Ingo Posted July 14, 2019 Share Posted July 14, 2019 I have limited roof space and was wondering if I can mix portrait and landscape panels to fill all available space. The roof is facing NE and with the JA Solar 315 modules it seems it will fit perfectly (I think). The furthest panel is also +-22m to 25m from my DB so would like to keep the voltage as high as possible as not to buy too much expensive thick cable. The idea is to run a Fronius Primo 3.0 with 4mm wire from the panels which gives me <1% loss with them all in series. I know it goes against any aesthetics but it's what I've been dealt with. The drawing is roughly too scale. Will this work or am I missing something obvious in my calculations? Quote Link to comment Share on other sites More sharing options...
DeepBass9 Posted July 15, 2019 Share Posted July 15, 2019 (edited) The orientation makes no difference. How are you going to connect them, all in one string? 4mm2 cable will probably do the job, but I would rather go for so something thicker. The cables on the panels looks like 6 or 8mm2 so Iwould rather use a similar size to that. The cables on the panels are too short to daisy chain them together in landscape orientation, so you will need to extend them to join them together.

Ingo Posted July 15, 2019 Author Share Posted July 15, 2019 Yea, I am with you on that. I double-checked and the panel leads are indeed 4mm2 as per the datasheet and 1m in length. The panels are 1650x991 which will make them interconnect perfectly except for the far-right ones that needs a small extension.

Leonb Posted May 26, 2023 Share Posted May 26, 2023 Hi Old thread but relevant to what I'm planning. Can different orientated panels (3 x landscape + 6 x portrait as in pic above) be used on the same string? Quote Link to comment Share on other sites More sharing options...
