Certainly, but it's still a real question!
It is possible to transfer solar electricity "from East to West", but still in a limited way.
But if you have a scenario, let's say for Europe, shall I listen to you?
interest yourself
to HVDC (high voltage direct current) networks which transport electricity over thousands of km with less than 10% losses.
Here is in red the existing network for Europe, in green the lines approved for construction, and in blue the projects
Interesting. I knew the Russians were already doing it but I didn't know that we had direct current high voltage lines in Europe and even as far as France.
I hope it will continue, and even up to the user (we can dream).
We are in alternative because in the Tesla / Edison fight, Tesla won. Tesla was right at the time, because we needed a change in voltages but only had the transformers for this use.
But today with power electronics, we no longer need them. And even with us, users, we surely have more than one switching power supply unit. However, a switching power supply first consists of straightening the 230v AC to DC before the voltage change. So if we had direct current directly in the house, switching power supplies would be easier to manufacture and with better efficiency. Multiplied by millions, that would not be negligible. The disadvantage is for large equipment (washing machine for example), there all the motors would have to be replaced.
