EOFY 2026 Solar Deals: End of Financial Year Offers Before 30 June

Two government-backed incentives make June 2026 one of the strongest buying windows for solar in recent years. The federal $20,000 instant asset write-off for small businesses expires on 30 June 2026, and the NSW Home Energy Saver program is now offering zero-interest loans of up to $15,000 for residential solar and battery installations.

These 2 incentives sit on top of the ongoing federal STC rebate, which reduces the upfront cost of every qualifying solar installation based on system size and location. Together, they create a window where both businesses and homeowners can reduce the cost of going solar by thousands of dollars before the financial year closes.

Solar Galaxy is accepting EOFY bookings for installations across Sydney, Newcastle, Wollongong and regional NSW. Request a quote to confirm pricing and availability before 30 June.

Businesses with an aggregated turnover under $10 million can immediately deduct the full cost of eligible assets up to $20,000 each under the instant asset write-off. Solar panels, battery storage systems and inverters each qualify as separate assets, which means a business can claim multiple deductions in the same financial year.

The $20,000 threshold applies per asset, not per business. A 10kW commercial solar system, a 10kWh battery and a hybrid inverter can each be claimed separately if each individual asset costs less than $20,000. The asset must be installed and ready for use by 30 June 2026 to qualify for this financial year.

After 30 June 2026, the threshold reverts to $1,000, which removes the ability to claim most solar equipment as an immediate deduction. For a full breakdown of how the write-off applies to solar installations, see instant asset write-off for solar.

Three factors converge at the end of financial year that make June the strongest buying window for solar. First, the instant asset write-off deadline creates urgency for business purchases, and manufacturers respond with stock clearance pricing to move inventory before 30 June. Second, the federal STC rebate decreases each calendar year as the deeming period under the Small-scale Renewable Energy Scheme shortens, so locking in a system now secures a higher rebate value than waiting until next financial year.

Third, installer capacity is typically at its highest during Q2 (April to June) before the seasonal slowdown in July and August. This means shorter wait times between signing and installation, which matters when the asset needs to be installed and ready for use by 30 June to qualify for the write-off.

For residential buyers in NSW, the Home Energy Saver loan removes the upfront cost barrier entirely. Combined with the STC rebate applied at point of sale, a 6.6kW solar system can be installed with zero upfront payment and repayments starting from around $50 to $70 per month.

Solar Galaxy is booking EOFY installations across NSW for both residential and commercial systems. The process starts with a free site assessment where we confirm your roof layout, energy usage, and which incentives apply to your situation. We then provide a fixed-price quote that includes all equipment, installation, and the STC rebate applied at point of sale.

For business owners claiming the instant asset write-off, we prioritise scheduling to ensure the system is installed and operational before 30 June. For NSW homeowners using the Home Energy Saver loan, we guide you through the application with either Brighte or Plenti and begin installation once the loan is approved.
