Looking at Solar: questions

[sdingeldein]

Hi, I've started looking at solar installation at my house. Everyone quotes me putting in two Tesla batteries with the solar panels and other items. The batteries are expensive. I hate the idea of having my lightning and not using the truck to power things since it is equivalent, I'm told, to about 7 Tesla batteries. In NC, however, Duke Energy has a 9,000 payment to allow them to suck off the batteries periodically.

I'm wondering if the same deal exists for the truck? When I bought the Ford charger Duke Energy gave me $1200 with the idea that if set up, the could use energy as needed.

I know the Sun Run system sucks (too bad) and am afraid of putting that in and integrating it with the solar set up. Any updates on how the status of SunRun installations are these days?

How about using a transfer switch with a system that has one Tesla battery (that gets the $9000 and $52/month from Duke Energy). Can there be a mix where the system uses both the Tesla battery and the car battery (via transfer) at the same time?

Thanks in advance.

I think you're going to find that this 'option' you mention, to use the truck's battery, or to charge the truck's battery via solar, is not only an investment in a massive amount of solar, but also not an 'easy' integration, as a permanent-mount battery system would be... many of us have priced and calculated the requirements for solar charging of a huge LIGHTNING battery pack, and may have come to the conclusion that it just does not make feasible, or financial, 'cents'... if you will.

now, if you live totally off grid, then you have no other options other than to try to design 'some' method of charging - although, even then, it's an uphill battle.

There is no V2G vehicle to grid option for the Lightning. Fords software is proprietary and there aren't any 3rd party systems that can function with the lightnings battery. Fords own HIS barely works for most people

Yet. Ford is testing V2G with several utilities.

Do we know which utilities? Duke Energy?

Duke pays you to be able to use your power during times of peak demand. Since you can’t guarantee the truck will be home and connected when that occurs, they don’t (currently) include vehicles in such a program. At least that’s my understanding.

Powerwall 3 is really the best way to go if you are grid tied. The Duke battery deal is a good one. Lightning is really only useful during an outage at this point. Tesla Powershare will be a better option when its more widely available. Contact Jesse with NCsolarnow. Their quotes and service were some of the best I got.

A Google search shows you. And yes, Duke is one.

Also, PG&E in California. I think there are 1 or 2 others.

I'll give you an example of charging a Lariat ER with just solar. Our offgrid place has 6.2kw of solar panels. This is in South/Central Montana with great sun exposure. I charge the truck at 8 amps (240v) when our solar batteries get above 90%. When our batteries get to 100% I might charge the truck at 16 amps for maybe an hour. 16 amps is the max charge I can do with our setup.

We usually arrive at our place with the truck between 30% - 50% SOC. Takes a few days before we are up to 80%. In the winter probably four or five days. Bought an older Grand Cherokee to leave up there as having a Lightning offgrid isn't practical unless you have massive amount of solar and stacked inverters. The closest fast charger is over an hour away.
