Solar rebate update: STC deeming period reduces from 2026

The federal Small-scale Technology Certificate (STC) scheme is winding down toward its 2030 end date. Each year, the deeming period shortens by one year, reducing the upfront rebate on new solar installations. From 2026, the deeming period drops to 4 years (down from 5 years in 2025), meaning fewer STCs per kilowatt installed and a smaller upfront rebate. Perth homeowners who install in 2025 or lock in quotes before the 2026 reduction apply get the higher current rebate value. STCs trade at the current market rate, so call us for up-to-date figures. See the Clean Energy Regulator's STC page for full scheme details.

What Electrical Safety and Compliance Requirements Apply to Solar Installations in Perth?

Solar installations in Perth must comply with strict electrical and safety standards, including AS/NZS 3000 (Australian Wiring Rules) and Energy Safety WA requirements.

Common questions

Frequently Asked Questions About Solar Installation in Perth

Do you need council approval for solar panel installation in Perth, WA?

In most cases you do not need council approval for standard rooftop solar in Perth. However, heritage-listed properties, strata-titled properties, or systems exceeding standard export limits may have additional requirements. We handle all Western Power network operator approvals and Synergy retailer notifications on your behalf.

How long does solar installation take in Perth?

A standard residential solar installation in Perth typically takes one to two days from start to commissioning, depending on system size and roof complexity. After installation, Western Power connection approval is required before your system can export to the grid. This process typically takes 5–15 business days. We manage this process on your behalf.

What is the Western Power 5kW inverter export limit for Perth homes?

Western Power limits single-phase residential connections in Perth to a maximum 5kW inverter export capacity. You may install a larger solar array (e.g., 6.6kW of panels) with a 5kW inverter, as panels rarely produce their rated output simultaneously. Systems exceeding this export limit require separate Western Power approval and potentially a network upgrade.

Should I choose a string inverter or microinverters for my Perth home?

For Perth homes with a simple, unshaded north or west-facing roof, a quality string inverter is typically the most cost-effective option. Microinverters or optimisers are worth considering if your roof has shading from trees, chimneys, or neighbouring structures, as they allow each panel to perform independently. Our team assesses your specific roof and recommends the right inverter type for your property.

Are your solar installers expert and accredited in Perth?

Yes. All Ares Energy solar installations are carried out by expert Western Australian electricians. Our business holds SAA (Solar Accreditation Australia) accreditation and is a NETCC Approved Solar Retailer. Installer accreditation is required to access STCs, the government incentive that reduces your upfront installation cost.

What feed-in tariff will I receive after installing solar in Perth?

Perth homeowners on the Synergy network are enrolled in Synergy's Distributed Energy Buyback Scheme, which pays 10c/kWh for solar exported during peak hours (10am–3pm, 7 days a week) and 2.5c/kWh at all other times (Synergy's current rate for new connections post-July 2020; always verify current rates with Synergy). Maximising self-consumption during the day and exporting during the evening peak can significantly improve your financial return.

How much has the solar rebate reduced in 2026?

The federal STC (Small-scale Technology Certificate) rebate reduces each year as the deeming period shortens on the path to the scheme ending in 2030. In 2026, new solar installations generate fewer STCs than in 2025, which means a smaller upfront discount. The exact reduction depends on your system size and postcode zone. For current rebate estimates, call Ares Energy on 1300 717 583.

Is the solar rebate still available in Perth in 2025/2026?

Yes, the federal STC rebate is still active and available to Perth homeowners in 2025 and 2026. However, the value reduces each year. A typical 6.6kW system in Perth still qualifies for a significant rebate. Contact us for a current quote including all applicable incentives.
