SPV1040 Breakdown

Dear all,
we are noticing breakdown of SPV1040 in our implementation on a board for energy harvesting from solar panel. The breakdown is only for some board. Here you can see the configuration.
The solar panel is a couple of mono crystalline silicon Sunpower C60 in series configuration. For better performance in low-light condition, we introduce a 100nF capacitor in parallel to CINsns_2.
When the circuit exhibit the breakdown, we can measure an input impedance on Pin 3 (Lx) very low, instead of about 6KOhm of a working unit. Can this help?
Thank you.
