To do their job, fridges and freezers need to be powered on constantly. If you have an unreliable power source, or you're in a remote location, you're going to have issues if you have food that need to be kept cool. Industrial Insulation Systems has a solution, which is basically a solar-powered refrigerator kit.
Using the sun's energy, the solar panel charges an internal battery. Additionally, due to the size of the solar panel, it also provides some shade for the refrigerator. The refrigerator/freezer is able to maintain temperatures down to minus 20 degrees Celsius, which is what's needed for 99.9% of food typically stored in a fridge or freezer.
A full charge of the batteries gives 24 hours continual chilling time, thanks to a bank of four 12V 100Ah batteries. The batteries are mounted out of the way at the base of the fridge. The solar panel itself is mounted on the frame of the refrigerator, keeping the unit compact and easy to move.
Unfortunately no pricing information is available on the website. A great idea though, and very suitable for remote locations, disaster relief, boats, humanitarian aid and domestic home use.
