, BDO, and Security Bank launched aggressive "Green Energy" or "Solar Mortgage" products.
These are not standard personal loans (which have high interest rates of 12–24%). These are collateralized loans tied to your property.
Security Bank: Offers a "Solar Mortgage" specifically for top-up or renovation, often with promo rates around 7% to 8% fixed for the first few years.
BPI: Has integrated green upgrades into their housing loan top-ups, allowing you to use your existing collateral to fund the solar mortgage.
The Strategy: If you already have a mortgage with these banks, apply for a "Top-Up." Since they already hold your title, the approval is faster. You are essentially refinancing your home to add a power plant.

Residential Track 3: Vendor Financing (0% Interest)
For smaller systems (3kW to 6kW), bank loans might be overkill. This is where Vendor Financing shines.
In the competitive 2025 market, top-tier installers have partnered with credit card companies to offer 0% interest installment plans for 12, 24, or even 36 months.
The Math: A ₱250,000 system spread over 24 months is roughly ₱10,400 per month.
The Catch: Verify the "Cash Price" vs. the "Card Price." Some installers add a 5–10% markup to cover the bank transaction fees. Always ask for the straight cash discount first to see the real "cost of credit."

Commercial Track: The Capex vs. Opex War
For business owners—factory managers, cold storage operators, school administrators—the game is different. You are dealing with systems worth ₱5 Million to ₱50 Million.
You have two main paths: Capex (Ownership) or Opex (Leasing/PPA).
Path A: Capital Expenditure (Capex)
You buy the system using company cash or a commercial loan.
Pros: You own the asset. You claim the depreciation (tax shield). You keep 100% of the savings (often ₱7–₱9 per kWh avoided cost).
Cons: It hits your balance sheet. It depletes cash reserves.
Funding: Banks like BDO offer "Sustainable Energy Finance" (SEF) programs that are more lenient than standard commercial loans.
Path B: Solar Leasing & PPAs (Opex)
This is the "Zero Cash Out" model.
The Mechanism: A third-party investor installs the solar plant on your roof for free.
Solar Lease: You pay a fixed monthly "rent" for the equipment.
Power Purchase Agreement (PPA): You pay for the power generated, usually at a discount to the grid rate (e.g., if Meralco is ₱12/kWh, you pay the solar company ₱9/kWh).
The Verdict: You save less money overall compared to owning it, but you preserve your capital for your core business.

The "Hidden" 12% Grant: VAT Zero-Rating
I mentioned there are no cash grants. That is true. But there is a tax grant that effectively functions as a 12% discount.
Under Republic Act 9513 (The Renewable Energy Act) and recent BIR clarifications, the sale of renewable energy components and services by DOE-accredited suppliers is VAT Zero-Rated.
The Scenario: On a ₱1,000,000 project, the VAT would normally be ₱120,000.
The Funding: By working with a legitimate, BOI-registered installer, you legally avoid paying this ₱120,000. That is essentially a government subsidy "funding" 12% of your project.
Warning: Many "colorum" installers will not offer this because they are not registered with the Board of Investments (BOI). They will charge you VAT (or hide it) and pocket the difference.
Ensure you are claiming this benefit by reading our guide to VAT zero-rating availability.
The "Net Metering" Cash Flow Factor
Finally, you cannot calculate your funding needs without factoring in Net Metering.
Financing is about monthly payments. Net Metering provides the monthly income to make those payments.
The Shift: Without Net Metering, your savings are limited to your daytime usage. With Net Metering, your system earns credits even when you aren't home (weekends, holidays).
The Impact: These credits lower your remaining bill, freeing up more of your household income to service the loan.
We have seen clients whose Net Metering credits in the summer months completely covered their loan amortization for that period.
Conclusion: Leverage is Strategy
Solar is a unique asset class. It is a home improvement that pays you back. It is a factory upgrade that lowers opex.
If you have the cash, pay cash. But if you don't, do not wait five years to save up. In those five years, you will have paid Meralco hundreds of thousands of pesos that you will never get back.
Use the banks. Use Pag-IBIG. Use the tax incentives. Funding is available for those who treat solar not as a purchase, but as a project.
