What to do if the solar panels on your motorhome aren't working

It is rare that your solar panel will stop working unless there is a problem with your wiring or connections; however, there are a few things to check to ensure your solar power performs at optimum levels. 

Solar panel clean: 

  • Check that your solar panel is clean.   
  • If a thick dirty film is covering the panel, this will affect the input. 
  • The TrailLite service centre offers roof cleans, which can be added to your annual service check for an additional charge. 

Check the solar controller:

  • Check that there are lights on your solar controller or charging indicator on your Finscan screen.   
  • You will find your solar controller in one of your cupboards or under a seat (Euro models).
  • For TrailLite, the CTEK controller is located in the battery compartment. 

Test to complete before contacting TrailLite Service Centre:

  • As a test, take note of the voltage.
  • Turn the fridge to the battery setting in your motorhome/caravan.
  • Take note if the voltage drops on your battery monitor.  
  • Does the charge indicator read differently?  
  • How much does the voltage drop?  
  • What solar capacity do you have on your motorhome/caravan?  
  • Keep a record of what happens so that when you call our Traillite Service Centre, you will be able to answer these questions. 

Note:

During the winter months, your solar will not bring in much charge due to the sun's location, so you cannot fully rely on your solar panels during these months. 

If you would like to upgrade your solar panels or discuss the solar and electrical systems in your motorhome or caravan, please contact the TrailLite Service Centre.
