no they don't, i don't believe so... ive not changed the power deal since we got the solar. so i doubt it... however who knows with them. Ill check it out though. its just the plan they offered me was "lets pay you DOUBLE" (and then the fine print but for a bit) and i didn't accept the new deal. They don't have access to the power stored in the battery. It was jsut they offered to pay more for a few kwh of power.... im like.... nope....

i don't believe they have taken anything out of the battery....
