Best Portable Solar Panel UK 2026: Folding Panels and 12V Kits for Power Stations, Caravans and Sheds

Portable Panel or Fixed 12V Kit?

These are two different jobs, and buying the wrong type is the most common mistake.

• A folding portable panel charges a portable power station (EcoFlow, Jackery, Anker, BLUETTI) or a phone directly. The power station holds the battery, the charge controller and the sockets, so the panel is the only extra you need. You put it out when the sun's up and pack it away after. This is the camping, festival and power-cut route.
• A fixed 12V kit is a rigid glass panel plus a charge controller that you mount permanently on a shed, caravan, boat or van and wire to a 12V leisure battery. It's cheaper per watt and works unattended, but you supply the battery, and you need a 12V-to-230V inverter if you want ordinary three-pin plugs.

Rule of thumb: if you already own a power station, buy a folding panel. If you're building something permanent with a 12V battery, buy a kit. If you own neither and only want lights in the shed, skip both and buy the all-in-one lighting kit.

How Much Power You'll Actually Get

The number on the panel is its output in lab conditions: full sun hitting it square on, with the cells at 25C. A British day almost never looks like that, so judge a panel by watt-hours per day for where you live and when you'll use it. The figures below come from PVGIS, the European Commission's solar model, for a panel fixed at 40 degrees facing due south. Pick your panel, region and month:

Three things jump out once you play with it.

• Winter is roughly a third of summer. In Birmingham a 100W panel averages about 380Wh a day in June and 120Wh in December. In Inverness, December drops to about 50Wh. Short days and a low sun do that, not the cold (cold actually helps panels slightly).
• South beats north, but not by as much as you'd think. Plymouth to Edinburgh is a difference of about 16% over a year. Where you point the panel and whether it's in shade matters more.
• Angle matters for portable panels. A panel lying flat, or left facing where it was at 10am, loses a big chunk. Re-angle it towards the sun two or three times a day and you'll close a lot of the gap to the best-case figure.

Will It Work With My Power Station?

Two checks, and both are in your power station's manual.

1. Voltage. Every station has a solar input range (for example 12 to 60V). The panel's open-circuit voltage has to sit inside it. Go over it and the station may refuse to charge, or be damaged. The 400W Anker PS400 lists a maximum of 57.6V, which is more than some smaller stations accept. The Renogy 200W lists 21.6V, which nearly everything accepts. You can wire two identical panels in series to add their voltages, or in parallel to add their current, but check the station's limits first.

2. Connector. Most panels come with MC4 plugs. Stations use XT60 (EcoFlow and Anker both supply MC4 to XT60 cables), Anderson, a DC barrel socket or a brand-specific plug. An MC4 adaptor for your station costs a few pounds. The brand-matched panels (Jackery to Jackery, EcoFlow to EcoFlow) save you this step, and that convenience is most of what you're paying for.

And one sizing check: don't buy more panel than your station can take in. A station with a 200W solar input limit gets nothing extra from a 400W panel at midday. The extra watts do help on dull days and in the morning and evening, so a modest oversize (say 300W of panel on a 200W input) isn't wasted. Doubling it mostly is.

Building Your Own 12V Shed System

If you'd rather choose each part, a simple off-grid shed or garden office system is four pieces. Here's what we'd buy:

Two 100W panels, the Victron and the battery come to about £370 before cables, fuses and an inverter, which is a lot more than the ECO-WORTHY 240W kit at about £164. What you get for the difference is a battery (the kits don't include one) and a better controller. If you're on a budget, buy the kit, add the battery, and swap the controller for the Victron later.

Do fuse it. A lithium battery can deliver an enormous current into a short circuit. Put a fuse on the positive battery cable as close to the battery as you can, sized to the cable. If you aren't confident with DC wiring, have an electrician look over it before you leave it running unattended.

Winter and lithium batteries. LiFePO4 batteries shouldn't be charged when the cells are very cold. Both the ECO-WORTHY and most decent rivals stop charging automatically when the cells drop below a set temperature (ECO-WORTHY lists -7C). An unheated shed in a cold snap can get there, so expect solar charging to pause on the coldest mornings.

Is It Worth It for the Money?

Not on electricity savings alone, and it's worth being straight about that. On PVGIS figures a 200W panel in the Midlands makes about 195kWh a year best case, closer to 145kWh in real portable use. At the current price cap of 26.32p/kWh that electricity is worth roughly £38 to £51 a year, and only if you'd otherwise have bought every unit of it from the grid.

Where these panels pay their way is in what they make possible: lights and a laptop in a garden office with no cable run from the house, a caravan that doesn't need a hook-up, or a power station that stays topped up through a two-day power cut. Buy for that, not for the bill.

If you want to cut your actual bills with solar, the maths is completely different with a roof system. A typical 4kWp system makes around 3,800kWh a year in central England, worth about £700 a year on our model. Our solar panel costs guide runs the numbers.

Can I Plug a Solar Panel Into a Socket?

Not these ones. Since 27 August 2026, plug-in solar (sometimes called balcony solar) that feeds a normal household socket has been lawful in Great Britain, though not in Northern Ireland. It needs kit built for that route, and battery-integrated kits are excluded. A portable panel or a 12V kit is a completely separate thing: it charges a battery that you then use off-grid, and it should never be wired into your home's mains. Our plug-in solar guide explains what's allowed and what's worth buying.

Do I Need Planning Permission?

For a folding panel you put out on the grass and bring back in, no: it isn't an installation. For panels fixed to a shed, garage or garden office in England, the Planning Portal says solar on a house or on a building within its grounds may be permitted development, so no application is needed, as long as the limits and conditions are met. Check those with your council if you're unsure, especially if you live in a listed building. Wales, Scotland and Northern Ireland run their own planning systems.

What We'd Skip

• No-name "300W" folding panels at £100 or less. Some of these list efficiency figures and wattages that their size can't physically deliver, and they have tiny review counts. If a panel claims far more watts than a Renogy or Anker panel of the same size, believe the size.
• Brand-matched panels you don't need. A £349 EcoFlow 220W on a station that already has an XT60 input does the same job as a £170 Renogy plus a £5 adaptor. Pay for the brand only if the convenience is worth that much to you.
• Panels bigger than your station's solar input. Check the input wattage before you buy. A 400W panel on a 200W input station is mostly wasted money.
• Lead-acid leisure batteries for new builds. They're cheaper up front, but heavy, and LiFePO4 now costs little enough that we'd go lithium for a new shed or van system.
• Battery-integrated "plug-in" kits sold as if they can feed your home sockets. Battery-integrated kits are outside the GB plug-in solar route.
