To continue what we were starting to discuss when the previous thread got killed...
What do you call using an ice machine (or running the compressor in a freezer hard to 'super-cool' it) during the peak sun times...then easing on the loads, to run all night on a more basic battery bank?
Your idea is very sound.
In effect, using ice cubes as your "battery."
On those ice makers, the power consumption seems almost too good to be true...but since they are super-cooling the little nipples to make cubes, it could be.
You could recycle the water actually, if it was strictly to cool and not drink.
Wonder what a cost-comparison would show on it??
How much actual time it would take??
It certainly is an interesting idea!
With a setup like mine, where I have "more panel than battery" it would be ideal for sure.
...so when are you ordering the icemaker??
