Investment by Australian households and businesses in small-scale renewable energy systems grew strongly in 2019:
-
24 per cent increase in the number of small-scale solar PV installed compared with 2018; almost one in four households now has a small-scale solar PV installation.
-
2.2 gigawatts of small-scale solar PV capacity installed (a 36 per cent increase on 2018), bringing the cumulative national total to 10.3 gigawatts.
-
16,100 gigawatt hours of electricity generated or displaced by small-scale renewable energy systems.
-
35.8 million small-scale technology certificates validated.
The average size of small-scale solar PV systems increased in 2019, up by six per cent from
7.2 kilowatts in 2018 to 7.6 kilowatts in 2019. Installations of mid-scale solar PV systems
(15 to 100 kilowatts) on businesses, schools and commercial buildings and households choosing larger sizes of solar PV installations are factors driving this increase.
