The first six months of this year have seen solar energy generation in the UK rise 32%, producing a record-breaking 9.91TWh. This massive uptick in solar generation can be attributed to two key contributing factors this summer: record high levels of sunshine and a significant increase in solar PV installations. Domestic solar PV installations are also on the rise, with Ember noting that domestic-scale solar PV installations are at their highest level in ten years. That's another solar energy record, with H1 2025 being the previous record for H1 solar installations set in 2012. The think tank also notes that the average size of domestic solar installations has been rising sharply since the end of the Feed-In Tariff solar subsidy in 2019, which offered better rates for solar installations under 4kW.
