To ask the Secretary of State for Business, Enterprise and Regulatory Reform what estimate he has made of the number of solar panels installed on (a) domestic and (b) non-domestic properties in each of the last 10 years.
We commissioned a report on the potential for microgeneration in 2005, estimating that there were approximately 82,000 microgeneration installations in the UK. There are now estimated to be about 100,000 systems. We are not able to break this figure down by technology. However, since 2002 we have provided funding for 11,278 solar installations through our grant programmes, with the details shown in the following table.
|Grant programme||Period||Technology||Number installed|
|Solar PV Major Demonstration||2002-07||Solar photovoltaic||1,829|
|Low Carbon Buildings Programme Phase 1||2006 to present||Solar photovoltaic||727|
|Low Carbon Buildings Programme Phase 2||2006 to present||Solar photovoltaic||127|
|Clear Skies||2003-07||Solar thermal||5,799|
|Low Carbon Buildings Programme Phase 1||2006 to present||Solar thermal||2,774|
|Low Carbon Buildings Programme Phase 2||2006 to present||Solar thermal||22|
We have commissioned further research to provide up to date estimates, and this will be published in June 2008.
