One panel not working (1 Viewer)

[rvnib]

Hi everyone,

We're currently in Turkey with the temperature in the late 30's. We've recently noticed that only one panel on our NDS display has the sun symbol on (we have 2 x 160 watt flexi-panels stuck to the roof of the motorhome), despite our batteries being at 60%. The amps being generated is between 6-7. Last year in similar conditions in Italy we could rely out batteries getting double the amps. Having said this, there have been a few occasions when both panels seem to be operating with a double digit amp output.

Any thoughts or guidance would be gratefully received. Please excuse any terminology ignorance.

Thanks

Jonathan

Flexible panels notorious for premature failure due to heat !

Many thanks for this reply. I'm in communication with the company concerned at present. Do you have any information on the reasons these panels are prone to failure due to heat. Thanks

They are usually stuck down to a solid surface with no airflow underneath and get hot and degrade.If your in Turkey with air temps of 30 Dec C then they will get even hotter.when you do replace best to try to get them fitted with a gap underneath to allow free flow of air and some cooling.

Doesn’t B1 & B2 mean two battery banks? i. e. Engine and hab batteries

Yes that's correct, the engine battery gets a charge when the habitation batteries are full

I think maybe what stevewagner was trying to say is; How do you know from the photograph that only one panel is working?
