According to the first edition of a new quarterly report of sun and solar, July was the UK’s sunniest on record and led to small-scale solar producing up to 3.1 terawatt hours between July and September.
Reportedly, the South East, South West and East of England produced an estimated 44% of it between them.
The UK Solar Report, created by MakeMyHouseGreen, also detailed that output was an estimated 13.6% above an average summer, while every region beat its long-run average. This was led by London and the South East at 19.2%.
On a south-facing roof, each kilowatt of panels produced an estimated 394 kilowatt hours in the South East, the most in the UK, and 289 in Scotland, the least. London, the South West and Wales were close behind the South East.
Llewellyn Kinch, chief executive of MakeMyHouseGreen and Switchd, said: “This was a great summer to own solar panels. Across the UK, they produced an estimated 13.6% more electricity than in an average summer. What a solar home gets back also depends on its tariff.
“We modelled 1,281 of our customers in Great Britain using typical summer weather, and every one of them would have paid less on the cheapest tariffs we compared than on the standard price cap tariff. The typical home could have saved £63 over the quarter.”
On those tariffs, more than a third of the homes (35.4%) would have earned more from selling electricity than they spent buying it. On the price cap, fewer than one in five would have.
