Solar in Glasgow

Glasgow sees fewer sun hours over the year, but Scotland's very long midsummer days mean a good June day can still be productive. Winter output is low, so timing appliances to the forecast matters more here than anywhere.

How to tell if today is worth it

The annual averages above set expectations, but any single day in Glasgow is driven by cloud. The free Sun Hours app takes your postcode and your system’s best-ever day, then gives Sol’s personalised 7-day forecast — so you know whether to run the washing machine now or wait for tomorrow. Setup is two questions and there’s no account.

Thinking about a kit? Plug-in and balcony solar became legal to plug into a standard socket from 27 August 2026. See the plug-in solar guide and balcony solar UK page.
