today's production

[infinity]

It's 1650 with some time remaining for a little more production.

I have produced 22KwHrs so far today
3.5kwp system, 250w ET solar Poly's
Ever solar 4000TL

My roof faces south east on a 50deg pitch

I think the output is pretty food considering its what would be classed as a budget system!

I'm on south coast BtW does anyone.
Have something to compare it to of a similar setup?

You are doing well.......I'm up in North East Scotland so comparisons are not relevant....but of our customers who have SolarEdge the average for a 4 kwp system so far to day has been 18.50 kw for a 4 kwp system.

The weather here today has been mostly cloudy....but there has been good spells...

I'm on 31kwh with a 6kw east/west split system and still producing 2kwh at the mo

 

[reelectrics]

one of my clients 8kw sma tri has done 63kw today and 250kwhr in last 6 days.Spring at last

I'm on 24kWh on a 4kW SW system nr the River Humber:smilielol5:

Has been a good solar day methinks! ;-)

System stats in my signature.

22.78kWh generated on Saturday 20/4 - between Cambridge and Ely.
The weather on Saturday was full sunshine - not a cloud in sight all day.

Our best day of the year so far. Today looks like it'll be good too - I'll try to report back later.
The power output nudged through 3.0kW about half an hour ago. The graph is close to plateau so doesn't look like it'll reach the full 3.6kW today; more likely peaking around 3.3kW peak output.



I get my best generation on days where it is clear sky in the mornings and then gradually a bit of thin white cloud appears in the afternoon - the white cloud helps reflect the light back onto my ESE-facing panels after the sun goes behind them. I get into mid-20's on such days.

Although the stats for my ESE-facing system may not look remarkable, the SAP methodology does not take into account that solar performance drops off rapidly outside the SE-SW azimuth. The 22-degree difference between ESE and SE is as great as the 45-degree difference between SE and S.

Another interesting performance stat is someone I know with a 4.0kWp array - 2.0kWp faces South at 30 degrees and 2.0kWp faces North at 30 degrees. Panels and inverter same as me.

It had an SAP target of 2800kWh generation. It recently reached that about a month early, and looks set to outperform its annual SAP by about 16% with an expected 400-500kWh in the next month.

My ESE-system at 40 degrees outperformed its annual SAP by about 10% (as per signature), so the N/S split system is doing really well in a like-for-like basis.

The person with the N/S system actually had an installer knock on the door several months ago and say "did you know your panels are on the wrong roof?".

23.9kwh on 6th April is our best so far this year. We're ESE, 30 degree pitch in NW England and our system is 2.5 years old with a telephone line running diagonally about 300mm above the array - no sign of degradation yet. We haven't had temperatures above 14 degrees yet this year - much better than anticipated.

 

[FB.]

I'll try to report back later.

22.78kWh on 20th April (best day this year).
21.19kWh on 21st April (second-best day this year).
System here:
Cambs S P 3.750kW
(readings taken from Landis&Gyr E110 generation meter; not from the often-unreliable add-on energy monitor devices).

Weather data for Cambridge is reported here:
Digital Technology Group - Cambridge Weather - 13.6 C

My ESE-facing system tends to reach peak power mid-morning, so the air tends to be a little cooler at that time, theoretically giving a slight boost to production due to temperature coefficient.

23.9kwh on 6th April is our best so far this year

22.78 on 20th April is the best I've got so far this year. If I had a 4kWp system rather than 3.75kWp it'd scale-up to about 24kWh for the day; in-line with your 23.9.

Mine is monitored with Passiv, SMA Sunnybeam, Owl & Elster but I use the Sunnybeam for accuracy (others are for testing for our customers)

Interesting that you are so much further south than us but still generating similar figures despite our shading.

4kw South facing in Boston Lincs.

28.2 kw Saturday 20th
22.5 KW Sunday 21st ( bit cloudier in the afternoon)

SMA SB3300 inverter (3.6kw) 4kw panels.

In these parts, our best weather is in the autumn. East Anglia is known for its generous quantities of autumn sunshine - and Met Office data agrees:

The following chart (a bit out of date now) shows my generation last year and the autumn-sunshine phenomenon stands out really well - my generation tracking the SAP target until autumn, then a huge acceleration above trend until generation tailed-off for winter:

In addition now April has finished, a 510kw generation figure.

A very good April compared to last year
