Solar panel output only 9v

[OllieGBR]

I’ve also checked this directly at the two solar cables.
Anyone else seen this issue? I assume it’s a problem with the panel itself?

Thanks

My panel failed recently. I borrowed a spare panel to prove everything else but mine was pointing towards the panel itself and it turned out it was. Although mine seemed to output slightly until it had direct sunlight and then volts died off.

I had exactly the same issue = dead panel. Replaced same = all ok.

defo check the panel.

with good strong light you should see a decent PV voltage.

even if the battery is full and not drawing any amps.

75v here (3x 100w panels in series) - green

drawing 0A as the battery is full - red

Gents, which panels were these? I’ve just re-read @Dellmassive’s posts on solar and have got the Photonics Universe page open in another tab!!

PS Sorry for your loss(es).

It was very strong light - perfect sunshine

Mine was a generic Chinese one. Now replaced with a Carbest 160W. So far so good.

Mine was a 130 watt panel from photonic universe. Lasted 2 years. I have bought a cheaper one from amazon this time and see how long that lasts now.

Mine’s an NDS 140W flexible panel. PIA to remove and replace!!
