Solar Financing Calculator (Philippines)
Compare the real ways to finance a solar system — GSIS Ginhawa, Pag-IBIG, a bank loan, or 0% installer installment — on monthly payment and total interest.
How solar financing works in the Philippines
Most homeowners don’t pay cash. The four common routes are theGSIS Ginhawa Solar Energy Loan (government employees, 5% p.a., up to ₱500,000), the Pag-IBIG Multi-Purpose Loan(10.5% p.a., capped at your savings), a bank solar loan(8-12% p.a. over 3-5 years), and installer 0% installment(usually 12 months). Pick a route above to see the monthly payment and what the interest adds over the term.
Full detail on each option, requirements, and how to qualify is in the solar loan options guide, the GSIS Ginhawa guide, and the Pag-IBIG solar loan guide. Not sure what your system should cost first? Start with the solar panel calculator.
Solar financing FAQ
Frequently asked questions
What is the cheapest way to finance solar in the Philippines?
For government employees, the GSIS Ginhawa Solar Energy Loan is the cheapest at 5% per annum over 5 years for up to ₱500,000. Installer 0% installment plans are effectively free but usually only run 12 months. Bank solar loans run 8-12% per annum, and the Pag-IBIG Multi-Purpose Loan is 10.5%.
How much is the GSIS solar loan monthly payment?
A ₱500,000 GSIS Ginhawa Solar Energy Loan at 5% per annum over 60 months works out to about ₱10,417 a month, with no service fee. The calculator computes the monthly payment for any amount up to the ₱500,000 ceiling.
Can I use a Pag-IBIG loan for solar?
Yes, through the Multi-Purpose Loan (MPL), which you can spend on home improvements like solar. It is capped at up to 90% of your Pag-IBIG savings, so it usually covers part of the system, not all of it, at 10.5% per annum over 12, 24, or 36 months.
Does financing change how fast solar pays back?
It spreads the cost so your monthly solar savings can offset part of the loan payment, but the interest adds to the total you pay. A cash purchase has the fastest payback; financing trades a higher total cost for a smaller upfront outlay.
How accurate are these numbers?
The monthly payment math is exact amortization for the rate and term shown. The rates are current 2026 figures, but bank rates vary by borrower and the Pag-IBIG amount depends on your savings, so treat the totals as close estimates and confirm with the lender.
