Ev vehicles sask

Why are they not built with solar panels on the roof or hood to continually charge??

Not enough area to really justify it on a car. There is a new one coming out called the Aptera that has built in solar charging for 40miles of range per day. The entire vehicle has the aerodynamic drag of a F-150 side mirror.

That's why any place that vehicles are parked for the day will have a solar installation. If you want to charge your EV with solar that was produced during the day you will need a home battery. When you put solar energy directly into an EV it has zero consequence to grid capacity. You are going from panel to battery and excluding the grid completely.

I have a couple of thoughts. First what do you think the cost of the home batterylarge enough to charge the EV will be? A Tesla power wall 2 stores 13.5 kwh of electricity. What is an average EV, 22 kwh storage and up? The cost of one power wall is $8-10 thousand Canadian, you would need 2. Then how many solar panels at $2 an installed watt, let’s say a 10 kwh system, another $20000. Yup charging the Tesla with solar is cheap. What will the cost be to employers to install solar powered charging stations, enough for all their workers? And who is the net beneficiary? China, 80% of the worlds solar panels are made in China and 75% of them made with coal fired electricity!

Personally I have no issue with EV’s. Personally if I bought one it would be a hybrid simply because of a longer range and 2 options for power. I do have an issue with EV subsidies as well as governments paying for the installation of charging stations. I also think solar power is fine when the sun shines but it is not a dependable 24 hour solution and environmentalists let on like it is, absolute lunacy imo.

Son is a GM tech, says ANY repairs on an EV must follow STRICT safety protocols, special gloves coveralls. An ISOLATED service bay, numerous DISCHARGE procedures. These batteries can KILL you. That will be CHEAP, lets double the per hour service costs.

2 power walls would be a lot. I guess a lot of it depends on how much you drive per day on average and how often your car is home during sunlight hours. My 3 year average on a model 3 is 178Wh/km with 90% highway driving (the most inefficient type for EV). In the city you can easily get 130-145Wh/km. 100km of highway driving would be 17.8kWh battery power and you would add charging losses (89%charge efficiency) to get a total of 20kWh. A 10KW system would charge 100km of driving in 2 hours @ 100% production or 4 hours at 50% production.

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 1 power wall and split the difference.

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

Depending on location, season, hardware, there are a ton of variables.

Sorry sir, our tech had to put on gloves so the service rate was $285/hour.

How many solar panals must you have to charge your car in 1 hour?

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

How many solar panals must you have to charge your car in 1 hour?

A lot. 250kw max charge rate for DC. Charge rate tapers as the battery fills but you’ll need 75kwh which works out to $20 of electricity. But why do I need to do a full charge in an hour? 95% of charging at home can be from 1kw-10kw. Fast charging is only for road trips.

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

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 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.

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.

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.

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.
