Strategy
This upgrade is comparable to an Antenna in terms of how quickly it charges your Special gauge. A Solar Panel will obviously provide a more consistent benefit, but it will never work better in any given situation, regardless of your gameplay.

Solar Panel is most useful in situations where you cannot get into position to use your primary or secondary attacks and charge your Special, such as on close-range and direct-fire tanks.
