Battery or solar outdoor security light

Updated: 20.10.2026

The solar light over the side gate has gone dim again, and it is only November. The wall faces north, or a tree covers it by mid-afternoon, and another panel on the same bricks will see the same weak sun. Battery or solar outdoor security light is that fork. If the panel cannot see winter sun, buy a battery light you can charge or reload, and do not buy a second panel for the same wall. This page does not rank the eight battery models. Those rows, with prices from 19 October 2026, are on the [motion sensor outdoor battery comparison](/hub/burglar-protection/motion-sensor-outdoor-battery).

What fails when the wall is in shade

A solar security light works when the panel gets hours of direct sun. Green Gaffer’s notes put solar on a wall that sees that sun, and a battery light on a north or east wall, or under trees. A north elevation charges for a short window, then faces a long night. A tree does the same job. Blaming the PIR is the usual mistake. The sensor can be fine while the cell is empty. A panel on a lead still needs a south aspect. If the wall cannot offer that, the lead does not fix the season.

What a battery light still asks of you

A battery PIR does not need the sun. It still needs a cell you can reach. Auraglow takes three AA cells at £11.99. Each NICREW head takes four D-cells, not in the box, and reviewers say a set can cost as much as a cheap lamp. That is the cost beside the idea that solar is free. LaiTeny and ONEWAY are 10,000 mAh packs you charge indoors. AIXPI is 6,000 mAh. “Up to 120 days” assumes infrequent triggers. It is not a measured British winter. Constant-on overnight flattens a pack the way it flattens a small solar cell.

When solar is still the simpler light

Solar remains the simpler light when the panel has a clear south aspect and the job is a short burst. A gate that sees sun for several hours, including in winter, can keep a modest solar PIR alive. That purchase sits outside this comparison. It works where the sun reaches the panel. It fails on the shaded and north-facing walls where many side returns and sheds are. A head in the rain still needs a stated weather code, solar or battery. Leaving either on all night can annoy a neighbour. GOV.UK guidance on light pollution covers domestic security lights either way.

A recommendation with a condition

Choose a battery light when the wall is shaded, north-facing, or under trees. Choose solar only when you can point a panel at real winter sun. If the lamp you own already fails in November, replace the approach, not the identical panel. IP65 packs here are LaiTeny, AIXPI, and ONEWAY, with short review files. IP44 Auraglow suits a porch. NICREW suits a sheltered path if you will buy D-cells. A mix is reasonable: solar on the sunny front, battery on the shaded return. Who should skip each row is on the best battery powered outdoor motion sensor light page.

Common questions

Will solar work on a north wall in Britain?
It is the weak case. A north wall gets little direct winter sun, and a security light that depends on a panel will fade as the nights get longer. Green Gaffer’s buyer notes point battery lights at north and east walls and at spots under trees. A south-facing wall with an open aspect is the solar case. If your November failure is on the north side, another panel there repeats the problem.
Do battery lights still need the sun?
No. AA cells, D-cells, and USB packs in this set charge or reload without a panel. You still service them. D-cells are a shop cost. A 6,000 or 10,000 mAh pack needs a USB charge you can reach with a ladder you will climb. “Up to 120 days” on the ONEWAY listing is the seller’s claim for infrequent sensor use, not a measured result.
Which costs more over a year, D-cells or a rechargeable pack?
This page cannot give you a kilowatt-hour sum, because the listings do not state how often you will trigger the lamp. What they do show is the shelf price and the cell habit. NICREW’s four D-cells per head are extra, and reviewers say a set can cost as much as a cheap lamp. LaiTeny at £28.99 and AIXPI at £29.99 cost more on day one and then ask for indoor charging. Solar’s “free” line fails when the panel does not charge.
Can you mix one solar light and one battery light?
Yes, if each wall earns its own power source. Solar on a south-facing gate and a battery PIR on a shaded side return is a coherent pair. Two solar heads on the same north wall are not. Aim both so they do not wash a neighbour’s windows. The battery half of that pair is the table on the main comparison. The solar half is a different product type and is not ranked here.
What if the solar light already fails in November?
Treat November as the test the listing did not give you. If the panel faces north, east, or into trees, the season has confirmed the site. Move the panel to a south aspect if the lead allows it and the new spot really gets sun. If it does not, switch that wall to a battery PIR you can charge or reload. Buying the same solar model again does not add daylight.
