Re: Interesting idea
" when your solar generates excess power "
have you worked out _how much_ solar panel you actually need to take the average EV on your daily commute?
At northern european latitudes it's way more than the average house rooftop and the panels aren't particularly green (hydrofluric waste is threatening the water supplies of around 20 million people)
Unless electricity suddenly goes up to 70p/kWh, The unsubsidised payback period for any solar panel is about 3 times longer than the lifespan of the panels - and as governments are progressively reducing the subsidies it's unlikely anyone "investing" in them as a hobby installation will ever break even.
