A 21.6kWp PV system comprising of 108 numbers of 200Wp panels, 24 numbers of 1000Ah VRLA batteries, 3 numbers of SMA 8.0H Sunny Island and 1 number of SMA STP25000-TL. The system was initially installed in 2015 but then due to the poor operation and maintenance the system stopped functioning all together after 2018. The system was then kept in a redundant state for a period of almost 5 years. In mid 2023, the system was renovated with the replacement of the batteries. The solar modules were mounted atop the new roof of the old hospital building.
