Frequently Asked Questions

Taking into account all the options, home solar panels cost from $3,000 – that is, for a top of the line solution. At that price, you can get a reliable and high-quality 6.6kW system.

Whilst there are costs to you in purchasing and owning the solar system, solar power will help you to reduce your monthly electricity spend by offsetting the energy usage in your house. How much your monthly electricity bill will reduce by will depend on a number of factors, including the size of the system that you install, how much electricity your system generates, and how much electricity you use during the day.

Solar photovoltaic panels require little maintenance. Your panels can build up dust and other material over time. Solar panel cleaning is not that different from cleaning your windshield. This can be done with water and a soft brush.

All installations under 100kW (and systems with an annual electricity output of less than 250MWh) are eligible for Small-scale Technology Certificates, or STCs for short. You’re eligible for STCs whether you’ve previously accessed a rebate or not. It’s also not means-tested and is accessible by everyone. The solar PV system or product you purchase in order to receive STCs must adhere to the Clean Energy Council (CEC) design and install guidelines, only use panels and inverters on the CEC approved list, comply with the relevant standards (like AS 4777), and be installed by a CEC accredited installer. CG Energy meets all these requirements. In addition to STCs, your state may offer an additional rebate or program. These rebates differ between regions, so it’s worthwhile investigating what solar rebates apply in your area.

If your roof is in good condition, and gets a lot of sun, it is probably a good candidate for solar. We do not recommend installing solar on old roofs. The panels are expected to last for over 25 years so it is not recommended to install them on a roof that may need replacing during the life of the system.
