Q:What is the principle of solar panels work?
optical - electrical direct conversion method is the use of photoelectric effect, the solar radiation can be directly converted into electrical energy, optical - electrical conversion of the basic device is the solar cell. The solar cell is a device that converts solar energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode turns the solar energy into electricity. Current. When many batteries in series or in parallel can become a relatively large output power of the solar cell array
Q:Solar panel charging question?
Most solar panels have something called a charge controller on them. This prevents electricity from going backwards from the battery to the panel. Solar panels are rated at 2V but they do put out a little more than that during full sun operation. You didn't specify the size of your battery but it really doesn't matter. It comes down to your consumption of power. If you are only charging the RV battery so it maintains a charge when you don't use it very much, a 5 watt panel is fine. It will charge the battery and keep the small drains on the battery from making it go dead ( the clock radio, the theft deterrent system, etc use power even when RV is off) But if you are using the battery to run things when you are parked, you probably don't have a big enough panel. If you use a 30watt fluorescent light and a 00 watt laptop, you need 30 watts of power saved up every hour in your battery and that's with no inefficiencies. So if your panel puts out 5 watts an hour and you are using 30 watts an hour, you need 30 watts/ 5 watts = 9 hours minimum of charge time to run your stuff for just one hour. You probably need a panel of around a 00 watts to get any meaningful use of your battery. Plus, you never want to run your battery to full drain because it ruins the plates inside the battery. Watts = volts x amps. If you have 2 volts panels, you would charge at 8 amps with a 00 watt panel. This is a good charge rate. Any more than this and you risk warping the plates with too much heat.
Q:advice what solar panels to purchase?
If all things are equal buy local. If you are building for a LEED project then choose a manufacture within 500 miles. Another reason to choose a local panel is that if things go wrong there is a better chance of a satisfactory resolution. A no name knockoff from overseas might prove to be difficult to find a few years down the road. One good place to check is the Go Solar California website. They have proof of performance testing on hundreds of panels.
Q:The future of solar panels?
Solar Panel really isn't any new technology, it was discovered in the early 60s. And as you can see it hasn't progressed all that much. But Developers are saying that within the next five years solar technology will increase dramatically. With more and more people looking for greener and easier forms of energy, there are many looking towards solar. In fact some energy companies are willing to buy the energy that you produce from you. And with new forms of thinner silicon panels, we are looking at a more efficient kind of panels. Unfortunately for us, at the moment thin-film panel silicon isn't as efficient as we are looking for. They are flimsier than the traditional panels and do not contain as much silicon to produce the electricity. But as soon as the demand increases, the production will increase, and if more companies are looking to invest in solar, then there will be more competition, with more competition- we are going to have improved technology, and with more improved technology, the prices will go down. Because at the moment, there is not much of an incentive for solar power. Compared to the Kilowatt- hour produced from coal and other forms of energy, solar does not produce as much. Experts are saying that within the next five years, not having solar panels on your house will be as silly as building a house without plumbing. The future on solar panels looks bright.
Q:Self build solar panel ?
Lithium For USB power, there are some references you should seek out from the websites of Fairchild, On Semiconductor, Texas Instruments, National Semiconductor, just to name a few. There are others, and if your IPad has the control circuitry for the accurate charging of their batteries, and you just need the USB port to have the right power available, a high compliance regulator such as an LM7805 should do just fine. Spec sheets for that regulator are available through the above mentioned manufacturers websites as well.
Q:Im a bit confused about what a solar panel is?
As Aviophage says, there is plenty of info around. Solar panels produce electrical energy from the sunlight's energy. The sun puts out around 00W per square meter, and the panels are up to 20% efficient at converting this. If you are looking for a Grid Connected power system, they are usually made up of 24V modules about 50W each. The full voltage produced is then around 50V to 500V DC depending on the sun etc. They are connected to a specialised grid connect or grid interactive inverter (look up Sunny Boy for an example) which converts this to mains power for use around the house, while any remainder is exported to the supply network. The supply company may buy this at premium rates, and governments may provide subsidies to approved installations. There may also be carbon credit certificates when you buy a system. Not all places allow such things to be connected to the grid, but this market is rapidly changing. The links below should get you started.
Q:Where can i find a list of solar panel manufactures worldwide?
Actually Ofir, it is much easier and less expensive than you might believe. What you need is a magazine, like, Solar Today. There is only one that I am familiar with that gets into the nuts and bolts of solar panel manufacturers, installation, and other types of renewable energy. It's called, Home Power Magazine. We have a home that has been powered by the wind and sun for the last 0 years or so, and most of our initial information came from Home Power, and afterward, from many of the sources that they have in their articles. Every few issures, they take an item connected to renewable energy, such as an inverter, wind turbine, water turbine, or solar panel, and list all the different models that are available. They are broken down by manufacturer, and include specifications like power output, range of voltages, efficiency, materials, and even where they are manufactured. If you subscribe online for one year, the cost is around $25 USD, you will have access to all the previous issues that are archived on their website. You can use their search engine to locate an article listing all the solar panels, they did one a year or so ago with all the information you are looking for. Despite what you might be hearing, solar power usage is growing at an incredible rate. In the US alone, there are over 00,000 homes and businesses operating some level of solar power right now, that's good news. As far as different countries using different requirements, most all of the manufacturers today are selling their products to most countries worldwide, they are designed to meet requirements for almost anyplace you might use them. Check the magazine out today, you might learn more than you were originally looking for. I will include their link below, and some other good sources for information. You can google any one of them to find their website. Good luck, and take care...Rudydoo
Q:can i use 00 ohm /4 watt resister for 5v coming direct from solar panel?
Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.
Q:installing solar panels on roof?
Go This is the web site for the magazine Homepower. You should probably get a copy of the magazine and have a look (there is a Free Sample Issue botton on the site). It contains articles about real people and their solar collectors. It usually details what kind of system they have and provides an illustration of the different parts. These articles and illustrations are very helpful to people who are new to the topic. They also have articles on things are far ranging as the national electrical codes for solar electric panels, building your own electric car and solar ovens for cooking. Check the site out and then request a free magazine.
Q:Solar Panel costs and sizes?
Good question I am uncomfortable doing my child's homework so I will not complete the assignment for you. I am also always willing to help. Having the kWh is a great start. You must also ask the question when you size a system is there any way to reduce this load. Each kWh that you do not have to produce saves significant cost to the system. Next what type of system grid tied or off grid the two systems will have very different size needs and overall cost. I googled PV system sizing and got the below link. at first glance I like it. You can do the same for system cost. I also included a trade link for your review factors in sizing system type amount of bill offsetting geographic location site location track mounted or fixed and more Should you need additional help you can email me I will not do your work for you but I can either verify it or point you in the right direction
