2.Advantages of Poly Solar Cells

1). Tire-1 Solar Cells’ Manufacturer Quality Guarantee. With a complete and sophisticated quality government system, our Quality Management have arrived world’s leading place. Customer can receive Tire-1 Cells Maker’s Quality Standard Products.

2). Trusted Warranty. We can supply trusted after-sales service to our customer. 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:A good brand of solar panels for my house?
Mitsubishi panels have served us well for 3 years so far, no problems. Kyocera had a well-known problem many years ago, but they lived up to the warranty and replaced defective panels. Their current products are considred good. I like the value delivered by Suntech panels. Might be a best buy - shop around. I have not heard about any of the major brands having trouble, lately. If you're intending to connect to the grid, be cautious about used or blemished panels. While they might work fine, they usually are ineligible for rebates.
Q:Are solar panels a good idea in Seattle Wa?
The solar rating of your area is Good so I wouldnt see the reason not to use it. In my area solar rating is very good I get all evergy from it plus even selling it. My payback time was very quick but... If you are not in a hurry or cant afford to spend a lot, wait till end of the next year when the new flexible panels are coming to the market. They are suppose to be a lot cheaper, enviromental friendly more effective than the ones on the market now. Check out MY Estimator. I think for USA users its the best help on the net. You'll see your costs, tax incentives can get info about local PRO's aswell. Often people are shy to ask quotes but solar is overpriced at the moment so spend your time finding the best deals. Also check where panels are made, their efficency; warranty is usually 20 to 25years. Surf the net- OKorder, OKorder then check companies who sell solar panels. Some even offer price fix if you see other place selling with better price. Good luck!
Q:If I shine different color lights (bulbs) on a solar panel, will it affect the electricity output?
Q:Buying inverter for a solar panel?
I'm guessing that each of those solar cells is just 0.5 volt at max power, so if you make a 2-inch square panel, you will get 2 volts - not enough for the inverter. A car inverter is notoriously inefficient, but it would work if you connect it to a 2-volt battery. You cannot generally connect such an inverter to solar panels alone. The battery supplies the peak current that the inverter needs, and the panel charges the battery. To charge a 2-volt battery, you will want 36 cells, generally, which give you an 8-volt panel. You can buy an inexpensive charge controller somewhere. If your laptop will run off 2 volts directly, you can skip the inverter and be much more efficient. Or if the laptop runs of (say) 9 volts, you can use about 40 cells to get 20 volts, get the proper power plug from Radio Shack, and plug the panel directly into the laptop.
Q:Electricity question about solar panels?
No, not enough power. Energetic got some of it. A transformer will not convert DC to AC. Transformers work on AC. A power inverter converts. Your solar panels do only put out the 95W but at the higher impedence of the heater, at 24V it would only be able to push through about 45W. Less than an average light bulb in a desk lamp.
Q:How to Compare Solar Panels?
Every okorder.com for links and faq's.
Q:How much does it cost a factory to make a solar panel?
I think it will cost about %0 Million US for a 50 Mega Watt Factory
Q:Generator for solar panels....?
Well the sun don't shine at night does it. Nor much on cloudy days. You either need a generator or a whole lot of batteries. The batteries are a pain to maintain, they're expensive to install and they have to be replaced periodically. Generator's probably a decent alternative. I'm sure most people just stay on the grid for their backup. Even better if you live in an area where you're allowed to sell back excess capacity. If you're looking to spend this kind of money anyway you could look at a household fuel cell that runs on natural gas. Awesome technology, though if you buy the unit all prebuilt and ready to go it's going to run you like 50,000 bucks.
Q:How may solar panels/wind turbines may be made affordable?
Answered okorder.com/. They were initally so lame (and this is related to their general paranoia) that they cut deals to place the turbines before they secured corridor access to substations. Load gun, cock it, aim at foot, shoot.
Q:How big of a solar panel system would I need to get ?
