sunnier in morning or evening?

wazzoraybelle · 2008-04-11 13:29:57

Hope someone can help me with this. Is it more likely to be sunnier in the morning or the afternoon? The reason I'd like to know is for siting solar panels (thought this would be a better forum than R.E. for this info. TIA.

I'm open to correction here but I'd say its sunnier in the morning.

This is because convection usually occurs during the day and can take a while to clear in the evening. On the other hand, its usually colder in the morning.

Posted here yesterday evening

Generally there is more sunshine in mornings as convection increases cloud during day.
When do most showers occur?
In the afternoon.

I have sunshine data going back 4 years here in coastal Wicklow.
Here are total sunshine hours for each hour. The hours are set for true time and not based on GMT
6-7 300h
7-8 418
8-9 532
9-10 620
10-11 646
11-12 639
12-13 606
13-14 578
14-15 536
15-16 447
16-17 345
17-18 240

The above is specific for my site, but I say the trend is same for most areas
