I'm curious, how much per kWh are you buying the power and how much are they buying it back of you for?
I am not sure solar electricity is worth or not. It is very expensive to use solar power and efficiency is very less.
I was on the fence about Solar for a long time and therefore missed out on both the 60c kw/h and 20c kw/h rebates in NSW.
Because electricity cost is continuing to increase we have now decided to bite the bullet and are puchasing a 3KW system (with 5KW inverter) from Nicholls Solar (12 x 250 watt Trina panels + 1 x JFY Suntree 5000 TL 3 phase Dual MPPT inverter ) .
10 year installation warranty and 10 year inverter warranty
This system should produce an average of 12KW/h per day or better. The trick will be to try and use as much of that each day as possible .
Expecting payback period to be 5 years (less if power prices continue to increase)
