Solar energy is becoming an increasingly popular energy source for off-grid adventures. If you've ever wondered if you can run a fridge off solar or what size panel you will need for your other electronics - you're in the right place.

Welcome to the ultimate guide to using solar power to run your camping fridge and other essentials during outdoor adventures.

What is solar energy?

Solar energy is power harnessed from the sun’s rays. If you’ve ever experienced a scorching hot Aussie summer, you’ll know that it’s an abundant energy source!

The sun’s rays can be converted into electricity using camping solar panels. Solar panels are made up of photovoltaic cells that capture sunlight and convert it into direct current electricity. This electricity can then be used immediately or stored in batteries for later use.

Solar energy can power anything from small gadgets to entire homes. In the context of camping, it’s especially useful for running fridges, lights and other 12V appliances without relying on traditional power sources.

Can you run a fridge off a solar panel?

Yes, you can run a 12V fridge from a solar panel! However, to ensure uninterrupted power you’ll need to consider the following factors:

• Panel size: A 200W panel is generally sufficient for most small to medium-sized camping fridges, depending on your location and weather conditions.
• Battery backup: As solar is dependent on the sun’s rays, solar panels can’t produce energy at night. A solar-compatible battery is essential to store energy for use when the sun isn’t shining.

Why use solar panels for camping fridges?

Let’s get into the nitty-gritty of why you’d consider using solar to power your camping fridge.

First off, solar power is incredibly eco-friendly as it is a clean and renewable energy source. This enables you to enjoy the great outdoors, whilst also reducing your carbon footprint - win, win!

Secondly, solar can save you money in the long term. After the initial investment, solar panels can save you heaps on fuel costs, especially for longer trips.

Another benefit you might not have considered is silent operation. Unlike noisy generators, solar panels operate silently, which is a definite plus when you are trying to relax in nature.

Finally, solar panels are incredibly versatile! Solar panels can power more than just your fridge—think lights, charging devices or even a small fan.

What power sources can I use whilst camping?

With many power options available, from generators to vehicle charging, you may be wondering which power source is right for you.

Solar power is ideal for when you’re camping off-grid and want a sustainable, quiet and low-maintenance power source. Solar is perfect for long stays, as it continuously charges your batteries during the day. It's especially effective for running low-power devices or keeping your battery topped up.

Petrol portable generators are best suited for situations where you need a lot of power quickly or when sunlight is scarce. While louder and less eco-friendly, they can provide substantial energy for high-demand equipment.

Charging your 12V battery from your car or van is handy for shorter trips or when solar and generators aren't feasible. However, this method can strain your vehicle’s battery if used excessively and is generally slower than the other options.

What size solar panel do I need to power a camping fridge?

This is the most common question for anyone when planning a longer camping trip. The size of the solar panel you need depends on several factors:

• Fridge power consumption: Check your fridge’s power consumption. As a general guide, the average camping fridge uses between 30-50 watts per hour. A larger fridge or higher usage might require a bigger panel or multiple panels. Unsure which camping fridge is right for you? Check out our guide to choosing the best camping fridge.
• Daily power usage: Once you know your fridge’s power consumption, you can calculate its daily power usage. You can do this by multiplying the fridge's wattage by the number of hours it runs daily. E.g. 40 watts x 24 hours = 960 watt-hours per day.
• Sunlight hours: Calculate based on peak sunlight hours. If you get 5 hours of sunlight, a 200W panel will generate around 1000 watt-hours.

Let’s recap!

Here are some simple calculations you can do to work out how big a solar panel to run a fridge.

Daily energy needs = Fridge Power (in watts) x Daily Running Hours

Solar Panel Output = Panel Wattage x Hours of Sunlight

Additional factors to consider when determining solar panel size for a camping fridge

The equations listed above are a good starting point to determine the size of the solar panel required for a camping fridge, however, some other factors may come into play in determining your energy requirements.

The climate you are camping in can greatly impact your fridge’s energy consumption. In hotter climates (such as the summer in most of Australia), your fridge will work harder, consuming more power.

Your camping location can also play a part in determining your solar panel's ability to capture the sun’s rays. The amount of available sunlight can vary greatly depending on your location and the time of year.

Lastly, you need to ensure your battery can store enough power to last through cloudy days or long nights.

Pro tip! Reduce energy consumption by keeping the fridge cool before packing, limiting door openings and using an insulated cover.

Will a 200W solar panel run a fridge?

In most cases, yes! A 200W solar panel can produce around 1000 watt-hours of energy in a day under good conditions, making it suitable for use with fridges that use up to 40 watts per hour. Pairing your solar panel with a 100Ah deep cycle battery gives you a reliable energy source day and night.

Can a 300W solar panel run a fridge?

A 300W solar panel is suitable for camping fridges with higher energy consumption. For smaller 30-40W fridges a 300W solar panel may be overkill, but could be useful if you intend to run multiple appliances.

How to connect a 12V fridge to a solar panel

Now you know how to calculate your fridge’s solar power needs, let’s take a look at how to connect a standard 12V camping fridge to a solar panel.

• Step 1: Set up your solar panel where it gets maximum sunlight, look for clear spaces without too much overhang from trees that will block the sun’s rays and cast shadows throughout the day.
• Step 2: Connect the panel to a solar charge controller to prevent overcharging.
• Step 3: Attach the charge controller to a compatible deep-cycle battery.
• Step 4: Finally, connect your 12V fridge to the battery.

Pro tip! Always use appropriate cables and connectors to ensure efficiency and prevent voltage drop. Check out our extensive range of solar cables and wiring to find the best setup option for your needs.

Pros and cons of using solar to power your fridge

When it comes to powering your camping fridge with solar energy, there are several factors to consider before investing. While solar power offers numerous advantages, it’s not without its challenges. Let’s dive into the pros and cons to see how solar energy stacks up for your off-grid adventures.

Pros:

• Sustainable: Solar energy is renewable and reduces reliance on fossil fuels.
