Solar Module Introduction

Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells. These early solar modules were first used in space in 1958.

Electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. The cells must be connected electrically to one another and to the rest of the system. Externally, popular terrestrial usage photovoltaic modules use MC3 (older) or MC4 connectors to facilitate easy weatherproof connections to the rest of the system.

FAQ:

1What price for each watt?

It depends on the quantity, delivery date and payment terms.

2What is your size for each module? Can you tell me the Parameter of your module?

We have different series of panels in different output, both c-Si and a-Si. Please take the specification sheet for your reference.

3Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Actually we are only manufacturer of solar panels, but we could try to source them for you in China if you need. We could provide you an optimal system design to instruct you how to install.

4Do you have the CE, TUV, UL Certification?

We’ve already passed all the tests, and any certificate is available.

5Have you ever sold your products to companies in my country?

Of course, we have customers in all general PV markets, but I think we should expand our market share along with the market growth.

6When did your company set up?  You are a new company, how can I believe your quality?

We entered into Solar PV industry in 2005, now we have several plants in manufacturing of a-Si and c-Si panels, and our capacity is 220MW per year. Till now we have already passed all the tests by authorized laboratories, e.g. TUV, VDE, UL.

7Can you help us install the module if we cooperate with you?

We haven’t entered into installation sector, but we have the plan in near future.

Q:where to find used solar panels?
IF used panels are available, they are probably worn out and NOT putting out the power they were designed for. (They DO wear out!) I do NOT know of any place they are sold.
Q:How will i construct solar panel?
The first step to planning your system is to evaluate rebate options and obtain permits. Deciding the size of your system is the next step. With a grid-tied system, size is less critical, because the grid supplies power when your PV system falls short. Systems as small as a couple hundred watts are practical, but you can also install panels that will produce enough electricity for all your needs.
Q:electronics help solar panel?
[] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.
Q:What can you tell me about rebate incentives for residential solar panels in New York state?
Go to your state's department of revenue and enter the solar panel thing in the site search box and follow the thread to exactly what is in place in the here and now. Things seem to change on a daily basis any more.
Q:will a 5v 52watt solar panel charge four 2c dv 55ah batteries?
I don't think so, but if it did, it would take a very long time. You need enough wattage or amps to push the power in the battery and 3w may not be enough. You would be better off with a small 2v battery, maybe the type they use for emergency lights. I would use a sealed battery for this type of setup because car batteries are designed for heavy charging with alternators from 60 amps and up.
Q:How much do solar energy panels cost?
Buying solar panels can be very expensive, especially for installation. If your average daily usage is 6.6 kilowatt per hour, then you would need a 2 kilowatt system that could generate ten kilowatts per hour in a day. This system could cost between $0,000 to $20,000. Of course, the higher wattage, the higher the cost. There are some alternatives to spending thousands of dollars on solar panels. ) Buy several solar panel kits and link them together yourself. 2) Combine solar with wind power to decrease the number of panels you will need. 3) Build your own solar panels for around $200 each. If you are handy with some basic soldering, then you can make your own solar panels.
Q:Solar panel setup?

I also have lots of info in my blog to help fuel peoples imaginations to many possibilities that can be found only in the minds eye. Along with lots of environmental info, amazing environmental pictures and videos (These videos show the beauty of this world and what life can be like if people take the time to appreciate life’s true beauty). Let us all strive for a greener/brighter future by helping to create a solid foundation for future generations to build upon, so we can hand them a beautiful world, filled with never ending awe and wonders!! Where peoples differences and uniqueness are accepted, where we all live as one, helping one another so that we can all play our own mysteriously beautiful melodies in the never ending, awe inspiring, song of life :-) I truly have faith in humanity and believe that someday our lives and the world in which we live will truly be transformed for the better.
Q:where to face solar panels?
On a sunny day about noon, hold up a stick move it until there is no shadow...that is the perfect direction to point the panel...but yes...south is the simple answer
Q:im trying to power up a cell phone and laptop with a solar panel.?
They are powered from internal batteries, so what you really want to do is to charge the batteries. Take them one at a time, as they have different power and voltage requirements. Don't try to do them both together, unless you use an inverter. To directly charge a battery from a solar panel, you need to find out the voltage and current requirements for the charge operation. Then find a solar panel with a voltage somewhat higher. the current can be lower, it will just take longer for the charge. You will have to monitor manually the state of charge of the battery(s) to avoid overcharging and damage. Another alternative is to get a solar panel that will supply 2 volts and use that to operate an inverter that will output 20 VAC with AC sockets on it. then you can plug in the battery chargers that you have, and they will handle the batteries correctly. Or you can buy solar panels with built in circuitry to handle the charge control. .
Q:How many wind turbines and solar panels does the world need to replace coal, oil and nuclear power?
There is an abundance of free energy available on this planet. Wave, wind, solar, (underground), and many many others that I can't remember right now. If some of the multi-trillions currently being spent being spent by the US government on defence (and the rest of the planet defending ourselves FROM the US) were re-directed towards exploiting sustainable, long-term energy supplies, then much work would be generated and the cost of energy would drop significantly - in the long run. So, why are we not utilizing these sources of energy? Unbelievably short-sighted right-wing political ideology, that's why! One thing almost never reported about nuclear power, is that there isn't much nuclear power fuel available on this planet. I think I can quite honestly state that when the time comes when we are forced to move from non-renewable to renewable energy production, it will probably be far too late with far too much damage done and the environment will collapse and become incapable of supporting oxygen breathing life-forms. I concluded many years ago that capitalism will probably end all life on this planet one day. Capitalism IS right-wing politics! Do you now see where the problem is coming from?
