Usually a capacitor is connected across a PV panel. At night PV generation becomes zero. In this condition, by external means, the capacitor across the PV panel is charged upto the open circuit voltage of the concerned PV panel. Will the PV panel consume power, or being modelled as a diode it will not conduct? Is there a chance that the PV panel will get damaged?
It will be very helpful if any reference is provided.
PV is not damaged by this way, please follow this link:

Dear Arpan Hota
I agree completely with Mr. Mohammad Soroosh, there is no risk to PV damage...
Regards
Dear, Arpan Hota,
In general, whenever irradiation is present (i.e. at sun shining hours) the
PV-Panel acts as a DC-source (like a DC-generator, it source the power), and whenever Irradiation is absent (i.e. at sun set hours) the PV-Panel acts as a DC-load (like a DC Motor, it consumes the power).
Automatically, capacitor discharges (instantly) when there is on irradiation, vice versa. It means connected capacitor across the PV-Panel acts as a surge-tank or surge-reservoir for farther connected circuits.
The parallel capacitors with PV-Panels will not effects (not harmful) at any time (i.e. at full-irradiation time and non-irradiation time also).
