If you are going to try to raise and lower with the zipper closed I suspect that you will have significant problems with the motors not running at the exact same speed. If you are willing to open the zipper for the open and close operations then this may work.

At this point I would suggest calling the vendor and see if they have any other options.

If you get past the zipper concern, I would go with a solar charged battery system, This will allow operation any time of the day and with any luck the motors will be rated at 12 VDC which will give you many options for the battery.
