I had a renter hit somethings with my RV and ripped off one of my panels. If they even noticed, they didn't tell me, and I didn't notice myself until a while later when confused why my solar output was so low...
Anyways I need to replace the panel but I can't find an exact replacement:
.
What considerations do I need to keep in mind while replacing a panel with a different panel? I figure the most important is to match the open circuit voltage? How close do I need to be?
My solar arrangement is 3s2p for a total of 1800w, each of the two parallel strings is 120Voc, or around 110V in real world conditions.
My other consideration is that I can't exceed the dimensions of this panel in either width or length.... (Dimensions: 65″ x 39″ x 1.5″)
Here is the out of stock panel: https://store.santansolar.com/product/santan-solar-300w-65in-new-gradeb/
Any help getting my array back in to form is much appreciated!!!
