A 5 kW solar system is the most common residential size we install in both Cebu and Ozamiz. The question we get from Misamis Occidental homeowners is always the same: how many kWh will it actually produce, and how does that compare to Cebu? The short answer: nearly identical. The longer answer is a month-by-month production table that shows exactly where the small differences fall.
Here are the real numbers.

The baseline: 5 kW at 5.5 PSH
A 5 kW solar array in Misamis Occidental produces roughly 27.5 kWh per day at 5.5 peak sun hours, before any system losses. Real-world losses from inverter efficiency, wiring, soiling, and temperature typically run 15 to 20 percent, so the net daily production is closer to 22 to 24 kWh.
Annual production: 8,000 to 8,800 kWh per year. Cebu produces essentially the same number. This baseline does not change between the two regions because the solar resource itself is equivalent at this latitude. The 5.5 PSH figure assumes reasonably clear skies. During amihan cloud cover in January or habagat storms in August, daily production can dip to 3 to 4 PSH equivalent, or roughly 15 to 18 kWh per day for a 5 kW system. Over the full year, those cloudy months average out against the dry-season peak, leaving you at the 5.5 PSH baseline.
Month-by-month production (Misamis Occidental)
Using a typical 5 kW system in Ozamiz or Oroquieta with south-facing panels at 10 to 15 degree tilt, the expected monthly production breaks down as follows:
- January: 600 to 650 kWh (cooler, partly cloudy)
- February: 700 to 750 kWh (drier, clearer)
- March: 800 to 850 kWh (dry season starts)
- April: 850 to 900 kWh (peak dry)
- May: 800 to 850 kWh (still dry, getting hotter)
- June: 650 to 700 kWh (rains begin)
- July: 600 to 650 kWh (peak rain)
- August: 600 to 650 kWh (peak rain)
- September: 650 to 700 kWh (rains tapering)
- October: 700 to 750 kWh (transitional)
- November: 700 to 750 kWh (transitional)
- December: 600 to 650 kWh (cooler, cloudy)
Annual total: approximately 8,200 to 8,800 kWh. The pattern is symmetric: dip in the wet months, peak in the dry months, with the average coming out to the 5.5 PSH baseline.

How Ozamiz compares to Cebu, month by month
The two regions track closely, with Ozamiz slightly ahead in the dry months and slightly behind in the wet months. In the dry season (March to May), Ozamiz is typically 5 to 10 percent above Cebu due to clearer skies and lower humidity. In the wet season (June to September), Ozamiz runs roughly equal to Cebu, with more intense but shorter rain events. In the cool months (December to February), Ozamiz runs 5 percent below Cebu due to slightly more cloud cover from the northeast monsoon.
Annual production difference: typically within 3 to 5 percent. For practical purposes, identical. The Ozamiz-Cebu production comparison is also useful when reasoning about system upgrades. If you have read about a Cebu household's solar experience in a forum or Facebook group, the production numbers you saw there are essentially transferable to Ozamiz with a small adjustment for the specific microclimate. Do not let anyone tell you that 'Mindanao gets less sun' and use that as justification for a larger, more expensive system. The data does not support that claim at this latitude.

What this means for net-metering offset
For a household consuming 500 kWh per month, the math works as follows. In January, production (600 to 650 kWh) minus consumption (500 kWh) yields a 100 to 150 kWh surplus exported to MOELCI II. In April, production (850 to 900 kWh) minus consumption (500 kWh) yields a 350 to 400 kWh surplus. In July, production (600 to 650 kWh) minus consumption (500 kWh) yields a 100 to 150 kWh surplus.
In every month, the 5 kW system produces more than the 500 kWh household consumes. The surplus exports to MOELCI II for net-metering credit at above PHP 11/kWh. The household's monthly bill drops to the minimum charge (often PHP 50 to PHP 200) for most of the year. For higher-consumption households (700 to 800 kWh/month), production still exceeds consumption from February to November, and only the December to January stretch may need grid top-up.

When the 5 kW system comes up short
Two scenarios where a 5 kW system is not enough for an Ozamiz home. First, very high consumption (1,000+ kWh/month) — usually a home-based business or large household with central air conditioning. The fix is to step up to 8 to 10 kW. Second, heavy shading — trees, neighboring buildings, or Mt. Malindang shadow can cut effective production 20 to 40 percent. Either trim the obstruction, relocate the array, or oversize the panel count to compensate.
For Ozamiz households considering a 5 kW system, the practical ceiling is around 700 kWh per month of consumption. Above that, you start seeing noticeable grid imports in the cloudier months, which is fine but increases your annual bill beyond the 'near zero' target. For consumption above 700 kWh/month, step up to 6 or 8 kW rather than oversizing the battery to cover the difference. For typical Ozamiz, Tangub, and Oroquieta households, 5 kW remains the right answer. It hits the 4 to 6 year payback window, offsets 70 to 80 percent of the bill, and leaves room for one or two future load additions.

Frequently asked questions
How much does a 5kW system produce on a cloudy day in Ozamiz?
A heavily overcast day in Ozamiz produces 20 to 40 percent of clear-sky output, so roughly 5 to 10 kWh for a 5 kW system. Light overcast produces 50 to 70 percent.
Does a 5kW system produce more in Ozamiz or in Cebu?
Annual production is within 3 to 5 percent. Ozamiz has a slight edge in dry months (March to May), Cebu has a slight edge in cool months (December to February). For payback purposes they are identical.
Will a 5kW system eliminate my MOELCI II bill?
For most households consuming 500 kWh or less per month, yes — the bill drops to the minimum monthly charge. For higher-consumption households, expect a small residual bill in the December to February stretch.
