WHAT SIZE SOLAR PANEL & BATTERY DO I NEED?

FOLLOW OUR GUIDE BELOW TO PLAN YOUR SOLAR PANEL AND BATTERY UPGRADE.

For the most accurate Amp Hour (Ah) data, refer to the manufacturer’s specifications.

For example, the Dometic NRX115 fridge freezer consumes an average of 1.27Ah when set to +5°C at 25°C ambient temperature.

You can easily calculate the Ah by dividing the average wattage of the appliance by its voltage to obtain the amps per hour.

Average Watts Per Hour System Voltage Average Amp Draw Per Hour (Ah)
12V

Determine the number of hours each appliance will run per day, and input this data into the solar calculator below accordingly.

Our solar panel calculator provides average sunlight hour data for each location across the year. Keep in mind that summers typically offer more sunlight hours compared to winters.

Utilise the calculator to experiment with different solar panel sizes and configurations that align with your requirements.

The calculator below will tell you how long you can travel off-grid if solar is not available

Autonomy (it's raining/no sun):

*Based on industry standard

**You will be able to camp off-grid indefinitely provided there is sufficient sunshine

Note:

  • Solar power calculator assumes 12V solar panels are connected in parallel.
  • Please note, Amp Hour (Ah) in this calculator have been rounded to the nearest whole number.
