Sustainable Home Design Is it better to store solar energy into ice or hot water?

Question by mark m: Is it better to store solar energy into ice or hot water?
I’m usually gone most of the day at work. when i come home, the only two appliances that are on, is the AC and refrigerator. since their is no grid where i live, would it be more efficient to have the solar panels creating ice or hot water, while the sun is blazing during the middle of the day, and then us the ice and hot water to condition my home when i get back at night? or would buying and replacing batteries ever few years be more efficient, environmental friendly, and sustainable?

Best answer:

Answer by Matthew B
There are commercial system to create ice at off peak tariff times at night for use during the day. This ice can be used for multiple building via refrigerated pipes. Tri-generation with solar thermal could work on some environments.

Some advanced refrigerator controller built with solar in mind, run more during sunlight hours and less at night. This reduces the load from battery power.
