Can someone please help me out with some advice. I have a colourbond roof (5 deg pitch) with a ridge line running north south (12 deg East, to be exact). Today I had a 2.28kw system installed and was told that it was not practicle to stand them facing that direction on brackets, in say groups of four or six. Insteadd the installer advised to face them west (282 deg roughly), hence running them in one long line. Is this correct or should I insist on facing them north. Reason given for different direction was that the sun production in summer would more then make up for lost production in winter? In NSW peak power costs are between 2pm and 8pm and he stated due to me being on net metering it is better to make the KW in the 2pm - 8pm time bracket. I live in Lake Macquarie NSW. Any advice would be appreciated. If I do need them altered, will it be a difficult task.
