About This Course
The Solar Panel Installation course trains students to design, install, and commission off-grid and grid-tied solar power systems — one of the fastest-growing sectors in Nepal as households and businesses seek reliable power.
With Nepal's electricity supply improving but still unreliable in many areas, solar technicians are in high demand across rural and urban regions. This is an excellent 2-month course to complement an electrical wiring qualification.
