From 1 April 2001 to 31 December 2012, more than 1,731,300 small-scale installations created certificates in the REC Registry and were validated by the Clean Energy Regulator.
Of these, more than 76,161 solar water heater (SWH) and 333,094 small-scale solar panel, wind and hydro (referred to as SGUs) installations created valid certificates between 1 January 2012 and 31 December 2012. Of the SGU installations, solar panels make up 99 per cent of the installations followed by wind (0.01 per cent).
Graph 4: Number of certificates validated for solar hot water and heat pump installations 2009–2012
The graph below represents valid certificates created by the two solar water heater types (solar and heat pump). Solar hot water systems accounted for 84 per cent of certificates deemed in 2012, followed by heat pump water heaters which equated to 16 per cent of all certificates respectively.*
*These figures are based on the date the system was installed and are current as at 27 January 2013. These numbers are likely to increase as certificates can be created up to 12 months after the date the system was installed.
Graph 5: Small generation units and Solar Credits 2009–2012
The graph below represents valid certificates created by small-scale solar panel, wind and hydro systems (referred to as SGUs). The total number of SGUs installed in 2012 was 314,312. Of these around 95 per cent, or 299,462 systems received Solar Credits.*
Graph 6: Small generation wind and hydro systems 2009–2012 activity
The graph below represents the number of systems installed against the number of certificates validated. Solar panel systems were the most popular SGU installed during 2012, followed by wind systems with seven systems installed, receiving 266 certificates.*
Graph 7: Solar panel installations by state 2009–2012
The graph below represents the number of solar panel installations registered by state. The greatest number of solar panel installations in 2012 was in Queensland (38 per cent) followed by Victoria (19 per cent) and New South Wales at (15 per cent).*
