BIR Tarlac
- Government Office Installation
- System Size: 30.78 kWp
- Completion: 9-Jan-2019
Project Summary
The Bureau of Internal Revenue office in Tarlac serves the public daily, relying on stable electricity to support lighting, cooling systems, computer networks, and client-facing services. Peak demand occurs during daylight hours, when both activity levels and utility tariffs are highest.
The primary challenge at this location was the limited usable roof space. To achieve meaningful savings within spatial constraints, Solaren specified high-efficiency solar modules to maximize output per square meter. System sizing was carefully aligned with the office’s daytime consumption pattern, and full net metering clearance was secured from the local utility to ensure surplus generation translated into measurable financial returns.
The strategic value of this approach reflects the thinking outlined in How a Renewable Energy Company Philippines Can Transform Your Energy Future, where disciplined design and long-term service planning determine real outcomes.
Years after installation, the system continues to operate reliably under Solaren’s ongoing support. It delivers sustained savings without interrupting public service, demonstrating that government institutions can adopt renewable energy responsibly while maintaining operational continuity.
