Commercial Solar Projects by Westsun Energy
Westsun Energy has delivered a wide range of solar projects across Western Australia for offices, retail spaces and commercial clients. Each installation highlights how solar can reduce operating costs, improve energy reliability and enhance the sustainability credentials of a business while also supporting long-term growth and resilience.
Featured Project – Rooftop Solar Installation on the Crime and Corruption Building and ATO Offices
Westsun Energy was engaged by the Government of Western Australia to design and deliver a 200kW rooftop solar system across two landmark Perth CBD sites — the Crime and Corruption Building and the Australian Taxation Office.
High-rise solar installations present unique challenges, from limited roof access and shading caused by surrounding towers to the logistics of lifting equipment in a busy city centre. Westsun Energy managed each stage with precision, coordinating crane operations, traffic management, and complex cable runs to ensure the project was completed safely and on schedule.
The system was built using SolarEdge inverters and optimisers, chosen to maximise output even in shaded conditions. With this technology, both buildings now benefit from reliable energy generation throughout the day, despite the constraints of the CBD environment.
The new installation significantly reduces electricity costs for the sites while strengthening their sustainability performance and energy resilience. This project highlights Westsun Energy’s ability to deliver safe, future-focused solar solutions for complex, high-rise commercial environments.
Frequently Asked Questions
Thinking about solar for businesses or offices? We’ve answered some of the most common questions to help you understand how solar energy can reduce costs, improve efficiency and support long-term sustainability.
What are the benefits of solar for businesses?
Solar for businesses helps reduce operating costs by lowering electricity bills, stabilises energy supply, and demonstrates a commitment to sustainability. Installing a solar system also improves energy independence and can boost your company’s reputation with customers who value green practices. Over time, solar offers a strong return on investment through consistent savings and reduced reliance on grid power.
Is solar for offices worth the investment?
Yes, solar for offices is a cost-effective solution that delivers both financial and environmental returns. Office buildings typically have high daytime energy use from lighting, computers, and HVAC systems, which aligns perfectly with solar generation. By switching to solar, offices can cut overheads, improve energy resilience, and achieve sustainability goals without disrupting day-to-day operations.
How do solar energy solutions work for commercial buildings?
Solar energy solutions for businesses and offices involve installing rooftop panels that convert sunlight into electricity, often supported by battery storage for peak demand. The system is designed to match the energy profile of the building, ensuring maximum efficiency. Businesses benefit from reduced grid reliance, predictable energy costs, and long-term savings while supporting cleaner, renewable energy use.
Can small businesses and large office buildings both use solar?
Absolutely. Solar for businesses is scalable, which means systems can be tailored to suit anything from a small retail shop to a multi-storey office building. Smaller systems provide affordable entry points for businesses wanting to cut costs, while larger installations for office complexes can deliver substantial savings and improved sustainability performance across the organisation.
