Your Questions About Solar Powered Generator

Richard asks…

How can I make a cheap portable solar powered generator?

I need to know about the parts needed to make a solar power generator and also the instruction on how to make it?

HI… REALLY A VERY GOOD QUESTION…..

Using parts easily available from your local stores, you can make a small solar power generator for $250 to $300. Great for power failures and life outside the power grid. Power your computer, modem, vcr, tv, cameras, lights, or DC appliances anywhere you go. Use in cabins, boats, tents, archaeological digs, or while travelling throughout the third world. Have one in the office store room in case of power failures in your highrise. I keep mine in my bedroom where it powers my cd player, turntable, lights, modem, laptop, and (ahem) a back massager. I run a line out the window to an 8″ x 24″ panel on the roof.

1. Buy yourself a small solar panel. For about $100 you should be able to get one rated at 12 volts or better (look for 16 volts) at an RV or marine supplies store.

2. Buy yourself a battery. Get any size deep cycle 12 volt lead/acid or gel battery. You need the deep cycle battery for continuous use. The kind in your car is a cranking battery–just for starting an engine. Look for bargains, it should cost about $50-60.

3. Get a battery box to put it in for $10. (This is good for covering up the exposed terminals in case there are children about If you going to install the system in a pump shed, cabin, or boat, skip this.)

3. Buy a 12 volt DC meter. Radio Shack has them for about $25.

4. Buy a DC input. I like the triple inlet model which you can find at a car parts store in the cigarette lighter parts section for about $10. This is enough to power DC appliances, and there are many commercially available, like fans, one-pint water boilers, lights, hair dryers, baby bottle warmers, and vacuum cleaners. Many cassette players, answering machines, and other electrical appliances are DC already and with the right cable will run straight off the box.

5. But if you want to run AC appliances, you will have to invest in an inverter. This will convert the stored DC power in the battery into AC power for most of your household appliances. I bought a 115 volt 140 watt inverter made by Power-to-Go at Pep Boys for $50. More powerful inverters are available by mail. Count up the number of watts you'll be using (e.g., a small color television(=60 watts) with a VCR(=22 watts), you'll need 82 watts).

6. Use a drill to attach the meter and DC input to the top of the box.

7. Use insulated wire to attach the meter to the wingnut terminals on the battery. Connect the negative (-) pole first. Only handle one wire at a time. Connect the DC inlet to the battery in the same way. Connect the solar panel to the battery in the same way

8. Close the lid (I use a bungee cord to keep it tight). Put the solar panel in the sun. It takes 5-8 hours to charge a dead battery; 1-3 hours to top off a weak one. It will run radios, fans, and small wattage lights all night, or give you about 5 hours of continuous use at 115 volt AC, or about an hour boiling water. This system may be added on to with larger panels, inverters, and batteries.
Options: A pop-up circuit breaker may be added between the positive treminal and the volt meter. Some of you will want an ampmeter as well. The panels I recommend have built-in bypass diodes, but I recommend charge controllers for people who have panels without diodes. Another option is a voltage regulator, which is not necessary for a system this small, but a larger system would require one.

Mandy asks…

Would a solar powered microwave generator warm the planet?

Assume that the albedo of the solar panel is equal to the albedo of the surrounding land, and that the generator is not a blackbody, so that 100% of its power output falls within the microwave band.

Will this device warm the planet more than if it did not exist at all? Or would the visible light converted into electricity by the solar panel equally and exactly offset the energy contribution to the atmosphere from the microwaves, thus keeping total energy (and thus temperature) constant?

ssadmin answers:

Wouldn't make any difference.
Most of the microwave energy would be lost in space.
Reflected light is also lost.

There was a pretty good weather channel special that pointed out that 95% of solar heating is absorbed by the oceans.
That's why it's not generally visible outside your front door.
It's also why solutions that address the ocean are far more important.

Ken asks…

Could a solar powered UV generator completely reverse AGW?

A follow-up to my last question about microwave generators.

If we had a solar powered device capable of producing radiation only in the UVB band, and it were directed straight up, would this cause the stratosphere to heat due to the higher concentration of ozone there?

And if so, then since the device is solar powered and is essentially ‘stealing' energy from the sun that would have otherwise gone into warming the surface, it will have the effect of redistributing solar energy from the surface to the stratosphere.

So if enough of these devices are built on a large enough scale, would that “rebalance” the energy imbalance caused by global warming (where the upper atmosphere is cooling and lower atmosphere is warming) and eventually bring both tropospheric and stratospheric temperatures back to preindustrial levels, even without worrying about CO2?

Don't worry about practicality, I am just wondering if the physics add up or if there's some key piece I'm missing.

ssadmin answers:

Since the oceans are absorbing 95% of the energy, i don't think so.

Clearly if you could cover 1/2 the oceans with mirrors, you'd be able to reverse global warming.
But you'd create an environmental disaster in the process.
We've already reduced fish stocks to critical levels in much of the ocean.
Depriving the remaining ocean of sunlight would reduce algae and all of the fish that depend on it.

So the 2 problems are,
1. Scale, it really is not scalable to the size needed, and
2. Location, it doesn't lend itself to being deployed where the problem is most serious.

William asks…

how can you make a wind powered generator with solar panels as back up?

I am in the process of building a wind powered generator and I want to put on some solar panels on it as a back up source of energy. So pleas HELP!!!!!!

ssadmin answers:

Hi, This is a good question and I have your answer, This is a very simple thing to do you can buy all your materials in any store as simple as using a 6″ PVC Tube to make the blades for your wind generator. E-bay has a lot of DC Generators that are good to use as a wind generator. I bought a guide named earth4energy and they show how to make a wind generator in 3 simple steps. You can find this guide at : www.greenproductsolutionpr.com and also a lot of information about renewable energy.

Steps to make a wind generator :

Definitions:

Generator:
This wind turbine transforms wind power into electricity, with the use of an A DC Motor that generates the power to spin the blades,
Options include:
? Electric lawn mower motors that have been recycled.
? All motors made by Ametek.
? Alternators with a permanent magnet (car alternators).

In order to find a DC motor you can check eBay, or look for inexpensive power tools. Drills, screwdrivers and other tools are a great way to find inexpensive DC motors although they do not generate much energy they are great for smaller projects. A great DC motor/generator is the Ametek 30VDC as pictured below. I purchased this DC motor for about $50 from ebay.

Blades:

building PVC blades from an old pipe please watch our instruction video from the members page.
? Acquire a 6-inch wide, 24-inch long PVC pipe.
? Quarter the piece of pipe around its circumference, cutting it lengthwise into four pieces (diagram on the next page).

This is only a preview of the step-step guide that they include in their package for more information please visit : www.greenproductsolutionpr.com

I can share with you more information because is a copyright information

Maria asks…

How does the electric generator powered by solar power works?

How does it work and what are the benefits and consequences from it?

ssadmin answers:

Just like the way you light bulbs work, just in reverse
