Philippine, 20kWp Off-Grid
Energy Storage System

In the mountainous and hilltop area of Kulambogan, Sibagat ADS, the Philippines, frequent power interruptions from the grid is common and normal to the residents there. To provide a more reliable study environment for the children, this school commissioned JMJ SOLAR to install two solar systems on top of this two-unit school building with two Growatt off-grid inverters, which is of 20kW power output in total. With the sustainable and stable power supply from the solar system, the school can then provide better conditions for the teachers and students.
