Solar Systems for Australian Caravans and Campers
Australia’s solar resource is among the best in the world, making solar power the natural choice for off-grid camping. A well-designed solar system provides reliable, silent power that keeps your fridge cold, devices charged and fans running indefinitely.
Calculating Your Power Needs
Before buying any solar equipment, calculate your daily power consumption. A typical two-person caravan uses 50-70Ah per day without air conditioning. A 300W solar panel in good Australian conditions generates 80-120Ah per day. Match your system to your needs with a 20-30% margin for cloudy days.
Panel Types
Rigid monocrystalline panels offer the best performance per dollar for fixed roof installations. Flexible panels suit curved surfaces but degrade faster and run hotter. Portable folding panels offer maximum flexibility for those who move frequently or camp in shade.
Controllers
Always choose an MPPT (Maximum Power Point Tracking) solar controller over PWM. MPPT controllers extract 20-30% more power from your panels, especially on partially cloudy days. Victron, Redarc and Renogy all make excellent MPPT controllers for the Australian market.
