How can we bring solar power energy to our streets?

I was having a debate with my friend about ways to make the environment better and to have a better energy reliance than oil. One idea that was floated was to have every street lamp based on solar power (with backup electrical grid power in case it rains or something) anyway, here was the debate which we need your answers to: Is it better to have a solar panel on each street light OR Is it better to keep the street lights as they are and just install solar panel hubs around the city that feeds into the electrical grid?

What are the properties of Solar Panels?

Properties of solar panel?
I know this is too general,but i am to write a report on the materials used to make solar panels,and i am to include the physical, mechanical ,and chemical properties of the materials.
It’s just too general,such that i am lost.There are so many types of solar panels.So i hope some experts on this subject can give me a general guide lines ,maybe the tensile strength ?
as much as you can please.
Why would i ask when i can find the answers on wikipedia???

What is the most cost-effective place to buy large solar electric panels?

We don’t have enough money right now to buy capacity for the whole house, which would probably require about 12 kilowatts. However, I would like to start buying panels toward building up toward that.

But I want to buy the most solar panel for the least price. I think that piecing a lot of very small panels together will be a very expensive way to do it.

Does anyone know the least expensive way to buy large solar electric panels?

How can I use Solar Power in my home?

I am wanting to power just a couple household items with a small solar panel. What will I need? I know I need a solar panel, and some kind of AC-DC converter, and a battery perhaps? How would I wire it up?

I do NOT want to spend a fortune doing this, I am only in an apartment, so it needs to be small and self-contained.

Thanks!

How can I power a couple small appliances using solar power?

What would I need to power a small fan, some LED lights, etc in my home, without spending hundreds or thousands of dollars? How would I set it up? I think I would need a Solar Panel, a AC/DC converter or some kind, and a Battery?

Any Help! Thanks!

How can electrons keep being generated by solar panels?

I was trying to figure out how solar panels work today and I found that electrons get displaced in 2 layers of a solar panel by photons coming from the sun to create power. If the electrons come from the solar panel and go into the electrical grid, how are they replaced in the solar panel? Wouldn’t the solar panel eventually lose all of its electrons and stop working? Electrons have mass, so wouldn’t the solar panel slowly deteriorate?

I think solar energy is awesome and I really want to know how it works. Any help in enlightening me on this subject would great, thanks!

Solar Power And It’s Costs

This is an ongoing discussion about solar power and the costs associated with implementing it as an energy source.

I have heard a lot about solar panels and I want to know how these solar panels works and is it really possible to generate electricity using solar panels. And what is the cost of getting a solar panel installed?

Solar Panel and Motor – Regulating Power Consumption

Here is a great question from one of our readers.

I’m an engineering student and for an individual hobby-like project i purchased a small solar panel and a small solar motor. I am planning on making a small solar powered toy car. The question I have is: is there a way to connect a control or some other ways of regulating the power that is absorbed by the cells? Other wise the motor will just continue to run. Any answer would be greatly appreciated. Thanks!
