KITRAC was commissioned by Kwale County government to design and install an off-grid solar power system for a secondary school in a rural area with no access to the national grid. The school relied on expensive dry-cell batteries for lighting and had no power for its computer lab, science equipment, or security lights — severely limiting learning opportunities for over 600 students.
The KITRAC team designed a 15 kW off-grid solar system with 48V lithium battery storage sized to carry the school load through the night and across two overcast days. The installation included 37 × 400 Wp panels on a purpose-built ground-mount structure, a 15 kW hybrid inverter-charger, a 48V / 400 Ah battery bank, and complete rewiring of the school's four classroom blocks, staff room, library, and computer lab — a total of 18 circuits.
On completion, the school gained reliable 24-hour electricity for the first time. The computer lab became fully operational with 25 workstations, science practical sessions could be conducted after dark, and the perimeter lighting dramatically improved campus security. KITRAC also delivered a handover training session for the school's maintenance staff.
37 × 400 Wp solar panels on a galvanised ground-mount structure positioned to clear the school's boundary trees, maximising generation across both wet and dry seasons.
15 kW hybrid inverter-charger with 48V Lithium-Ion battery bank providing 2-day autonomy — the school maintains power through weekends and public holidays without generator backup.
Full rewiring of 6 buildings covering 18 circuits, including a dedicated 25-workstation computer lab circuit, science lab equipment sockets, and LED lighting throughout.
Perimeter security lighting on a dusk-to-dawn sensor circuit, providing campus-wide illumination and eliminating after-dark security incidents reported by the school administration.
Staff handover training delivered on completion; system has operated without fault since commissioning and KITRAC conducts a bi-annual inspection under the County maintenance programme.
