Project Overview
This commercial solar solution for a vocational school in Benin combines a 46.8kWp rooftop PV design with a 50kW hybrid inverter and approximately 100kWh of lithium battery storage. The complete configuration supports daytime solar use and backup planning for selected teaching and administrative services.
Project Background
Three rooftop array groups allow solar generation to be placed close to classroom demand while accommodating existing roof structures. The installation layout needs to preserve inspection routes, drainage and access to serviceable equipment.
The school’s load schedule prioritizes computer classrooms, essential lighting, communications, administration and security. Workshop machinery requires separate assessment of running demand and starting current before being connected to backup power.
Project Challenges
System design must coordinate available roof area, shading, PV string limits and cable routes. Structural loading, wind resistance and waterproofing also need to be assessed before mounting work begins.
Electrical planning must balance daytime consumption, battery charging and essential-load reserve. The backup circuit should remain within inverter capacity and available battery energy during a utility interruption.
WHC Power Solution
WHC Power’s configuration integrates rooftop PV, lithium battery storage, hybrid inverter control and electrical protection. Available solar energy can supply school loads during the day and charge the battery when surplus generation is available.
BMS communication and energy management settings coordinate battery protection, reserve levels and discharge priorities. A separate essential-load distribution arrangement limits backup demand to the equipment identified in the school’s load assessment.
System Integration and EPC Support
WHC Power supports EPC partners with PV string planning, battery and inverter compatibility, protection coordination and technical configuration. Installation planning covers mounting, earthing, isolation, surge protection and access for maintenance.
Commissioning should verify communications, operating priorities, protection settings and backup operation. Backup duration depends on actual load, usable battery energy and reserve settings. Sensitive equipment requiring uninterrupted supply should retain a suitable UPS where needed; any generator connection requires its own compatibility assessment.
System Configuration
Solar PV Design Capacity: 46.8kWp rooftop PV
Hybrid Inverter Rating: 50kW
Battery Configuration: Approximately 100kWh lithium battery storage
Control: BMS communication and energy management
Application: Selected computer classrooms, lighting, networks, administration and security
Operating Arrangement: Rooftop solar self-consumption with essential-load backup
Project Benefits
The design aims to increase daytime solar use and make stored energy available for essential school activity. At sites with backup generation, coordinated storage can reduce unnecessary generator runtime.
Using the roof preserves ground-level space for teaching and daily access. Complete system planning helps the project team address installation, compatibility and maintenance requirements before implementation.
