I’m planning to construct a solar powered ventilator. I have several questions.
If I use just one 12v dc solar panel (PV Module), how many fans( CPU Fan) can I operate?
Do i need a battery and a charge controller?
What about DC input?
How do I set up the system with the basic equipment to operate this solar powered ventilator project of mine?

Tips and links to other websites are are very much appreciated. Thank you for sharing your knowledge.

P/S: I am not an electrician neither an engineer in any engineering field. I just want to learn and invent something for the sake of inventing only.

If you want to power the fans only when solar energy is produce, the solution is rather simple, the sum of the load current should be a bit less than the current the panel can provide.

I believe a typical 80mm CPU fan draws 150ma, which is about 1.8W (I’d round that to 2W), and leave extra, so a 5 watt panel should run two fans easy.

If you want to run the fans all the time, in addition for accounting for powering the fans needed when solar is present, you need to account solar power needed to charge a battery at least enough to power when solar is not present in the one day, if not to cover a couple days with weak solar (such as overcast days). For that, you need a battery with enough capacity for those "non solar" conditions, and panel capacity to run your load and charge the battery. You will likely need a charge controller depending on capacity.

Very general answer. What you plan is difficult if you want to make it perfect. If you want to make it quick and dirty for fun, it could be a neat project.

A CPU fan is a great little thing to power because it is very well balanced and takes little energy.

Try to get some data on the fan. I am just guessing, but it is bound to be much less than 5 V DC.

If you want to play around, get some rechargeable batteries. See how many batteries, hooked in series, it takes you to power the fans. The fan has a little cable. One lead is positive and one negative. You might find that from 4 rechargeable batteries, you can run one to four fans for some period of time. Try a parallel configuration and see what happens.

Use the solar panel to charge the batteries. Use the batteries to power the fans. The reason is that the fans will then always spin at their usual rate, and they can spin even in the dark.

Get a good sense of what is positve and what is negative on your batteries and leads. Be careful not to mess up your panel by using positve and negative incorrectly.

Good luck.

I just got an estimate of about $37,000, and that was after rebates and tax credits. And I would still have a sizeable PG&E bill. And would it save to install yourself?

You know I bought 3 small security lights that run on light and they did not work so I am holding off on the big system. Plus PG&E is so expensive compaired to other companies.

Home made solar panels are quite easy to make these days considering the low cost of the components. They’re basically the heart of your solar power system that can drastically reduce the cost of electricity. The number of people that install solar panels in their houses is growing pretty fast due to these hard economical times and I am sure you’re looking to build such a system that can reduce your energy bills by 80% or even more.

The solar panels basically transform the solar energy into electricity. Buying ready made solar panels can be quite expensive and there’s a low return on investment. The cheapest solar panels are sold for $2000 or even more and that is why you would be better learning how to build your own solar panel and save hundreds that you can use for other home improvements.

We’re now building our fifth 200 W solar panel that will supply enough energy to light up two bedrooms. Read on to get an overview of how simple it is to build your own homemade solar power supply and what exactly you will need to get it installed properly.

For everybody that doesn’t know the main parts you need to build a solar panel are: plywood, copper, glass, wire, solder, silicone and UV protector and of course the solar cells or photovoltaic cells that basically capture the solar energ and transform it into green electricity. Solar cells are nearly half of your investment, they can be found at any solar parts shop or they can be order online at the lowest cost. Apart from all the component you’ll also need a solid guide in order to start your DIY project and accomplish it successfully without getting any headaches.

We personally followed the Earth 4 Energy guide simply because it’s a real blueprint that can teach even a DIY novice where to get the cheapest components and how to make a homemade solar panel with ease.

Do you ever look in the mirror and not recognize yourself? When your spacing off as you stare out the window of the car,bus,train, do you ever stop and wonder why you feel so alone though your surrounded by people? Do you ever get so frustrated because you haven’t found the answers to questions such as: What else is there outside of our solar system? Is it really just an ongoing amount of black space or is there more? Is God real? Or is he just something we make ourselves believe in to save ourselves from insanity? Deep down you know no one can truthfully answer those questions. Sure, you might hear some great explanations but how do they know? Where did they get their answer from? Do you ever brainwash yourself accidentally on purpose? Like, when making an important choice, as you analyze it subconsciously, do you knowingly "trick" yourself to make the choice you know is wrong? But you make it anyway. Your completely aware of the fact that its wrong but you peer pressured yourself by some unseen force. Do you ever catch yourself making expressions during a movie? When a character stares quizzically, do you feel your eyebrows furrow into confusion with them? Do you ever act like someone is watching you? Change tiny things about yourself as if to impress an invisible pair of judgmental eyes in the corners of your house? Such as sitting up straighter, slightly puckering your lips to add some sort of sexual appeal, etc. For what reason you do these things when your completely alone, you have not a clue.

Well, I do all of these things. How about you?
Feel free to tell other things you do besides the above mentioned.

i feel the need to bow down to you.
you have described exactly how i think and how my mind works. you should write a book on things like these. i was in shock reading this entire thing. wow.

Also, i feel there are two voices in my head (dont think im crazy) theres my conscience and my own voice. my conscience knows what my own voice is going to say before i say it in my head, yet i still say it anyways, and i some how know this.. it confuses me at times.

The energy cost is increasing day by day and simultaneously the cost of electricity is also increasing. The energy resources are also getting scarce day by day and therefore its time for the people to understand about the uses of the renewable energy resources. Energy of sun and wind are renewable sources of energy which can be used for number of purposes. The energy from the sun if used with the solar panel can help you to bring down your electricity bill to zero and therefore reduce the dependence on the fossil fuels.
Make your own solar panel
You can easily get the solar panels in the market which are made up of silicone of high quality. Why to spend hundreds or thousands of dollars if you can make your own solar panel? Making solar panel is not at all difficult job. In order to build a working solar panel all you need is a little effort, simple materials like electric stove, solar cells, copper wire, plastic or glass container of wide mouth, a multi-meter, copper sheet etc.
Before you start building a solar panel select or identify a place in your garden, roof or backyard where the sun rays are received the most. Solar cells should receive at least 6 hours of direct sunlight to work effectively.
A solar cell can easily make a solar power panel. This is how you can make your own solar panel. Place the solar cells or stack the solar cells horizontally and connect these cells which each other. After connecting the solar cells start of with cutting the sheet of copper which can match the size of the electric stove you have purchased. Clean the copper sheet with the help of sand paper as it will eliminate any traces of sulphide. Then start the electric stove to the maximum till the copper sheet changes its colour and becomes a thick layer of black coat. Then slowly and steadily make efforts to cool the copper sheet and the stove. When you cool off the copper sheet you will find the layer of red cuprous oxide on the sheet. After this process join the red cuprous copper sheet with a clean copper sheet using the alligator clips and put it into a plastic or glass contained which has a wide mouth making sure that they do not get in touch with other and fill the container with saltwater leaving the clips dry. Ensure that you connect the red cuprous sheet with the negative terminal. Then connect the solar panel to a battery or inventor.That is how you make your own solar panel.
The sun light is captured by the solar collector which focuses the sun light energy into solar cells which then converts the sun light into electricity.
