Quick answer: for weekend use, a 1kWh portable power station plus around 200W of solar panels will run lights, phones, a laptop and a 12V fridge in summer. For frequent stays or a holiday let, step up to a 2kWh power station and around 400W of panels. For living in a shepherd’s hut full-time, you’ll want a fixed system from a qualified installer, or a mains supply if one is within reach.
Heat with a wood burner, not electricity. No battery system you can carry will run an electric heater for long.
What uses power in a shepherd’s hut?
Most huts need surprisingly little electricity, as long as heating and cooking aren’t electric. Here’s a typical day:
| What | Typical use | Energy per day |
|---|---|---|
| LED lights | 15W for 5 hours | 75Wh |
| Phones | 2 charges | 30Wh |
| Laptop or tablet | 60W for 3 hours | 180Wh |
| 12V compressor fridge | Runs on and off all day | 240 to 600Wh |
| Water pump | Short bursts | About 20Wh |
| Total | About 550 to 900Wh |
The fridge is the big variable. A 40 to 45-litre 12V compressor fridge typically uses 240 to 600Wh a day, using less in cool weather and more in hot weather (source). Skip the fridge in winter, or use a cool box in the shade, and your daily use roughly halves.
Three setups, from weekends to full-time
1. Weekend hut: about 1kWh plus 200W of solar
Enough for two or three days of lights, phones and a laptop, plus a fridge in mild weather. Charge it at home before you go, and let a 200W panel top it up during the day.
- Power station: a 1kWh unit such as the EcoFlow DELTA 3 Plus or Bluetti Elite 100 V2
- Solar: around 200W, such as the EcoFlow 220W Bifacial or Bluetti 200W
- Rough cost: about £750 to £1,050 for the pair
Prices are approximate UK prices (RRP or typical retailer price) when we checked in November 2026. They change often, so use the buttons to see today’s price.
2. Regular stays or a holiday let: about 2kWh plus 400W of solar
Guests expect the sockets to work, so build in headroom. A 2kWh unit covers a full day with a fridge running, and around 400W of panels can refill it on a good summer day.
- Power station: a 2kWh unit such as the EcoFlow DELTA 3 Max (2,048Wh) or Bluetti Elite 200 V2 (2,073.6Wh)
- Solar: two 200W panels, or similar
- Rough cost: about £1,800 to £2,150
3. Living in it full-time: a fixed system or mains
For year-round living, a portable setup will struggle in winter. Options:
- A fixed off-grid system: roof-mounted panels, a larger battery bank and an inverter, designed and fitted by a qualified installer
- A mains supply: if the hut is near a building with electricity, an electrician can run a proper supply, as you would for a garden office. This is notifiable work in England and Wales.
How much will solar really give you?
Solar in the UK swings hugely with the seasons. Based on UK solar data, roughly:
- 200W of panels: about 0.8 to 1.1kWh a day in summer, but only 0.1 to 0.25kWh in winter
- 400W of panels: about 1.6 to 2.2kWh a day in summer, and 0.2 to 0.5kWh in winter
(source)
In practice, that means solar can keep a hut going through the summer, but in winter you’ll need to charge the power station at home, from your car, or cut back what you use.
Heating and cooking: keep them off the battery
- Heating: a small wood burner is the classic shepherd’s hut choice, and it uses no electricity. Have it installed properly with a flue, and fit a carbon monoxide alarm.
- Cooking: a kettle or hob on electricity would drain a battery in minutes. Most UK kettles draw 2,500 to 3,000W, more than most portable power stations can supply. Gas is the usual choice, fitted safely with ventilation.
Practical tips
- Use LED lighting throughout. It’s the easiest saving there is.
- Choose a 12V compressor fridge, not an absorption or mains fridge. They’re far more efficient off-grid.
- Angle your panels towards the sun and move them during the day if you can.
- Don’t charge lithium batteries below freezing. Check your power station’s temperature range, and bring it indoors on frosty nights.
- Keep a car charging cable, so you can top up on the drive in winter.
Frequently asked questions
Can a shepherd’s hut be completely off-grid?
Yes, for weekends and summer use it’s easy with a portable power station and solar. Year-round living off-grid needs a bigger, fixed system and careful winter planning.
What size power station do I need for a shepherd’s hut?
Around 1kWh for weekends without much fridge use, and around 2kWh if you run a fridge or let the hut to guests.
Can I run an electric heater from a power station?
Not practically. A 2kW heater would empty a 2kWh power station in about 50 minutes. Use a wood burner instead.
Will solar panels work on a shepherd’s hut in winter?
They’ll still produce some power, but only a fraction of summer output. Plan to top up from the mains or a car.
