Very professional, from start to finish, we had a good experience with installation of our 5kw system. They took care of all the external paperwork and bits and bobs very efficiently and guided us through rebate process. Only paid $2.5k up front for quality system, have taken out interest free loan from Vic solar for remaining amount, very happy with investment and now generating and pumping back into grid. Have heard some horror stories re solar installation, so we are very happy and would definately recommend these guys!
