DIY solar air conditioner freezes 2.5MJ ice to deliver 700W off-grid cooling
SMRTR summary
A Florida resident built an off-grid air conditioning system using solar panels to freeze 2.5 gallons of water during the day, storing thermal energy that provides 700 watts of cooling power for several days. The system uses a glycol loop to extract cold from the ice block and circulate it through a radiator, delivering small air conditioner-level cooling entirely off-grid.
