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 panel, dc light help?
You can't really judge the watts for solar lighting the same way you could for dc lighting. This is because of several factors The lights that you showed ARE NOT high quality lights and furthermore; they are not a well-known brand. Also, I would be suspicious of any store that offers lights for less than half of what other stores do. They are dumping the merchandise, which means it could have been sitting around for a while. MAXSA Innovations makes good solar lamps, so does Solar Goes Green. As the other responder wrote, you are better off using dedicated solar spot lights or floodlights than trying to integrate a solar panel into regular solar lights. A 00 Watt solar panel is pretty strong, and you also would need a battery. Unless you know how to rig up the system with appropriate controllers to make sure too much energy doesn't get into the rechargeable battery (lithium ion or NiMH), you take a risk on having the whole system fry out.
Q:Blocking diode for solar panel?
At least a 2 amp diode. rated above the 2 volts that are commonly found on the market. A blocking diode must be able to stop a higher current and voltage than the panel maximum. A diode will work on any voltage and current lower than it rating.
Q:A Question about Solar panels?
I am sure someone can tall you.
Q:How to make electricity from the sun without using solar panels?
you could use a water container with the sun focased on it and make it so that the water that gets heated goes out of a tube near the middle and the tube would lead to a turbine that generates electricity when water is forced through the tube( like an IV machine pump they use in hospitols only reversed so that it generates power instead of using power) then lead the tube back to the very top to release the water. PS basic principle behind idea is that water moves when heated and slows when cooled HARNESS THAT ENERGY
Q:DIY home solar panels?
Not worth it unless you can get a fat subsidy. But Congress is working on a bill to provide a significant subsidy, and Oregon may have one as well. A solar plant costs about $0 per watt of installed capacity, and can produce a maximum of two kWh per watt per year -- which is worth about two bits. Without a subsidy, you are better off leaving your money in a savings account.
Q:question about GE solar panels?
Retail, between $5 to $6 /watt.
Q:Could you have a solar panel in space?
There are thousands of satellites in space with solar panels, but none of them are designed as power stations. Transmitting power using radio frequencies would be profoundly inefficient. A string of satellites orbiting the Earth would be incredibly expensive. Even if solar power were to reach economic viability, we would put them on the ground where we could use them. Given the amount of advanced renewable sources of energy already being developed there is absolutely no reason to launch a power plant into space. Wow - watched the youtube video... that is possible the worst invention ever and I hope it never catches on. The last thing we need are retards who are too lazy to plug in their phones wasting electricity on highly inefficient wireless transfer when many parts of the world are facing energy shortages. Regular chargers are already bad enough because they constantly drain electricity even when not in use. I am definitely not an environmental saint but this thing is just stupid.
Q:Connecting solar panel help?
never hook up solar panels in series, you reduce the total power produced, and may hurt them, only voltage out, never voltage in. Don't forget to vote for best answer!
Q:solar panels in space?
there are hundreds of satellites in area with image voltaic panels, yet none of them are designed as ability stations. Transmitting ability employing radio frequencies may be profoundly inefficient. A string of satellites orbiting the Earth may be quite costly. despite if image voltaic ability have been to realize financial viability, we would positioned them on the floor the place shall we use them. Given the quantity of stepped forward renewable components of ability already being developed there is quite no reason to launch a ability plant into area. Wow - watched the youtube video... it quite is conceivable the worst invention ever and that i'm hoping it by no capacity catches on. the final situation we prefer are retards who're too lazy to plug of their telephones dropping electrical energy on rather inefficient on the spot circulate while many aspects of the international are dealing with ability shortages. universal chargers are already undesirable adequate simply by fact they consistently drain electrical energy even while not in use. i'm surely not an environmental saint yet this situation is in basic terms stupid.
Q:how many solar panels will i need?
you silly ! with Solar there is always room for error . you have to build it in to your numbers . solar is full of errors . So you should plan on producing at 3 times what you expect you will need . then you have enough .
