BMW i4 M50 overheats with restricted power and charging during 1000 km challenge

Actually, solar panels are very durable and hail damage is rare. As you might imagine, weather conditions were included in development.
There are many articles that speak to wind and hail weather.
I believe mine are guaranteed up to 150 mph wind and hail damage; I would have to look it up. But this is one of the many questions I had before investing in a solar project.
This. Mine is 155mph, plus there is a thing called insurance.
 
Or in the Winter after they get a nice, crusty 2" layer of frozen snow on them. Followed by a weeks worth of below freezing temperatures.
In CO, where I live, snow melts from the roofs the next day or a few hours after the storm. Temperatures absolutely DO NOT have anything to do with energy generation through panels.

Considering your location, I am not sure why would that be an issue at all?
 
On average, there are 164 sunny days per year in Akron(OH).
The US average is 205 sunny days. Akron gets some kind of precipitation, on average, 142 days per year.
Of course even here if I had some solar shingles and it wasnt 48505 dollars a system might make sense.
(except I have a massive maple that shades the house 1/2 the day)
Panels generate energy all the time except at night.
$48,505 is not your final price. You did not include tax deductions in it. With this bill signed, tax deductions went up significantly. I was supposed to get back $14,500, but now it will be more than $20,000.

Interesting.


Would you have still installed the system had their been no taxpayer gratuity?
 
I wonder if this is similar to the Ford Mach-E power issues?
Tesla is far ahead of everyone in EV development; clearly their engineering is superior.
The big boys will still have their loyalists to bouy them up, but real world use is showing companies like GM, Ford, Porsche Audi and BMW are having EV related problems.

Ford clearly under spec'd both the high voltage connection and the internal heat as evidenced by the recall of every Mach e, and the 5 second cap on the GT's throttle.

There seems to be a trend forming with battery issues in pouch and prisms.

The lightnings inability to high speed charge beyond 150 is also very telling. Such a huge pack should swallow 250-350.

Bjorn talks about how critical it is that each individual battery/ module/ pouch needs to be incredibly close in voltage to the others in order to safely high speed charge and that when variances occur the entire assembly essentially has to drop to the lowest common denominator in the group or face an inferno. This seems to be the cylindrical biggest advantage.

It was interesting to hear Jim Farley talk about Fords surprise at how much attention that they had to pay to charging and just how much work it is was and will be.

Tesla learned a lot about this and it shows in charge times, performance and degradation over time.

Whats also interesting is that the 400 volt cars are beating the 800 volt cars so at the point of execution theory and reality diverge.

I got a tax credit, but no gratuity. Did the tax credit affect my decision? Of course. Just like it does in many purchases, investments, etc.
Would I have done it without the tax credit? Honestly? Who can say... Perhaps not 4 years ago but I am pretty darn sure I would sooner or later. It is a compelling investment with our CA energy costs.
My solar project has turned out to be one of the best investments I have made. Last month's bill was a whopper, due to 33 days billing cycle. $11.49 to be connected to the PG&E grid. I bet some people are paying $300 per month because of AC this time of year.
I love my solar.

Aha! This is interesting. Charging has to be throttled based on the highest voltage (hottest?) section, if I understand correctly.
I think the biggest rub to me is the loss of power while driving. That's a deal breaker; very disappointing especially for an expensive purchase.

I am going out for a spin in our Model 3, warts and all...

I'm doing an install now. (well in a month)
I'm curious to see which equipment you used and what your expectations will be.
Can you start a thread and share ?

More problems for ford - I cross this twice every trip I make to LA. 99F isnt even hot.

Fors is moving the broken car from dealership to dealership - poeple think "Big Boy" service is universal but its not - for certain cars and the diesel trucks its "we dont have that guy or that guy comes in tues-Fri" type stuff.

Ford must have forgotten to carry the one on this deal. Im bummed as the car is otherwise pretty nice. and Id like to see another American company be competitive.

Service Updates:

On 08/15 - I was informed that Ford Corporate wants my vehicle towed to a local dealership, therefore the service department in Los Banos will not be working on the car.

Conclusion:

I still have a journey left. The car is sitting, dead, at the dealer, 120 miles away. I have no rental and the HVBJB still has to be replaced. I will update this thread with additional information as it happens.
 
So this thing drives 620 miles on $66? At todays prices that is an improvement but at last years fuel prices that is not great. I still think this electric car adaption is a huge error in human history.
I hope everyone else buys into the scam and leaves plenty of cheap oil & gas for me. I love when someone buys a Tesla to save money 😂.

So EVs shouldn’t go up long grades either?

I’m over $300 a month here. Solar is still too expensive for me to be in the energy business. Utilities should do their job and I’ll buy it from them. When looking at solar I have to live in my house for 15years before the ROI makes sense. I’m sure the panels will be old junk by then.

Go to your local Costco and talk to Sunrun, if you haven't done so. Your numbers do not seem right to me. Good luck.

Must have a lot of shade or in a bad area.
Most guys beat 7 some Ive seen are 5
 
In CO, where I live, snow melts from the roofs the next day or a few hours after the storm. Temperatures absolutely DO NOT have anything to do with energy generation through panels.

I'm not talking about temperatures. I'm talking about SNOW in the Midwest. I lived through 38 Winters there. From early December through late February, the roofs had snow on them far more often than not.

Not to mention you only get around 7-1/2 hours of sunshine in the Winter. And that's only assuming there isn't much overcast..... Which there usually is.

My experience has always been they produce more cool than hot.
