The Bureau of Internal Revenue office in Tarlac serves the public every weekday with systems that depend on stable power. Lighting, computers, cooling, and client-facing services all run during daylight hours when demand and costs are highest. Solaren installed a rooftop solar system sized to support this exact pattern. The system now generates clean power that offsets a large portion of daily grid use, helping reduce utility costs while supporting more efficient operations. For the agency, this upgrade delivers long-term savings without disrupting services. For the public, it shows that government offices can lead by example in managing energy more responsibly.
