1. Structure of Solar Panels 280w with Mono /Poly Silicon Material Description

Solar panel refers either to a photovoltaics (PV) module, a solar hot water panel, or to a set of solar photovoltaics modules electrically

 connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be

 used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Each

 module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a

 module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16%

efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only

 a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar

 modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q:how to make a solar panel?
All you need to do is to learn how to build solar panel to produce your own electrical energy through solar panels. These solar panels take and keep the energy from the sun and turn it into usable electrical energy that we can use every day in our ordinary lives. Generally, the majority of people that knew about solar panels think that they won't benefit from its use because they just work in sunny areas. That isn’t the case. In fact, the new generation of solar panels can produce a lot of electrical energy even on rainy weathers. Learning how to build solar panel is very easy: first they need to be installed (most of the time, on the roof of homes) and then they take the energy from the rays of sunshine and convert it from solar energy to electrical energy. Solar panels must be kept from shading, as shaded cells draw energy for themselves from other cells. Things you need to know: . Solar panels using monocrystalline cells have high conversion efficiency, and take up less space, but lack shade protection. 2. Solar panels using polycrystalline cells have even higher conversion efficiency, take up even less space, but still lack shade protection. 3. Solar panels using amorphous silicon cells have lower conversion efficiency, and take up more space, but do have shade protection. This can be especially important on a sailboat. Once you have determined the size and number of solar panels needed, you will be better able to determine where they will be placed. The best places depend on the roof's length and size of the panels. Take your time and think it through. The simple answer to how to build solar panel is none other than the sun. Select locations that will get maximum sunlight without shaded spots. In placing solar panels, consider the use of extra bars/braces to secure the panels. You obviously want them to remain stable.
Q:Research Paper on Solar Panels?
I'm a big fan of solar panels, and we even have an array on our house, but I would have a hard time supporting the thesis that solar panels are the best way to go green. Conservation and efficiency are. Using less is better than making more. If someone has the money for panels, but their house is poorly insulated, their money would be better spent on insulation. Pretty much anyone in the solar industry would agree. And solar hot water makes sense over a much wider geographical range than solar electric.
Q:Can you overload solar panels with too much light?
Solar panels have a upper temperature limit, and it's only a bit more than it would reach in a very bright sunny day near the equator. Start shining heat lamps on it and you will raise it past it's max temperature, and it will die. .
Q:Do solar panels go bad if not used?
Batteries can only be recharged so many times and as for panels going bad, only the weather will help break the metal down by rusting it away.
Q:question about Solar Panels?
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
Q:Solar panel connected to battery ??
You really need a little more infomation about your battery. It should have a recommended range of charging current. You should not exceed that range. Your solar cells must be a higher voltage than the battery, but you should not connect the cells directly to the battery. First, you need a diode in the line to keep the battery from draining into the solar cells when there is no light. Second, you need a resistor to limit the charging current. You have a 3.6v battery. Let's say the charging current is 0.A. Use a 5v solar cell and silicon diode. The diode will drop the cell voltage to 4.3v. The voltage across the resistor will be .7v for .A current, you need a 7-ohm resistor.
Q:Maintenance for solar panels....?
All panels should be cleaned to function best. Brush or wash off dirt and leaves. They should be checked for structural integrity and lack of rust. Solar Thermal panels should be checked for signs of leaks and/or discharge from pressure relief valves. Solar Photovoltaic should be checked for electrical function and grounding.
Q:solar panel for pool pump?
You can buy a solar pool pump with all the equipment you'll need.
Q:Improvising Solar Panel Made from Old CD or DVD? Possible or not?
A solar electric panel? No. Solar electric cells, or more properly photovoltiac (PV) cells, are made from specially prepared (doped) wafers of silicon, much like transistors and diodes. CDs and DVDs are made from plastic plated with aluminum. They don't have anything to do with each other. Of course you can make a reflector out of CDs or DVDs, and you could use a bunch of them to focus sunlight on a water tank or something - this is called solar thermal generation. (That's what that ehow page is talking about, not generating electricity.) But there are much better things to use for mirrors.
Q:how effective & efficient are home made solar panels?
I had a system installed recently, so I would suggest starting by getting a quote from a licensed contractor. Even if you are planning on doing the installation yourself, a contractor will have a lot of useful info. I got 3 quotes and they were all about the same cost. I was able to get a 2 year usage history from our utility so the contractors were able to suggest a system based on that. They were able to tell me about rebates and tax credits, were the best location would be and the estimated amount of production. They have a nifty gadget that can tell if there will be any shade cast on the roof at any time during the year. I decided to maximize my rebates and got a system that reduced my utility bill by about 50%, although my production has cut it much more than that, my highest electric bill was $35, and that was in Dec. with cloudy short days. I got a $0K rebate and a $2K tax credit. This year the fed. tax credit is 30% of the total installed price. My system cost $26K, I paid $6K out of pocket and I'm saving about $2K per year.
