Graymont Energy has completed and commissioned a 400-kilowatt solar photovoltaic system for a manufacturing facility in the Greater Accra Region, marking one of the largest single installations in the group's portfolio to date. The system, which includes a ground-mounted array and a battery storage component, entered commercial operation after a commissioning period that included load testing, performance verification, and integration with the facility's existing backup generator infrastructure.
The 400kW capacity was determined through a detailed energy audit and load profile analysis that Graymont Energy conducted over eight weeks prior to design finalisation. Manufacturing facilities present a more demanding solar sizing challenge than office or retail buildings because their load profiles are uneven, with significant variation between production and non-production hours, and because the cost of a power interruption to an active production line is disproportionately high. The system was sized and configured to cover the facility's core operational load during peak production hours with adequate buffer.
Following commissioning, the facility's real-time energy monitoring data shows solar generation covering approximately 62% of total electricity consumption across a standard operating week. The residual grid draw is concentrated in early morning periods before peak solar output, and the battery storage component provides coverage for brief cloud-induced generation dips that might otherwise cause voltage fluctuations in sensitive equipment. The client has reported no production interruptions attributable to power supply since the system entered operation.
The financial impact is already visible in the client's monthly electricity accounts. The facility was previously absorbing approximately GHS 85,000 per month in grid electricity and diesel costs combined. Post-commissioning data from the first billing cycle shows that figure reduced to under GHS 32,000, a reduction consistent with the pre-project modelling. At that run rate, the capital cost of the installation is on track for a payback period of under four years.
The project adds to a growing body of completed commercial solar installations in Graymont Energy's portfolio across the manufacturing, hospitality, and real estate sectors. Each project informs subsequent engineering decisions, and the group's accumulated dataset from active installations across Greater Accra and beyond provides a basis for increasingly precise energy modelling that benefits clients during the audit and design phase.
