Michael and Maria McGarvie contracted The Green House Effect to installĀ a 16-bank, 14.4 kilowatt hour (kWh) carbon-gel battery system at their home at Eaglemont, in Melbourne’s east, in April.

After an energy-intensive winter, he said his house has been completely self-sufficient so far this October, meaning he owed nothing to his electricity provider after fixed costs.

He expected his house would be powered completely by his solar and battery systems for nine months of the year

Below is some feedback from Michael.
