Summary
Tesla’s registrations in France dropped 63% in January, their lowest since August 2022, far outpacing the broader total EV sales’ 0.5% decline.
Tesla registrations across EU countries fell 13% last year, with Germany accounting for much of the decline.
Sales in Germany, Tesla’s biggest European market, also fell 41% last year due to an aging lineup, competition, and subsidy cuts.
CEO Elon Musk’s political involvement, including support for Germany’s far-right party, may be affecting demand.
For the residential market it looks like this.
Panels - Tesla solar panels are nothing special. They use other manufacturer’s panels. They generally choose acceptable middle-of-the-road models, not the high end, not the low end.
Panel integration to homes - Telsa does have a clever part for linking into an existing home wiring panel that can be faster/cheaper that the common methods called a meter collar. However it is only certified for use in some states so far. Also, other companies are coming out with their own meter collar, but I concede that Tesla was the first to do this.
Battery - Tesla Powerwall is one of the most popular home battery options because of its large capacity relative to its price. However, there have been bad runs with some of its models with its inverter prematurely failing or running extra hot and shutting down. Overall its still considered higher quality unit and user experience. However, its not the only battery on the market. In the USA solar vendor specific batteries exist with pros and cons compared to Tesla. Enphase is one of the leaders in home solar, and they make an excellent (but expensive) battery system. Franklin also makes a vendor neutral battery that is highly regarded.
In all of these Tesla home solar products one thing that is universally agreed to is how horrible the Tesla customer service experience is. Getting a hold of a human is nearly impossible. When you do the human will frequently not follow up, and you’ll find out that human is gone and you have to go through the process again to get your issue addressed. Replacement parts can be delayed by months mean, and not infrequently the subcontractors used to install the equipment cause problems or damage to the houses where the install occurs.
I chose to skip Tesla and did not use them for any of my home solar install and I’m very glad I did.
Thanks for your thorough reply. We have solar on our home. I’d like to get a battery back up, but am a little annoyed on the price of that, and will not go
nazitesla any time in the near future.Unless you’re in California or a couple other pockets of very high time-of-use (TOU) rates, home batteries don’t make economic sense right now. However, there are more than economic reasons for some folks for home batteries: medical equipment in the home for a loved one, backup power for high outage areas, personal actions on climate concerns. None of these are good “investments” returns though for batteries.
I bought a small amount of very expensive batteries, but where I live we have true 1:1 net metering so there isn’t any economic benefit.
Enphase did some of our stuff. I’ve looked at their offerings. I’m a little miffed that I have a huge battery 77kWh on wheels even, and can’t use that more efficiently to power the house. It has V2L, but at 1800W max. Whatcha think about using that V2L to run a pump, send the water up in to a lovely medium sized water tower which I’m sure the HOA would appreciate, and generate back some electrons while I take a shower, water the garden, etc?
Is that a limitation of Enphase or your car? Enphase does have a bidirectional charger to do exactly what you’re describing if your car is compatible with it. I’m in the same situation BTW with an incompatible car.
My EV does V2L (vehicle to load), but at a miniscule 1800watts. I can use a water boiler, or an induction hob, but not both at the same time. The problem is getting the power back to the house fast enough to be useful. Thanks for the Enphase link, I’m always a bit scared when they don’t show a price. I"ll look deeper when I have a chance.
Talk to someone actually qualified (I’m not), but there is a VERY NARROW set of circumstances that I could see your car working, as-is, to power your home.
The IQ System Controller 3 can have a “generator” input (designed for use with a gasoline, propane, or natural gas generator. If you have the older Enphase battery system (the T series) and only ONE of them, and only their smallest one the 3T, then you can use the Generator input to input 1.83kw aka 1830w.
Well that looks interesting. TY! Tho’ I really like the Gravity Battery conceptually. :-D
While I appreciate the Rube Goldberg nature of the gravity battery, the mechanical losses of energy would be significant. You’d likely lose at least 20% of the energy bringing your total usable down to 1440w. Just to let you know for scale that 1800w you have available is pretty significant energy to power a house if you’re talking lights, refrigeration, and general electronics. I just checked right now and my whole house is only pulling 1100w. That’s with the HVAC fan running moving air, but no heating or cooling being generated at this moment, no cooking or EV charging either.
