When Weatherfast Ltd looked to future-proof their operations and tackle rising energy overheads, they turned to us for a high-performance renewable solution. By utilising their expansive factory roof space, we transformed an underused asset into a powerhouse of clean energy, significantly reducing their reliance on the grid.

The Hardware: Precision and Efficiency

To ensure maximum yield and long-term durability, we selected industry-leading components tailored for industrial demand:

Trina Vertex S+ 450W Modules:

These dual-glass, N-type modules were chosen for their exceptional efficiency and fire safety ratings. With bifacial technology, they ensure Weatherfast captures every possible watt of solar irradiance.

Three Solis 40kW 3-Phase Inverters:

To handle the significant load, we installed a trio of Solis dual-MPPT inverters. These units provide robust power conversion and intelligent monitoring, allowing the client to track their energy production in real-time.

Impact: Slashing Costs and Carbon

The primary driver for this installation was commercial viability. By generating their own electricity on-site, Weatherfast Ltd has effectively locked in a significantly lower energy rate for the next 25+ years.

Key Benefits Include:

Generating over 110,000kWh in year 1

Immediate Cost Reduction:

A drastic drop in monthly utility bills, allowing capital to be reinvested into their core manufacturing business.

Protection Against Volatility:

Insulation from the unpredictable price hikes of the wholesale energy market.

Improved Corporate Social Responsibility:

A substantial reduction in the factory’s carbon footprint, aligning the brand with modern sustainability standards.
