Battery storage — new installs and retrofits

The energy audit was the part that impressed us most — they came out, looked at our actual bills and roof, and told us honestly what would and wouldn’t work. No upsell, no pressure. Install was done in a single day by the same crew who quoted us. First quarterly bill was $31. We’ve told every neighbour.

Three companies quoted us. Two gave us a PDF with specs and a price. Green Tree Solar walked us through exactly how the system was sized to our daytime consumption pattern. Different conversation altogether. The monitoring app they set us up with paid for itself the first week when it flagged a panel shading issue.

Already had a 6.6 kW system from 2021. Green Tree Solar checked whether our existing inverter could handle a battery before agreeing to do the job — another installer had already said yes without checking. Honest call saved us from buying equipment that wouldn’t have worked. Retrofit took about five hours.

Being NETCC Approved meant the consumer code protections applied — that was important to us before committing. The paperwork on our end was minimal; they handled the network application and the metering changeover. System has been producing more than the estimate since day one.
