You need better solar panels than you want to spend the money on to get a decent charge in the UK. Far cheaper to look at how many charges you think you need, add them up and look for a battery that roughly matches that.
Just get a bigger battery, not from Amazon if you can help it, but this is well rated, WAY bigger than you picked and rather better priced:
