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:Solar Panels, kw per hour or day ?
kW is the unit of measurement used. kWh means you have kW steady for an entire hour. In the case of solar panels, say you are using 00W panels. That means at any given time assuming ample sunlight is hitting the panel, it is producing 00W. You wanted a kW so you will need ten panels at 00W (less or more depending on the rating of the panel) this will give you kW. That means at any given time you can get as many watts as needed up to kW (000W). Say the sun hits the panels for eight hours a day, you will have kWh each of those eight hours, or 8kWh per day. Unless you have a system of batteries to capture unused power, you will only be able to use up to kW (000W) at any given time, any unused power will be wasted. Solar panels alone are not like a generator, they do not slow down or speed up depending on demand. Even with no load on them, they will produce as much power as they are able, and without batteries that power is lost. To simply answer your question, if you get a kW system, that means kW per hour.
Q:Anyone have or know someone who has solar panels installed in their home? Is it worth getting?
Our neighbor has solar paneling, and he absolutely LOVES it! It is pretty much the same as having electricity, just better for the environment, and your electricity bill goes down to only about $7 a month!
Q:What are solar panels? what do they do?
Solar panels are, well panels that take solar energy from the sun, and use it as heat or electricity. It is used for many things but depending on the power of the sun and the panel, they can be used for trains,houses to heat them but you need a lot of sun, and they don't work without sun obviously.
Q:How to make electricity from the sun without using solar panels?
There are a couple other methods under development. One uses a fan inside a cooling tower and a large area covered with black tarps. The heated air can only escape through the cooling tower in the center of the site. The air movement turns the fan blades that spin a generator. Another solar generator uses mirrors that track the sun and focus their energy on a large pipe. I don't recall the contents of the pipe, but the superheated material is used to boil water generating steam to spin a turbine/generator. Neither of these are small scale projects, and are probably far more expensive than what you're looking for.
Q:How to install a solar panel system?
If you are grid-tied, then a standard solar electric system will always feed back into the grid if you are not utilizing more power in your home than is being generated by the solar panels and inverter system. It is possible that a grid isolation device designed to prevent direct back feeding is available, but haven't heard of one in common use. New laws in most areas of the US are now mandating that utilities allow grid-tied alternative energy systems. Double-check you local laws. Sometimes you can't take the utilities word for truth--most will automatically say 'no' and will only relent when you show up with the law in hand. Unfortunately, some utilities have figured out another way to shut down alternative energy pioneers--they demand multimillion dollar insurance policies covering damage that their equipment could sustain from your little PV system. Technically, they are still in compliance with the law, they just make it impossible for a homeowner to meet their requirements. If you are getting the runaround, go to your state representative for help. It's amazing how contrite those utility people can be when a state senator (or even US Senator) has just sent a letter asking them why they are stonewalling a law-abiding and well-meaning citizen. Good luck, and don't give up!
Q:Making a Charger out of small solar panels?
3-T is just one type of many devices designed to control voltage so you get the amount you desire with as little static as possible. Without you having an degree in engineering, I can't explain it to you any better. You will also need to produce true sine wave energy or you will burn out your PSP with the correct volts and amps. You need one to produce only 5 volts 2amps. Anything different will burn out yur PSP. Your problem is simple math. Watts = volts multiplied by amps. Amps = Watts divided by volts. So if your solar panels can produce /4 amp ( 250 mA) each, then you connect one to the other in a series until you get enough connected to make 2A. ( 8 panels { /4mA x 8 = 2A}) You now have a panel with 32Volts, 2Amps, 64 Watts. This is where the T-3 regulator comes in. If you buy one for 5 volts, it will allow only 5 volts 2 amps, to go to your PSP.
Q:Anyone who knows or has Solar Panels?
In my experience the snow usually slides off by itself. There have been times when it's snowed heavily and I've had to clean it off but it does not tend to be the norm.
Q:Please differentiate b/w mono & poly crystalline silicon solar panels.?
Guide okorder.com/
Q:What is the best solar panel?
You have to decide which is more important to you, cost or efficiency. The most efficient solar panels that are commercially available cost more than twice as much per square foot than the cheapest ones. Ultimately, I believe that the cost per watt was actually better on the cheaper, least efficient panels, but then you need a lot of square footage in order to generate any substantial power. So it comes down to what you have more of, space or money. The new panels that collect a wider range of light are not currently available commercially, and when they are I am sure that they will be expensive. I have read the research but have not heard of anyone mass producing them yet.
Q:SOLAR Panels?
Be glad you didn't buy. The current products are dinosaurs, 50 year old over priced tech. Don't lose hope though. The thin film tech is just now starting production. It's not yet available to the general public ( production for the next year is already sold out), but will be in the near future as production capacity increases. It should drop prices to about /4 of the current price, and your recoup time will be about 7 years. Go ahead and research thin film solar, and be thankful you didn't buy a product the government has to pay you to buy.
