The sunnies in here now and when it firzvrespiear well be inbtge shade on our elevation.
16 hours my arse.

Cold and cloudy here, rain expected.

Sunrise: 4:43 AM
Sunset: 9:25 PM
Daylight Hours: 16 hours and 42 minutes

That is based on your location (midlands).

His precise sunrise is 4.45 am
and sunset is 9.38 pm
Just in case he wants to split hairs

The correct answer for today is 16 hours and 24 mins.

quit making stuff up

 

[motorbiking]

That, and quit making stuff up for the same end

That extent being, given that the sun won't be beating down for more than a few hours in any 24, inconsequential

Like this you mean ?

My guess is that to make Harry's theory remotely plausible, it would need direct sunlight on the wall for a lot longer than that. Never going to happen.

Meanwhile, back in the real world....

So no justification for solar panels, in the U.K. ?

How much electricity do solar panels produce?

How much electricity do solar panels produce? Solar panels generate electricity during the day. They generate more electricity when the sun shines directly on the solar panels. Figure 1 shows PV generation in watts for a solar PV system on 11 July 2020, when it was sunny throughout the day and...

I would expect this research to be relevant

"to some extent".

Correct. I think MBK forgets that the Earth revolves or the sun goes in or that there are trees and acute angles.

And there we have it ,

That is just another stupid gotcha question.

 

[noseall]

So yes, absolutely - you would need to wait quite some time, but you do get that, eventually, if the temperature stayed higher outside than inside, some, likely quite small, small temperature rise on that wall will happen...
...and it wouldn't need to be that large a wall temp change to start to have a small on effect the temperature of the room - even at a 1 degree rise, that's one hell of a large radiator!

Correct. the energy of the sun is immense.

 

[noseall]

I think you're overstating your case here.

Whilst extreme or/and long enough heat (or cold) will (of course) change the indoor temperature, doesn't your own experience make it absolutely clear that, under UK conditions, insulation in practice generally prevents temperature matching - it might get warmer (or cooler) inside after a few days, but it is not inevitable that it will match the outdoors.

Precisely what I have been saying. The warmth of the sun ever penetration a well insulated wall in the course of the day = nil.

 

[Harry Bloomfield]

Correct. the energy of the sun is immense.

Seen some sense, at last perhaps!

 

[Harry Bloomfield]

Ah now I think I understand the 'inevitable' misunderstanding.

The heat flow from outside to inside starts as soon as there's a temperature difference.
