Project Overview
In April 2025, SUNPAL ESS was awarded the EPC contract for a commercial solar-plus-storage system at a newly established water plant in Nigeria. The facility required reliable, uninterrupted power to support critical operations amid unstable grid supply and high diesel costs.
The customized containerized solution, delivering 200 kW power output and 500 kWh of battery storage, was engineered, assembled, and factory-tested in approximately 25 days. The system was shipped and arrived on site in early July 2025 for final installation and commissioning, providing a rapid-deployment, plug-and-play energy solution tailored to the plant's needs.
