Problem is that inverters will fail before the panels. People will be tipping in lots of $ down the track to get new ones.
And panels also will lose efficiency over the years.
The price of the current systems even after rebates needs to halve again before I'll put it in.
Good news is that a friend who owns a large solar buisiness recons in a year or 2 the big manufactures will have systems half the cost of now. The market is getting too big for them not to mass produce.
