27 December 2015. It is interesting to see several Adelaide home building companies now offering solar panels as part of their offering. Adelaide and South Australia have embraced solar installation (as a percentage of dwellings with solar power installed) more than any other capital city and State in Australia. As the cost of solar battery storage systems drops we expect to see fully integrated solar / battery systems being offered as a ‘standard’ inclusion in new homes in Adelaide over the next few years. This option makes the possibility of using solar energy stored during the daytime and used at night time a reality and this will certainly represent the next stage of ‘evolution’ in residential solar power usage in South Australia.
