Homeowners in Ozamiz and homeowners in Cebu ask the same question: how long until my solar system pays for itself? The honest answer is that both markets look great, but the math is slightly different — and in some scenarios Ozamiz and the rest of MOELCI II territory comes out ahead. Here is the side-by-side, with the actual tariff and production numbers for 2025.
The shortest payback depends less on the city and more on three specific numbers: tariff, peak sun hours, and your monthly bill.

The three numbers that drive payback
Payback period is not a function of how good the installer is. It is a function of three inputs:
- Your tariff (PHP per kWh). The higher this is, the more each self-generated kWh saves you. Above PHP 11/kWh is the threshold where solar becomes a no-brainer.
- Your local peak sun hours. The more sun hours, the more kWh your system produces per kW installed. Mindanao and the Visayas both sit in the 5 to 6 hour range.
- Your monthly consumption. The bigger the bill, the more absolute savings per month, and the faster you recoup in nominal terms.
Both MOELCI II (Ozamiz, Tangub, MOELCI II municipalities) and VECO (Cebu City, Mandaue, Lapu-Lapu, and the metro franchises) are above PHP 11/kWh residential. Both get 5 to 6 peak sun hours a day. The difference is in the tariff rate, the rate of annual increase, and how stable the grid is.

The 5 kW payback math, side by side
Assume an identical 5 kW on-grid system producing 8,000 kWh per year, installed at PHP 280,000 in both cities. Here is what payback looks like in 2025:
Cebu (VECO residential, PHP 11.50/kWh, 4 to 5% annual increase)
- Year 1 savings: 8,000 kWh x PHP 11.50 = PHP 92,000.
- Year 2 savings: 8,000 kWh x PHP 12.00 = PHP 96,000.
- Year 3 savings: 8,000 kWh x PHP 12.55 = PHP 100,400.
- Cumulative end of year 3: PHP 288,400 — payback achieved in year 3.
Ozamiz (MOELCI II residential, PHP 11.20/kWh, 5 to 6% annual increase)
- Year 1 savings: 8,000 kWh x PHP 11.20 = PHP 89,600.
- Year 2 savings: 8,000 kWh x PHP 11.85 = PHP 94,800.
- Year 3 savings: 8,000 kWh x PHP 12.55 = PHP 100,400.
- Cumulative end of year 3: PHP 284,800 — payback achieved in year 3.
Both cities hit payback in roughly the same window: 3 to 3.5 years on a 5 kW system at 2025 tariff. Cebu's slightly higher starting rate is offset by slightly slower annual increase. The systems are essentially tied.

Where Ozamiz pulls ahead
Ozamiz and MOELCI II territory have a few structural advantages that become visible after year 5:
- Higher annual tariff escalation. MOELCI II has raised rates 5 to 6 percent annually since 2022, while VECO has held closer to 4 percent. By year 10, MOELCI II rates are 15 to 20 percent higher than VECO's, which makes every self-generated kWh worth more.
- Lower net-metering credit expiry pressure. MOELCI II has been more lenient on credit carry-forward and payout timing. VECO credits historically expire or roll over inconsistently.
- Better afternoon sun in the bay-side municipalities. Tangub and Ozamiz get clearer afternoons than Cebu City, which catches afternoon clouds from the western mountain range.
Net effect: a 5 kW system in Ozamiz returns about 8 to 12 percent more lifetime savings than the same system in Cebu City, on a 25-year horizon. The gap widens after year 6.

Where Cebu pulls ahead
To be fair, Cebu has its own advantages:
- Lower per-watt install cost. Cebu's installer market is more competitive. A 5 kW system in Cebu City may quote PHP 230,000 where the same system in Ozamiz is PHP 260,000 to 280,000.
- Faster net-metering. VECO has approved net-metering in 6 to 10 weeks in 2025. MOELCI II is 8 to 14 weeks. The difference is the upfront time cost of capital tied up before the system is energized.
- More installer choice. More installers means more competitive bids. In Ozamiz you may have 3 to 5 serious solar companies to choose from. In Cebu you have 30.
These advantages shorten the Cebu payback by 1 to 3 months in practice, even if the underlying savings math is similar.

The honest answer: which city recoups faster?
For a 5 kW on-grid system in 2025, payback is 3 to 4 years in both Ozamiz and Cebu. The difference is in the noise, not the signal. If you are picking a home based on which market is better for solar, that is the wrong decision — pick the home based on where you want to live.
If you already own the home and are deciding whether to install now: do it. The longer you wait, the more you pay in future electricity at MOELCI II or VECO's projected rate increases. Every year of delay is roughly PHP 90,000 to 110,000 in foregone savings on a 5 kW system.
The market that does recoups noticeably slower is MOELCI I's far-flung municipalities — Calamba, Don Victoriano Chiongbian, Sapang Dalaga — where lower tariffs and remote-install surcharges stretch payback to 5 to 6 years. Still worthwhile, just slower.
Frequently asked questions
Is solar cheaper in Cebu or in Ozamiz?
Per-watt installed cost is slightly lower in Cebu because of installer competition. A 5 kW on-grid system is around PHP 230,000 to 280,000 in Cebu and PHP 250,000 to 300,000 in Ozamiz. The gap closes when you account for MOELCI II faster tariff escalation, which makes lifetime Ozamiz savings 8 to 12 percent higher.
How many years until solar pays for itself in MOELCI II?
For a 5 kW on-grid system in Ozamiz or Tangub in 2025, payback is 3 to 4 years. For a 3 kW system, 4 to 5.5 years. For a hybrid system with battery, add 1.5 to 2.5 years to the on-grid payback.
Does peak sun hours differ between Cebu and Mindanao?
Not significantly. Both get 5 to 6 peak sun hours per day. Cebu City tends to be slightly cloudier in the afternoon due to the western mountains. Ozamiz and Tangub have clearer afternoons but a bit more morning fog over the bay.
