The Climate, Environment and Energy Thread

it's no coincidence that solar panel installs are typically 5kW!

I think you should revise that statement. At least if you are referring to your typical residential solar panel install.

The reason that they are about 5kw, is that is about the real estate available on your average house.

When i got mine 10-odd years ago, we got 3.3kw simply due to price, but was an upgrade on what the standard install was at the time. If we maxed out our roof space, we

The beautiful thing about EVs, is that the laws of physics for electrical engineering are well known, and motors and transformers are already very efficient. So do not be sucked into some company claiming they found a new way to improve efficiency or range outside of providing bigger batteries, any such claim is bullcrap because there isn't enough scope left in designs to gain anything significant! Work done(kilometers driven or loads towed) have to obey the basic kinetic and potential energy equations. Unfortunately, the car industry is still full of people who grew up on "our car is more efficient" or "more economical", so much of the same spin remains.

'New technology' will come in terms of KERS and the like. Recovering energy, thus using less energy by comparison.
