Why can t solar panels be popularized
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
The solar panels you indicated in the video (OX-4L 1x6 Photovoltaic Panels) are not retractable. They''re just not. You MAY be able to get a kerbal to disassemble it, and MAYBE that will allow it to be redeployed. I am not sure on that one, I have never tried it myself.
