What a system should cost, what it should save, and the things about a particular part of Melbourne that change the answer. Housing stock, the electricity network the area sits on, and the site issues that come up often enough to be worth knowing before you get quotes.
Check my home, free408 guides so far, with more being added. Grouped by the Victorian Government's metropolitan Melbourne regions.
These sit in more than one council, and the councils fall in different regions, so they are not filed under one.
Each guide describes what homes in the area are commonly like. It is context for reading a quote, not a statement about any particular property. Roof material, orientation, shading, pitch and switchboard all vary house to house on the same street.
Melbourne is split between five distribution networks, and the boundaries do not follow suburb lines. Where a suburb sits across two, the guide says so. The exact network for an address is confirmed against the Victorian Government's own records during the assessment, never guessed from the suburb.
Rebates, feed-in tariffs and payback are worked out identically for every Victorian address. A suburb guide changes the context around the number, not the number itself. The methodology sets out every assumption.
The assessment works off your actual address, bill and usage, so it answers for your home rather than your postcode.
