Why have solar on your caravan, boat or other RV?

The biggest advantage of having a solar power system in your Caravan, boat or other mobile application is the independence you will acquire from not being reliant on mains power. 

Most modern caravans and motorhome manufacturers include a 12V or 24V battery system that is charged by your vehicle's alternator while the engine is running or by a battery charger when connected to 240V.

This means while you are driving or when you are connected to the electricity grid, for example at a caravan park, your batteries can be charged.

If you wish to stay in a remote location without access to electricity for an extended period without driving around, then you require an alternative power supply to charge the battery.  Generators or running the car engine is an option but most people who wish to enjoy nature do not want the noise and prefer an easier, more sustainable option.

The advantages of Solar Power
Solar power allows you to keep your batteries charged without the noise or the maintenance.  New solar panel technology is lightweight, easy to install and surprisingly affordable. 

Flexible solar panels are particularly suited to caravans, motorhomes and boats as they do not have a frame or glass top and do not require mounting structures.  They simply adhere using an adhesive sealant or VHB tape.

The same technology is available in canvas backed portable solar panels that fold into a small satchel size.

How does solar power work?

What are the main Solar Power components on a caravan/ RV and what do they do?

1) Solar panels.

    Collects the sun’s light rays and products electricity (solar power)

2) Solar charge controller

    Takes the solar power from the panels and charges the batteries. A panel will show the battery charge status.

3) Batteries

    Stores the solar power ready for when you need. This means you can access solar power even if there is no sun shining on the panels.

4) Inverter

    Converts 12V/24V/48V battery voltage to 120V/230V so it can be used at your power points. It also provides information such as the amount of power being produced.
