Use this on a 100w solar panel. Make a small MC4 for this adapter and use it in mine barn outside and currently covered in snow for months. Very durable cable compared to all other SAE cables I've found. I'm not sure what the voltage drop is due to the way I mounted my panel, over distance (convenience at top maximum efficiency - right up to the wall of my south-facing barn), but I know it would be worse with the spaghetti-noodle cables so common in this form factor.
