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:Solar Panels in the 200 Toyota Prius?
Solar Roof Prius
Q:Why are solar panels still so expensive?
We all would love to have solar panels, I wish I could afford them for my house! The fact of the matter is that the amount of energy used to make solar panels doesn't really make it beneficial. They would have to have a better way of manufacturing them, a way that uses less energy. Basically they don't make up for the energy lost in their production .Despite our efforts there is no fuel like fossil fuel.
Q:Can you get energy at night from solar panels?

Q:LED Lantern Charged via 6 volt solar panel?
If it has a 6 volt battery- is it marked 2 volts on an external plug? If so, there is a resistor inside to drop the potential the battery sees. The battery itself could be slipped out and recharged easily from your 6 volt panel. Just determine how much current (in Amps or Milliamps) the panel produces nominally and divide that into 4 and add one fourth of that length of time to make up for system losses. This will tell you how many hours it should charge assuming your starting voltage of the battery is above .5 volts. and the panel is at 3 volts potential or higher. So if your panel puts out amp at 0AM, you would charge for 5 hours. 4 divided by is 4 and one fourth of that is so 4 plus is 5. It is a little more involved than that, but as a rule of thumb. Also do not discharge tha lantern to the point of no light output. LEDs are efficient, but their current will add up. If it is suggest to be able to use the lantern for up to 8 hours on a charge, stick to that value. Lead acid batteries have best longevity when discharged only to 80 percent capacity. Once battery is charged- disconnect from charging source.
Q:It's all about Solar Panels?
here's lot of articles about the questions you just asked about solar panels, enjoy renewableenergyarticles.blogspot....
Q:How energy-productive are solar panels, compared to natural gas?
Solar panels are not nearly as energy productive as natural gas. Case in point how many natural gas fired calculators do you have on your desk? or how many solar fired fireplaces do you know of? Solar panels are a great complement to natural gas/fossil fuel burning sources of fuel though. The more energy you consume from renewable sources of energy (i.e solar, wind, etc) the less you are consuming from non-renewable sources such as natural gas. Solar panel's rate of producing electricity depends on many different variables. Are the panels in direct sunlight? (with no trees or shrubs blocking the panels) There are panels out there made by Kyocera for example that are 85 watts, 65 watts, 50 watts. You should talk with a Professional about this. Look into Sun Electronics as I know that their website has a solar calculator and other helpful tools for interested parties. Good Luck
Q:Can one benefit from solar panels?
Excuse me,Brack but you are totally wrong. Solar panels are not used only for demonstration or experiments.Some of the top corporations around the world use solar panels to great effect.On edit. A short search turned up many stories about practical use of solar panels all over the world.Perhaps you need to brush up on what's going on out there in the real world.
Q:I am doing a Solar Panel DIY?
Sounds like fun. A -watt panel doesn't need a charge controller, though. In fact, it may take more than watt to power the charge controller. With a low-wattage panel, you can just connect the panel directly to the battery. A 7 amp-hour gel cell (the kind used in burglar alarms) would be good for this purpose. The panel is too small to charge a car battery. The gel cell should power that inverter, but only for a few minutes. If you want to be more impressive, look for a low power, 2-volt device. An iPod plus a 2-volt car adapter would be an example.
Q:questions about solar panels for residential use?
If you're in a sunny area, and the cost of electricity is high, solar panels can be worth it. But it's not a big moneymaker, it's something that pays back over long timeframes. We live in northern California, and our system is about break even, but that's because our electricity usage was low to begin with. If you want to see our system, look at the web page in my profile. Are panels worth it in your area? The only way to know for sure is to find a local installer in your phone book, and then ask for local references. If you can't find a local installer, that's a clue, and if they can't give you any references that are nearby, that's another clue. The panels don't actually store energy, the energy is sold back to the power company when what you produce is more than you consume, driving the meter backwards. Again, this is not a big moneymaker, and in fact, it may be impossible to make a profit, depending on your local laws.
Q:Do solar panels make electricity from light intensity or watts?
Light is power in the form of electromagnetic radiation from the sun. We receive about 000 watts per square meter on a sunny day. The solar panels do convert that sunlight into electrical power at a little less than 25% efficiency. Light intensity and power per square meter (W/m^2) are closely related. The more intensity, the more watts per square meter. So the answer is : Yes, from light intensity which directly proportional to watts per square meter
