Solar Loan Monthly Cash Flow Test for Quezon City Homes
A practical go/no-go test: will estimated monthly solar savings cover your loan payment?
Last updated: July 2026 · Figures are typical Quezon City residential / light-commercial ranges and can move with equipment markets and Meralco rates.
Direct answer: require savings ≥ amortization before you stretch the tenor
A healthy solar loan cash-flow test for Quezon City homeowners is simple: estimated average monthly Meralco savings should meet or beat the monthly amortization after a conservative haircut (plan at 70–85% of brochure savings). If the loan payment is larger than realistic savings, you are financing lifestyle stretch — not bill replacement. Build savings from size-by-bill and payback; build payments from bank quotes in the financing guide.
Inputs you need
- 12-month average bill and kWh
- Proposed kWp and itemized turnkey price
- Down payment % and tenor (e.g., 24–60 months)
- Indicative interest / add-on assumptions from the lender
- Fixed Meralco charges you will still pay
Worked sketch
| Input | Example | Comment |
|---|---|---|
| System price | ₱320,000 | 5–6 kWp class |
| Down payment | 20% (₱64,000) | Liquidity check |
| Amount financed | ₱256,000 | Bank/dealer loan |
| Est. monthly savings | ₱7,000–₱9,000 | After haircut |
| Target max amortization | ≤ savings | Cash-flow rule |
Exact amortization depends on product. If a 60-month quote prints ₱6,500/month and your conservative savings are ₱7,500, cash flow can work. If amortization is ₱10,000 against ₱6,000 savings, shrink kWp, raise down payment, or wait — do not hope summer bills alone will save the model every month.

Cash still wins total cost for many households. Loans win access. Leases remain uncommon for PH residential — lease vs loan vs cash. Decade framing: solar vs 10 years of Meralco.
Frequently asked questions
Should I finance batteries too?
Only if resilience is the goal and cash flow still clears. Batteries rarely pass a pure bill-savings loan test — when to add batteries.
