Do you run a fan as well? How often?
If so, bear in mind that the fan should draw as much if not more than the remaining stuff combined. Mine consumes ~140mAh.
Also, make sure the panels are fully exposed. Even seemingly small cast shadows reduce production a lot.
I am running a 85W panel with a 45Ah flooded battery (consumption includes a fan 24/24h and the RX unit as well) and so far the worst I got were 12,2V back in February.
Most of the time it drops down to a daily minimum of 12,5v (in Summer) and 12,4v in Winter (lower temperatures affect the battery outside).
But, we do have a fairly sunny climate Wink
