What is the difference between relying on Superchargers and relying on fuel delivery? Either way you have an outside provider. Propane costs thousands more and you are still reliant on someone else. You are expecting the apocalypse will come and all Superchargers will fail but propane delivery will still come reliably?
A tank of fuel can sit. Almost indefinitely. Ready and waiting for when its needed. If there is a widespread power failure, The SC system goes down, It rains like all hell for days, social unrest, etc. That tank of fuel is ready as the last stand backup. It is NOT meant to be constantly used. I have one myself. I live in the middle of a tornado farm. When there is no power, trees everywhere, roads blocked.... I STILL have power.
He has Grid power.
Unless you live in rainy mountains like I do where you can go months without solar... or where the temps stay painfully low... and your grid can be out for a week... the price of a generac install is just not worth it.
You put 60k miles a year split between two cars? Ouch.
So you are saying that you can produce 40 KwH per day using 10 panels?
That looks about right for an M3 or MY but not for an MX or CT which will probably be, maybe, 30% less efficient. So maybe 4.5 KW just for the CT at 80 miles per day.
We only drive 3 days a week in the Model Y and lately not in the Model 3 at all. My evaluation was based on the amount of power I would need to drive 80 miles in a day, not how many miles I drive in a year. I drive about 16K per year (at least, that is what my Model Y tells me). I would not want to wait 2 days to charge my car 20%.
Panels come in 50, 100, 300, 600, and 400 watt versions, so... 'panel' is a bad metric. I have 12w panels and 40w panels, too.
Then you need to average it over more days of solar, then. No one is suggesting you charge it only 10% per day (as 1/7th your range is greater than than that).
I was just using my array as an example to show that it doesn’t seem like it could work without me doubling my array (which is more roof than I have), and wondering how others could do it. That said I realize that I made a mistake. If I drive 80 miles (about 1/3rd my useful range), then that is about 25 KwH. Then you need only guess the relative efficiency of the CT compared to the MYLR and then you can figure out how many panels of a particular size you need to charge your truck to go 80 miles in ideal conditions. I used a 2/3 value for efficiency and yes I pulled that out of a hat but it is similar to the MX. so about 38 KwH. My array couldn’t do that in a perfect day and that is why I wondered out loud in the first place.
If you can't do everything you want via your solar panels, maybe there's a way to do it more efficiently. If you're only getting one mile per 300Wh, maybe you should get a more efficient vehicle to do some of those miles by.
You'd still rely on the propane-delivery guy
The more energy agnostic you are, the better you're off. And a propane tank can sit pressurized for years with hardly any charge loss.
