Solar for Every Sector of the Kenyan Economy
Manufacturing and industrial
Daytime production loads are the ideal match for solar. We design for high self-consumption, power-factor correction and phased expansion across factory roofs and ground-mounts.
Hospitality
Hotels, lodges and camps run 24 hours. Hybrid systems with lithium storage cut diesel generator hours and deliver the quiet, clean power guests expect.
Education
Schools, colleges and universities reduce recurring costs and gain reliable power for labs, ICT and boarding facilities. We work to term-break installation windows.
Healthcare
Hospitals and clinics cannot lose power. We design redundant backup for theatres, cold chain, laboratories and ICU loads, with seamless transfer.
Agriculture and cold chain
Solar water pumping, irrigation, cold storage and processing lines, sized for rural grid conditions and remote monitoring.
Commercial real estate
Office parks, malls and warehouses lower service charges and improve tenant retention with on-site generation and backup.
NGOs and development partners
Field offices, health posts and community facilities delivered to donor reporting and procurement standards.
County and national government
Public buildings, water schemes, street lighting and institutional facilities delivered through competitive tender with full compliance documentation.
