Solar panel and motor: Any way to regulate the power transmission?

I assume it is a DC motor. You should have DC voltage coming out of the solar cell (For example 10V). You could use a transistor to switch the voltage on and off, then filter the output with an RC filter. You will have to choose the right RC time constant . It will have to be slower than the control pulse frequency, but faster than the desired motor response time. If you switched the voltage with a 50% duty cycle, then filtered the output, you would get 5V, with a 75% duty cycle, you would get 7.5V, etc. Therefore, you could control the motor by controlling the duty cycle of the switching. A microcontroller like the BASIC Stamp can produce the control pulses.

Could Solar Power work more effectively if the solar rays were magnified?

No, it would not. If the magnifying glass is the same area as the solar collectors, then it would be the same amount of energy the solar collectors would be gathering without the magnifying glass. In a way it would be cheaper, using cheap mirrors to focus the sun's rays onto a smaller solar collector surface area. And solar collectors are far more expensive. But as to more power? No.

How can I make my own solar panel and produce solar power electricity and green energy?

here's some useful info about solar panels, hope it helps.

How exactly do wind and solar power companies make their money?

Your question is fairly general. Perhaps you would like to read these introductory articles and then post more specific questions: ---------------------

How to get solar power continuously and without any interrupt?

"Only solar power is the guaranteed clean,affordable ,low prices alternative option." Clean? How are they manufactured? Affordable? Why don't we all have them? Placed above the clouds? Hmmmm.....would this increase the cost? Does it get dark above the clouds at night? Keep thinking! Check your facts, Mr. 357. Listen to "Dark Side of the Moon" by Pink Floyd. Especially the very end.

How many solar power towers are there in the world?

No body knows. New ones are being built all the time. There is no central data base that keeps track of such projects.

What kind of solar power setup would I need to power a single room's energy needs?

Let me just say, the cost would be too much to be worthwhile. It appears you would need at least 750 watts. if you wanted to use the electrical things at night too, the system would have to deliver that much power for the equipment, and more to charge the batteries. Make it a total of 1500 watts, and you would need between 10 and 15 panels, plus an inverter, mounting rails for the panels, two fused disconnect switches and wire. I expect around $10,000 or more.

Solar Power?

Solar power refers to the utilisation of the sunlight for meeting our energy needs, which are otherwise met by electricity or coal, oil, gas etc. There are several ways for utilising solar power: - photovoltaic cells for producing electricity (very expensive to set up but maintenance free) - solar water heaters very popular in several countries to produce hot water - solar cookers for cooking food Solar power is environmentally very clean - no carbon dioxide, no radiation, no health hazards etc. but it is very expensive right now.

solar power?

The question is not too clear, as solar chargers are in fact d/c power as is the batteries they charge. To get a/c power from the system you will need an "inverter", and they come in various sizes, watts that is. The amount of time will also depend on the batteries used, as they are all not the same. Reserve amps will be the determining factor to look at. There is a formula published by the makers of these inverters that will give approximate running times, and most can be found through Google under the manufacturers brand name.
