Domestic PV installations in Denmark have grown exponentially in 2012 reaching 223MW this month from just 17.5MW at the end of last year.

But the explosion has been driven by the success of Denmark’s subsidy programme, which is now under government review.

According to the latest figures published by the country’s transmission system operator Energinet, obtained by PV-Tech, Denmark had 42,405 individual domestic PV installations as of 9 November.

At the end of 2011 this figure stood at just 3,734 – the equivalent of around 17.5MW of installed capacity.

But such has been the success of Denmark’s PV subsidy programme that the country’s Energy Minister Martin Lidegaard is now considering revising the scheme.

Last month Lidegaard told Danish media outlets that the programme costs the Danish treasury some €270 million annually and could not continue in its current form.

There have also been reports that the boom in domestic installations has led to poor practices, with improperly or hastily installed systems damaging rooftops.

Lidegaard is expected to publish proposals for a revised subsidy programme in the coming months.
