The EFI System partition needs to be formatted with a file system whose specification is maintained as part of the UEFI specification; the file system itself is based on the FAT file system but is independent from the original FAT specification.
I consider two ways to estimate the âcost of electricity.â One way would be to simply assume 10 years of annual costs amounting to $2,250 a year, or a total of $22,500. Another way of estimating the cost of electricity would be the cost of an ordinary solar system, or $21,000 as shown in the example above. So the cost of a Tesla retrofit system would be in the range of $33,000 to $37,500.
