Hotels live and die by their operating cost structure. Air conditioning runs around the clock, lighting covers guest rooms, corridors, dining areas, and function spaces, and the expectation of a comfortable environment never switches off. For El Cabalen in Tarlac City, this was not a new problem. Solaren had already installed a first system on the property, and the results were clear enough that the decision to expand was straightforward.

Phase II added 46.89 kWp to the existing installation, bringing the hotel’s total solar capacity to a level that makes a genuine dent in its grid dependence. Eight SMA Sunnyboy inverters manage the array, paired with Sunova Solar bifacial panels and monitored through SMA ennexOS and Sunny Portal. Annual generation from the Phase II system alone runs to around 69,000 kWh, displacing grid power during the peak daytime hours when hotel facilities are at their busiest and grid tariffs are at their highest.

The phased approach worked well here. The first installation proved the financial case on this specific property, with its actual load profile and actual TARELCO billing rates. Phase II was an expansion of something already working, not a leap of faith.

For a hospitality business with constant daytime loads and no ability to pass rising electricity costs on to guests, that kind of certainty matters.
