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:Need help with Solar Panels (FAQ's and opinions)?
You need a plan as to what you are going to with 80 watts of power. 80w at the best, it will usually be less. One problem I have is the limited specs, you don't even know the voltage. And you get a Sharp Module but nothing else is mentioned about it. I wouldn't buy it unless you can get full specs on it and on the Sharp Module. With no specs, it's difficult to get a refund if it is defective. If you are going to store it and use it for an AC appliance, a small one, you will need: a charge controller (to control the charge into the battery) a lead acid battery (to store energy for when the sun is out) an inverter (to convert 2 volts DC into 20 VAC) and all of these cost. .
Q:Solar Panels question?
I would suggest getting more info about solar panels, here's the stuff that could be helpful to you renewableenergyarticles.blogspot....
Q:Are Solar Panels worth it in Southern California?
There are several factors to consider when looking into solar power for your house. If you want to replace your use of utility electricity with solar power for say a 500 - 2000 square foot home then the system will cost you at least $30000 - $50000 to install. You will also have the maintenance issue of your storage batteries, panels, and inverter which will eventually wear out over time. So lets say we have an optimistic price of $30000 for a whole house system (this would be really cheap), dividing this by your yearly consumption would give you the amount of years it would take for the expenditure to pay for itself (not counting maintenance which could be costly). The payoff would be about 25 years, so all things remaining equal, I would say that it is a bad investment. Solar panels as they are manufactured today do not have a very long life span. They will greatly decrease in efficiency after several years and will most likely need to be replaced in 0 years. The panels themselves are the greatest expense. You could problably find better ways to make/save more money by investing $30000 - $50000 somewhere else IMHO. Solar technology is still not at the point where it is profitable in the sense you are thinking about. Unless of course, there are huge tax incentives for you or large rebate programs through your local utility, but you would have to do the math on that as well. If you are thinking small as in a couple panels to supplement your utility electric, the above still applies as well. In fact will it take longer to recoup the cost of a smaller setup. Hope this helps!
Q:kilowatt solar panel help?
You would be amazed how often I have answered this question. The answer is that it depends on your latitude and local weather . Let's see if I can give you enough information so that you can determine the answer for yourself. A kW solar panel is rated at kW when it is exposed to a solar flux of kW/m^2 (called a peak sun hour). There are readily available tables of effective peak sun hours per day by city (see Reference ). Let's use Fairbanks, AK as an example (it is the first line of the table). Fairbanks get an average of 3.99 of peak sun hours per day on average. So your panel would produce 3.99 kW*hr per day on average.
Q:Are photovoltaic cells the same as solar panels?
Solar panels are covered with photovoltaic cells that convert sunlight into electricity. So photovoltaic cells are part of solar panel. renewableenergyarticles.blogspot....

Q:should i get a solar panel?
Solar panel is one of the best sources nowadays to generate electric energy using the sun rays that comes from the sun. But, this set can be so hard to find and it’s very expensive to buy.
Q:How much energy would this solar panel produce?

Q:Anyone here have residential solar panels?
Check out what someone did in Oakley, California - Contra Costa Times 22 June 2007 Going Solar Can Pay Off On The Long Run PGE Electric Power Monthly Bill Before Solar = $,200. Home: 2,900 sq. ft. Installation Cost for 6.7 Kilowatt 36-solar cells $46,000 (minus $7,60 State rebate). New Resources Bank, a “green” bank in San Francisco, lend them a, no-fee, no-points, second mortgage at $200 a month less than their previous monthly payments because of their plan to install solar panels. PGE Current Electricity Monthly Bill After Solar = $7.63 after deductions for any excess power produced by solar cell which PGE.is legally required to buy. PGE has not build any new electric power plants in California for years and their profits do not depend on sales volume, Sen. Feinstein introduced a bill to make this a National Law. Poweful interests are against this, perhaps they are foreign companies that hate Americans? Surely, they are not bona fide, red blooded Americans that love all the people in the U. S. of America, you think?
Q:What is the most powerful solar panel made?
There are various solar farms that run turbine generators that have some rather large arrays. I suspect they'd be in the southwest but i've seen pictures of them covering a few acres. You won't find very large panels because its best to keep the panels small and just have a lot of them. This is because its much easier to have a thousand 0m^3 panels then huge 0000m^3 panel because you achieve best performance when you can align the solar panels to always face the sun. With a huge panel, you would need it to be high off the ground so it can manuver around. Small ones can all be menuvered on a small scale only a few feet off the ground so they can all be pointing towards the sun to gather the most light.
