FAQ Melbourne

Do you have any questions for us?

If you have any questions or would like more information, please get in touch with us using our contact form.

How long does it take for 1KOMMA5° Melbourne to install my order?

The current waiting time for a solar system with battery storage and EV charger is 2-4 weeks after purchase, not including the time to process the documents needed for the Victoria rebate.

What government incentives are available in Melbourne?

Small-scale Technology Certificates (STCs) are a federal government incentive in which homeowners receive certificates for the solar energy their system will generate over a set period. These certificates can then be sold to help offset the upfront cost of installing solar panels.

In addition to STCs, Melbourne homeowners may also be eligible for the battery interest-free loan of up to $8,000, payable over four years.

To find out if you qualify for any government rebates or incentives, please contact our team.

A fully installed 5kW solar system in Melbourne costs $6,000 to $8,000. Meanwhile, a 10kW solar system generates around 36 kWh, and prices range from $11,500 to $15,500.
