Solar PV market continues grows in July

06 August 2019

The latest figures from the Clean Energy Regulator (CER) show that Australia’s roof-top solar PV market (less than 100 kW) continues to grow through 2019 and is on track to achieve installed capacity of more than 2,000 MW this year.

All states experienced a growth in the number of installations in July. Lower June 2019 figures were largely due to fewer number of working days in the month compared to May and July.

Data is based on the month in which solar PV systems claim Small-scale Technology Certificates (STCs), which tend to lag the actual date of installation. To determine residential systems, we use a proxy of 15kW, with all systems above 15kW assumed to be commercial.

Victorian residential installations falling as all other states increase

The growth in commercial installations in Victoria masked a significant reduction in the number of residential systems claiming STCs in July. The Victorian Solar Rebate program was halted in April this year which meant that the level of installations slowed from May year and the lag in creation resulted in very low levels of STCs created in June and July.

The solar industry in Victoria is currently going through a contraction period, which will continue for some time as the Victorian government has announced a cap of 42,000 rebates for the 2019/20 financial year. The government’s policy commitment was to support 650,000 PV systems over 10 years, and it appears that this has been considerably back ended.
