I have modelled a solar pv system and a double exponential lightning current model using PSCAD. When I inject the lightning current (10 kA) in the DC side of the system, the results obtained are as follows
I (dc) = 7339.87 A
I (ac) = 2266.87 A
V (dc) = 227.11 V
V (ac) = 1.96 V
The current values are as expected but the voltage developed due to the lightning strike is too low. Increasing the lightning current magnitudes slightly increases the voltage output as well but still as low as 27.52 V for an injection of 100 kA lightning current.
If anyone has idea about this topic or the issue, please feel free to comment here or email me

If a lightning bolt impacts your system directly, it has the potential to melt the panels or inverter. Fortunately, direct hits are uncommon. If lightning strikes near the solar system, a branch current from the bolt can run through the panels, causing high-voltage surges that can damage various system components.
