I'm looking at solar powered pir outdoor leds.

Let me guess, they are off! ;-)

Does the solar panel
have to face the sun or is sky view sufficient. ( Id need to make up
a bracket to allow the panel face south)

Just position them near a bright halogen, and they will be fine.

Yup, pointing toward the sun will help a bit, but they are generally
unsuited to UK winter operation IME.

I have one of the PIR devices powered by 3x C cells over my front door.
Been going nearly two years now on the same batteries. I fitted one
outside the VH. I bring the solar PV garden lamps in for the winter.

The dank foggy weather and winter frosts destroys their batteries. We
have plenty of solar powered "Please go round the (dangerous) bend"
signs round here. They are great fun in mid-summer flashing away and for
an hour after sunset in winter but completely dead in the water on a
cold frosty winters morning when they might actually do some good.
