IF I lived somewhere like Arizona it would be interesting. However where I live in the winter I don't get enough sunlight to charge a solar powered security light.
It is interesting though.
Couple of questions I would have is how long do the solar panels last and how much does it cost to replace them.
That depends a lot. First thing I would look at is the electronics. Good invertors will last over 15 years, but cheap offers usually come with crap electronics and you likely be looking at big repair bills along the way.
Second is the material mono and polysilicon can last over 20 years others like Cigs panels still have to prove themselves and I do have some worries there.
Further you would have to look at your personal situation. For instance if you have trees around you have to look at the electrical configuration, shadows and leaves are a nuisance for yield but can also wear out your panels faster depending on how they are wired. Also if you live in an area with hail you want to look at the glass. One hailstorm can destroy years of savings (been there).
It is not one answer. It pays to get yourself informed and take the best option for your situation and not go for the cheapest offer. Then 15+ years should be no problem.
One way to get really good panels is to look at sales from solar farms. They replace the panels when they get out of population, which is still perfect for many years of domestic use.
I also have an issue in winter but I have a combination of solar and wind (co-owned) In winter wind tends to offset solar so that I end up net zero all year round.

Exemption from 25% VAT on purchase (2001-)
No annual road tax (1996-)
No charges on toll roads or ferries (1997- 2017).
Maximum 50% of the total amount on ferry fares for electric vehicles (2018-)
Maximum 50% of the total amount on toll roads (2019)
Free municipal parking (1999- 2017)
Parking fee for EVs was introduced locally with an upper limit of a maximum 50% of the full price (2018-)
Access to bus lanes (2005-).
New rules allow local authorities to limit the access to only include EVs that carry one or more passengers (2016)
50 % reduced company car tax (2000-2018).
Company car tax reduction reduced to 40% (2018-)
Exemption from 25% VAT on leasing (2015)

As a point of reference re; the title of this thread; i recently got a gig driving a delivery truck that’s all electric. It’s a converted Isuzu from an outfit called Nordressa. It’s essentially last mile commercial delivery with some crosstown highway. Round about 200km, over 8-12 hrs depending, and then gets plugged in at the warehouse at the end of the day. For the task at hand it does better than the original diesel version. The lack of engine vibration really helps to reduce fatigue on long shifts.

Audi stops the development of internal combustion engines. I can imagine they have EURO7 spec ready for the next decade but still a strong signal.

Zero emissions ICE under development, the idea is to extract nitrogen from the air before the combustion so only oxigen is burnt, using a ceramic membrane.
As they say it will be difficult to use on small cars but perfectly doable for trucks, trains, etc which are the most difficult vehicles to electrify

That doesn’t make any sense to me! Nitrogen is iirc a key ingredient in combustion, it’s one reason chemical super charging (nitrous oxide) is so effective.

Nitrous oxide isn't about the nitrogen, it's about the oxygen. The oxide bit.
Nitrous oxide is N2O. It breaks down to give nitrogen (N2) and an oxygen atom that can burn a fuel molecule.
In an ideal set up, you'd just use fuel and oxygen to give perfect combustion. It's what some rockets do - burn hydrogen or kerosene with pure oxygen.

What fuel are they burning? Bio derived hydrocarbons or hydrogen burnt in pure oxygen would be zero emissions, so long as the hydrogen is produced using renewable, of course.
