Since December 2020, the Congregation of Sisters of Mary from the Philippines have inaugurated a 10 000 m2special charity boarding school for 600 girls from poor and less privileged families in Kisarawe in the Archdiocese of Dar es Salaam, Tanzania and 29 teachers. The School offers free secondary education to poor girls from Form 1 to Form 6, with free vocational training and help to seek jobs. Their own green electricity generative system was installed by AG Energies through a 50 KW peak hour on-grid solar system. The system includes 152 PV panels of 325 Watts set on an aluminum roof top frame, a 3 phases 50 KW inverter as well as a Current transformer on each phase to complete the system. Protection against lightning was added through a surge protector. E-distance monitoring was installed through a smart Meter that allows AG Energies to monitor 24/24 the system from Dar es Salaam. Electricity is produced enough for the whole school: All the class rooms, dormitories, kitchen, CCTV Camera system, Water pumps, swimming pool, printing devices, computers, charging plugs.
