Solar power and electric cars?

Question

Answer these three questions, please:

When so solar panels generate power, day or night?

When do people usually charge the batteries of their electric cars, day or night?

Since cars charge at night and solar power comes in the day, where does the electricity that charges your car come from?

P.S. Another question you should ask yourself that goes along with this theme: When do you turn the lights on in your house?

I hope you see that the point of this question is to make people realize that solar power isn't all they thought it was. I already know the answers to these questions.

Answer 1

Your questions point to a real--but not insoluable problem. That being that we need a source of electric power for electric cars that DOESN'T depend on conventional--that is,mostly coal powered--electric generation.

There are a number of options. Being able to carge from solar panels located at ones workplace is one.

Another--we are getting much better and more cost-effective battery storage technology. We may well be able to store solar energy that can then be sued to charge cars (and run homes--at night.

The key isn't being able to do this--that's easy. The tough part is to figure out how to do it cost-effictively. But don't dismiss these--or a number of other ideas that are being worked on..

But--your "questions" are a great capsule summary of the problem--nice post!

Answer 2

You're argument is flawed because you're not asking the most important, most basic question. When is electricity consumption highest?

Daytime, when it's used to run factories, light office buildings, and run heating, ventilation and air conditioning systems (HVAC) for office buildings. When people are awake. The difference between day/night electricity needs is quite large.

This electric company will sell electricity to customers at night for about 1/5 (!) of the daytime rate.

So, if you put solar cells on your house, you generate your own electricity when it's most in demand. If you have an excess during the day you can even help the power company when they need it most. Then they supply you electricity at night, when they have an excess. If the company offers time of day pricing, like the one above, you win even more.

Everybody wins. Solar power works better than you think.

Answer 3

Day

Night

Batteries in the garage?

P.S. Night. But the vast majority of my electric use is for air conditioning. And that is during the day. If solar panels were cheaper it would be a perfect use for them. Or if there were solar panels at the parking lot at work, you could charge cars with them there. Riiighhtt?

Answer 4

in the day solar means sun not moon other wise it would be lunar panels eh the power to recharge cars comes from the surplus that is gained through the day ie one would calculate how mch power one needs then purchase that much.
If you have solar you can leave them on.

Answer 5

by using fact the quantity of image voltaic panels or wind turbines required to capability a vehicle could be so super the vehicle does not much greater healthful on the roadways. One image voltaic panel this is approximately 4ft. X 3ft. purely produces approximately one hundred Watts in finished image voltaic. To capability a vehicle demands possibly one hundred HORSEPOWER. one hundred HP is like seventy 5,000 watts (750 image voltaic panels) additionally the wind does not continuously blow and the sunlight does not continuously shine.

Answer 7

1. day

2. night, so that they can use it in the day.

3. generators?

4. when it's dark enough and the mosquitoes are bitting you like hell.
