Here is some info on the orientation of the JAXA SLIM lander's solar panels.
The solar panels are facing southwest. NW would have been better, since SLIM is at 13.3°S. In the image taken by LEV-2, the solar panels are not visible.
So, there is some hope of a revival as the Sun moves farther west.
This is based on matching an image from a similar location (but from a much higher angle) using the lunar map at LROC. The shadows imply it too.
