Romarosa
- Poultry Farm with Tunnel Ventilation
- System Size: 99.62 kWp
- Completion: 1-Jun-2023
- Tanay, Rizal, Philippines
Project Summary
Romarosa’s current 99.62 kWp solar installation in Tanay, Rizal reflects a major expansion of an earlier Solaren system installed several years before the 2023 phase. The later work approximately doubled the site’s solar capacity after the original installation had already established a strong operating record.
The system is fully net-metered, although most daytime generation is consumed directly by the farm’s ventilation and cooling loads. The arrays are installed across two existing poultry houses. Part of the installation is particularly unusual, with modules positioned above a water-covered area, allowing the client to make productive use of space that would otherwise contribute little to the site’s energy needs.
Poultry farms are a demanding environment for electrical equipment because ammonia and moisture can accelerate corrosion. Solaren therefore specified modules certified for ammonia resistance and supports the installation with regular maintenance. Power-factor support was also configured through the inverter system. Performance has been exceptional since the original installation and subsequent expansion, with the installed SMA and SolarWorld equipment continuing to operate normally.
