Connecting solar and batteries in Wollongong

Wollongong is on Endeavour Energy's network, which covers Greater Western Sydney, the Blue Mountains, the Southern Highlands, and the Illawarra and South Coast.

Step 1: Application first
Installers apply to connect solar and batteries through Endeavour Energy's online portal. Your installer usually handles this.
Step 2: Flexible exports
Endeavour Energy's flexible exports allow up to 10 kW per phase most of the time. From November 2026 they become the default for eligible new and upgraded solar, with a fixed 1.5 kW export cap as the alternative.
Step 3: Emergency backstop from November 2026
NSW is phasing in an emergency backstop by postcode between November 2026 and February 2027. Endeavour Energy's website has a postcode checker. New and upgraded solar systems will need a compatible inverter and a test at installation. Existing systems and like-for-like warranty replacements are exempt.

Incentives for homes in Wollongong

These are the incentives open to homes in the area. Your installer normally applies the federal discounts to the quoted price.

Solar: small-scale technology certificates (STCs) reduce the price of eligible systems. Wollongong postcodes are in the Clean Energy Regulator's zone 3, which sets how many certificates a system earns.
Batteries: the federal Cheaper Home Batteries Program discounts eligible batteries through the same certificate scheme.
NSW virtual power plant incentive: the Peak Demand Reduction Scheme pays an incentive when you connect a battery to a virtual power plant through an accredited provider, once per household. The separate NSW battery installation incentive was suspended in September 2025.
Apartments: the Solar for Apartment Residents grant pays owners corporations up to 50% of the cost of solar. Applications close on 4 December 2026. There's no NSW solar rebate for houses.

Feed-in tariffs and electricity prices

Retailers set their own solar feed-in tariffs. IPART publishes a voluntary benchmark range each year: for 2026–27, 3.4 to 6.5 cents per kWh for an all-day feed-in tariff.

Endeavour Energy applies a two-way tariff to new and upgraded solar connections, charging retailers for some exports. Retailers decide how to pass it on, so a battery that stores midday solar for the evening can be worth more.

From 1 July 2026, retailers in Default Market Offer areas, including Endeavour Energy's, must provide a Solar Sharer Offer with free electricity during three hours in the middle of the day, which needs a smart meter.

Worth asking about in Wollongong

Endeavour Energy's flexible exports become the default for new and upgraded solar from November 2026. Ask installers whether your inverter supports them, and check your Wi-Fi reaches it.
Close to the beach or Lake Illawarra? Ask whether the panels, inverter and mounting are suitable for salt air, and check the manufacturer's warranty conditions for coastal sites.
In a unit or townhouse? Solar and batteries on common property need the owners corporation's approval.
Older homes may need switchboard work before solar or a battery can be connected. Ask each installer whether their quote includes it.
All electrical work must be done by a licensed electrician. Ask for the installer's licence and accreditation details with the quote.
