I'm sure this has been brought up plenty of times here,

You would need a larger panel and a battery
At least 150 watts and a mar

So youre saying the tech is still too far behind for there to be any practicality at the moment?

>>976287
Yes.
Right now it takes a $1000 arb fridge or equivalent and 150 watts solar and a car battery.

Wood burning coolers are where it's at.

I do diy a lot for various things. A solar cooler would be pretty easy to make. You don't even need moving parts to make one. Just big heat sinks, sizeable solar panel, some wiring, and some Peltier coolers. You'd be making a solar powered, thermoelectric cooler. Just retrofit it into a cheap second hand cooler. You don't even need to solder anything, just use butt-end connectors. If you want to add a battery the costs increase and you'd need a solar charge controller for them.

The biggest thing will be the solar panel itself. A general purpose Peltier cooler panel will need 86 to 96 watts. They are pretty tiny too. Without a battery, you'll need a 100watt solar panel. Check the pricing on those. Pretty high costs unless you buy cheap ebay stuff and solder them up into a panel.

The only good thing about such a system is that there are no moving parts, so nothing wears out very quickly. The down side is that cooling will be very slow since there's only 1 Peltier cooler under 100watts. Thus, the better a cooler you use the more efficient the system can be.

I think you can make a solid solar powered cooler for as little as $200. That's a prebuilt 100watt solar panel and all the rest of the stuff listed above. Maybe $175 if you get ebay PV seconds. For every extra Peltier cooler you add, you need another solar panel. Batteries would up the cost quite a bit, but will extend the use quite a bit too.

I have a few TEC1-12706 Peltier coolers and I do all sorts of stuff like this with them just for experimenting. I even made a thing to hook them to my exercise bike electric generator to make water from the air (horribly inefficient, but worked when the dew point was high enough; would be better on a regenerative breaking system on a real bike).
