I have just ordered and paid a deposit for a Tesla Powerwall 2, I would been keen to hear from other NZ owners.
Telsa are sending someone round to do a quote in January. It is expected to cost $13K to $14K installed. The deposit is refundable.
My place in Christchurch has a PV system with 15 x 270 Watt panels with Enphase M215 micro inverters. I have 3 phase power, so there is only 5 panels per phase. I often export on 2 phases and import on the other! This makes my system very inefficient, hopefully the battery will help with this.
Like most people I really only have excess supply in the summer. The aim is to top up the battery with cheaper night-rate power at other times.
Solar without a battery you are limited to power retailers who support buy-back. Once the battery is installed I can look to switch to a retailer like Flick which should help reduce my bill even further.
How have you found your Powerwall? Any tips? What was the impact to your monthly bill?
