Frequently asked questions
What is the best spacing for solar path lights?
Around 1.5-2.5m between lights usually gives even, overlapping pools of light without looking cluttered or leaving dark gaps. Wider spacing works for decorative accent lighting, while tighter spacing suits paths that need to be clearly walkable after dark.
Why do solar lights need direct sunlight to work well?
Solar lights charge a small internal battery through their panel during daylight hours, so a spot that gets several hours of direct sun each day will give a brighter, longer-lasting light through the night than one that's shaded by fences, hedges or overhangs.
Do solar lights work well through a UK winter?
Shorter daylight hours and overcast skies mean solar lights generally give less runtime in winter than summer. Lights with larger panels and batteries cope better, and keeping the panel clean and free of frost or leaves helps maximise charging.
Should I line both sides of a path or just one?
Lighting both sides gives a more even, symmetrical look and better lights the full width of the path, but costs roughly double. A single side staggered at a slightly tighter spacing is a reasonable lower-cost alternative for narrower paths.
