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.

We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.

3. How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

4. Can you do OEM for us?

Yes, we can.

5. How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The perfect time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.

Q: The voltage and power problems of solar panels
From morning to night (with sunshine) solar panel voltage is generally relatively stable, that is basically about 30V; but the output power is always changing, sooner or later, noon; if it is good quality solar energy,
Q: I've seen a couple homes around my town that have solar power and I live in the Desert, where the sun is shinning and it gets really hot during the summer. We run our air conditioner a lot making our electricity bill high.So I just wanted to know if anyone has or knows anyone that has solar panels? are they worth getting and is it the same as having electricity?
and, if given the tax credits, you'll see a faster return on investment in CA than I would have in Western PA (I was given a 0 year return number without factoring any tax credits). Plus you'll be doing something good for the environment. My brother put his house for sale which had solar panels for hot water, and was offered good money for the solar panels independent of selling the house. If anyone has a any no answer that doesn't involve the initial expense, I'm looking forward to reading it.
Q: how much would you pay for a 2'x4' solar panel that puts out 24 volts and 74 watts?
That's a rather low power for that size. Is it an old panel? Is it amorphous silicon, or crystalline? That should easily fetch $ per watt on craigslist. If I was buying a panel myself, I would probably get a more mainstream panel from a major internet vendor.
Q: What is the difference between solar panels and light panels?
The highest conversion efficiency in the laboratory is 24.7%, and the efficiency of the scale is 16%. Polysilicon conversion rate of 14% -15%. Amorphous silicon conversion rate of 12%. Silicon film conversion rate of 9%. Silicon solar cell is the main raw material of silicon, silicon is an extremely rich element of the earth, almost everywhere there are silicon, can be said to be inexhaustible, with silicon to create solar cells, raw materials can be described as no shortage.
Q: I live in Sacramento, CA, and I need some solar panels for a project fo school. They don't have to be very big......just something that I can use as an example.Thanks!
Trees, they have plenty of leaves. You'll probably have to buy an educational kit from Radio Shack or something like that. Maybe break some old solar powered calculators open.
Q: Hi. I have been looking into getting solar panals but I only want them for one room. See, we're expanding the house by adding a basement, the basement isn't going to be that big but we wanted to have solar energy for the basement only. Could anyone give me a rough estimate on the cost of solar panals for my basement?
If you're really planning on solar energy, don't waste it on your own consumption. The Hydro company pays you for the energy you put back into the grid....the strange thing is, you buy the power back for less than you sold it, so you actually profit on the power you make! look into this. I wired a nice house for a doctor, and although I didnt supply the solar system, I learned of this concept there. The guy who installed her system charged her around $40,000.00 and the system would never be able to run any large portion of their home. They, of course sold the energy to the utility.
Q: Do solar panels require regular inspections?
Yes, solar panels do require regular inspections to ensure optimal performance and identify any potential issues or maintenance needs.
Q: I am building a solar car for the energy wiz competition and I was wondering how I could possibly get my solar panel to shift sideways
having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
Q: i need technical and non technical details to generate MW power by solar panels
Sorry if I don't have all the specifics you asked for, but Sun Power makes the most efficient solar panels on the market, at close to 20% efficiency. They have made cells with up to 25% efficiency in the lab. That doesn't make it the cheapest but means the most watts per square foot. Thin film panels are cheaper to make but not as efficient. They are about half as efficient as conventional silicon panels. First Solar makes the cheapest per watt right now. So I guess that makes them the actuall cheapest manufacturer. They are able to make them cheap enough to beat out the conventional silicon panels on a per watt basis, despite being less efficient. A company called NanoSolar has the price down close to First Solar's price. These are manufacturers. But they do installations and build utility and commercial scale projects. NanoSolar is less far along in commercialization. They have products, but probably need to wait for the stock market to be more favorable for IPOs, so they can go public and raise the money to move up to scale. The other two are already public.
Q: i have a fountain system that has a small electric pump. its made to be close to a house but i want it across the driveway and i dont want to run electrical over there.is there a small solar panel that i can get fairly inexpensive to mount on a nearby tree and be able to plug the pump into it?
More okorder /... (... or search portable solar panel) And probably under a tree isn't a good placement for a solar panel. Good luck!
