Great Britain solar panel installations hit 15-year high amid soaring fossil fuel costs

Key facts

• Great Britain installed 142,536 new solar power systems in the first half of the year.
• This is the highest number of installations for a six-month period since 2011.
• The surge is driven by households seeking to lower energy bills amid high fossil fuel costs.
• Government grants for heat pumps have been increased, and VAT on electricity bills has been reduced.
• Energy suppliers like E.ON Next and Octopus Energy reported significant increases in solar panel installations and sales.

Great Britain has experienced a significant surge in new solar power installations during the first half of the year, reaching levels not seen since 2011. This trend is largely attributed to households seeking to reduce their energy expenses in response to soaring fossil fuel costs. Official government figures indicate that 142,536 solar installations were added in the first six months, positioning the country to surpass last year's record.

While rooftop solar panels on homes constitute the majority of new installations, they account for less than a third of the total solar power capacity. Energy companies report that consumers are increasingly adopting solar to generate their own electricity and store it, thereby decreasing reliance on the national grid and lowering bills. Some customers have reported annual savings of up to £600.

Government initiatives, such as increased grant funding for heat pumps and a reduction in VAT on electricity bills, are also contributing to a shift towards lower-carbon heating alternatives. E.ON Next observed a 151% increase in home solar installations, while Octopus Energy noted a 54% rise in sales following geopolitical events that impacted oil and gas prices. Legislation passed this month will also enable residents in flats and rented properties to utilize balcony solar panels by August.

Newer solar projects are substantially larger than older ones, with developments like the 373MW Cleve Hill solar farm and the 800MW Springwell solar farm demonstrating the growing scale of solar energy infrastructure in the UK.
