Ice production runs around the clock and draws some of the heaviest refrigeration loads in any industrial category. The Angeles Ice Plant in Pampanga operates at that level continuously, with a 124.44 kW peak daytime demand across compressors, refrigeration systems, and processing equipment running on a multi-voltage electrical infrastructure that added a layer of complexity most solar contractors would not have been equipped to handle.

The roof made it harder still. Irregular sections, structural constraints, and layout geometry that resisted clean string planning meant the system could not be designed on paper and installed as drawn. Solaren’s solution was to deploy three SMA Germany STP50 inverters, each with multiple MPPT inputs, allowing individual strings to be tuned independently across the different roof sections and voltage conditions. Every part of the available roof was made to contribute, and every string was optimised against its actual orientation and shading conditions rather than averaged across the array.

Commissioned in June 2019 and still reliably performing over six years later, the 146.40 kWp system generates over 215,000 kWh annually, delivering more than ₱2.3 million in yearly savings against a load that never stops.

For industrial facilities with complex roofs, multi-voltage systems, and relentless operational demand, industrial solar power systems in the Philippines require engineering capability, not just installation capacity.
