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?
If you're away from the grid, I think it would be expensive to expect to heat and cool your home with solar alone. It could be done, but just very expensive.
I don't know the details of your place, but it would likely be more efficient to super-insulate the house, or even build it below ground. I visited a house in Wyoming when it was 110 F outside, and it was a pleasant 80 degrees inside in the afternoon. They had foot-thick insulation, and a fan to bring in cool air at night.
Certainly, don't use electric panels to create hot water. Use solar thermal panels designed especially for heating water. That will be 6-10 times more efficient. Then store the water in a big tank.
But to answer directly, unless your refrigerator vents to the outside, it only redistributes the heat in the house. It takes the heat out of water, making ice, and puts that heat into the air. Ultimately, if you were to take the ice out and use it for cooling, it would not compensate for the heat put into the air. An air conditioner take the heat from the house, and pumps it outside.
Is there any possibility of cooling your house with deep well ground water?
