Most panels are from China. Panels have a very long lifetime. Over their lifetime they generate way more than their price in oil. Europe is not a huge producer of oil and relies on imports to sustain its usage. Sourcing panels is effectively reducing the amount of money leaving Europe in the long term.

China. With that said, they have so much solar PV capacity that they’re barely breaking even, even when exporting tens of GW of PV panels a month. I argue it’s a net positive the solar PV printers in China are kept in business to maintain their annual output, the world needs as much solar PV as it can produce as fast as possible.
