I have had a renogy 100 watt panel for several years, and it works well, but a few months ago one of the wires pulled loose.

My son just replaced all these original connectors with “crimp on, fork connectors”, which should be a permanent fix. https://au.renogy.com/renogy-100-watt-12-volt-monocrystalline-solar-panel-compact-design-1/
