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:Solar Panel experts...please help.?
Unfortunately, I can't give you a lot of specifics on what you should use. However, I can tell you that the very best system for you simply might not be available to you, in which case it really doesn't matter how good it is. Your best bet would be to talk to a supplier in your area and see what is available, THEN start looking at the differences between those. Unfortunately, solar panels aren't quite to the point of being a common-place product...yet. Another thing to consider would be how old your roof is. You might want to look into the possibility of building-integrated materials if you are in need of a new roof. Talking with somebody who sells the panels in your area will help you understand a lot more than just doing raw research. Get their take on it, then fact check and research what they tell you so you know you're not getting ripped off.
Q:What is the difference between monocrystalline & polycrystalline solar panels?
The polycrystalline solar panel has a longer life-span and has a higher efficiency. What this means is that from the energy that 'hits' the solar panel, more is caught and used to convert into electrical energy. A polycrystalline solar panel will have an efficiency of about 4%. The monocrystalline solar panel has a similar efficiency but the cells are prone to sunlight, so the efficiency drops over the years.
Q:how to charge phone with solar panel?
see u have to make ur own ckt for this ur solar panel generate DC if u want to charge ur phine then its convenient way to harge with ur charger for this do this search for net to convert DC-AC convertor since ur charger work on AC so when ur solar panel generate DC it convert into AC that will charge ur phone in ckt u need this thing filter and amp ie the DC voltage come from solar panel 2 DC to AC convertor 3 AMP for AC 4 filter for AC and u are done....... fine ckt from google.....
Q:how instal solar panel?
There are MANY garden lights with built in batteries and solar panels that you just need to stick in the ground. There are also self contained units that are wall mountable. THAT way there is no need to run wiring, use battery stacks, etc. and will also probably be less expensive overall.
Q:It's all about Solar Panels?
here's lot of articles about the questions you just asked about solar panels, enjoy renewableenergyarticles.blogspot....
Q:Has anyone gotten their solar panel rebates in Florida?
Do not count on getting the rebate soon or if at all. You should get on the list and wait until the funds are released. Good luck. Summary: Note: There is currently a waiting list for rebates from the Solar Energy Incentives Program. This program has received $5 million in federal funding from the American Recovery and Reinvestment Act of 2009 (ARRA). This funding will be used to award rebates to some of the systems that are on the waiting list. The state has applied for an additional $9.4 million in federal funding for this rebate program. Systems applying for the rebate at the present time will be placed on the waiting list. If additional federal funded is received, the approved applications will be awarded rebates based on the order in which they were received. FY 2009-200 is the last year of the solar rebate program and the last year the program could be funded under current authorizing statute. Florida's Solar Energy System Incentives Program was established in June 2006 (SB 888) to provide financial incentives for the purchase and installation of solar energy systems from July , 2006, through June 20, 200. A total of $2.5 million was available for FY 2006-2007; $3.5 million was available for FY 2007-2008, and $5 million is available for FY 2008-09.
Q:how to make your own solar panels ?
If okorder.com/ . Beware of anyone who makes claims you can save tons of money by making your own panels. Those are scams. It's possible to save money with solar, but not with homemade panels.
Q:can a light bulb power a solar panel?
Yes light-bulbs work, sort of, but you have to illuminate every cell. The output is regulated by the cell with the weakest illumination. Additionally the sun is very strong, 000W of light or more per square meter. A light-bulb is weaker, so less output. A 00W bulb may have only 5W of light, and it doesn't cover the panel, so you can expect something like % of the sun's output. The spectrum of a light-bulb is actually more appropriate for a silicon solar panel, as the silicon panel responds best to red colours.
Q:How much energy would this solar panel produce?
Build okorder.com/
Q:Solar panels for home info?
Of the practical technologies, crystalline silicon is still king. There have been improvements in manufacturing efficiency and price, but the fundamental technology is unchanged. For the past couple decades, there have been startups claiming that they will have a breakthrough available in 2 years, but so far, nothing has beat crystalline silicon for general applications. The appeal of thin-film was its cost, at the penalty of efficiency, but when the prices of crystalline plummeted, the cost argument went away. That wasn't the only problem Solyndra had, but it contributed to the company's demise. Organic solar cells show promise, and might ultimately be very cheap to manufacture, as they don't involve the high-temperature processing that semiconductors do. The main problem today is that they're not stable at the temperature of a hot roof. But then again, a few years ago, organic LEDs were the same way, and now they're commonplace in big TV's. Only time will tell. From a homeowner's standpoint, the install is routine, but still best done by professionals. It's like putting a new roof on a house, or wiring in central air conditioning. For most, it's better to call a pro.
