Better question is if you should. I'm not sure I would personally use the car as a $100k battery when you can get a $250 Anker or Ecoflow to do the same thing, with more outlets to boot.

Agree 100%. Well worth the investment to have available if the power goes out.

You can literally charge devices off any car that has a working 12v battery in it.
Also true about having a few battery packs. They're so cheap to buy now there's no reason to not have a couple of $20 or less battery packs. Hell, most brands of tools.offer inverters and other charging options for their batteries. |

Too bad it doesn’t have V2G (vehicle to grid) technology…that would allow you use the X5 50e to power your house with either the battery or engine (house would have to be wired appropriately)
That’s one benefit of EV/PHEV that is not being taken advantage of…there is a lot of power in that battery (and gas tank on on the 50e) that could be real useful during a power failure. |

That said, we also really don't lose power here often. They keep burying a y power lines that are on poles already, and in the 4 years we've been here we haven't lost power for more than a few seconds. If we were to lose power, it'd be from the big one of hurricanes, and you don't try to ride out the big one..a Cat3, a weak Cat4, sure. But when you start talking really strong Cat5s, then it's time to get out. |

The ROI of solar is a function of a few things: cost per kW for installation, NEM rule, cost per kWh from utility company. In Cali, even with the super expansive electricity, and under NEM2 1 to 1 upload, abundant solar time, the break even time for solar PV system is about 8 years if you size your system correctly. In your example, you have a electricity bill of $300/month, $3600/year. With $13k system, You break even time is 4 years. I wonder what is the cost of your electricity as well.

I also have dead south exposure, literally 180degree due south which definitely helps. I’ve heard 6-8 years as well, looks like I fell on the earlier side of that estimate.

A couple things.
Our prior house never had this issue. I assume b/c of buried lines. The new house has above ground line and Xcel does not maintain them at all. We have not once in the 3.5 years of owning this house seen them maintain the lines/trees. Our rear neighbor has trees growing all into it. I called Xcel out and they said there is nothing they can do b/c it's not on my property line. Which is BS, they have full access to the right of way. He just didn't want to be bothered b/c no one in CO has a work ethic. /rant This is now the second time in less than 2 years that we gone 24hours or more without power due to a big wet snow. We do have a couple of portable chargers. But haven't purchased a large power bank. Partly b/c we thought the last one may have been a fluke. Partly b/c we'll need a new roof in about 5 years and we're going solar when we replace it. I think this summer we're either going to look at installing a 10kwhr battery in anticipation of the eventual solar or go the cheaper route and get a Generac or even just a harbor freight generator and have the electrician put in a hook up/detach panel. Long story short didn't have to use the X5 but I am curious why some think it would be a bad idea. |

No, V2G is allowed and used in the US.

The real big drawback tomsolar here is homeowners insurance. Keeping a solar array on your roof with 200mph winds and them not becoming flying projectiles isn't super easy. |

It is a function of the racking system. When did mine, the permit require a rack that can sustain local wind rating. If done properly panel should not come off in local wind. Now in FL hurricanes, thr roof may come off tho.

In my case, Cali, effective sun hour is 1900/year, typical contractor solar installation cost per kW of $3.5, I need 8 years to break even.

We nearly built a house in a new development when we moved here. One of their shticks was they build the houses to be super efficient and they're all pre wired for solar. Of the 50ish houses in the development (it was tiny), last time we drove by there were none with solar arrays on their houses. It's a shame because honestly it's a great option for post hurricane power. It's almost always sunny after storms, so if you lost power and had solar+battery backup you could be powered up immediately after. It just isn't feasible yet, even with all the sun we get (which frankly, is probably less hours than you'd expect, we get a LOT of rain and storms here, and the sun we do get is super intense). |

I think one reason for FL people don’t put in solar is the cost of kWh from utility. If you pay $0.15/kWh, it will take the length of the panel life to break even. Then you would ask why bother. In my very own case, since I DIYed, thr cost for me is about 40% of typical contractors. Months of weekend work tho, I should break even in 4 years or so if pge don’t change rate structure.
