A clear hot afternoon can produce less solar power than a cooler bright day.

A 400W solar panel is not promising to deliver 400W every moment it sees daylight.

The sun is shining, the roof has solar panels, and the house still goes dark during an outage.

An EV charging adapter that physically fits is not automatically suitable for the vehicle, station, or charging mode.

Regenerative braking recovers some energy that would otherwise become heat during slowing.

An EV can travel fewer miles per kilowatt-hour on a fast highway trip than on a moderate-speed route.

An EV charging rate can fall when another car connects nearby without either vehicle developing a fault.

A powerful charging station cannot make a cold EV battery accept unlimited power.

A higher-power EV charging installation can shorten some sessions, but only if the vehicle and site can use it.

Level 1 charging is slow compared with a dedicated higher-power setup, but slow does not automatically mean useless.
