How much power does solar produce in Sydney?

Solar systems in Sydney will naturally output more power in summer and less in winter.

As an example, a 5kW solar system in Sydney facing north with no shade will output an estimated 20kWh a day, averaged across the year, or around 7,100kWh over 12 months. Meanwhile, a 10kW solar system in Sydney will provide 39kWh of power a day or around 14,200kWh over 12 months.

How much do solar systems cost in Sydney?

The cost of solar panels in Sydney depends on your system size, which will be determined by different factors such as your current energy bill and usage, as well as your roof size and budget.

As a guide, a fully installed 5kW solar system in Sydney costs from $5,000 to $8,000 and can save homeowners $1,800 a year.

Meanwhile, a 10kW solar system in Sydney costs from $7,000 to $13,000 with annual savings estimated at $3,000.

What solar rebates are available in Sydney?

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. To find out if you qualify for this incentive, please contact our team.

How long does it take for 1KOMMA5° Sydney to install my solar system?

The estimated lead time for a solar system with battery storage and/or an EV charger in Sydney is currently 2-4 weeks from the date of order confirmation. Once you place your order, our solar installation coordinator will reach out to you and schedule the installation time as soon as possible.
