Envision-Monitoring on News

Globe Telecom, a major provider of telecommunications services in the Philippines, commissions Solenergy Systems Inc., a leader in Renewable Energy and Embedded Technologies, for a solar PV + battery storage system project for its tower in Pitabunan, Concepcion, Tarlac.

The tower’s solar PV system will lessen the carbon footprint of Globe’s base stations by reducing the runtime hours and the emissions of onsite gensets.

The system comprises quality components including DMEGC solar modules for high-conversion efficiency. The battery storage system is composed of Studer devices Xtender XTM4000-48, Variostring VS-120, Xcom-485i, Xcom-CAN, and RCC 2.0, as well as BYD Premium LVL 15.4 to optimize self-consumption with battery and solar backup.

To offset energy usage from gensets, and to gather data (e.g., electrical demand and fuel consumption) for analysis and reporting, an energy monitoring system—Envision—is also installed, comprising ENLITE, ENGAUGE 314, Industrial Cellular Router and Fuel Level Sensor devices.

This pilot project with Globe will be monitored regularly to assess its effectiveness in achieving its energy efficiency goals. Parameters such as solar performance ratio, fuel savings, and monitoring system up-time shall be observed throughout the duration of the PoC.

Annually, the solar PV system can generate 5000 kWh of energy, covering around 30% of the overall electricity demand of the tower. It is expected to have a cumulative yield of approximately 25000 kWh in 5 years. Over the same period, the solar power system is calculated to offset an estimated 20 tons of CO2.
