J Mart is one of Tarlac City’s most established retail landmarks, running continuous lighting, air conditioning, refrigeration, and point-of-sale systems across a large commercial floor space. Daytime electricity consumption at this scale adds up quickly, and the monthly utility bill had become one of the most significant recurring costs in the operation.

The installation was divided across two meters, each served by its own SMA Germany STP50-40 CORE1 inverter, a configuration that required careful load analysis and system design to ensure balanced generation and clean metering compliance across both connection points. Sunova Solar bifacial modules were selected for their consistent output under the direct sun conditions typical of Tarlac’s commercial rooftops.

At 100.04 kWp the system generates 147,559 kWh annually, delivering PHP 1.62 million in savings per year against a 3.2-year payback. Lifetime savings are projected at PHP 41.8 million. The installation offsets the large majority of J Mart’s daytime consumption, reducing grid draw during peak hours when utility rates are at their highest.

For retail operators with significant daytime loads across multiple meters, commercial solar installation structured around the actual metering configuration from the outset avoids the compliance issues that arise when system design and utility requirements are not aligned.
