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.

6.FAQ

1. What’s price per watt?

A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.

2. Can you tell me the parameter of your solar cells?

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:Where is the best place to get an education/experience and job in the installation of solar panels? ?
The best suggestion I can give is to call solar installation companies in your area, and ask for their recommendation as to what to do. They may recommend a technical college with an appropriate program. With unemployment rising, new jobs in solar will likely be scarce for a while. You might also inquire at roofing companies. If you apply at a solar company, and can demonstrate that you already have roofing experience, that will be a plus.
Q:How many and what size solar panels would I need?
Solar okorder.com in their survival discussion in the archive, this exact project was discussed at length.
Q:how much money can I make a year for the electricy I sell from a solar panel?
Ultimately it depends on your utility and the country you're in. In countries like Germany, Spain and the UK, the utilities will pay a higher price for the power you produce then what they sell it to you at. Otherwise, in countries that don't have such arrangements, net metering is best where what you produce is discounted from the amount you buy per month therefore so long as you produce less than you use, you get the full retail rate, otherwise you may get only half the retail rate with some utilities. Obviously, the solar panels are rated and won't produce much more than the rated power, a 4 foot by 2 foot panel would usually be rated at 00 watts but in most situations will produce about 80 watts and would probably cost about $500 US installed. If you assume 8 hours of usable sunshine a day, 70% sunny days, a 25 year service life, monthly billing and 0 cents a kilo watt hour retail rate, you can expect at most a -.67% per annum return on your investment, that's a negative sign out front. Basically without any subsidies, you will lose money on the panel, sure you're get some money every month, about $.34 per month for that 00 watt panel but it won't make back it's money at at a rate of 0.0 per kwh. With subsidies it might be a good investment but it's still not a good deal without subsidies.
Q:Mono-crystalline or poly-crystalline solar panel?
All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
Q:solar panel regulator?
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:Can I made my own solar panel?
If you're thinking of solar electric, unfortunately, it's not cost-effective to make your own panel. Be especially wary of scams like Earth4Energy that claim you can do it cheaply and effectively. If it was so easy, you'd see at least a few people in your neighborhood doing it.
Q:Does a solar panel work on a cloudy day or a rainy day?
A PV array produces electricity whenever the sun shines on it. This is true from sunrise until sunset, and often times even after the sun sets! (A full moon on a clear night can actually produce small amounts of current from a PV system.) Generally speaking, an array will produce its maximum power between roughly 9:00am and 3:00pm.
Q:Solar Energy Panels, a good idea?
Yes, but it is still very expensive at the moment. Look into solar leasing where you rent your roof to a company that installs and owns the panels and pays you a portion for surplus energy beyond your usage. I looked into going off the grid a couple years ago and based on our usual consumption it was going to take a $40,000 investment with a 0 year payback for panels, inverter, and storage batteries.
