A Tesla does about 4 miles per kw, give or take. So 100 miles would use about 25 KWH. Typical solar panel setups for domestic usage are around 3-4 KW. So depending on the season, you could get to 25KWH in a single day in the summer and you might struggle to get there in a week in the winter. All depends on you latitude, cloud coverage, etc. If you are in the north of Scottland, probably not a great plan in the winter but fantastic yields in the summer due to the long days.
