The Productivity Commission has warned solar PV is a very expensive technology, which has cost up to $1043 in subsidies for every tonne of CO2 that is abated and could hold back deeper cuts to emissions. This contrasts with the $23-a-tonne starting price for Labor's carbon tax.

The federal government has cut incentives for householders who install solar roof panels in a bid to take heat out of the solar panel market.
