I have a couple and have serviced several for other people. They all

Fairy Nuff, I was going from memory of reading the rating plates... Still
5.5A @ 14v is still the best part of 80W and bear in mind that 120W panel
will only do that in bright, full, sunshine... You'll probably still need
one that size to ensure that you have enough power when it's not full
bright sushine. And what about night time...
