Doesnt the battery wear out quicker when discharged more often? Im not sure with lithium batteries so I am actually curious.

Here's info as of 2013.https://phys.org/news/2013-04-life-lithium-ion-ba ... ctric.html

Some more good info on effect of use on battery life here.

We had to replace the battery in a laptop we only charged when it needed. Since then, we rarely use them without the power cord plugged in and they've lasted longer.

I'm on my second battery for my cell phone - and the one in it now won't hold a charge as long as when it was new.

Details, details Sunny....why think about logistics and real world applications and experience when the future is so bright? Just wait, my flying car is just around the corner......

There are plenty more varieties of different compounds that make up the lithium batteries...some a laptop will never see...
7000 cycles, but depth of discharge factors in.
Not so important for ppls laptops but can run your house.

Just returned from a week in Vermont and can attest to seeing a number of solar farms. While not pleasant to look at they are significantly better than windmills to look at, only see them when you drive up on them.

They are erecting a square mile of them a mile from me the next 2 years. I feel sorry for the people that will have to look at them out of their windows. One is a new home back off the road and will be surrounded. I have a feeling within 10 years they will be around me if they expand as the land around me is owned by one of the solar renters. Of course the landowners live elsewhere so arent affected by it, similar to confinement pig farms.

They are both eyesores but I guess at least the solar is quiet unlike windmills. Its really a tossup which one I'd rather have around but I wish that the towns that want them would build them in their own towns and leave me alone instead of cramming them down my throat to the benifit of people that dont even live near me.

Be nice if everyone that has to look at one out their window got free electricity. It would seem like the least they could do to maintain good relations but I am naive I guess.

Cant get free electricity because nothing is free....particularly energy.

My electric cost from West Penn Power is 5 cents per KWH. There are roughly $13 state tax and $14 distribution additional charges. West Penn Power no longer generates their own electric. I'm all for solar panels on my roof soon as I can afford them.

Let me know how the ROI works out and if you will live long enough to break even.

We're so lucky to have with us somebody that clearly has their finger on the pulse, so to speak!!!

This has been discussed many times over the years and anyone can calculate their electrical costs and then go look at how long that will take to recover, after all the necessary equipment and the hook up will cost. And so I did. The results range from its a no brainer or don't bother. If you live in New Mexico, or Hawaii, and you can do some of it yourself, might work..... if you go big enough to run the AC all day and night. It is also like Real Estate, location, location, location. When it is realistic, the usual people will be screaming from the rooftops.

Could it help maybe to have more efficient A/C and the like to help bridge that gap?

I will get that after I get my flying car.

Believe this is reason demand will decrease, higher efficiency appliances in use. Decades ago heat pumps were a Southern thing because they didn't work well at cold temps, today they are used in the North in equally.
