When buying solar panel, should i consider Vmp and Imp? Currently looking at 2 different brands of 550Wp Solar Panel,
1. Longi 550Wp STC Vmp 41.95V, Imp 13.12A
2. Trina Vertex 550Wp STC Vmp 31.6V, Imp 17.40A
Going to install 4 units looking at 2200Wp
I need a little bit of help here on designing my coming solar system with Growatt SPF5000ES 220V(Asia). Im planning to get first string in series 4 x 450watt solar panel, Vmp 41.40v, Imp 10.87A each, I get Vmp approx. 165.6V to get my Growatt working.
Btw, i know this is still far...
