The K25,000 project was completed by BSP staff with the assistance of a local contractor who installed five solar panels that will supply 800kW of electricity to the school.
At the project handover last week, head teacher Cherobin Tibokre thanked BSP for the initiative. "This project will benefit more than 300 students who attend this school," he said.
BSP says it plans to deliver 48 community projects in 2018, worth more than K1.2 million. Mendi and Kundiawa schools were the other two schools at which solar lighting was installed.
