While I am very much on your side and the side of EV and renewable energy, we still need to discuss batteries because so far it broke any calculation and/or use case I have seen.
I have inverter/batteries and solar panels running in Lagos, because there is no stable electricity provided. Batteries hold 5kW and need to be replaced at least every 3 years which makes electricity quite expensive.
For that reason I refuse to switch to solar panels in Thailand despite having plenty of space and sunshine: The panels are cheap and effective, but the battery lifespan kills every calculation.
I don't mind a limited range of 200km and premium on the initial purchase.
But I will not want to worry about battery replacement in my car, when it's the most expensive part.
