4 weeks on from the install i am yet to turn my panels on. The cheap prices cover incredibly poor after sales service. I have rung half a dozen times and received just as many differing updates - each contradicting the last. I have been sent to my retailer and distributor on multiple occasions - neither of which have received any info from TVS. RIght now ive got a $4000 system sitting on the roof doing nothing else than weighing the house down ever so slightly. Unless you want a similar experience i would AVOID.....

Approximate cost: $4000
