i have a homework project for n.s. we have to take one energy and convert it into another one any ideas would be helpful too?!
There’s a fabulous site that has lots of build it yourself solar projects. http://www.builditsolar.com/ This is not to be confused with those scam sites promising to power your house for $200, avoid those at all costs.
Build it Solar has projects for solar water heating that would be perfect for you.
http://www.EnergyBrainiac.com – How to Build Your Own Home Made Solar Panel to Generate Electricity
If you have ever considered constructing your own home made solar panel then we absolutely urge you to follow up and take action because we are more than confident that you will be glad that you did. We all know that the cost of electricity is quite expensive now and continues to rise so just imagine how great it would be if you could reduce or even eliminate your utility bills.
A solar panel is made of photovoltaic cells that are strung together to create a panel. When the sun’s rays shine on the cells energy in the form of heat is absorbed. It is that absorbed energy that is then converted into electricity. It really is a rather simple process but don’t let its simplicity fool you. Solar energy is a very powerful way to generate electricity.
Harnessing the rays of the sun provides a free and unlimited supply of energy. In addition to that, unlike fossil fuels that are not used to generate electricity, solar energy creates no pollution and therefore does not harm the environment in any way, shape or form.
While I dare say that the majority of homeowners would like to take advantage of solar power, the costs can be prohibitive. Preconstructed solar energy systems can be extremely expensive depending upon how involved they are. It is not at all uncommon for people to pay $20,000 or more to have commercially manufactured solar panels installed on their home.
Building your own home made solar panel on the other hand can be done for less than $200. Quite a difference in price isn’t it? Once more, there are no special skills required and the parts and tools necessary to construct your very own photovoltaic solar panel can be purchased at your local hardware store or home improvement center.
Time and again the people that take the initiative to build their own solar panels report that their electricity bills have been, at the very least, cut in half. It is also very possible to eliminate your electricity bill altogether. And if you are truly ambitious you can construct enough homemade solar panels that you can actually create a surplus of electricity that you can sell back to the utility company for a profit.
In addition to the savings you will see on your power bills, the IRS also allows a tax deduction for people that take advantage of alternative energy resources such as solar and wind power. Solar panels will also increase the resale value of your home. It truly is a win-win situation.
While the primary objective to constructing a home made solar panel is to save money on energy costs, an incredibly wonderful byproduct of using solar energy is that it is environmentally friendly. Solar energy is also known as green energy because it is not harmful to the environment and unlike fossil fuels that are currently used to generate electricity, it does not create any pollution.

it has to be homemade and i can’t buy anything
Well it depends on what your actually trying to do as the comment above says its pretty much impossible. Al tho u can make a cheaper homemade version like on this website:
http://www.treehugger.com/files/2008/09/how-to-make-diy-cheap-inexpensive-solar-panels-ebay.php
or if you want to create a way of using the sun to heat water you can do something similar create a long box pain the inside black then lay a painted black metal pipe up and down the box to maximize the length of the pipe in the box.
then simply put a glass top in it to help keep heet in and pump water through the pipe obviously having the box in the sun.
i need to make a mini-solar car which shouldn’t cost much. it’s for my science project. for now, i just found out how to make a solar panel using copper oxide, but it does not generate enough power to power up the engine of the toy car [ the small engine they used in the toys, like from TAMIA]
try adding more solar panels to your car, what if you take the solar panels out of 2 or 3 calulators , add them, then use some tiny mirrors to help draw more light into the panels,.——————————————————————————————————A solar cell (or a "photovoltaic" cell) is a device that converts photons from the sun (solar light) into electricity. In general, a solar cell that includes the capacity to capture both solar and nonsolar sources of light (such as photons from incandescent bulbs) is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics.
Solar cells have many applications. Historically solar cells have been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth orbiting satellites or space probes , consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water pumping applications. Recently solar cells are particularly used in assemblies of solar modules (photovoltaic arrays) connected to the electricity grid through an inverter, often in combination with a net metering arrangement.
Solar cells are regarded as one of the key technologies towards a sustainable energy supply.
(cont.) In One Day?
The approximate size will be 4 X 8 foot
It’s for a school project, so no need to be accurate.
And please don’t put stuff like "it all depends on where it is…" that crap.
thank you!!
it depends on several factors
figure about 25 square inch per watt
Anita
would someone please tell me how in a simple way how to make a solar panel please? ive searched but no luck.
put clear pipes which connect to your water supply in a box with a black matt surface and shiny under side on the roof.
the black matt helps absorb heat radiation
the shiny light surface helps reflect heat back inside the box.
it is probably very hard to make though and there are many places to buy them.
hope that helps =)

For school, I need to heat 2 lieters of water with a solar panel.
anyone know how to do this
Making a black plastic container with a large surface area will do it. I worked at an archaeology field camp out in the mountains one summer and we took hot showers every day by filling these things called "sun showers". They were black plastic 10-liter bags with a screw on lid at one end to fill it up and a hose with a clamp valve and spray head at the other. We would fill them every morning after breakfast and then lay them out in the sun. By supper time they would be over 100 degrees and we would each take one and hang it on a hook above us in a shower room we built out of boards and tarps and be able to take a nice long hot shower.
Here’s an article and photo of the bag:

This Yahoo Answers question and the subsequent response should give you an informed answer (linked below). Be sure to check out the link given, quite informative.
It boils down to the operating life of the solar panel, the efficiency of the solar panel and the energy needed for the manufacturing process, all of which vary for different manufacturers or technologies.
please help me on this. I am 17 year old boy and i don’t know so much about science.
please help me in simple(deeply) steps and things using in this.plz plz plz
thanks in advance.
This a quote:
"Materials you will need
The solar cell is made from these materials:
1.A sheet of copper flashing from the hardware store. This normally costs about $5.00 per square foot. We will need about half a square foot.
2.Two alligator clip leads.
3.A sensitive micro-ammeter that can read currents between 10 and 50 micro amperes. Radio Shack sells small LCD multimeters that will do, but I used a small surplus meter with a needle.
4.An electric stove. My kitchen stove is gas, so I bought a small one-burner electric hotplate for about $25. The little 700 watt burners probably won’t work — mine is 1100 watts, so the burner gets red hot.
5.A large clear plastic bottle off of which you can cut the top. I used a 2 liter spring water bottle. A large mouth glass jar will also work.
6.Table salt. We will want a couple tablespoons of salt.
7.Tap water.
8.Sand paper or a wire brush on an electric drill.
9.Sheet metal shears for cutting the copper sheet."
