Hi Dallas
Environmental Upgrade Agreements only allow for non-residential dwellings and only for residential strata schemes of more than 20 lots. The Act is pretty specific in what you can charge ratepayers.
I do know that Ku-ring-gai offers a Solar rebate which was paid after purchase towards invoiced material and installations costs. Rebates were subject to availability of funds and must be pre-approved. Rebates were not given to works required for either BASIX or development application compliance.
