A solar panel to keep the 12 V battery of an electric fencer charged. Pick the size to suit your fencer: Lacme's own advice for its fencers is 7.2 W for the Secur 130, 14 W for the Secur 200 and 33 W for the Secur 300 and iPulse 500.
Check whether your fencer already has a charge controller; if not, see the solar charge controller.
