(Apologies in advance if I'm not using quite the technical right terms. I'm an accountant, not an engineer.)
I have an existing 5.9KW solar system for my home, which covers our home plus about 1k KWh to spare over the course of a year when we have a mild summer (Southern California had a very mild summer this year). I suspect that a normal summer would wipe out that surplus. Since I just got my Leaf, I'd like to add more panels so I can drive on sunlight.
How much capacity do I need?
I expect to drive my Leaf about 12-14k miles per year. Over the first month, I'm averaging 4.0 miles per KWh per the Leaf's dashboard. That would 'suggest' that I would consume 3,000 - 3,500 KWh per year.
Now I'm assuming that is the amount drawn from the charged battery, not the amount drawn from the wall outlet as there would be overhead and inefficiencies in the charging process. I will be installing a 30amp level 2 charger (Scheider EVPlus). But I have no clue how to estimate the amount of solar production I will need to get that 3,000 - 3,500 KWhs into my battery. Can anyone guide me on this point?
And then, how do I convert the KWh production need into a KW specification when requesting bids from my solar installer?
Thanks!
