How does solar power help the environment?

We Answered:

Most electricity today is created by burning coal or natural gas. This burning causes global warming and pollution. And huge complexes of wires criss cross our country.

If every home had solar power, we'd need fewer electrical generation plants. Thus less pollution and fewer wires carrying the power. Imagine a solar power panel on every house's roof. Each home might be able to generate electricity and hot water for their own needs. This avoids pollution, global warming, carbon dioxide emissions, etc.

Solar panels would probably involve plumbers, carpenters and electricians. Are these the kind of panels that have water in them? If so, plumbers would be needed...

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

We Answered:

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.

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

We Answered:

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.

How to generate solar power for the home?

We Answered:

Solar generators produce electricity using so-called solar cells or photovoltaic cells, which convert the energy of sunlight to electric energy by the photovoltaic effect. Solar panel is used to save your money once your fixed it to your home you will access that power to all your home appliances.. You have to buy solar panel setup along with inverter which going to invert the AC into DC power. For more details search in google..

How Can I Use Solar Power in My House?

We Answered:

install solar power panels its that easy !
This will heat your water, For energy you can install a wind generator but be warned this might anger neighbours who might not appreciate the noise of the fan rotating in the wind.

Gordon Said:

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

We Answered:

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.
