Jan was rubbish month for solar

[Everest]

Looks like we were 20% down on solar generation in Jan 2026 compared to last year Only made just over quarter of mega-watt hours this month, not much better than December - whereas Jan 2025 was over 320kWh.

Was it equally bad in other parts of the UK?

Down about 5% on last January, but the same as December 2025 - equally bad.

A paltry 74.50 kWh for us in Oxfordshire.

However, looking at reports from Givenergy (if these are reliable, which I'm wondering about) we got:

• 57.06 kWh in 2025
• 141.39 kWh in 2024

I wonder if January has been particularly wet and mild.

Our heat pump has been getting great efficiency, though I don't have any comparison to other years.

10% down for me 126 vs 138.
