Cold chain distribution never stops. Grupo Marilen has been supplying frozen products, dairy, meat, seafood, and fresh produce across Santiago City and the wider Isabela region since 1993, and the refrigeration, warehousing, and logistics infrastructure that keeps that supply chain moving draws substantial power around the clock.

Solar covers the daytime portion of that load, refrigeration, lighting, and administrative operations during peak warehouse activity hours. The system has been running on original SMA Germany STP25000TL inverters and SolarWorld Germany modules since September 2018, monitored continuously via SMA ennexOS. Capital was recovered by late 2023 and the system has been delivering pure savings since.

For a distribution business where product quality depends on uninterrupted cold storage and operational margins are tight across a large workforce, controlling the electricity overhead is not a sustainability exercise. It is a commercial necessity.

Nearly seven years of reliable performance on a demanding cold chain facility demonstrates what commercial solar energy systems deliver when the specification matches the actual operational profile of the site.
