Solar Panels in Hornsby, New South Wales — Compare Local Installers & Rebates

Yes. Hornsby residents are eligible for the federal Small-scale Technology Certificate (STC) rebate, which significantly reduces the upfront cost of a solar system. The value depends on system size and installation date.

Most Hornsby homes suit a 6.6kW to 10kW system depending on energy usage and available roof space. Properties shaded by large trees unique to the Hornsby Shire often benefit from microinverters or optimisers.

Ausgrid typically applies a standard 5kW export limit per phase for residential connections. If you have a single-phase connection, this restricts the amount of power you can feed back into the grid to 5kW at any one time, meaning a 5kW inverter is usually recommended unless you have high daytime consumption.

Battery storage is becoming more attractive as feed-in tariffs decrease across New South Wales. A battery lets you store excess solar energy for use at night, reducing reliance on the grid. Payback periods are typically 8–12 years in the Sydney region, improving annually.

A standard residential solar installation in Hornsby takes 1–2 days. After installation, your installer will lodge grid connection paperwork with Ausgrid, which typically takes 2-4 weeks before your system is fully approved to export.

NSW residents can access the federal STC rebate, reducing system costs by thousands of dollars. Feed-in tariffs are paid by energy retailers and vary — it's highly recommended to compare offers from multiple retailers to maximise your savings.
