Solar power lets you camp longer away from powered sites, keeping a portable fridge cold, lights on and phones charged. With so many panels, batteries and kits available, it helps to understand the basics first. This camping solar panel guide explains how solar setups work, how to size one and how to get the most from the sun.
How a camping solar setup works
A typical off-grid setup has four parts:
| Part | What it does |
|---|---|
| Solar panel | Converts sunlight into electricity |
| Regulator (charge controller) | Controls charging so the battery isn't overcharged |
| Battery | Stores power for use at night and on cloudy days |
| Outlets and accessories | 12V sockets, USB ports or an inverter for 240V devices |
Some all-in-one portable power stations combine the battery, regulator and outlets in one unit, and you simply plug in a compatible panel.
Types of camping solar panels
| Type | Pros | Things to consider |
|---|---|---|
| Folding panel (briefcase style) | Easy to set up and angle toward the sun | Bulky to pack |
| Solar blanket | Light and compact, can drape over a windscreen | Usually costs more per watt |
| Fixed roof panel | Always charging while you drive or camp | Can't be moved to chase sun; needs installing |
| Small USB panels | Light, for phones and small devices | Limited output |
Folding panels
Folding panels are popular with campers because you can place them in the sun while parking your vehicle in the shade. Look for sturdy legs, a protective bag and a long enough cable.
Solar blankets
Solar blankets fold small and are light, making them handy for four-wheel drive trips where space is tight.
Fixed roof panels
Fixed panels on a caravan, camper trailer or vehicle roof charge whenever there's sun. Installation and wiring should be done by a qualified auto electrician.
How much solar do you need?
Work out how much power you use in a day, then size your panel and battery to match.
- List your devices: Fridge, lights, phone chargers, fans, a CPAP machine or water pump.
- Check their power draw in the manuals or on the labels.
- Estimate daily use in watt-hours or amp-hours.
- Allow for cloudy days and shorter winter daylight.
As a rough starting point, many campers running a portable fridge, lights and phone charging use a panel of somewhere around 120 to 200 watts with a suitable battery, but your actual needs vary with fridge size, weather and how long you stay. Check your appliance ratings before buying.
Batteries and power stations
- Lithium batteries are lighter and allow deeper use of their capacity, but cost more upfront.
- AGM (lead-acid) batteries are cheaper but heavier.
- Portable power stations are all-in-one units with built-in outlets.
Check that your regulator suits your battery type, and follow the manufacturer's instructions for charging.
Getting the most from your panels
- Face the sun: In Australia, panels generally face north.
- Adjust the angle through the day if you can.
- Avoid shade: Even partial shade can cut output significantly.
- Keep panels clean of dust, leaves and bird droppings.
- Keep cables short where possible to reduce power loss.
- Keep panels cool: Allow airflow behind them, as heat reduces efficiency.
Backup options
Solar is great, but on cloudy stretches you may want backup:
- Generators: A quiet inverter generator can top up batteries. Check campground rules first, as some don't allow them. See our generator buying guide.
- DC-DC charging: Charges your camping battery from the vehicle while driving.
- Power banks: Handy for phones, cameras and small devices. Read our power bank buying guide.

Saving power at camp
- Pre-cool your fridge at home before you leave.
- Keep the fridge in the shade with good ventilation.
- Use LED lights, which draw little power.
- Charge devices during the day while the sun is out.
- Turn off inverters when you're not using them, as they draw power on standby.
Safety tips
- Use cables and connectors rated for the current.
- Use fuses or circuit protection as the instructions require.
- Secure panels so they don't blow over in the wind.
- Keep connections dry and off the ground.
- Have permanent wiring done by a qualified auto electrician.
- Never run a generator inside a tent, caravan or annexe.
Before you go
Test your setup at home before your trip. Check cables, connectors and charging, and pack spare fuses. For everything else, see our camping checklist.

Frequently asked questions
What size solar panel do I need for a camping fridge?
Many campers use somewhere around 120 to 200 watts with a suitable battery, but it depends on your fridge, the weather and other devices. Check your fridge's power draw first.
Do I need a regulator?
Yes, a regulator (charge controller) protects your battery from overcharging. Some panels and power stations have one built in.
Will solar panels work on cloudy days?
They still produce some power, but much less. Plan for backup on long cloudy stretches.
Which way should camping solar panels face?
In Australia, panels generally work best facing north and angled toward the sun, with no shade.
