CK Hog Farm
- Hog Grow-out Farm with Off-Grid Option
- System Size: 50.22 kWp
- Completion: 17-Aug-2018
- Tanay, Rizal, Philippines
Project Summary
Most farm solar installations connect to a single energy source: the grid. CK Hog Farm in Tanay, Rizal presented a more complex brief. An existing biogas system was already generating power from farm waste around the clock. The question was how to integrate solar generation into that existing renewable setup without creating instability, safety issues, or wasted output from either source.
The electrical design required careful synchronisation of two independent generation streams: solar producing clean daytime power, biogas running as continuous baseload. Getting both sources to work together without conflict demanded the kind of close engineering attention that a standard installation contractor would not be equipped to handle.
Solaren delivered a dual-source system that has been running reliably since August 2018. Nearly seven years of operation on a demanding hog grow-out farm, with both renewable sources contributing to a grid exposure that has dropped significantly since commissioning.
For agricultural operations already investing in renewable generation, adding solar into an existing energy mix is not always straightforward. Industrial solar power systems designed around the full electrical picture of a working farm deliver outcomes that a rooftop-only approach cannot.
