Where's the cloudy-day heat store?

Thanks Nick, but what would a cloudy-day heat store achieve?
Extremely new to this....
I'm guessing with 10 cloudy days a winter this may not be an issue?

My original question stands....Can I realistically get much heat by
using this system?

About 32 ft^2 for the 408... 1804 Btu/ft^2 falls on a sloped surface
on an average 45.7 F December day.

It would keep the tub warm on a cloudy day. You might look into evac
tubes that store hot water inside, eg Sunda Seido-3s sold in Germany.

You may have more than that...

Sure, but most of it may be useless, if 103 is too cool and 105 is too hot.
