A heat wave that is expected to send temperatures soaring as high as 35c in the UK this week will have a significant impact on PV generation figures.

This week’s heat wave, caused by a concentrated warm front and “tropical continental air mass” arriving from southern Europe, looks set to trigger hottest days of the year on successive days this week, with forecasts for clear skies extending until Thursday afternoon.

And the weather is set to cause a surge in solar energy generation, particularly in the south of the country with generation in London and the south east especially high in comparison to last year.

Figures compiled by sustainable energy agency SevernWye for the period inclusive 29 June to 1 July show that potential PV generation in London is expected to rise by more than 38% year-on-year to 55.1KWh, with similar boosts across the country also expected.

Weymouth is a close second in terms of strong solar PV potential across the three days and is expected to generate 53kWh, a 12% increase on last year’s figure of 47.2kWh, while Cardiff and St David’s will also benefit from the heat wave by posting above-average yields of 50.4kWh and 50kWh respectively.

And actual PV generation could be even higher than suggested as Karen Robinson, project manager at SevernWye, said the forecasts are based on conservative estimates.

Parts of the UK are however expected to miss out on the weather, most notably Scotland with the country’s capital Edinburgh expected to witness a 31% slump in PV generation over the three-day period to 35.5kWh.

“Solar is such a proven technology, an average household installation can comfortably generate more in terms of kWh than a household is likely to use in summer months, what we could do with now is some kind of storage mechanism that really allows us to capitalise on this,” Robinson said.
