Thousands of Northumberland homes are saving on energy bills with solar power
Energy experts at E.ON UK have analysed GOV.UK data to determine which locations have the highest number of residential solar panel installations across the country.


Northumberland findings
Northumberland’s 12,908 solar panel systems serve roughly 146,900 households, equating to an adoption rate of 9%. These installations mean that around one in 11 homes in Northumberland now has solar panels.
The top five UK locations with the highest number of solar panel installations
One in eight homes in Cornwall now has solar panels, with 31,024 systems across approximately 250,500 households. This corresponds to an adoption rate of roughly 12%, indicating a significant regional commitment to decentralised renewable energy generation.
Somerset follows with 24,603 solar panel systems across an estimated 250,100 households. The resulting adoption rate of around 10% reflects strong community participation in renewable energy.
North Yorkshire’s 22,983 installations are spread across an estimated 274,400 households, yielding an adoption rate of just over 8%.
Wiltshire records 19,794 solar installations across 215,100 households. Around one in every 11 households (9%) now has solar panels, showing that residents are investing in renewable energy.
Aberdeenshire stands out as Scotland’s top solar region, with 17,381 installations across approximately 117,419 households. Nearly 15% of households in the area now have solar panels.
A spokesperson at E.ON UK commented on the findings:
“This data shows the locations with the strongest commitment to renewable energy through solar adoption. Expanding solar adoption across both households and businesses will be key to making the energy transition affordable, sustainable and secure. As technology becomes more accessible and installation costs continue to fall, the path to energy independence is opening for more communities. By investing in solar installations across homes and workplaces alike, we can accelerate the UK’s move toward a cleaner, self-sufficient energy future that brings lower bills, stronger local infrastructure and greater energy security for everyone.”
