Hi Solitair, sounds good. I got 130 Watt and cost £500 so £190 for 60 Watt sounds a bargain.
Yes you can link them together much the same as you do with a Battery, although the panel should have a connecter box on the back, mine has two connecter blocks, one is to control panel and one is incoming from another panel.
At that price I would go for it.
I was advised that it should be a min of 50 Watt solar to 100 Watt battery per adult person. I went for the 130 sollar and 200 Watt Battery, even though I am a single camper.

Good luck
