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:How to prevent shorting out solar panel?
Just cover the panel and cut the wire the voltage will be so low it would be like shorting out a battery
Q:Cost of Solar Panels for basement?
As Tex said, you have no idea whats involved. Start by looking into some sites that explain how they work and whats involved before asking how much on a small room. And how do you add a basement but not a main floor? and where is the basement roof?
Q:How much maintenance do solar panels require?
Solar Panel Maintenance
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:What happens if I put a 00v, .5A solar panel on a 2V, 450cca Gel deep cycle battery?
The solar panel is capable of /2 Amp output. If you hook it to a 2V battery directly and the battery is discharged it will want more than /2 Amp and pull the voltage down until the battery is charged to a certain level. Eventually the battery will try to charge up to 00V which will definitely damage the battery. If you use a regulator circuit running off the solar panel that outputs 2V then you will have a constant voltage circuit which will still be limited to /2A or whatever the regulator is capable of outputting. Of course you can't just go out and connect 00V to any voltage regulator it has to be capable of running from 00V and dropping the voltage to 2V like the original charger that comes with the battery. The same explanation applies to a 72V battery. You have to limit the output voltage to 72V or risk overcharging the battery.
Q:Where can I get free solar panels?
If they're just to be used as an example, go around your neighborhood, and find a yard with solar yard lights. Then ask the owner whether you might borrow one or two. If they say no, move on and find another house. I'm pretty sure someone will say yes, after you explain what it's for. They will trust you, because you could have just stolen the lights, but instead asked. Option B is to have your parents take you to Fry's Electronics, and purchase a solar item, like a motion detector light, or even a standalone solar panel. As long as you don't mess up the box, you should be able to return it later for credit. But that's borderline dishonest, because you never intended to keep the merchandise.
Q:How to amplify current from a solar panel?
If you want to power both USB ports at the same times, It might not be possibble. Your solar panel only supplies 2.24 Watts (20V * 0.2A) of power and you need to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses from your regulator(s), you will be WAY over your power budget. You will need more of a solar panel or less of a load.
Q:Can I install solar panel straight to battery on my truck?
If you were going to do that it would have to be the right size solar panel and you would need a solar battery charger so it doesn't fry your car battery
Q:can you hand make a solar panel?
