Need to know if solar panels can be hung off a fence like this

Toronto area Canada (43.65 degrees) This fence faces south south east (155 degrees) I'm thinking if I can temporarily mount panels here in summer. looking to capture 1-1.5KW/hr peak to charge 8 kw batteries. Also in winter during grid outage to recharge these batteries as well.

The fence has concreted posts but I'm more concerned it it's safe to mount on a fence that is coated alumimium. Every fence install I see is with wood. Looking to keep under 60 volts.
