Don't believe the sales pitch. They will tell you that you can get a 20 cent per kwh rebate but will leave out that you will pay more for grid electricity on that plan. They don't mention anything about you needing to organise a new meter. Also, the initial design was totally inaccurate and therefore the quote was bogus. The organisation of the interest free payment is really clunky and requires multiple contacts to organise payment. The end result for me was instead of paying $3600 for a 4.8kw system on a plan with 20c feed in, I have a 4.1kw system that cost $3700 and is on a plan with an 8.6c feed in tariff. Save yourself the hassle and use someone else. Not my best decision.

Approximate cost: $3700
