Tamz I don't ever post stuff on here or use this site as a rule because it's just full of DIY nut jobs that don't have a clue what they are on about. But last night while looking at some solar discussions I came across this post by chips and thought ok I'll point him in the right direction as sometimes you have to pass on done knowledge.
And then you post the above and it confirms all my thoughts, you clown. If you don't have anything constructive to say or don't understand what people want then don't say it. And if your qualified god help you.
Chips please message me, coz after this I'll be more than happy to help you.
