Not a particularly good deal in my view. The controller seems to be inefficient, old technology and the whole "kit" is quite expensive for what it is.
Look here for advice on panels and controllers: https://www.motorhomefacts.com/ftopict-139267-.html
Edit: Sorry, the above gives info. on controllers. Her is a link to the panels I bought on the advice of Techno on here: http://www.ebay.co.uk/itm/100W-Solar...E:L:OC:GB:3160
I am highly impressed with the output from my system. It is 3 x 100w panels and the controller mentioned in the other thread.
