Renewables: "talking 'bout my generation"

Markj1110

5.21 O's yesterday, a Hawaii, 2 on the trot! :j Helped me get to 94% of PVGIS for March.

First 5 O day yesterday since September.
Month ended with 93% of PVGIS.....with 29% of it coming in the last 5 days!
Imported 270 units....first month since September generation has exceeded import.

Is today the first day of increased tariff`s? Do we know the % increase this year, or is it different for everyone (depending on when your system was commissioned).

Ended the month with 102.7% of PVGIS mostly due to the very good final week.

rodee13

achieved 337kWh with a target of 310kWh for March (reduced target due to slight shading in first 15 days of march)

edwink

Achieved 249kWh against target of 291kWh for March. Our target is the actual target given on PVGIS for our 3.36kWp system with no deductions made for shading from our neighbours trees for the whole of March.

March results were ok, got 357.1kWh, 105% of PVGIS gross target.

All systems pretty balanced, 105% on the ESE and 106% on the WNW.

Import was 131kWh (target 130), but April is when it really drops, target 100kWh.

Bit of fun, thought I'd see how my best, and worst months compared against target, so added up best Jan, Feb etc, and worst Jan, Feb etc:-

Target 4,247kWh
Best 4,909kWh = 115.5%
Worst 4,015kWh = 94.5%

Surprisingly narrow spread, and with the upgrade to PVGIS, since I did my figures of ~5%, that would give me a range of roughly, 90% to 110%. rather boring results, from a rather nerdy experiment, who'd have thought. :think:

Thank you all for your very helpful responses. I'm quite stunned by the effort you have all gone to (including providing your own data) to reassure me.

There is a little winter shading which has probably had more of an effect than I anticipated. On the whole it looks like the panels can perform as this is a summary from their peak performance (ever) yesterday afternoon.

259w West facing 20o
256 West facing 20o
243 West facing 35o
245 West facing 35o
242 West facing 35o
242 West facing 35o
245 West facing 35o
349 South facing 35o
341 South facing 35o
346 South facing 35o
337 South facing 35o

Total 3.068 Kw

So for each of the three banks all the panels appear to be performing fairly consistently. (I also don't understand how the South panels achieved over 340W).

For the day, I got 4.56 O's so perhaps I've just been unlucky with the weather (brighter mornings and duller afternoons not favouring my layout) and an underestimate of the winter shading. Also per Martyn's earlier question, the 20 degree panels achieved 8 times there Dec output in March so presumably that ratio will increase as the sun gets higher? March over all was 75% of PVGIS

With 3 aspects I was about to start worrying about string and string voltages but I see you have optimisers so not a problem.

If you look at historic panel data you should be able to see if there have been any shading issues.
