The "10 gauge" MC4 pigtails on my 230w solar panel turned out to be aluminum wire. I found out when I cut the ends off to connect them to some #8 wire I have.
I wonder if the 25 ft extensions you can get for those solar panel MC4s are also aluminum. If so, you need to "adjust" your voltage drop calculations to al vs cu.
