Solar PV + Grid Tie + Super Cap

I have an existing PV setup with a grid tie inverter.


I have been thinking about what possible improvements I can make to the system and I came across other people who have used super capacitors.

My system does not use batteries, so my question is:

Once I charge up the cap, and hook it up between the panels and inverter, what happens the next day when the cap is fully drained and then the sun comes out and hits the cap with full voltage?

Will this work or will the cap be damaged or possibly damage the panels/inverter?

The sun don't hit with full voltage, it hits with full current (Isc) whereupon the cap voltage rises linearly from 0 - until it reaches full voltage (Voc).
It won't damage the panels or the cap's. How the inverter will react to this I can't say, it's probably model specific anyway.
