The good news about solar: installation is mechanics, not electricity. Four well-placed screws beat a long speech β but a few rules save you drilling twice.
SWL-12 wall lights: 2β2.5 m β the height that lights a face without dazzling. SFL-01/ELS-08 flood lights: 3β6 m depending on area. Street lights: 4β5 m (DP-40), 6β7 m (DP-60), 8β10 m (DP-100). Higher = more area covered, but less intensity on the ground.
All ELS-DP heads clamp onto standard steel tube of 60β76 mm diameter β the tube every buildersβ merchant and metal workshop stocks. Concrete footing 60β80 cm for a 6 m pole; in windy spots, take the upper range.
Flood lights and ELS-DP heads also wall-mount: on a barn gable or workshop facade you save the pole, the footing and a dayβs work. Just check the panel faces south.
On SHL and SFL kits the panel mounts independently: due south, tilted 30β60Β°, clear of midday AND winter shadows. The 5 m of cable give you freedom β use it for the sun, not for convenience.
Drill, level, spanner, stepladder β and for a pole, a rented mini-digger or two hours with a pick. No 230 V work, therefore no electrician: your weekend or your works team handles it.
