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.

8) 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.

 (9) Can you do OEM for us?

Yes, we can.

10Can we visit your factory?

Surely, I will arrange the trip basing on your business schedule.

Q:what is the cost of a solar panel
Photovoltaic solar panels are priced by the watt. Average price today is just under $4.00 per watt. More efficient panels take less space to produce the same amount of electricity. To design a system, you first must decide how much power you are looking to produce. then you look at the various products to find what fits your need. if you have a very compact space, you may pay more for more per watt for really efficient panels, but if you have a good amount of space you can get lower cost panels that take more space and cost less. With a wind turbine complimenting your system you will only need a modest battery storage bank. 5kw system could get you off grid entirely! 5,000 watts x $4.00 = $60,000. 3kw system with net metering mat cost about $2,000. Many homeowners (like me) build their systems piecemeal to keep costs manageable. Good Luck! P.S. - If you build it with the house, the price can be rolled into the mortgage. $60,000 would add +/- $300.00 a month to your payment, but you would have no Electric bill, a savings of $00-200 a month. Once it is paid for, you only have to pay maintenance costs.
Q:Do solar panels float?
With the Oceans rising as fast as they are, I hope so. LOL
Q:Has anyone used portable solar panels for home use?
I think you'd be disappointed. But you might be able to take an RV, park it close to your house in the sunshine, run an extension cord from your house connected to a small fan and run the fan for free. I don't think it's worth the expense of the RV, but that's me. If you have the money, flaunt it baby, flaunt it.

Q:Good Idea To Install A Solar Power Energy On A Restaurant?
To begin with, you need to know how much power you need and then decide from there just how much you can or will have to pay to get that money back. Find a couple companies that do this kind of work to give you some figures to work with
Q:WHAT ARE THE SOLAR PANELS ON POWER POLES?
Here is an article about this. They use the poles (which they already have) and install power panels, the electricity is given into the grid. There are companies in NJ which use google earth to find buildings with large roof tops (imagine all the warehouses !), contact them and lease the rooftops to install solar panels, there a different ways how to finance that (by them, by the company, ....) and they sell the electricity into the grid and receive a certain price for this. Usually the refinancing is 5 - 7 years of the investment, after this is profit for additional 5 - 20 years. Walmart had a project to put solar panels on the super centers ....
Q:Solar Panel Help? Beginners?
Go with the 20W kit. Possibly he can get this going and light up a 5 watt bulb? Does he have an inverter? Sounds like fun! I may look into this later. I did notice that our interstate uses these small ones along the way for something. I have something more interesting; plans for a window solar panel box made out of most scrap items lying around. Just moved so have to unpack and find those plans! Anyway, have fun and hope your dad likes his kit.
Q:Where can I get free solar panels?
If they're just to be used as an example, go around your neighborhood, and find a yard with solar yard lights. Then ask the owner whether you might borrow one or two. If they say no, move on and find another house. I'm pretty sure someone will say yes, after you explain what it's for. They will trust you, because you could have just stolen the lights, but instead asked. Option B is to have your parents take you to Fry's Electronics, and purchase a solar item, like a motion detector light, or even a standalone solar panel. As long as you don't mess up the box, you should be able to return it later for credit. But that's borderline dishonest, because you never intended to keep the merchandise.
