Ev vehicles sask

Noticed in Maui, solar collectors on most of the houses. Sunshine all year👍

Not covered with snow that you have to climb up on the roof to clear?

EV car manufacturers are already designing some EVs to provide backup power for homes in case of a power outage. So given enough EV batteries attached to the grid this could also provide some of the backup for intermittent generation sources. How this will all shakeout in the future is still unknown. The naysayers will always say it can't work for various reasons. But technological innovation and progress continues regardless. As fossil energy prices rise other options become more viable.

honk! honk!

So now we are back to where we started. You want to rely on the rest of the grid for cheap storage. Works fine when there are a handful of electric cars, and very few solar panels.

Now extrapolate that up to even 20% market penetration of EVs, and solar panels, and see how much solar power you can sell back to the grid, and what it costs to buy it back after the sun goes down. Let alone 100% as is being promoted.
Time of day metering along with excess solar will make solar power mostly a liability unless you have your own storage.

I can't blame you early adopters for enjoying the free ride being generously provided by The rest of us.

Surplus solar already happened in California and lots more to come because new start ups are easy to capitalize due to tax holidays and virtuous investors.
Doesn't have to make sense long term as promoters cash in on the share sales. Like penny stock mining scams.

Yes it's a FREE RIDE. How is the depreciation on EV's? about double ICE I am seeing. After X years a new battery will be needed, ridiculous $$ upgrade.

So there are a few ways you could tackle this. You could sell all your day time production back to the grid (lets say 10cents/kWh for easy math). Sell 40kWh to the grid and you could charge 20kWh (generated kWh are paid @ market value, consumed kWh have transmission costs/admin fees/etc) at night for breakeven. Instead of investing in battery you just add more solar.

You could get 2 power walls so you can charge at night and sell the surplus to the grid.

Be sure to put a lid on Mt St. Helens.

A roof mounted solar array cant even power the home itself let alone a tesla or power wall.

Lets start talking facts and physics here.

Solar panels have been stuck in the low teens efficiency rate for 40 yrs. The only way a mass EV penetration works in urban areas with the grid and generation we have is if you agree to drive it 2 days a week.

If we decide that we need to power the homes, heat and our transportation with renewables or hydro our nukes, you better get started now. It takes more than 10 yrs to permit these projects and will require billions upon billions of barrels of crude oil to develop.

Lets leave the house off for a moment, assume we only want charge the EVs at home and the grid handles the rest. That means every home owner will need to invest $20-30K in a solar array that takes 10 yrs to pay itself off just to charge a $100k car. I shouldnt even have to calculate the economics on that one. Its a bust. A money losing depreciating exercise in virtue signal.

Just admit you like toys and leave it there.

So in order to run an EV you need to spend an additional $20,000 or do to set up a solar / charging station at home ??

This whole thing is simply a push to grab your energy dollar one way or the other , fossil fuels or electric and has very little to do with the environment at all , never has been . It’s about the flow of money .
All on the premises that your either saving the planet or killing it

Tell me about the fuel and maintenance costs for running an ICE vehicle over 5 years @ 30,000km/year.
