With a system already on your home, it may be possible to increase power by adding panels even with a 7000W inverter already. If not, the orientation of your carport should have the roof sloping south with minimal shade. As the previous commenter said, size the port for roof and panel weight, making sure it accommodates the largest intended vehicle. Consider Enphase micro inverters for ease of construction, accommodation of shading, and claiming all power above 7000W. Please note that we have 7200W hooked up to our original 6000W inverter, but lose very little power due to sun angle, clouds, and desert temperatures. Of course, your mileage will vary. It will help if you update your info to include location beyond the implied "Maui."Mauileaves wrote:Ok solar tech people, what would I need to make a little solar carport? Only for leaf charging. Not to concerned with impressive charging numbers, half the reason is to get my black Leaf out of the sun all day at work.
Indeed I think that was the system I dug into a few weeks ago. My conclusion is that it has value for companies wanting to make a very visible (and expensive) statement OR perhaps for an off-grid solution. However, I doubt that we'll see these popping up in state parks and forests to allow EV drivers to visit. Would be rather nice to have one at a wilderness trail-head, but who is going to pay $40K to put it there eh?ishiyakazuo wrote:You mean like this?

Oh yeah, no doubt! I just thought it was worth bringing in, because obviously someone thought it wasn't a silly idea, and went as far as to productize itSlow1 wrote:Indeed I think that was the system I dug into a few weeks ago.

Certainly not worth that cost for a home solution as I'm assuming OP is looking for... I have to imagine that a grid-tied home built solution would come in well under that budget.
Agreed. The thing I wonder about is if that company would consider building a grid-tied version (skip the batteries) that could perhaps be deployed to condos/apts/homes as a real turn-key solution. I wonder what the price point on that would be and how it would compare to other options.ishiyakazuo wrote: Oh yeah, no doubt!
