Net effect is negative even without weight!

Tesla are 2 tons monsters that charge at 100 000 Watts. 100 Watts produced by integrated panels like this, are most likely not even enough to power up battery controller!

If you charge Tesla from normal house plug in cold, 2KW are not enough to heat up battery pack. So car has to use energy from batteries for heating! So "charging" will actually reduce energy!

Small solar panels are great for fixing parasitic battery drain on vehicles though!

If your argument is "the article is just flat out lying" I don't think we have a set of shared beliefs by which we can have an interesting conversation.
