How much electricity (in excess of day-time domestic requirements) do your panels produce?

We have not insubstantial 9Kw PV system....which today produced 50Kw
but we used about 15kw...so 35kw net. Given the car battery is 75kw
it would take a bit over two days of PV power from dead flat.
But driving the battery to exhaustion does not look like it will be our typical usage.
Our Tesla wall charger is not installed just yet, it will fully charge the car in 9 hours. The best charge we can get from a wall socket at the moment looks to be about 2 Kw per hour. So 37 hours from dead flat. I just drove to the local shops and back and that little errand chewed up 3% of the car's charge....not even a 1Kw so maybe 5 cents worth of ergs.
