Charles listened to what I wanted and came up with exactly the same recommendation as another potential supplier. The difference in price for identical quotes being the main differentiator. Matt, who was the installer, could not have been more helpful and everything was fitted extremely neatly and the whole area cleaned before they left. He also was at pains to point out that we had bought a top of the line system - which if nothing else - made us feel better! The combination of the Fronius Primo 5.0 Inverter and 18 x LG Neon 330w panels (giving 5.94Kw) should ensure that our needs are easily met and once the power company starts to pay us for the excess generated I foresee savings in the region of $2500 pa, which means a payback period of about 4 years. None of this could have been achieved without the expert advice of Finn - especially over-sizing the system - and the expert installation of Matt who found a way of installing the 18 panels and still leaving reasonable access. Our thanks to all.
