We installed a 3kw solar system at home in January but are still tied to the grid (in New Zealand btw). Due to the placement of the panels we should see no bills in summer and in winter it should reduce by 50%.
It should have paid for itself in 11 years, but in 10years if we decide to stay we will extend the house and add another 4 panels and replace the inverter, and hopefully the technology in batteries has advanced enough to allow a bank of batteries to be added to the system cost effectively.
