Solar Module Introduction

Solar Module is the core part of solar PV power systems, also is the highest value part of it. The function of Solar Module is to convert the sun's radiation to electrical energy, or transfer it to battery and store in it, or to drive the load running.
The Product has been widely used in space and ground, it mainly used for power generation systems, charging systems, road lighting and traffic signs areas. It could offer
a wide range of power and voltage, and with high conversion efficiency, and long service life.

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:how to build a solar panel?
Can you show us how to build a solar panel ?
Q:How much candle lights is required to operate a 205 watt solar panel?
That's hard to tell. A solar panel produces somewhere between 7 and 0W per square foot under sunlight exposure. You should calculate the light intensity of sunlight, and then calculate the light intensity of a candle (You'll have to look that up in some physics book or the internet) and then just multiply the number of candles until you match the intensity of sunlight. Realistically, you would need so many candles that you wouldn't be able to fit them in front of the solar panels, assuming you don't end up with a huge fireball.
Q:Solar Panel Current=Battery Current+Load Current?
complex task. browse in google and yahoo. that could help!
Q:solar panels in space?
Guide okorder.com/
Q:why aren't solar panels for your house more affordable?
Best okorder.com/... Of course sometimes you can get very cheap solar panels if you are in the right place at the right time... A friend of mine got the solar array from one of the road service companies... it had some minor defect so they were replacing it and throwing away the defective one... it still put out a good bit of power and it was free for him... but that is all luck.
Q:5kw Solar Panel Roof Kit?
Note that aiming is important - the sun is going to be perpendicular to the panels for only a few hours a year unless they are on an adjustable mount, so picking the time you most want power should be a factor in the angle they are mounted at - you can't keep the highest level of sun for summer into the winter time when the sun is much lower in the sky for a shorter time.
Q:how much does solar panels cost for you home?
Although its costs have been going down a little, solar power is still pretty expensive. To power a home you are looking at at between $8000 to $20,000 dollars (it will eventually pay for itself). There are systems that tie into the existing local power supply so that you have the city's power for back up (note: most power companies will buy electricty from you if you make more than you use). Then, of course, there are stand alone systems that operate without anyother power source (these are best for use in a place where electric lines aren't available or practical).
Q:Need help with Solar Panels (FAQ's and opinions)?
This is a photovoltaic panel...it produces electricity from incident solar radiation. Solar thermal panels produce heat, and they are usually assists for hot water heating systems. Solar thermal panels have piping in them instead of semiconductor cells like photovoltaics do.
Q:Are solar panels worth it?
Is an SUV worth it? I have passed many of them off in the ditch while my 2wd truck keeps going on icy roads. Unless you own a company and need the SUV it will never pay for itself. Is a huge house worth it? I can live in a 8X6 foot house perfectly well. Unless you rent rooms out in the large house it will never pay for itself. Solar panels are statements to others like a house or vehicle, except they will actually pay for themselves over many years. Don't expect to get rich off them, but look at it as doing your part to cut down on pollution, become more self sufficient or whatever. The exception is if you build a house far from the grid. A friend was quoted $40,000 per mile to install grid tied power to her house out in the woods. Solar panels paid for themselves the first year there.
Q:Solar Panels!!???!!!?
Solar Panels are collections of solar cells. These panels basically collect the incoming sun's electromagnetic radiation and convert it into electrical energy. A solar cell is any device that directly converts the energy in light into electrical energy through the process of photovoltaics. The development of solar cell technology begins with the 839 research of French physicist Antoine-César Becquerel. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develop when light fell upon the electrode.
