No and yes, no because the batteries in those things are too small. Basically the battery would be flat before the solar panel had a chance to keep it charged. You really need big batteries to keep a decent 12v fridge going. That booster thing has a 15ah battery, in my camper I have two 180ah batteries so you can imagine the weight compared to the booster thing. Or if you can't then its 50 kilos. You'd probably get away with a 180ah (25kilos) for the whole festival, but you'll also need a solar regulator as well in case of the panel overcharging the battery with disasterous result. So yes, but only if you do it properly, and only if its very sunny!

And, of course it would in fact be easier and cheaper to buy cold beer and bacon sandwiches...

Absolutely, a 60w solar panel £200, 12v fridge £250, 180ah battery £150, cables etc £15, regulator £25............

I used one of the Coleman Xtreme cool boxes this year for food. I made and froze lots of stuff like chilli / bolognaise etc etc in tubs, and kept "fidge" stuff like cheeze, butter and milk in it too. It was packed on Tuesday morning as we drove down and stayed in a B&B Tue night. The frozen stuff lasted fine, the last of it was de-frosted but still very, very cold by Sunday night, the butter stayed solid and the milk fresh for the duration!
Gotta be a cheaper and safer option than a fridge and worked perfectly well for us
