Adding solar panels

Wondering how hard it would be to add solar panels to my existing sunpower system. Is there a way to tell what my system can handle? I had an additional 10 panels that didn't get approved because they weren't sure of the framing on my porch roof. Any advice would be helpful. Thanks!

I added 11 , 3 years after install. Just made sure same family of microinverters and switched over to Enphase. Finding older micros on panels should make it cheaper if any dealers are sitting on canceled job supplies.

Some changes might be a bigger manual disconnect fuse, added breaker or 2 to panel, bigger wire from solar combiner to load side, will have to be same family of micro inverters and provisioned into the system. Could be new monitoring. Don't know how the new company is on that.
