In 2015 I moved into a new house which at the time was using a whopping 85 kWh/day on average in winter and not getting below 45kWh/day across most of the year. I straight away installed a large 10 kW solar pv array. A lot of this power was being exported to the grid during the day and we were still using a lot at other times. I wanted to try and use more of the power I was making, this posts tracks the journey through that process.
Across Australia most new solar installations are subject to tariffs which pay the owners as little as 1/4 or less for their excess power that they export to the grid during the day than they are charged for using the same power through the evening hours.
Installing a battery system in your home allows you to instead store this excess electricity and use it yourself, avoiding the high tariffs.
