Of the 20.7 MW of total installed capacity that has been registered for the UK feed-In tariff scheme since it went live on April 1, 6.4 MW was installed by the commercial sector, well ahead of initial government predictions that forecasted the domestic sector accounting for a far higher majority of the installation capacity.

In total, 4,609 installations were registered for the feed-In tariffs with the figures showing a significant monthly increase in the total number of installations being registered. In terms of quantity, the residential market accounted for the lion share of the total number with 4,541 registered installations – a figure that rose from just 408 in April. With the average domestic installation being 2.7 kW in size and all but 112 being solar PV installations, the average financial return for these early adopters can be predicted at £2,000 a year. With an average installation cost of around £12,000, these early adopters will on average achieve an 8 to 12% return over the 25 year lifetime of the solar PV tariffs.

The commercial sector showed a far lower number of installations, with just 55 registered between April 1^st and July 31^st. However, the average size of the installations was far higher and spread more equally between solar PV and wind schemes, as well as 6 hydro-power plants going live.

Although two times that of the average residential installation, the average size of the commercial solar PV installations was the smallest in the sector at 5.7kW. Wind schemes averaged an impressive 106kW but it was the size of hydro-schemes that stole the show with the six registered schemes averaging at 553kW. At this stage, no anaerobic digestion or micro-CHP schemes have been registered, according to Ownergy.

UK as Fastest-Growing Solar Market in 2010

Henning Wicht, PhD of iSupply released a report that predicts installations of PV systems in the United Kingdom will amount to 96 Megawatts (MW) in 2010, up an astounding 1,500 percent from 6 MW in 2009. While the country’s growth will start from a nearly negligible level in 2009, the expansion will dramatically outpace the growth of the next fastest-growing nation—Spain—which will rise by approximately 730 percent in 2010, said iSupply.

“When you think of weather in the United Kingdom, London fog comes to mind more readily than bright sunshine,” said Wicht who is a senior director and principal analyst for iSuppli. “However, things definitely are looking brighter for the solar market in the United Kingdom in 2010, as the country has adopted attractive Feed-in-Tariffs (FIT) to promote PV adoption. Furthermore, with leading solar country Germany cutting its FITs, the focus of the PV world is shifting to places with more favorable incentives—making the United Kingdom a solar hotspot this year.”

While growth in the United Kingdom is expected to slow down from such a blistering rate after 2010, PV installations will continue to rise in the 50 percent range for each year through 2014.
