I can imagine. I think Energie Group has the best offer, so it’s worth finding out more about them. I’ve got some questions in this chapter in the Guide to Buying Solar that will help:

Secondly, I think it’s worth reaching out to a reputable solar installer in your area. I listed a few in our Solar Installers Perth page which get good reviews. Solaire Connect in Joondalup gets good reviews, they sell Fronius and REC which is a good combo.
Let me know how you go.
Cheers
