Calayaan Poultry Farm
- Commercial Broiler House Solar Installation
- System Size: 43.32 kWp
- Completion: 21-Jun-2024
- Sta Ignacia, Tarlac, Philippines
Project Summary
Broiler houses in Tarlac run hardest in summer. Fans and evaporative cooling pads operate continuously to protect flock health during the hottest months, and electricity bills peak at exactly the same time. For Calayaan Poultry Farm in Sta. Ignacia, that seasonal cost spike was the primary driver for solar.
The grid-tied system was sized to cover the farm’s full daytime peak without curtailment, with long roof runs mapped for even irradiance across all strings. Power factor support was built into the inverter specification, keeping the local line stable under the variable loads that poultry ventilation systems produce. Net metering captures credits during lower consumption periods, adding value across the full annual cycle.
The result is predictable energy costs across grow-out cycles and harvest periods — exactly the kind of operational stability that makes farm planning more manageable.
SMA Germany STP110 CORE2 inverter technology paired with Sunova Solar bifacial modules has delivered consistent performance since June 2024, monitored via SMA ennexOS.
For broiler operations where summer ventilation loads drive the highest costs, industrial solar power systems sized correctly around the peak demand profile deliver the most meaningful savings precisely when margins are under the most pressure.
