I want to put some LED lights on my sliding gate. I wondered if I
could power them inductively, with a power 'transmitter' fixed to the
gatepost and a power 'receiver' on the gate, positioned so when the
gate's shut they are close together and the LEDs come on. The power
requirement of the lights is 24W at 12VDC. The positional accuracy of
the gate is good.

What about solar?

See BigClive's solution. Needs water proofing though.

I started off wondering about solar but for a 12/12 hour duty cycle the
requirement would be about 0.3kWh per day. Unfortunately the gate area
doesn't get much sun. The back of the gate does face south but trees and
buildings screen it most of the time in winter.

You would need a 8kW solar array, and probably 1.5kWh of storage to make
that a reliable year round proposition. So not practical on any level.
