Key facts
- Solar energy accounted for a record 14.4% of Great Britain's electricity generation in July.
- This represents a 50% increase compared to July of the previous year.
- The first half of the year saw the highest number of new solar installations since 2011.
- Household rooftop solar systems are a major contributor to new capacity.
- Favorable weather conditions, including extended sunshine, contributed to the record output.
Solar energy achieved a record share of Great Britain's electricity mix in July, supplying 14.4% of the nation's power. This significant increase, up 50% from the previous year, was driven by a combination of increased rooftop solar installations and favorable weather conditions, including prolonged periods of sunshine.
The surge in solar generation comes as official figures indicate the first half of the year saw more new solar power installations than any six-month period since 2011, with a notable rise in household rooftop systems. This trend is part of a global movement towards solar as a low-cost alternative to fossil fuels.
The additional solar power generated helped to meet higher-than-usual electricity demand, particularly for air conditioning and fans during recent heatwaves. Energy minister Michael Shanks highlighted the importance of domestic power generation for energy security and reducing exposure to global price shocks.
Notable solar projects include the 373 MW Cleve Hill project and the planned 800 MW Springwell solar farm, indicating continued growth in the sector.
