As with most best thought out plans there must always be a plan B....couldn't find one to rent so bought this one.
Word to the wise, if you are looking at Leaf's buy a diagnostic app called Leaf Spy (about $30.00) and well worth it which will tell much more about the cars condition than the dealers.
The plan for now is to use grid power until I can get the solar set up to charge the car and I am not looking at a traditional off grid solar charger, I want to charge the car as I do my house batteries directly from the panels.
Most know me, never satisfied with the status quo.

The picture is of my very own "Odd Couple"...the Vic and the Leaf....total opposites and the Metro now residing in its private shelter.

I would love to do the same. Let us know how it goes.

I'm in Silicon Valley and see a lot of electric cars, and a fair number of people with grid tie solar and car chargers. Have not heard a single complaint about any elec car brand. But 'range anxiety' and charge times are still issues.

So now they have the hydrogen cars. Toyota Mirai and others. Not many filling stations yet, but the cars go far between fillups and fill quickly. For these reasons perhaps they will replace the electrics.

You can make your own hydrogen with solar or grid electricity. There is plenty of existing hydrogen generation technology out there already, but not much scaled to the residential user. But it should work fine- making hydrogen is easy, and storing it in standard gas bottles works fine. The hydrogen production can be timed to daylight hours when the solar is producing. There are a few manufacturers offering this kind of thing but it isn't in mass production yet like solar panels and inverters.

Could be that such hydrogen production will replace off-grid batteries. Once you have the stored hydrogen, all you need is a fuel cel to make electricity. Might need one or two batteries to handle initial loads before the fuel cel kicks in, but basically you would have as much wattage available to you as your fuel cel could produce and your hydrogen storage permits. And no worries about damaging batteries by drawing down the charge too much.

Congrats.

You should be able to tie your solar with Enphase inverters directly into a subpanel before your 240 charger. The power will go direct to the batteries.

Good luck.

The only drawback I have found going directly panel to car is all charging has to be done in daylight hours.

Kinda off topic but that's what I do....

So I saw a review of the latest (4th gen) electric Smart Fortwo. It's not yet available in North America. Then I read that starting 2018 (I believe ) all smarts will be electric. No more fossil fuel smarts.

Only 100 mile radius so it's definitely a city car that's always plugged in when not in use.

Mercedes is also negotiating with their union. The largest engine plant is being converted to electric motor and transmission mfctr. Seeing as the motors are so much simpler, what to do with that workforce?

G. I thought you were hooking up to the grid? So you can do net-metering? Put it in during the day, take it back at night.

Or charge during the day.

Battery backup is another option with a bimodel inverter. That's what i'm building now. But net-metering is cheaper.

Things took a turn today for grid power, the L&I inspector was supposed to check the power box for safety and he said the entire power system need to be brought up to current code.
long story short, I will again be investing that money into myself rather than PSE and will be looking to move ahead with the solar car charger.

groingo, will they not sell you the 220V car charger set up? Or not able to wire it in? If you have 220V service, can you wire it yourself? I know they can charge with a 110VAC charger too, just takes twice as long.

Back in the late 90's, Toyota made and sold electric RAV's, but only in California. Some guy on Hawaii wanted one, must have had plenty of $$$, he buys a home in California, buys the all electric RAV4 and has the charger professionally wired into his Cally home, then proceeds to remove it, shipped the RAV4 and the charger set up to Hawaii and sells the house.

Toyota has a special Prius called the Prius Prime, its super high tech, AC system itself is a heat pump, it used the GPS to learn your route to work and will calculate in your braking to figure in total charging.

Interesting that Toyota is not making any all electric vehicles now, from what I gather. They have a full range of hybrids, and plug in hybrids, but the plug ins only go 25 miles electric only. Perhaps they are banking on hydrogen development. Here's some progress in home hydrogen generation, which could work off grid in tandem with solar to fill your tank with H made from H2O-
