Solar Dynamics installed a 5kW (18 panel) system here in Jan 2022. They were very helpful and informative in explaining everything in the lead-up as well as providing various options and recommendations with reasons, which all made sense.
Instalation just took a morning and was very efficient and the installers were very professional and polite. The paperwork process is quite long due to the State government bureaucracy around it but Solar Dynamics did everything they had to do at their end immediately.
In summary, they were fantastic and I would highly recommend them. We had no issues at all and the system is up and running along nicely.

Approximate cost: $6300
