How are evacuated tubes different from flat solar panel in terms of installation and maintenance?

Evacuated tubes and flat panels both collect solar energy.  Besides their performance, they are also different in terms of installation requirements and maintenance.  Because evacuated tubes are made of several tubes and have spaces between the tubes, they require less structural work compared to flat panels.  Flat panels require more stable frames to prevent wind from moving the panels.  Wind passes through evacuated tubes.

When evacuated tubes are damaged, only the damaged tubes need to be replaced.
