Re: Solar panels stainless steel mounted vs soft panels

Hi Kent& Iris,

See pictures of solar panels above the cockpit, they are hardly visible from the side...

These show 4 Solar panel Suntech STP190S24Ad plus. 3 years old now and they cannot withstand the tropical  temperatures: the backsheet melts and salt does the rest...

I will replacle with 3 Trina Solar vertex S  TSM-DE09.08_405W, slightly longer but almost the same total width.

Of cause you have shading issues so all panels are in parallel.

Hope this helpfull in some way,

Stefan Jeukendrup

I have 600 watts (two series pairs) in hard panels on the stern arch that give a maximum of 16A at 24v on sunny days.  I also have 250W of soft panels on the Bimini which produce a maximum of 3A in bright sun (in Maine now),but in less than ideal conditions, they hardly produce anything.  I recommend that you stick with hard panels.  I'm thinking of replacing them with more hard panels if I can figure out how to mount them above the Bimini.
