Romarosa
- Poultry Farm with Tunnel Ventilation
- System Size: 99.62 kWp
- Completion: 1-Jun-2023
- Tanay, Rizal, Philippines
Project Summary
Romarosa’s expansion to 99.62 kWp was built on an earlier Solaren installation, with most daytime generation serving ventilation and cooling across two poultry houses. The project reflects the practical demands of solar for poultry farms, including changing production loads and exposure to ammonia and moisture. Solaren specified ammonia-resistant modules and continues to support the site through regular solar maintenance and equipment inspections. The expansion also made use of an unusual mounting area above water, adding generation within the farm’s existing layout.
The Tanay, Rizal project expanded an earlier installation during the 2023 phase, approximately doubling the farm’s solar capacity. The system is fully net metered, with power-factor support configured through the inverter system. The installed SMA and SolarWorld equipment continues to operate normally.
