Got my weekly usage report. Apparently, I used the most electricity on a Monday. With peak usage at 3PM (During the work day) and also, apparently my home used ZERO electricity on Thursday of that week. Amazing!
The better designed ones do have regenerative braking, which does feed some bit of trickle charge back into the battery.Maybe they should put windmlls on top of those electric cars so they can charge while they drive?
All of my bills have shown a comparable energy usage to last year. My costs however, have doubled. I thought it was only a 25% increase?What surprised me is - my energy use for March was HALF what it was last year, and I am still paying more.

Maybe require the roof of the things be made of solar cells?

Yup, He's right. The amount of charge from solar cells on a car is almost nothing to help extend range.Cybertruck tonneu out of solar cells and he said you get maybe 5-6 miles a day with good sun.

However, solar cells on a car would help to maintain the 12 volt battery (like the cameras that are on 24/7) and maybe supplement the HVAC that needs to run to keep the computer cool while parked on a hot day.
Good luck. My only comment is that I repeatedly see horror stories from people using LiFePO4 batteries. When working they have great charging and discharging specs and seems to be the "goto" battery of choice, but the rate of failure is very high, even from reputable dealers. Most of the time it's an individual cell that fails, but it renders the entire battery useless. A LiFePO4 battery also requires a BMS (battery management system), a small circuit board in the battery. It also has a high problematic history, turns off unexpectedly, doesn't pass the current it's rated for.... again, rendering the battery useless.I'm working on the final details for an off-grid electric generation system for our island club. We're designing for a peak output of 25kw and an average of about 16kw. Going to require roughly 1000 square feet of solar panels and a lot of batteries...not settled on the total battery capacity yet. A 25kw diesel generator is part of the system, and will automatically start up if the battery capacity drops too low. I'll post updates once the design is finalized...in a separate thread. I'm learning a lot as this project progresses, knowledge that I hope to eventually put to use for our personal property.
We wanted to include a small 5kw (peak) wind turbine but discovered that a special permit is required for those around here due to Pax River air space restrictions. Which is total BS because the turbine we're considering isn't any taller than the damned trees nearby. Might fight that battle later on and still add a turbine or two.
The complete system has a very high-end overall power management system and inverters...over $8000 in total for all the do-dads and capability. We're stil debating the battery type though..your points being why its still under discussion. We have a guy working this project design that is more expert than I by far on these exact off-grid setups.Good luck.

Between cost and reliability, I'd stick with AGMs if you want a known expectancy with good availability and ability to recycle.
Can't you have SGI do it as collateral duty during the 15 minutes of lunch/break time you allow him per day?We have a guy working this project design that is more expert than I by far on these exact off-grid setups.
15-minute lunch break??? Shirley you jest....Can't you have SGI do it as collateral duty during the 15 minutes of lunch/break time you allow him per day?
Not sure how the electric grid would hold up if everyone switched to EV's.
