Residential Apartment, Owerri-Imo
20kVA solar installation for a multi-unit residential apartment building.
The Challenge
A 12-unit apartment building in Owerri suffered from near-daily grid failures. The landlord operated a 25kVA diesel generator to power common areas, water pumps, and security systems. Tenants were constantly complaining about noise and the additional service charge for diesel.
The generator required major repairs twice a year, and the landlord was considering selling the building due to the operational burden.
Our Solution
We installed a 20kVA hybrid solar system with 80kWh battery storage. The system powers all common area lighting, water pumping, gate automation, and security cameras.
Individual units remain on prepaid meters for their own consumption, while common area costs dropped to near zero. The rooftop panel installation preserves the building's aesthetic while maximising generation.
