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:how much money can I make a year for the electricy I sell from a solar panel?
call your power company and ask them how much they pay for each kWh you feed back into the grid (the price may vary for different times of the day). then multiply that by however much electricity you are producing.
Q:Are solar panels actually efficient?
They're more efficient than nothing, or fusion for that matter since fusion hasn't gone anywhere in the last 30 years. Since most energy is used during the day time when its light out solar panels will do pretty well. In most habbital places on the planet its light out for a good part of the day while wind doesn't blow steadily in most places.
Q:why aren't solar panels for your house more affordable?
It okorder.com to locate a solar specialist in your area. Be sure to ask them about any state or local tax incentives for installing home solar. This can really drop your costs.
Q:Solar Panel Question?
There are 720 hours in a month (30 days) but only about /2 of those are in *full* sun 800 kW hr / 360 hr = 5 kW. 5000 W / 65 W / panel = 30 panels minimum and that's based on full sun during the day (no clouds, rain, etc). Besides an inverter you'll also want a bank of batteries to operate at night. OR, you can get about 35 - 40 panels and sell power back to the utility during the day (meter runs backwards), and use power off the grid at night. Suprise! solar power isn't cheap, is it? Figure on taking advantage of some government and public utility rebates, though to lessen the cost. .
Q:How can I run my house purely off of solar panels?
In my opinion you can do it. You will need to have solar panels. and batteries to store the power until needed.
Q:What are your opinions on solar energy?
I have had my system for almost a year and love it. I got a 3.74 kwh/dc system, my highest electric bill was $35 in the dead of winter and last month was $6.. I paid $6K for the system and was told I would break even in my 6th year, that was factoring in a 5% annual rate increase. In my area the last few rate increased have been well over 5% and they are talking up to 2% next year. Just keep in mind the amount of energy you use will determine how large of a system will work best for you. My system is tied to the grid, so I don't need a storage system. My utility has net metering, so I sell them my excess during the day and buy back what I need at night.
Q:can a l.e.d light power a solar panel?
It could but the solar panel would produce much less energy then it took to light the LED.
Q:Reflectors or mirrors around the solar panels.......?
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:How to make electricity from the sun without using solar panels?
There are a couple other methods under development. One uses a fan inside a cooling tower and a large area covered with black tarps. The heated air can only escape through the cooling tower in the center of the site. The air movement turns the fan blades that spin a generator. Another solar generator uses mirrors that track the sun and focus their energy on a large pipe. I don't recall the contents of the pipe, but the superheated material is used to boil water generating steam to spin a turbine/generator. Neither of these are small scale projects, and are probably far more expensive than what you're looking for.
Q:Shouldn't 0bama increase our tax benefits for solar panels so we can buy more Chinese products?
Go ahead admit it...Carter was right ! He was right in seeking to raise the fleet auto mileage standard to 48 miles per gallon by 995. (Even U.S. automakers admitted at the time that they could easily achieve 30 mpg by 985.) Carter was right in exhorting Americans to turn down their thermostats, even if he did look nerdy in a cardigan while urging us to do so. He was right to encourage fuel conservation by proposing a 50-cents-per-gallon tax on gasoline and a fee on imported oil —- in effect, a floor for fuel prices. Invoking the pioneering spirit of the 960s moon mission, he was right to recommend a tax on windfall oil profits to finance a crash program to develop affordable synthetic fuels. Carter was correct, too, in setting a goal of obtaining 20 percent of our energy from solar power by the year 2000. The solar panels Carter put up on the Whitehouse were USA made. The solar
