Usage of Polycrystalline Solar 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 and stable quality, our cells can greatly improve the performance of Solar Modules.

Applications of Polycrystalline Solar Cells

Assemblies of photovoltaic cells are used to make solar modules which generate electrical power from sunlight, as distinguished from a "solar module" or "solar panel". A solar array generates solar power using solar energy.

FAQ

 

We have organized several common questions for our clients,may help you sincerely:

 

  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.

  1.  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.

  1. 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.

  1.  Can you do OEM for us?

Yes, we can.

  1. 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:Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?
We seldom see poly solar cell with the size of 152, because that is not really good to use.
Q:Is solar cell technology very developed and v applied to life a lot?
Yes, solar cells are very commonly used in the commercial military, industrial, areas.
Q:How do people price solar cells? Is it based on a specific way of calculating the cost of solar cells?
The solar cells price is high, because it will take at least 8 years to recover the cost of a the solar cell power supply system.
Q:Can the solar powered cells really work better than the normal cells?
Yes, it does work much better than the normal cells, but the solar powered cells also has its disadvanges.
Q:The difference between a fuel cell and a solar cell
At present fuel cell system fuel - power conversion efficiency of 45% to 60%, while the thermal power and nuclear power efficiency of about 30% to 40%. (2) Hazardous gases SOx, NOx and noise emissions are low CO2 emissions are greatly reduced due to high energy conversion efficiency, no mechanical vibration.
Q:How's the feedback of using 260 watt photovoltaic solar panel? Anybody ever used that?
The conversion efficiency of the 260 watt photovoltaic solar panel is 18 %,which is already much better than the one I used before.
Q:How can I calculate the cost of using solar cells if I put a fully-functional solar system in my house?
Sunrun solar lets you get started for as little as $0 down, but to install it, it will cost you a lot.
Q:What is the solar cell?
The structure of solar cells is diverse. Now, PN-type solar cells composed of P-type semiconductors and N-type semiconductors are used. They are mainly composed of P-type and N-type semiconductors, electrodes, and antireflection films.
Q:Is a solar cell expensive to make?
No, it's not expensive because the most expensive part is the silicon.
Q:What is the current situation and the recent progress space solar cells in China?
The power generated by solar cells is the main and most important energy sources in the out spacer, which makes this technology so vital in our country. You can imagine if we have enough and stable power generation generated by power cells, we will make a huge progess in the research and development in space.
