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 made from silicon and not magnesium?
Silicon is a very good conducter. Probably the best for electricity.
Q:what is the cost of a solar panel
Solar panels will come down in price each year from now on.. so any price now would not help you much. I just bought a panel for $00... What you have to compare is the type, output, size, durability, warranty, and other features.. The prices vary a lot, depending on these variables. Another option you may want to consider is just buying green power from a provider. Texas and New York now allow this... Other states will deregulate soon I hope. To learn more about the details, along with specific instructions and the ability to comment and discuss or ask questions; go to
Q:Solar panels don't work when it's too hot/sunny?
A good sunny day is best but allthough high temperatures will effect the output from the panel it will not be as affected as much as a cloudy day would.
Q:Hi trying to learn more about Solar panels!?
solar panels collect the suns energy and turns that into electricity that is then stored in batteries. attached to the batteries is another device that takes the power from the batteries and turns it into power you can use in your house. it is a very expensive power alternative.
Q:Where can I get damaged solar panels?
When you pass a sign- look at the back of it for a name. Often the company that rented them out will have their name on the back. Call them.
Q:Can a solar panel work with an inverter?
There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.
Q:Is there a personal use solar panel?
Yeah they have them to charge phones but to use a microwave you would have to use one to charge a 2 volt battery with them from there an inverter . You could probably get a system like that for around $50 or so off OKorder . Don't get me wrong solar panels do cost allot but for what you want it for just to run a microwave isn't going to cost you all that much . Just go to OKorder and look for solar phone charger and get an idea of what you want . Thumb up for Sam above me . People just think everything is expensive because they put no effort in there shopping .
Q:Solar-Cell-panel help please?
I hope this will help you choose your charge controller / battery charger more effectively. Good luck!
Q:Shouldn't 0bama increase our tax benefits for solar panels so we can buy more Chinese products?
China is also the world leader in using solar panels. Most solar panels in the US are not from China. There are several companies here in the US that make solar panels, and many states do increase the tax rebate for buying local products. Most flat plate water heating panels installed in the USA are made in the USA. Wouldn't it be nice to get people to buy more sustainable energy products and increase manufacturing jobs in the US, while actually improving the air quality and reducing our dependence on foreign oil? Oh, and perhaps we could get the money by cutting the amount of taxpayer funds subsidizing the oil and coal industries?
Q:what does a single solar panel weigh?
