The OP said solar powered ideally, which means mains is available.
You could supplement the solar - or replace it if running on PIR
only - with a small mains 12-15v PSU sending charge current down a
long thin wire.

Under the worse conditions - mid winter - the batteries will be on
charge for a shorter period than the lights are running.

Ah, the OP has emailed you more about their use I see. I thought they
might be running them on PIR mainly.

If you read the post, he says 'Auto day light switching and solar powered
ideally'

PIRs usually have that
