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:Any recommendation for best solar panels?
If you are looking for the best solar panels, you should know that there are a variety of top manufacturers such as SunPower who make these panels. When shopping for solar panels there are a variety of choices you will need to make including what kind of panels you prefer. There are two main types of solar panels, traditional PV panels and thin film panels. GE solar panels are an ideal choice for residential, commercial or even industrial customers who want to harness the power of the sun. Hope the recommendation is good.
Q:How does Solar Panels works and what is the cost of getting a solar panel installed.?

Q:Can cold light make solar panels power
light - heat - dynamic - electric conversion method through the use of solar radiation generated by thermal power, usually by the solar collector will absorb the heat energy into the refrigerant, and then drive the turbine power generation. The latter process is the light-heat transfer process; the latter process is the heat-to-conversion process, which is the same as the conventional thermal power generation.
Q:How many Solar Panels for my Pool?
I don't think heating a 70,000 gallon pool with solar panels is practical. My husband has designed and built our solar hot water system. It works quite well. We live in Arizona. There's no way we could heat that much water using sun energy. You have to heat the water and compete with the outside air.
Q:how much money do solar panels cost?
Consider installing building energy measurement first, which cost less than $200. Work out what is using the energy and if there are more efficient options. Consider co-generation which uses gas for an energy input and electricity generation and heat as an output. Use the Solar Energy Calculator to work out how much solar panel area is needed to generate the remaining power needed in you are of the world.
Q:what is the cost of getting km sq of solar panels?
Solar panels are being improved on a continuing basis. Price is coming down and performance is going up. Still, they are expensive. A panel roughly /2 X /2 meter runs about $00. It generates 0 watts of power. To make a panel km square would take 4000 of these at a cost of $400,000. They would generate 40,000 watts or 40 kw or 0.04 Mw.
Q:Are solar panels a viable option in IL?
You can do solar anywhere and yes, they're a viable option in IL - as they are where I live - in Maine! We get snow and also lots of low light days in the winter. It's not as easy as say -having solar in New Mexico (self-identified as the solar capitol!) but - you can still generate a nice amount of electricity with your solar panels on a nice day in IL - and they're fine in the snow.
Q:How are solar panels developed and distributed in America?
The first link below is one of the best sites for recent news about solar panels. You should be able to find stories about solar panels under development today. A little bit of the history: Solar panels have been around for about 50 years now. They were first used to power spacecraft. Solar power for domestic use started to develop rapidly in the 970's during the first oil crisis, but as energy prices fell in the 980's solar development slowed. Most of the large solar panel makers were purchased by large oil companies who seemed not to be too interested in solar. In the late 990's as concerns about both Peak Oil and Global Warming grew there was renewed interest in solar power and a number of new companies were started to develop new kinds of solar panels. Many of these new companies have grown larger than the older solar companies still owned by big oil companies. Over the last 7 years or so growth in the solar market has been explosive with a compound growth rate of almost 40% per year. In 2005 the solar industry for the first time started to consume more silicon than all other electronic industries combined resulting in a world wide silicon shortage that is still with use. New silicon refineries are coming on line and the shortage is expected to diminish by 2008 or 2009. Check out the two links below. They will help you a lot.
Q:Does infrared radition occur in solar panels?
Solar panels do heat up. But that's because the radiant energy from the Sun that lies within the infrared (IR) band of energy causes the material in the panels to heat up. And that's the same for any body that has the Sun shine on it. Your face, for example, will heat up while you get a nice tan on the beach. That's due to the heat producing IR radiant energy. Now if those solar panels are supposed to heat buildings etc., that heat produced in the panels when the IR strikes them will be transferred, usually by some fluid, to floors of the rooms to be heated. And as the amount of heat generated by the Sun is proportional to the area of the solar panels, bigger areas of panel will generate more heat than smaller areas. Photoelectric solar panels are another kind. Here the interest is in the visible band of radiant energy from the Sun. Heat, from IR, is still there, but it is not the product sought by PE solar panels. The visible light photons knock off loosely bound electrons from the photoelectric material (typically silicon based) and those electrons are siphoned off as current. That's where the electrical power comes from for buildings using PE solar panels to provide their own electricity.
Q:Are solar panels a good idea in Seattle Wa?
If you have southern exposure . Go for it.
