Specification of Solar Monocrystalline  Series

- Optimal permutation on solar cells to keep enough heat diffusion, decreases hot spot effect.
- High quality and anti-ageing EVA, weather resistance backside raw materials assure reliable solar panels.
- Passed 5400Pa mechanical loads testing by UL, can withstand bad and high mechanical load working environment.
- With good sealed performance, moisture resistant, aging resistance, high/low temperature resistant, the inner terminals of our junction box owns good electrical performance transmission. Bypass diodes used can avoide hot spot effect and damages to panels. Output cables and mating connectors are safe and reliable for installation application. Adopt weather resistance, sealed, good sticky silica gel when assembling.

RELIABILITY

- Tests by independent laboratories prove that Yingli Solar modules:

 Fully conform to certifi cation and regulatory standards.

 Withstand wind loads of up to 2.4kPa and snow loads of up to 5.4kPa, confi rming mechanical stability.

 Successfully endure ammonia and salt-mist exposure at the highest severity level, ensuring their performance in adverse conditions.

- Manufacturing facility certifi ed by TÜV Rheinland to ISO 9001:2008, ISO 14001:2004 and BS OHSAS 18001:2007.

Q:How much power does the solar panel produce?
Area is 4' * 2' * (0.3048m/ft)^2 = 0.743m^2. Incoming solar (assuming optimally oriented panel) averages about kW/m^2, so 743W max gross. 4% efficiency yields 300W. Most panels are about 0% - 5% efficient, which is about W. In either case, figure about /2 the theoretical efficiency for about 2 hrs per day. so, you can run something from 50 to 50W about 2hrs per day. Too small for any appliance except maybe a laptop or light bulb. Panels typically make about 2V, not enough to run household stuff anyway. Normally panels are used to charge batteries, then an inverter takes power from the battery to run your appliances. Good luck!
Q:How to connect 2 power supplies together? (Solar panels)?
Huh? you should have got something, in full sun, you should have gotten 3 or 4 volts, but milliamps in current. By connecting them pos. to pos., neg to neg,(paralell) it increases the current output. If you connect pos, on one, to neg. on the other, and measure between the remaining pos, and neg. you should have twice the voltage (series). You need 4 volts, but 4 AA's in series is 6 volts. If your going to use the panels to charge the batteries, you'll need a diode in series to prevent discharge during dark conditions, which the LED will work for.
Q:background of solar panel?
Photovoltaic cells work because of the photoelectric effect. However, a solar panel can actually be using several different technologies that have the same common effect of generating electricity when the sun shines on them.
Q:Single Solar Panel savings?
No matter what or how you do it it is best to get off coal and nukes. So it cost a little bit of money you are buying 30 years of electric. How much will you spend adding in cost of living increases over the next 30 years? Solar really is pretty cheap if you take the time to do the long term math. If you use your cost at to days rates it does seem like a lot. But if you do the math like in real life with 3.5% compounded cost of living increases per year and 6.5% fuel increases per year. Well, you pay a lot more renting power. One other thing to think about and Al Gore keeps pointing it out is, Will your off spring be alive in 50 years from now if you don't buy the solar panel? Kind of like not going to the doctor because you can't afford the bill. Well I would rather owe a bill to a doctor that I will have trouble paying then not be alive at all to try. If you don't have the money to jump in and go full blown Green you should buy a starter system. You can get a system that can be expanded to 3000 watts (enough to power an energy efficient home). Would cost you about $8000 USD to get started and then you could add three solar modules at a time till you get it up to the 3000 watt max. And even have backup power. Or you could just buy a 000 watt system for about the same price and just add 3 of them over the years. There are many ways to get started. The deal is everyone needs to get started even if it is a small system. If all 50 million homes in the USA would install a small 000 watt system with 4 hours of sun light a day. We would provide (000 watts times 4 hours times 365 days times 50 million homes) 29,000,000,000,000 watts not from coal or nuke plants per year. I wonder if that would help?
Q:Why don't we design a wind-turbine with solar-panels on it?
Good to know someone is thinking and coming up with original ideas, so thanks for contributing... Put a large powerful solar collector on the end of the turbine too i.e. facing the sky! Far as I know, solar works on day-light (doesn't have to face the sun). So your idea is not to be put down. Metal blade turbines - are heavy - wooden windmills - heavy... so some added weight to the wind-turbine's paddles would be OK robably. Great if solar device not made of glass (so unbreakable). I think panels on the roof are old hat...
Q:What is the main material for making solar panels?
You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.

Q:Solar Panel Question...?
The best way to find out is to determine the wattage of each piece of equipment you want to use and how many hours you want to use those pieces of equipment. Finally, calculate the total number of Watt-Hours you need at minimum. Then you need to research solar panels or mobile wind mills (they need to be pretty huge to get a decent amount of energy I think, so solar power is probably the way to go). You will need to figure out the efficiency of the solar panels, the size of the array, how you will turn it or if you will turn it at all (to face the sun to get the maximum energy input, or maybe to use mirrors so you don't have to turn it. Once you find a good configuration for your mobile kitchen, you need to calculate if the Watt-Hours you will generate on an average day (with average weather) is enough to power the equipment whose energy requirements you previously calculated. Then you have to keep in mind that some days will have no sun, and you may not be working on some days, but you can still capture sunlight. For each case, a large battery array will be required. If you had a guage on that array, you could also hook it up to the a small generator in case you need immediate power. It's an eco-friendly process, but the initial cost is high and it requires a lot of research and planning. This is why most people do not do it--not because they don't want free energy from the sun, but because it's not easy to start collecting that energy in an efficient way. Sorry I couldn't give you more specific numbers, but a solar panel sales agency should be able to estimate whether or not you could do it (they'd probably set it all up for you too). ^_^
Q:QUestion about portable Solar Panels.. Mine is 2v?
Like others have reported, the voltage may well be 2v, however the amperage is approximately .0 amps Thats the capability of photograph voltaic. relatives shops are monsterously greater useful. yet, the voltage is there, and the amperage is there, including that's- so, that photograph voltaic panel might desire to cost up a monetary business enterprise of four 2v batteries under pressure jointly in parallel.... it in simple terms could take approximately 3 weeks. it can be a great trickle cost. I play around with little 6v photograph voltaic cells, and in case you choose to work out it artwork, positioned a huge can capacitor around the photograph voltaic cellular leads for a minute or 2, then touch the capacitor to the motor leads... it is going to turn- proving the capability is actual. you in simple terms desire the Capacitor to save it up for slightly. interior the tip all of us have been given spoiled on the quite extreme performace capability of plug in electrical energy and chemical cellular batteries. Given the designed capability of those, any option source of capability is confident to be disappointing.
