Just had my new Sigenergy solar system installed and I couldn’t be happier! Sam, Justin, Ben, and the entire team were awesome — super prompt, efficient, and really professional. They made the whole process completely stress-free and helped me make sense of the solar maze. Couldn’t recommend the team more highly!

Daniel and the team have done an excellent job setting up our new solar + battery system today. Very professional approach and good flexibility on the day with negotiating a suitable pathway for conduit and battery/inverter location. Hot conditions today but the install team just got on with it and got the job done with no fuss and no issues.

The whole process from pre sales to post install support has been fantastic. The install team operated like a SWAT team, everyone knew their roles, effortlessly efficient, panels, heat pump and battery all fitted within 6 hrs. Left the place spotless. Can’t speak highly enough about these guys. Very happy.

Frequently asked questions

How much do solar installers typically charge?

Solar costs vary widely depending on system size, equipment choices, roof access and whether additional electrical upgrades or battery work are required. Simple panel adds or routine maintenance are typically much less involved than full system installs or battery integrations. This page shows live pricing to help compare current rates alongside the specific scope of your job.

Do solar installers charge call-out fees?

Yes — call-out fees are common for solar installers and are often charged to cover attendance and an initial assessment. Call-outs are usually separate from hourly labour and materials, and after-hours or emergency visits typically attract higher rates. Confirm whether a call-out fee is included or listed separately when comparing quotes.

Do solar installers need a licence in Australia?

Yes. Solar installation work is required to be carried out by a licensed installer in every Australian state and territory, and in NSW installers are licensed through NSW Fair Trading. Many installers also hold industry credentials such as Clean Energy Council accreditation and may display a valid state electrical contractor licence on quotes, as well as public liability insurance. These credentials can help indicate the installer has relevant training and compliance practices.
