What are the Tax Incentives for Solar Power in Australia?

Both federal and Victorian state governments offer powerful financial incentives and tax deductions designed to make solar panel adoption financially irresistible for homeowners and commercial businesses alike.

1. Small-scale Technology Certificates (STCs)

Under the federal Renewable Energy Target (SRES), eligible systems up to 100kW qualify for Small-scale Technology Certificates (STCs). These certificates act as an immediate upfront discount on your solar invoice, reducing system purchase costs by thousands of dollars at the point of sale. At Billabong Solar, we apply this discount directly so you only pay the net balance.

2. Commercial Instant Asset Write-Off

For eligible small-to-medium Australian businesses, purchasing a commercial rooftop solar system or commercial battery storage unit can qualify for accelerated depreciation or instant asset write-off schemes under ATO guidelines. This allows businesses to deduct the cost of the asset immediately, significantly reducing company tax liabilities.

3. Large-Scale Generation Certificates (LGCs)

For systems exceeding 100kW (such as warehouse rooftops, logistics parks, manufacturing plants, and retail centres), businesses can participate in the Large-scale Renewable Energy Target (LRET). This generates ongoing tradeable certificates for each megawatt-hour (MWh) of renewable power produced, creating a continuous secondary income stream.
