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:Solar panels for a small gym outside my house?
Yes you can.. Use it to charge a 2 volt battery then use the battery power to run a 2 volt halogen bulb. Would be much better to power some LED's with the battery -- just as much light but will last longer.
Q:What ever happened to solar powered panels?
they still make them,i have them on my camper to charge the batteries, they are not cheap, however. you can get them at r.v. supply stores. in fact the ones they make now, are quite efficient, many people in the countryside use them for their homes, i dont know why the development for cars is so slow, though.
Q:highest known watt output for solar panels?
Those two requests are somewhat at odds with each other. Trina and Suntech make panels that are generally good value. You can search the web and find your best price. If this is for something that does not need to last long, you could get amorphous panels and save some money. But they will degrade quickly in a few months, then slowly over a few years.
Q:thermodynamic question that includes heating water with solar panels?
Good points. I'm new to the solar energy world, but solar just makes sense. Who wouldn't want to make it work? The more I learn the more I think its a great alternative to some of the energy we use. This info really helps.
Q:How does a solar panel turn sunlight into electricity?
my theory is that when sunlight hits the panel it excites the electrons from the rays there by making them move more quckly and attract them to a source with less elctrons making the panel positiveli charge and the electron collector negatively charged thereby connecting the negatively charged particles to which ever body it wishes to donate it too thereby causing electric charges
Q:Powering an air conditioner via solar panels?
There's no need to connect only the A/C to solar, nor is there a need to use batteries. Both of those problems are solved with grid-tied solar. The solar electricity system works alongside your regular, and the A/C just plugs in normally. You never need to worry about switching. During the day, if the A/C is drawing power, the solar goes into that, reducing your draw from the electric company. If the solar generates more than the A/C needs, the meter is driven backwards. At night, the meter runs forward again. For example, the meter may read 5000 in the morning. By evening, maybe it reads 4975. At night, it creeps back up to 5005. When the meter reader comes, you would be billed for only 5 kWh. That's the general idea. Also, consider whether you can insulate your home more, and whether you might want to change out your air conditioners for new, DC inverter mini-split units. Those can use a fraction of the electricity per BTU of regular air conditioners.
Q:What direction do solar panels usually point?
I can't believe how many people posted wrong answers to this. Where are they looking? What are they thinking? In the northern hemisphere, solar panels are ALWAYS oriented due south. In the southern hemisphere, face them due north. I am typing on a computer that is running on a solar electric system that supplies my whole house. Been this way for years. So it works.
Q:i want to light up a building using solar panel what do i need?
The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
Q:How long does it take to charge a 2v deep cycle battery with a 0 watt solar panel?
What is the open circuit voltage and voltage under load with the panel in full sun? Assuming it is typical of many 0W panels, the open circuit voltage is 2V and the voltage under load is about 7V. 0W/7V is 588mA. A typical car battery is 40 Amp Hours. Amp Hours, or Ah, is the capacity of the battery. How much current a battery can delivery starting a car is called cold cranking amps. A deep cycle marine battery will typically be more than 40Ah. A 40Ah car battery at 50% charge will more than likely start your car in fair weather. Cold weather is another story. So, to get a completely dead car battery to 50% - 20Ah - would be maybe two days of full sunlight - with only a 50% charge, or about 2.2 Volts. Not a great battery charger - however - It makes a great supplement, and can offset the use of DC powered equipment in the vehicle while the engine is off. Things like low-wattage lights, cell phone chargers, tablets, and the like will drain the battery down that much slower. I have a number of powered but low current items on in my truck all the time. A panel helps offset some of that drain if I don't drive for a few days.
