Nigeria - 440 kwp trapezoidal roof

Project Overview

This project overview outlines a 440 kWp solar PV installation designed for a trapezoidal metal roof in Nigeria. Given the scale and the specific environmental conditions in the region, this installation prioritizes structural integrity, long-term durability, and optimized energy yield.

The Challenge

• Roof Integrity and Load Bearing: Trapezoidal metal roofs require precise mounting. A common failure is installing mounting components in the "valley" (the low point) instead of the "crest" (the high point) of the roof rib. Valley mounting is prone to water pooling and leaks, which can lead to structural rot or corrosion.
• Waterproofing and Sealing: Every L-foot penetration represents a potential leak point. In Nigeria's rainy climate, improper sealing—such as failing to use high-quality EPDM gaskets or over-tightening screws—can lead to long-term water damage that compromises the entire building's interior.
• Wind Uplift: Solar arrays on trapezoidal roofs act as large "sails." If the L-foot anchors are not secured directly into the underlying structural purlins (rather than just the thin metal sheet), high-velocity wind gusts common in Nigeria can rip the panels and mounting rails from the roof.

Our Solution

To ensure your 440 kWp installation in Nigeria is resilient, efficient, and long-lasting, our solution centers on a high-grade L-Foot and Long Rail mounting system specifically engineered for trapezoidal metal roofs. By emphasizing structural precision and environmental protection, this approach mitigates the risks associated with Nigeria’s tropical climate.

We strictly adhere to crest-mounting (fixing to the high point of the roof rib) rather than valley-mounting.

The use of long aluminum rails provides a continuous, stable foundation that is superior to point-load systems.
