You’re also making assumptions in that the volatile memory lost power and thus must have been cleared at some point. I dont think there is a right or a wrong based on the knowledge i have I just am throwing out a random guess.

On embedded controllers you are usually heavily limited with nonvolatile memory.

If the data is temporarily stored until it is transmitted and then is not considered to be needed anymore I see no reason as to why that would need to be stored locally forever.

It is possible that the data is just never saved in non-volatile memory meaning that once power is lost that the values are also lost. In which case its not really deleting the information but rather just that information is just never intentionally saved.

P.S. I am not a tesla fan boy just wanted to give this tiny insight.

You are at least completely and utterly wrong about tracking solar not typically being built anymore. Any major solar site uses tracking if you have a couple acres on a corner maybe not but I think you are being a bit too general. Panels are only one of many costs per solar panel installation, its still cost effective overall to increase efficiency.

The more I think about it doesn’t trump just want to raise taxes without explicitly raising taxes.
