If our cells are found not in conformity to the specification of manufacturer, or should the inspected quantity found in shortage, or should the packing found damaged, the buyer has the right to claim to the seller. The claim, if any, should be presented to seller within 30 days after cargo's arrival date to the port, together with related inspection report and photos issued and provided by a reputable independent surveyor such as SGS.

3). World’s Leading Manufacturer Equipment. We imported the newest and leading production equipment from abroad. Advanced equipment can guarantee the stable quality of cells. Auto production line can also save labor cost which will further cut our production cost.

4). Bulk supply: With the production capacity of 500MW, we can produce large quantity every month. This can satisfy most customer requirement.

 

3.Usage and Applications of Poly Cells

Solar cells are often electrically connected and encapsulated as a module.

Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage.

Connecting cells in parallel will yield a higher current;our solar cells have passed IEC Certification.

With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

Q:What is the anatomy of a solar panel?
You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
Q:Where can I get damaged solar panels?
Test the battery. Connect the positive and negative terminals of the battery to the positive and negative probes of the voltmeter. If a voltage is read, the battery is still good. Remember, however, that this is a rechargeable battery, so if it is dead, it can be recharged.
Q:Solar panel experiment ?
Acciona of Spain is actively conducting research in all sorts of alternative energy. I understand they have an experimental solar farm someplace in the desert southwest of the U.S. that is made up of 283,000 panels. I don't know the size of the panels or anything else about the project other than that. 50 years ago it would have been the U.S. conducting leading research in solar energy-especially in the U.S. Southwest.
Q:Solar Panel Question...?
Nice enough idea you have there, but practical reality is waiting to bring you back to your senses. The appliances you want to operate take a lot of power. You would need an awful lot of solar cells or a very cumbersome windmill to provide sufficient energy for them. You will find that for a mobile kitchen, an ordinary generator running on gasoline or diesel will be much less expensive to buy and maintain, less trouble to haul around, and much easier to replace if necessary. Considering that propane will probably prove less expensive yet, go with that for as many appliances as possible.
Q:Im looking at getting solar panels.
I recenty had a system installed for my home, you can get a system that will dramatically reduce your over all electric bill for $20K. My system which is currently running my meter backwards from about 8:30 am till about 6pm cost me around $8K, I did get a $0K rebate and I'll get a $2K federal tax credit. I just had the system installed this week, so I won't know how much it will take away from my yearly consumption for a while. I personally think an overall system is a beter financial option. If you get one that just runs your a/c then you lose the benifit of the energy it is producing when the a/c isn't running. It makes sense to have a system to run an item that is located away from a source of electricity, but then you would need to invest in a storage system. The best advice, is to have a contractor come out and give you a quote. You can get a system that will produce part of your electricity all year and you can always add to it at a later time to eleminate your electric bill.
Q:Has anyone had roof problems caused by rooftop solar panels?
Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
Q:Why did the voltage of a solar panel drop significantly after putting it through a step down voltage regulator?
you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
Q:where do you get little solar panels?
Thin-film solar panels are a great way to go if you're looking for small solar panels. Thin-film have the advantage of being lighter while a traditional crystalline panel is more efficient so it can produce more power with the same area. With the increasing efficiency of thin-film solar panels, however, they are quickly becoming an excellent option for portable power solutions. If you want crystalline panels instead of thin-film, the DURAlite line is a good example of a portable solar panel that uses regular polycrystalline solar cells. DURAlite panels come in 5, 0, or 20 Watts and they have a 0' cable with a 2-volt car-style socket plug.
