Sierra Leone - 270 kwp steel solar carport

Project Overview

This 270 kWp Steel Solar Carport Project in Sierra Leone is a landmark infrastructure initiative. By converting expansive, sun-exposed parking areas into a high-capacity power generation plant, the project provides a dual-purpose solution: critical vehicle protection and a reliable, decentralized source of renewable energy for local facilities.

The Challenge

• Managing Tropical Precipitation and Humidity: Unlike projects in arid climates, the structure must handle massive, sudden water volumes. Any poor drainage design leads to water ponding on the canopy, which adds significant weight and can trigger premature rust at connection points due to constant moisture exposure. The "leaking" of water onto vehicles below must also be prevented to maintain the facility’s utility.
• Corrosion in a Coastal-Humid Climate: Protecting the steel structure from corrosion throughout its 25-year lifespan. Standard paint finishes will fail quickly; the challenge is to ensure that the protective zinc coating is uniform and that every bolt, nut, and weld—if any—is shielded against "rust-creep."
• Foundation Stability in Tropical Soils: Designing a foundation system that provides enough bearing capacity to hold a 270 kWp array—which experiences massive wind uplift forces—without requiring excessively deep or complex concrete excavations that could disrupt the facility’s existing parking operations.

Our Solution

To address the structural and environmental challenges of the 270 kWp Nigerian carport project, we provide a professional-grade Single-Pillar Carbon Steel Solar Carport Solution. This system is specifically engineered to handle high wind loads while maintaining the architectural elegance of a cantilever design.

Our design utilizes high-strength carbon steel as the primary structural material, treated with advanced finishing processes to ensure durability in local diverse climate.
