Solar hits record 14.4% of Great Britain's electricity in July 2026

Solar supplied a record 14.4% of Great Britain's electricity in July 2026, up from 9.6% a year earlier, per National Energy System Operator data. Ember analyst Frankie Mayo calls it the UK's "second solar boom." The surge spans rooftop and utility-scale buildout, with 142,536 new installations in early 2026 — the most for any six-month period since 2011.
