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:Need help with Solar Panels (FAQ's and opinions)?
You need a plan as to what you are going to with 80 watts of power. 80w at the best, it will usually be less. One problem I have is the limited specs, you don't even know the voltage. And you get a Sharp Module but nothing else is mentioned about it. I wouldn't buy it unless you can get full specs on it and on the Sharp Module. With no specs, it's difficult to get a refund if it is defective. If you are going to store it and use it for an AC appliance, a small one, you will need: a charge controller (to control the charge into the battery) a lead acid battery (to store energy for when the sun is out) an inverter (to convert 2 volts DC into 20 VAC) and all of these cost. .
Q:when building a solar panel should the diode be on the positive or negative side?
the blocking diode goes on the positive side
Q:how much does solar panels cost for you home?
Although its costs have been going down a little, solar power is still pretty expensive. To power a home you are looking at at between $8000 to $20,000 dollars (it will eventually pay for itself). There are systems that tie into the existing local power supply so that you have the city's power for back up (note: most power companies will buy electricty from you if you make more than you use). Then, of course, there are stand alone systems that operate without anyother power source (these are best for use in a place where electric lines aren't available or practical).
Q:Questions about the okorder.com solar panels?
I believe Earth4Energy to be a bald-faced scam, selling plans that will not do what is implied in the marketing, and imparting no information that is not publicly available on the internet, already. If you were to search for solar panel on torrent sites, most likely, some disgruntled customer has posted the material. It probably violates the E4E copyright, so I'm not suggesting that you get it in this manner. I'm going to skip many of your questions, given my already-stated opinion of Earth4Energy. Professionally-installed panels have a net cost of thousands of dollars in general. While they can save money (and Southern Cal is an ideal place for this), consider that it generally takes 0 years or more to get your money back. If you're on S Cal Edison, or SD Gas and Electric, you can go on net metering. They don't really pay you, they credit your electric bill. After a year, if you used more electricity than you generated, you pay them. If you generated more than you used, they reset the balance to zero and say thanks for your donation. You never really get a check, like in some other states. But you should have lower electric bills. You can put up panels for your own use without any certification. To put up panels professionally, you'll need a C-0 contractor's license from the state, or will need to be under the supervision of someone with such a license. But if it's the latter, you might just be the grunt that carries the panels off the truck and up the ladder, for minimum wage. I'd say better than 95% of residentail solar is connected to the grid, if the grid is available. It's a clear winner. Who wants to pay 50% more for their system, just to have batteries that need their water and acid checked all the time? Below is one of many unsatisfied customers from Earth4Energy. Be careful in your search, people selling these reports have bought up the keywords such as scam and ripoff to direct you back to sites selling the product.
Q:solar panel, dc light help?
3 w for 2 hours/night is 36 watt hours. You'll get about 500 watt hours/day from your panel on the average, which for a 2 volt battery is about 40 ampere hours. You can get an 80 amp-hour sealed gel cell battery to charge with this panel (with a suitable charge controller). You want to size your lights so the battery can provide three days of light without discharging it more than 50%, so that's abnout 600 watt-hours/3/36 = about 4 orf 5 lights. Cost for this system woulkd be over $500. The advantage of the self contained light is they use a lithium or nickel battery rather than a lead acid, so it can run totally dead without damage (unmlike a sealed lead-acid battery). That would be a far cheaper way to go. DK
Q:Solar panels require big initial investment, how can I check if the money I save will be more than that?
Only by doing the calculations (figuring out how much you electricity bill is per month now and calculate how much time it will take to get to the figure of your solar panels. Don't forget to add a couple of percentage points per year higher(since when has electrical costs gone down)? and do the addition. That is when you will pay off the solar panels, as their power is free.
