Is it harmful to leave a solar panel connected while under partial shade, and to leave it connected during the night?
This is potentially a very basic question. I've got a Canadian Solar 445W bifacial panel (CS3W-445MB-AG, see: https://solarshop.baywa-re.ca/site/assets/Product Specs/CAN-3713_DS.pdf). I've read that continual exposure to partial shade can damage the solar panels by forcing their bypass diodes to compensate and work extra hard. Is this a prevalent issue, and/or was this more of an issue with earlier models of solar panels?
As such, I'm wondering if I should disconnect my solar panels when I'm parked under dappled shade, and during the night? (I have a dual-pole breaker installed so it'd be easy to disconnect the solar panel).
