It's a fair price, but not a screaming deal.
it's four of these, on Amazon for $225 USD or 140 GBP:

Off the shelf this is 638 GBP, plus they are putting it together and throwing in some wires for another 85 pounds. It's not a terrible deal but you can likely save a few quid if you do it yourself.
Also, you will probably need to consider a battery bank and an inverter in your system cost as well. Depending on your chosen voltage and run lengths, this is also where you might also need to spend several dozen pounds on wiring.
However, you can run this as a 48v system (you would need a different controller) and that would keep wire sizes down.

If you're not planning on using the alternator to charge the battery, I doubt that 60w alone is enough to run a fridge. I have a 115w panel that I use to run a small dometic fridge and it works well if it's sunny. I could probably get away with less, but I doubt half as much, which is what you have. On the other hand, if you're only going to run it for a weekend, get the largest AGM battery you can fit in the space you have and recharge it when you get home.
Get an MPPT charge controller because you want to maximize the output from those small panels.
Here are the fridge and charge controller I have and am happy with.
