Solar Fence Lights: A UK Buying Guide

The best solar fence light for your garden depends mostly on which way the fence faces. A south-facing fence suits a light with a built-in panel. However, for a shaded or north-facing fence, choose a light with a separate panel on a lead, and place the panel in the sun.

This guide covers the main types and the sunlight sums for each direction. It also covers the fixing and neighbour points that UK gardeners often miss, because they cause real problems. We choose from published specifications and have not tested these lights, as our page on how we choose explains.

What types of solar fence lights are there?

Most solar fence lights fall into three groups. Each suits a different fence, so the right choice depends on the job.

• Post-cap lights: these sit on top of a fence post. They give a gentle glow along a boundary, and the panel faces the sky.
• Fence or wall lights: these screw to the face of a fence. The panel is usually part of the light, so it points the way the fence faces.
• Spotlights with a separate panel: you fix the light where you want it and the panel where the sun is.

Our solar garden lights guide lists wall and fence lights as the pick for paths and doorways. It also notes the drawback. The panel is fixed to the light’s position, so output drops if the spot is shaded. That is why direction matters so much.

Which way does your fence face?

Direction matters more than any other choice. A fence is a vertical surface, so it sees the low winter sun differently from a panel tilted at the sky. PVGIS, the European Commission’s solar tool, gives the daily sunlight on a vertical surface in London.

Now do the arithmetic. In December, a north-facing fence gets 0.19 ÷ 1.61, or about 12% of what a south-facing fence gets. An east-facing fence gets 0.47 ÷ 1.61, or about 29%. For Edinburgh, the same method gives 0.11 for north and 1.09 for south in December.

In June the gap closes, because the sun is high and rises in the north-east. East and west fences even beat south ones. However, you want light all year, and winter is the hard test. A north-facing fence with a built-in panel will struggle through the winter months.

PVGIS includes terrain shading only, because it does not know about your house, your trees or the fence panels themselves. So real figures can be lower than these.

Built-in panel or separate panel?

Choose by direction. On a south-facing fence with no shade, a built-in panel works well and keeps fitting simple. On a north-facing or shaded fence, however, a built-in panel will gather very little.

A separate panel solves that problem. The light sits on the shaded fence, while the panel sits on a sunny post, shed or south-facing fence. For example, a panel on a lead can catch sun that the light never sees.

Also tilt the panel steeply in winter if you can, because the sun stays low. For example, PVGIS gives London 0.67kWh per square metre per day in December for a flat surface, against 1.64 for a surface tilted at 60 degrees towards the south. That is about 2.4 times as much (1.64 ÷ 0.67).

What IP rating do fence lights need?

A fence stays outdoors all year, so choose a proper weather rating. We suggest IP65 or better on exposed lights, as our guide to IP ratings for waterproof solar garden lights explains. IP65 means dust-tight and protected against water jets.

Check the full code on the product page, because the word “waterproof” alone tells you nothing.

How bright and what colour?

Look for lumens, not the number of LEDs. ENERGY STAR advises shoppers to look for lumens, because lumens measure light output. The LED count alone does not tell you how much light a fitting gives.

For colour, warm white suits most fences, since it looks softer. ENERGY STAR places soft and warm white at around 3000K and below. Higher numbers look cooler and bluer.

What about your neighbours?

Most fences are shared boundaries, so think before you fix anything. GOV.UK says that in England and Wales there is usually no record of who owns the fence between two properties. Therefore ask your neighbour before you drill into a shared fence.

Brightness matters too. GOV.UK says councils must look into complaints about artificial light from premises that could be a statutory nuisance. It sets no fixed light levels. In practice, aim lights down and into your own garden. Also choose a dimmer or motion-sensor mode if the light faces a bedroom window.

How do fence lights compare with other styles?

Fence lights give fixed, tidy light. However, if you want a softer festive look along a fence top, read our guide to solar string lights. Check that a string has a lead, so you can position the panel freely.

Lights need only small amounts of energy, while a shed or garden office needs far more. For that, see our guide to what size portable power station you need. If you also want to charge a phone on the plot, compare a solar power bank with a folding solar panel.

Frequently asked questions

Do solar fence lights work on a north-facing fence?

They work poorly with a built-in panel, especially in winter. For example, on a north-facing vertical surface in London, PVGIS gives 0.19kWh per square metre per day in December. So a separate panel in a sunnier spot is the better fix.

Do solar fence lights need direct sunlight?

They charge best in direct sun. However, the PVGIS averages above cover 2005 to 2023, so they already include typical British cloud. Expect shorter runs when the sky is dull.

Where can I find more on garden lighting and power?

Our hub on solar garden lighting lists every guide, while the other hubs cover wider needs. For bigger loads, see solar generators and power stations and the power station buyer’s guide. For outdoor phone charging, see portable solar chargers. To see where indoor power goes, try home energy monitors.
