Marikina, Metro Manila, NCR
A mixed residence-and-office rooftop in Marikina
A DOE-documented 11 kWp residence-and-office system recorded 15,930.3 kWh of annual output and an 83.5% performance ratio.
Documented project figures
System size: 11 kWp
System type: Grid-tied
Documented annual output: 15,930.3 kWh
Specific yield: 1,448 kWh/kWp/year
Performance ratio: 83.5%
Evidence period: DOE-documented annual operation
What the source does not prove
What this should change in your planning
- Mixed daytime household and office loads may improve self-consumption.
- Performance ratio is useful for checking overall system losses.
- Actual production should be compared with the installer forecast after commissioning.
How to compare this case with your own project
Start with capacity, system type, location, evidence period, and specific yield. This 11 kWp project documents 15,930.3 kWh of annual production, but that figure should not be copied directly into another property. Roof orientation, shade, weather, inverter limits, downtime, maintenance, and the share of electricity used during daylight can change both production and financial value. Compare the documented yield with the visible national planning range, then enter your own bill, roof, and backup requirements in the calculators.
Treat the project as evidence, not a promise of identical results.
