Liwayway Marketing Corporation — the company behind the Oishi snack brand — has expanded rooftop solar plant by plant with EPC partner Solaren Power since 2021: Phases 1 and 3 at Imus (235.2 kWp and 1.464 MWp, 2021), Phase 2 (381.5 kWp, 2022), the Pavia, Iloilo hub (410.4 kWp, 2023), the Pasay head office (60 kWp, 2024), the Liloan, Cebu plant (719.8 kWp, 2025) and Phase 4A at Imus (1.532 MWp, 2026). Together: about 4.8 MWp across seven systems, every one on Solaracks mounting.

A repeat client is the strongest evidence a component supplier can publish. Seven separate purchase decisions across five years — and across three island groups — mean the mounting earned its place on each successive roof after the earlier ones had been through commissioning and service.

Standardising one mounting system across a plant network also has an operational logic: the maintenance team meets the same clamps, rails and torque specs in Cavite, Cebu and Iloilo, and each new phase starts from engineering work the earlier phases already proved.
