I've reported this over there, but I thought I would report it here as well.
If this mod modifies solar panels while 248k is enabled, it stops on startup with the error message:

Failed to load mods: Error while running setup for entity prototype "solar-panel" (solar-panel): next_upgrade target (el_solar_entity) must have the same bounding box.

PostScript: The mods it suggests removing were: Krastorio2, combat-mechanics-overhaul, 248k-redux, and squeak-through.

However, by disabling the modification of solar panels, it works together. I just thought you should know.
