Solar Polycrystalline Series Panels

Introduction of Solar Polycrystalline Series Panels

CNBM Solar photovoltaic (PV) Panel is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array. Monocrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon. Hence most c-Si panels have uncovered gaps at the four corners of the cells.

 

 

Standard Test Conditions of Solar Polycrystalline Series Panels

The opto-electrical specifications shown below are stabilized values being measured at Standard Test Conditions, Irradiance: 1000W/m2, Spectrum: AM1.5 at 25°C, The info below is subject to manufacturing tolerances. Where appropriate minutes of measurement are available and are used for the dimensioning of the installation.

 

Polycrystalline Silicon Solar Cells156mm Advantage:

 

•  High efficiency and stable performance in photovoltaic conversion.
•  Advanced diffusion technique ensuring the homogeneity of energy conversion efficiency of the cell.
•  Advanced PECVD film forming, providing a dark blue silicon nitride anti-reflection film of homogenous color and attractive appearance.
•  High quality metal paste for back surface and electrode, ensuring good conductivity, high pulling strength and ease of soldering.
•  High precision patterning using screen printing, ensuring accurate busbar location for ease with automatic soldering a laser cutting.

FAQ

 

We have organized several common questions for our clientsmay 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.

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

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.

Normally we put the panels in carton and then in pallets.

4.       Can you do OEM for us?

Yes, we can. It will depend on the quantity.

Q:Solar Panel costs and sizes?
Take a look at the website from Retscreen International. This is a site sponsored by the Canadian government and they have everything that you will ever need to know about renewable energy. Download the free software and then feed in the position of your school (GPS Coordinates) and some data about energy useage. It will then link to the NASA websites to tell you the weather and work out what size of solar panel you need, what direction it should point and what angle it needs to be mounted on. I've used it for the UK, Afghanistan, Iraq, Jordan and other countries - It's brilliant - and its free. It also links to manufacturers websites and so gives you costings. Use this and you are guaranteed to be top of the class
Q:What does solar panel power?
I doubt it'd supply your heat. Anything involving electric heating uses tons of energy. Also, keep in mind that you don't just need a panel but also a DC to AC converter.
Q:A Question about Solar panels?
You have to know the amperage to figure out the watts. Volts x Amps= watts
Q:How do you make solar panels?
it takes a ton of them to power a home most only put out 45 watts, [cheaper ones] solar is not cheap its more expensive than electricity
Q:do solar panels work in aeroplanes?
As long as the solar panel has access to light it will operate. If you can keep it in the sunlight it will work a lot better than off the internal lights on the plane. Depending on the plane/lighting/your position, there might not be enough ambient light available for the solar panels to run your laptop.
Q:Solar panel for your home?
The first thing to understand is that there is nothing complex about a solar panel. It is nothing more than a collection of solar or PV cells on a board that is fitted to the most appropriate part of your home, generally on the roof. There are guides out there that teach you how to build a solar panel and a windmill for just $50, and it’s very easy to make. Best of all, you can save 70% or more on your energy bill, adding up to thousands of dollars each year in savings. I reviewed both free guides and paid guides and have come up with our top to Build your own solar panels.
Q:How do you store energy using a solar panel?
probably a deep discharge lead calcium batteries, with a switching regulator cycloconverter or cycloinverter output to match the current and voltage requirements of the operated device.
Q:What capacitor should i use to store energy from a solar panel?
Solar Capacitor
Q:Can I install solar panel straight to battery on my truck?
Solar Panel Battery Maintainer
Q:How many LED's can power a solar panel?
Your question has a lot of science involved that I don't understand perhaps the link posted in my source for this answer could help you out? It a site containing only info on LED Lights. Good Luck
