Jonathan Whiting Last updated on 25 March 2020 2 min read Solar power in the UK almost doubled last year with plummeting costs causing a boom in the UK’s solar industry.By the end of 2014, there was almost 5GW of solar photovoltaic panels installed, up from 2.8GW at the end of 2013.Despite reductions in the Feed-in Tariff by the government, the average price of solar panels has reduced by 70% over the last few years meaning solar is still an attractive prospect to many home owners in the UK and is now much more affordable.But which regions of Great Britain are leading the boom in solar installations? The map below (click to enlarge for a more detailed map) shows which regions of Great Britain have the highest number of domestic installations per 10,000 households based on official data by the government.Regional DataRegion Installations per 10,000 homesSouth West378East Midlands300East of England273North East252Yorkshire & The Humber244South East213West Midlands194North West178London48WALES283ENGLAND219SCOTLAND159South West of England leading the wayThe South West of England is leading the way with 378 installations per 10,000 households. Mid Devon was the best performing local authority with a whopping 949 solar installations per 10,000 households. Eight of the top 15 local authority areas were in the South West of England.Wales beats England and ScotlandAs the data table above shows, Wales has a higher number of installations per 10,000 households (283) than England (219) and Scotland (159). Wales has 2 of the top five local authority areas for GB, with Monmouthshire at position 3 with 740 solar panel installations per 10,000 households, whilst Wrexham is in position five with 685 solar panel installations per 10,000 households.London not pulling its weightThe 14 bottom local authority areas are all within Greater London. Tower Hamlets was bottom of the list, with just 10 solar installations per 10,000 households. London clearly has some catching up to do.For maps of individual regions please contact jon [at] theecoexperts.co.ukMore maps from The Eco Experts – The countries with the most threatened mammals – Countries most likely to survive climate change – Places in the UK that fracking will impact most Jonathan Whiting An eco hero with a head for numbers, Jon’s data visualisation skills are legendary.
