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:how much energy does a kilowatt solar panel produce in a year? (average)
Also you can look for INSOLATION TABLES on the Internet. Keep in mind, though, that the useful output of a solar system that produces AC will be somewhat less than the theoretical value. Local conditions, orientation of the modules, dust on modules, wire resistance losses and efficiency of inverters will drag down the true output. My 6 kW system produces just over 4 kW at optimum sun height.
Q:I was watching an idiot abroad, and I saw a family that lived in tent like huts, with no plumbing. And they had a solar panel, now if they can afford it, I know I can. Where do you get cheap ones?
I okorder Hope this helps.
Q:Can solar panels be installed on a hospital or medical facility?
Yes, solar panels can be installed on a hospital or medical facility. Solar panels can help hospitals and medical facilities reduce their electricity costs and reliance on the grid, while also promoting clean and sustainable energy.
Q:Can solar panels be used in areas with high levels of wildlife activity?
Yes, solar panels can be used in areas with high levels of wildlife activity. With proper planning and installation, solar panels can coexist with wildlife without causing harm. Techniques such as considering panel placement, using wildlife-friendly designs, and incorporating protective measures can help minimize any potential negative impacts on wildlife.
Q:There is a charge controller that has what i believe to be only port for a solar/ wind turbine control panel and i don't know if it has more than port for panels. So would i be abed to link 2 panels to port or do you think the controller has more than portBTW it is for marine use.
It will not hurt the panels to hook multiple ones in parallel (all red or positive wires together, and all black or negative wires together), and connect it to the single port on your charge controller. The more alike the two panels are, the better this will work. With two absolutely identical panels, you should get twice the power. With mismatched panels, somewhat less. This arrangement will not hurt the charge controller, either. The worst that happens is that the controller isn't able to take full advantage of all the power available. By the way, it's not advisable to connect both solar and wind together.
Q:Can solar panels be installed on a deck or patio?
Yes, solar panels can be installed on a deck or patio. In fact, these areas can often be ideal locations for solar panel installations as they are typically unobstructed by shade and have ample sunlight exposure. Additionally, installing solar panels on a deck or patio can help maximize the use of available space and may provide an aesthetically pleasing solution for homeowners. However, it is important to consult with a professional to determine the feasibility and structural integrity of the deck or patio for supporting the weight of the panels.
Q:I remember hearing somewhere that solar panels may attract light rays away from plants thus having a potentially negative effect on the plants. I can't remember where I heard it but I'm curious if there is any truth to it.
solar panels don't literary attract light but when the light hits it it turns into stored energy planets dont give of heat or ray if u mean stars like the sun yes. it doesn't have anything to do with planets its star noble gases that stuff u can steal light it just gets it other than wasting it solar panels are better than those factory thingys
Q:Can I add reflectors or mirrors around the solar panels to increase the power they generate?
You could (an example of concentrating sunlight is called cloud gain, where the edge of a cloud will intensify sunlight as it passes between the sun and your panels), but that will make your panels run hotter and will probably reduce their life. It's better from a system design standpoint to simply get another panel or two. DK
Q:I want to be more green and if I get the panels will I still have a regular electric bill?
The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array isn't producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. The best thing is to contact a professional installer to get a quote based on your location and electrical usage. Solar electric does not make financial sense in all areas. Our array cost $2,000 but don't use that as a guide. Yours might be 0 times that, or half that, depending on your area and needs.
Q:Let's say I can buy solar panels for my business for $5,000 and my payback period is 8 years. Would it be correct to assume that my money is best spent elsewhere (such as paying down debt) if I am being charged an interest rate of 3.9%?
I've done some research in this category, and I came to the conclusion that solar panels are simply too expensive to utilize effectively (at least for me). I was looking into buying them for my house, but I realized how expensive it would be and how little it would help. Maybe for a business it is more reasonable to do, I'm not sure. Either way I wish you luck in your decision, make sure you do your homework and find out everything you can before you go out and buy them. Personally I think if you have a lot of debt, you should try to start paying it down and get it done with. That is just my opinion, I have been studying businesses and economics for years and I believe that the strongest companies have strong balance sheets.
