Charlesland Farm is a commercial piggery in Capas, Tarlac where electricity runs continuously. Ventilation, feeding systems, water pumps, and lighting operate across the facility throughout the day, creating a sustained and predictable load that makes solar a strong operational fit. With utility tariffs in Tarlac among the most punishing in Central Luzon, the monthly electricity bill had become one of the farm’s most significant recurring costs.

The 200.00 kWp system was sized against real operating loads rather than theoretical capacity. SMA Germany STP110-60 CORE2 inverter technology was selected for its reliability at this scale, with Sunova Solar bifacial modules and continuous SMA ennexOS monitoring completing the installation. System layout was designed with expansion in mind, when the decision is made to grow the facility or add capacity, the architecture is ready for it.

Annual generation of 295,000 kWh delivers PHP 3.24 million in savings per year against a 2.9-year payback. Lifetime savings are projected at PHP 83.6 million. The system targets daytime consumption directly, reducing grid draw during peak hours and limiting exposure to future tariff increases.

For agricultural operators evaluating the numbers honestly, the ultimate guide to commercial solar ROI in the Philippines sets out exactly how payback is calculated against real consumption patterns rather than optimistic assumptions.
