The profound reduction as we head into late autumn is very apparent. My 30-day average to today is 3.68 units while the average since I started has just gone below ten at 9.84 units. Still hoping it stays above 6.85 units come 18 May. Overall, I think the panels are performing to expectations or better. It will be interesting to see how much the deepening winter will cut the power further.
One other thing. I sent a meter reading to EDF on 13 September which should yield over £550. This has still to appear in my account. I phoned them after six weeks and it was nicely pointed out that payments can take up to 90 days. I hadn't expected that. At this rate, my summer peak will arrive in time for Christmas.
