Lower Upfront Costs With Government Incentives

Switching to solar is even more affordable thanks to generous federal and state incentives designed to reward homeowners and businesses for going green. The right combination of rebates and Small-scale Technology Certificates (STCs) can significantly cut the upfront cost of a quality solar installation, sometimes by several thousand dollars.

Understanding precisely what you’re eligible for can be confusing, which is why we keep up to date with the latest government programs, STC values, and rebate criteria. Our team will guide you through the process so you maximise every available incentive and keep your out-of-pocket costs as low as possible.

Whether you’re installing a new system or upgrading an existing one, we’ll help you take full advantage of the current rebates.
