Wondering what the secret is to caravanning off-grid for extended periods? The answer lies in high-quality, efficient solar power. In Australia, where the sun is a generous companion no matter the time of year, off-grid goers tend to ask the question: what is the most efficient 12-volt solar panel to install on my caravan or 4x4?
Among the myriad of options available, the best 12V solar panels stand out as the backbone of any off-grid adventure. Let's dive into the details of Australia's best 12-volt solar panels and find a panel that suits your needs.
12V solar panels should be measured against the following metrics:
Power Output
The power output of a solar panel determines how quickly it can charge your batteries or power your devices, and is measured in watts. Higher power output means faster charging, which is pretty much always going to be a good thing. The power output of the panel should match or exceed your energy requirements.
If you plan to power multiple devices or appliances, you'll need a solar panel with a higher power output to ensure it can meet your needs reliably.
Efficiency Rating
A 12V solar panel's efficiency rating indicates how effectively a solar panel converts sunlight into electricity. A high-efficiency rating means the solar panel can generate more electricity from the same amount of sunlight.
Cell Type
Different cell types have varying performance characteristics, especially in challenging conditions such as low light, shading, or high temperatures. For example, monocrystalline solar panels typically perform better than polycrystalline or thin-film panels in low-light conditions, making monocrystalline solar panels more suitable for camping or caravanning where sunlight may be partially obstructed for periods of the day.
Size and Weight
It is important to select 12V solar panels that suit your specific portability requirements. Caravanners and campers typically opt for either roof-mounted, fixed solar panels or lightweight folding solar panels that can be carried and moved around a campsite.
Features
When selecting a 12V solar panel for your caravan or camping vehicle, consider additional features such as warranty and support offerings, regulator/solar charge controller compatibility, mounting options, weather resistance, and durability.
Based on these factors, here are the six best 12V solar panels for Australian caravanning and camping:
