Reliable Solar Solutions for Every Adventure
A 4WD solar panel keeps your gear running wherever you go. It turns sunlight into solar power for fridges, lights, and devices. These solar panels are designed for Australian conditions. They give you clean and quiet energy for the bush, the beach, or your next off-grid trip.
Choose a setup that suits your style. Folding and portable panels are easy to move and pack away. Fixed panels fit neatly on the roof of your vehicle, caravan, or campervan. Each model uses strong aluminium frames and high-efficiency monocrystalline cells for steady power every day. They work with lithium, AGM, and lead-acid batteries, so your system stays reliable.
Shop at Outback Equipment for trusted brands like Hardkorr, Tuff Terrain, Enerdrive, Companion, Baintech, and more. Build a simple off-grid setup for your 4WD, caravan, or camper.

Frequently Asked Questions About 4WD Solar Panels and Camping Solar Solutions
How to Calculate 12V Solar Panel Requirements
To calculate your solar panel requirements, first determine your total daily energy use. Add up the wattage of all your 12V appliances and multiply by the hours they run each day. This gives you watt-hours (Wh), which show how much power you need to replace daily. Compare this total with what your panel can produce. For example, if a 100W solar panel receives five hours of full sunlight, it generates about 500Wh per day.
Here’s a sample calculation for a typical 4WD or camping setup:
- LED Lights: 10W × 5 hrs = 50Wh
- Small Refrigerator: 60W × 10 hrs = 600Wh
- Fan: 20W × 5 hrs = 100Wh
- Phone Charging: 5W × 2 hrs = 10Wh
Total: 760Wh per day
If your 12V solar panel produces 100W per hour and gets 5 hours of direct sun (100 × 5 = 500Wh), you would need two 100W panels to meet your 760Wh daily requirement efficiently. Always add about 20% extra capacity to allow for cloudy conditions or shade.
Can I connect a 4WD solar panel directly to a battery?
No. Always use a solar regulator or MPPT controller between your panel and battery. It regulates voltage to prevent overcharging, ensuring safe and efficient charging for lithium or AGM batteries.
Do 4WD solar panels still work in cloudy or shaded conditions?
Yes, but their efficiency drops. Monocrystalline panels still generate power in partial sunlight, though charging will be slower. This can be enough to maintain your battery level for lighting and small accessories.
Can I use these solar panels on caravans and campervans?
Yes. The same 12V solar panels for 4WDs can power caravans, campervans, and RVs. Just match your total wattage to your energy needs and ensure your battery bank is large enough for your setup.
