Sungold Flex solar panels are rubbish.
Originally bought these panels to try some on the electric boat, and some for sale.
I wrote a little history in the Ma-Sea Solar boat thread.

There are 4 panels in series to make 48v nominal for charging the quad bike battery, nominal 48v. First installed 9 April 2021.
If I take a picture like this and number the panels. (This picture is taken today, 27 March 2023, before I removed the 2 failed panels)
Then it was number 3 panel that failed in just over 1 year. Replaced 1 May 2022.
Number 2 panel failed in approximately 1 year and 7 months. Failed late October 2022. Replaced in December 2022.
I noticed not charging maybe a month ago (Late February 2023). It was before the Fully Charged Live show in Sydney.

However, today I replaced 2 more panels (numbers 1 and 4) on the quad bike charge system. Both panels showed zero volts open circuit. So maybe 1 year and 11 months.
Panels 1 and 4 are replaced, photo from the other end.
And charging again
A comment from Revlac (Aaron) in Ma-Sea boat thread about only charging 12v batteries. ........ All of the panels sold to customers, were for charging 12v batteries. All in Caravan's and Campers. A lot of them returned.
