Space-Optimized Elevated Solar Racking Structure | Manila Case Study

Elevated Rooftop Solar Platform Project | Manila, Philippines

This project demonstrates how Top Fence Solar successfully solved severe rooftop space constraints and infrastructure interference challenges for a commercial building in Manila, Philippines.

Location

Manila, Philippines

Structure Material

Hot-Dip Galvanized Steel / Al-Mg-Zn Coated Steel

Solution Type

Elevated Rooftop Solar Platform

Target Issue

Rooftop Infrastructure Obstacles & Limited Installation Space

Project Introduction

The target rooftop was heavily occupied by cooling towers, water tanks, cable routing systems, and maintenance walkways, leaving insufficient usable area for a conventional photovoltaic array. To maximize rooftop utilization without disrupting building operations, Top Fence Solar engineered a premium elevated solar racking structure capable of spanning across existing rooftop facilities.

The elevated platform design created a secondary solar installation layer above the rooftop infrastructure, significantly increasing solar deployment capacity while preserving maintenance accessibility and HVAC operational efficiency.

Engineering Highlights

Overhead Clearance Design

The solar platform was elevated to an optimized structural height, allowing uninterrupted airflow around HVAC cooling systems while maintaining clear service access beneath the solar array. This elevated configuration minimized shading impact and ensured long-term rooftop operability.

Structural Integrity & Wind Safety

Due to the elevated exposure profile, the structure was reinforced using heavy-duty steel bracing, optimized load distribution, and aerodynamic tilt angle calculations designed to resist high wind pressure conditions commonly experienced in the Philippines during tropical storms and typhoon seasons.

Advanced Corrosion Resistance

The entire support system utilizes hot-dip galvanized steel and Al-Mg-Zn coated structural components engineered for tropical coastal climates. The anti-corrosion treatment enhances durability against humidity, salt-laden air, and long-term environmental exposure, supporting a projected service life exceeding 25 years.
