Melbourne Solar Rebates and Incentives in 2026
Eligible Victorian households can apply for a Solar Victoria solar panel rebate of up to $1,400. An optional interest-free loan of up to the matching rebate amount may also be available, subject to approval. Federal Small-scale Technology Certificate (STC) discounts may apply to eligible installations. Eligibility conditions include household, property, product and retailer requirements. You must obtain approval before installation to receive the Victorian rebate.Important: A loan is repayable and is not an additional grant. Do not assume every advertised price can be reduced by the full rebate again. Confirm the quoted net price and current rules with Solar Victoria.
Is a 10kW Solar System Worth It in Melbourne?
A 10kW system can be valuable when a household uses substantial electricity during daylight hours or expects higher future demand. Electricity consumed directly from solar can offset grid purchases; exported energy may earn a lower feed-in tariff, subject to the retailer and network arrangement. For an illustrative calculation, if 12kWh of solar energy each day replaces grid electricity priced at $0.30/kWh, the gross avoided purchase value is $3.60 per day. This is not a guaranteed saving and excludes other electricity use, export earnings, seasonal variation and system costs. The right assessment compares your interval electricity usage, estimated solar generation, daytime self-consumption and the installed quote.10kW Solar System with Battery in Melbourne
Adding battery storage can allow some surplus daytime solar generation to be used in the evening. Australian Design Solar offers selected solar battery packages from $5,999*, separately from the advertised solar-only starting price.
Battery costs depend on usable kWh capacity, inverter compatibility, electrical work and whether blackout backup is included. A 10kW solar array is measured in power capacity; a 10kWh battery is measured in stored energy.
