I had a 3KW system installed in March, 2013. During my discussions with TVS they consistently told me that I needed to do nothing whatsoever, and simply allow them to install. After Installation I received a complaint from my neighbour about the panels, and was told by my local Town Council I should have applied for a Development Approval. When I confronted TVS local office about this, they said it was not their problem, and my sole responsibilty. This was confirmed in an email by Melbourne office.
I have now applied for a retrospective DA, and will undergo a hearing with out Town Council. TVS have washed their hands of this matter, and are avoiding any contact. I advise anyone who does business with TVS to verify in writing about getting local council approval, before installing solar panels. TVS deny it is a requirement, but in the odd case where a neighbour has the right to complain, make doubly sure with your local council. TVS WILL NOT support you, and they do a "Pontius Pilate" .

Approximate cost: $4,600
