100kW Solar System Packages Rockhampton & Gladstone

A 100kW solar system is the most common large-scale commercial solar system. The reason is the the STC (Small-scale Technology Certificate) threshold is set at 99.9kW. Most commercial systems are designed just under this limit, at 99.9kW, so businesses can fully benefit from the STC rebate, significantly lowering the initial installation costs and increasing return on investment.

If your property needs more than 100kW of solar power, a common strategy is to install the first 99.9kW to secure the rebate, then add a second system to cover your additional energy requirements. This approach maximises financial returns while ensuring your business gets the power it needs.

For systems of this size, Ergon Energy requires an extensive application process for anything over 30kVA, including the installation of a grid protection relay board to comply with grid safety standards. The team at REEF SOLAR & ELECTRICAL will guide you through this process, ensuring a smooth and efficient installation.
