Project Overview

Client: Ettason
Project Size: 100kW DC Solar
Project Type: Rooftop Commercial Solar System
Location: Western Australia

Westsun Energy was engaged to design and install a 100kW DC commercial solar system for Ettason.

The objective was to significantly reduce electricity costs, improve energy efficiency, and deliver strong financial returns through renewable energy integration.

As a WA-based commercial solar EPC provider, Westsun Energy delivered a tailored solution designed to support consistent daytime energy demand while ensuring reliable long-term performance.
