We hit >21 once in August, quoting reputable sources - average has been closer to 17-18.Any idea what your total yield per day has been lately? Did some figures last night as baby wouldn't sleep, suspect I messed up somewhere though. Figures seem to think in August I'd have got about 21kwh on average
If it helps, i don't actually know what any of this means.
My reputable source is always happy to talk numbers, and actually made me make this post.
