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:Why are solar panels so expensive?
The only way I know of is to invest the money in the stock market. Most savings accounts only pay 3% intrest. While stocks float and if you don't know what you are doing you will never make as much money as you could save on your electric bill. Then the fact that you have to pay the electric bill out of the money. In the end you rented electric and can never get your money back. You can always sell the solar electric system and get your money back plus a profit. Not many people live in the same house even 20 years so it will sell. Toss the coin. It is what ever is best for you.
Q:What are the properties of Solar Panels?
American scientists have developed a new coating, which allows the solar cells to cool on its own, without relying on costly cooling and ventilation. Coating increases the output power and prolong the life of solar batteries .
Q:energy and solar panels?
It depends on the size of the solar panels and the intensity of the solar-light. So, there's difference in every place. It's impossible to answer unless there's detail of panel size, panel quantities, average rainfall, average solar days, etc.
Q:With everyone thinking green...how green are solar panels?
All kidding aside, you will possibly desire to do not forget that the White abode is the suited representation of the u . s . to the worldwide. because of fact of this that's equipped so vast and ambitious, and ambitious. image voltaic panels and wind generators will tutor a destructive connotation, form of like antennas on a boarding abode with wires putting down ought to characterize a ghetto to the castles and empires of the worldwide. there is likewise the reason for uninterrupted electricity throughout the time of an attack on the capital, it continues to be a area of the regulations of conflict you recognize. including option potential sources might supply a splash as to how the device works, or no remember if it somewhat is not that way, might come throughout the time of as being hypocritical, or purely for tutor (Like that's not being achieved now...)
Q:Solar Panel and Wind Power?
Insolation, okorder.com okorder.com/... that are 420x420x25 mm so each unit is about .764 m3. If you used these to cover 500 sq ft then you would need (46.45/.764=) 263 of these panels at a cost of ($09.95 x 263=) about $28,953 plus wiring, plus brackets, plus an inverter, plus batteries, plus a battery management system and any labor or your time. Best of luck with it.
Q:Information on making solar panels?
I doubt that you are going to want to learn how to dope your own silicon wafers, add contacts and laminate them into PV panels.  I also doubt that you're going to even want the various chemicals to make e.g. cadmium-based cells anywhere near your house (cadmium is a very toxic metal).  In other words, making your own solar panels is not an at-home project. You can buy solar panels based on cells of several different types.  A link to a Pricewatch-like website for current prices on solar panels is below.  Mounting panels to roofs or pole mounts, running conduit and wires, and installing battery banks and inverters are within the capabilities of skilled laypeople. More data at the links. Edit:  I am reporting all of Agua-Luna's cut-and-paste pieces as spam.  I encourage others to do likewise.
Q:Solarcity free solar panels?

Q:What is maximum system voltage in solar panel?
Hi No i very much doubt it could produce that sort of voltage so get a voltmeter and check it. bright sunshine and dark.
Q:Would you put solar panels on your home? and why?
Why: ) It's a great technology. 2) It has low impact to the environment. Why Not: ) Initial cost is substantial. 2) solar panel technology is greatly improving. I would hold out for a few more years when you can actually use it as a sustainable source and as a replacement source and not so much a suplimentary source.
