Product Description:

Solar cell module production process

Line called packaging line components, packaging is the production of solar cells a key step in the packaging process without a good, multi-well battery is also not a good component of production boards. Battery package not only the battery life is guaranteed, but also to enhance the combat strength of the battery. Product quality and high service life is to win can be the key to customer satisfaction, so the quality of components of the package board is very important.  

 

Process is as follows:  

1, the battery test

2, positive Welding - Inspection –

3, on the back of cascading - Inspection –

4, laying (glass cleaning, material cutting, glass pre-processing, laying) –

5, laminating –

6, to flash ( to the side, cleaning) –

7, fitted border (glue, loading angle keys, punching, install box, scrub I glue) –

8, the welding junction box –

9, high-pressure test –

10, component testing -- -

11 appearance inspection, packaging and storage;

Q:how would you build a solar panel?
i'd go to the solar panel store and buy one. It would be /0 the cost of trying to build one in my HOME shop.
Q:Why are solar panels grid-like?
Solar cells are semiconductor devices like computer chips. Current manufacturing methods create small squares of semiconductors. Companies are researching ways to make thin film solar cells that can be painted on or manufactured in large, possibly flexible sheets, but so far the technology to do that is still more expensive than making little squares and then assembling them into big panels. That may change in the near future, but I can't be sure.
Q:Solar panels with snow?
Solar panels to almost 90 degrees. Clean off snow and spray with MINERAL SPIRITS. I just figgered this out during a snow storm today here at 8000 feet in So. Colorado during a wet and sticky snow. Panels are clean. Sealants used on panels are impervious to MS. Jesus loves us all.
Q:what is the best solar panels to use on my new house(tube or flat)?
I assume you're talking about heating water. Based on what I've seen, the spiral tubes seem to heat the water to a higher temperature than the flat panels, probably because the water has to follow a longer path and has more time to heat. This type of panel will heat the water to a high enough temperature for almost any household application, but you need to be careful about how you set it up. I once saw a pool that had been equipped with that type of heating system, and it produced enough heat to melt one of the PVC pipes. It was a vertical pipe next to the filter, and it had fallen over onto the ground, pinching off the flow of water. This was in Arizona, so it may not get that hot in your area.
Q:solar panel help needed ?
One square meter of solar panels can produce up to 50 watts of maintenance-free power for up to thirty years. The most common solar panels are for 2 V applications. For sq meter: I = P/V = 50/2 = 2.5 A A single solar cell always produces a voltage of approximately 0.5 volts, regardless of its size. For higher voltages, you have to connect individual cells in series to add their voltages. The larger the solar cell, the greater the current will be. You can also connect cells in parallel to increase current. Hope this helps!
Q:can i join multiple solar panels?
That depends on the product of solar panels you buy. I was recently talking to an installing company that sells solar panels that have the DC to AC built into each panel. That way you could simply string them together and add as much as you want as you can afford it. It really isn't much more expensive than any other method of install.
Q:Why are solar panels so expensive?
It's all in the production process that uses materials and processes that are not yet cheap because of the little infrastructure in this field. You can make cheaper solar panels, but it restricts their efficiency, so you get less energy. The reason individuals haven't been catching on to it is because it is not yet entirely cost effective. For a normal 3-person home to be powered completely by solar, depending on many conditions, especially where you live, the payback period is something over 50 years. I live in Boston and for my house to be powered by solar I wouldn't see it making money for over 75 years! What people have to realize is that the point of solar is not to completely power your house cheaply, but to lessen the strain on the electrical grid, and if enough people do this the cost will certainly come down. That and the technology of solar panels has been developing unbelievably fast with all of the green energy buzz going around, so you should see the cost dropping in the next few years as new discoveries are made.
Q:How to make 2V 4.5A solar panel from solar cells?
The simplest way to use these panels is simply to connect the panel to your battery, with a diode in series to prevent the battery from discharging through the panel (no sunlight condition). Just connect the battery for the required charge time then disconnect it. Full sun is required, no shadows on the solar panel! ---------- .
Q:How to select solar panel for this application?
Be aware that you cannot discharge the full capacity of a lead-acid battery without destroying the battery. With a normal battery of this type, you would only want to discharge about 20%, so you would need a 70 AH battery bank. For the 3-day requirement, 500 AH. This is still within reason. If you didn't have the 3-day requirement, you might consider going with NiMH batteries. Back to the 500 AH bank, you would usually charge at at least 5% C, or 25 amps. At the 5 volts that you need for charging, this is 375 watts. Possibly you could go as low as 200 watts.
Q:cheapest solar panels sold on line?
Solar panels installed are roughly $0/watt in commercial quantities. Bare panels? Do a google search and see what you can find. But for the record, there are panels and there are panels. Stuff from China put together in a shed somewhere will not perform in the same way as some of the new thin-film amorphous panels coming out of the US and Europe. So, in many ways you get exactly what you pay for.
