Missionary Benedictine Sisters, Karen

The rising electricity costs, fuel costs arising from generator backup, frequent outages, and maintenance costs were some of the major challenges the institution faced.

Knights Energy proposed several measures to reduce the energy consumption rates and came up with a lean combined (total) energy footprint that was powered by the proposed Photovoltaic.

The 100 kWp solar array and 514kWh (10,700AH) battery bank with the SMA Multicluster System with Sunny Island runs the entire center during the day and night.
