If you have a good quality solar regulator, the size of the solar panels is irrelevant.

A good solar regulator will keep your batteries in good nick because once the batteries are fully charged, the regulator will only apply a FLOAT charge, which will maintain the batteries in a fully charged state without over charging them.
