200W Solar panel & Renogy 50A DC-DC

[slocumjoseph]

I just posted this on the wrong thread...

Just when I thought I had cracked the “which solar panels” question another potential problem comes up. For me, height is critical so I can’t have anything more than 2cms above the roof. I want 200w of solar power up there and 2x100w panels would be fine. I have now discovered the Flexi panels with rear facing junction boxes. Although I’d have to drill a bigger hole in the roof they would be under might height criteria. Then it was suggested one 200w. panel means one hole. Sounds good but now I’m wondering if the Renogy 50A DC-DC charger and MPPT that I’m planning on buying would be able to handle all that at once. Any advice gratefully received before I vanish up my own conduit!

Is it this one;

200W Semi-Flexible Rear junction box solar panel for boats, caravans, vans – ITS Technologies

These 200w flexible solar panels with rear junction box are designed for narrowboats, RVs, motorhomes and yachts. With an unusually high energy yield due to excellent shadow tolerance and temperature stability, these panels give a good option for low narrowboat decks or hot motorhome roofs. T

From the spec;

• Open circuit voltage: 2.8V

This is a typo, maybe it should be 28V? This is too much for the the DCC50s

The 180W panel is 23.9V VOC which is ok for you, unfortunately it's more expensive, and 20W less;

180W Semi-Flexible Rear junction box solar panel for boats, caravans, vans – ITS Technologies

These 160w flexible solar panels with rear junction box are designed for narrowboats, RVs, motorhomes and yachts. With an unusually high energy yield due to excellent shadow tolerance and temperature stability, these panels give a good option for low narrowboat decks or hot motorhome roofs. T

The 180w one does seem to fit the bill. Apparently the max voltage from the any solar panel the Renogy unit can handle is 25v so, hopefully this panels 23.9v wont fry it.
