It costs them a lot less per kg to lift to orbit, maybe they're just throwing more panel area at the problem? They're claiming 22.8% efficiency for their earthbound panels so that's only a ~50% increase in panel weight.

More panels means more atmospheric drag in LEO. This leads to a shorter lifespan of the satellite.

Maybe they're equipping them all with EM drives? :P
