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;

FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A: All products offered by OKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What is a solar PV module?

A: A solar PV module consists of many solar cells that are connected together (typically in series) and packaged in a frame (typically made of aluminum).

Q3: What are the advantages and disadvantages of monocrystalline solar PV modules?

A: Monocrystalline solar PV modules are the most efficient type of solar PV modules, with the exception of CdTe thin film solar PV modules. As a result, monocrystalline solar PV modules are more expensive when compared to almost all other types of solar PV modules.

Q4: What is the typical service life of a solar PV module?

A: The typical life of a PV module is 25 years. However, superior quality PV modules boast service lives up to 35-40 years (electrical generating capacity is often reduced, however by that point).

Q:how much do commercial solar panels cost?
HOW MANY PANELS FIT IN THE ACRE FIELD? acre = 43560ft² First of all you can not fill the whole acre field with solar panels. There must be space between them so you can walk amongst them and so they don't shade each other. So let's say you can maximally cover 50% of the area. 43560ft²/2= 2780ft² a medium efficient, medium priced polycrystalline solar panel of 200w covers 6ft². So how many can we fit in your field: 2780ft²/6ft²= 36pcs of 200W solar panels can fit on the field 36pcs*200w= 272200W =272kW of total power harvesting capacity per full sunny hour. HOW MUCH WILL THE PANELS COST? Since you will build such a large solar farm you will want to get the cheapest panels possible. the price per watt on solar panels today is as low as $,5. that will mount up to: 272200W in total *$,5 cost per watt = $408300 for all the solar panels HOW MUCH WILL THE EVERYTHING COST? The whole shebang will be much more expensive since you are going to need inverters, wiring, fuse boxes, handy men to install it all and so on. A 5kW total solar system costs about $0000 if bought from a solar company. that would mean $0 000 * 272200W/5000W= $544 400 for the whole shebang But I strongly believe since you are buying such large quantities you will be able to get better deals then the rest of us mortals. And then you will have a power plant making you free electricity for the next 25- 40 years to come. And you don't necessarily need to set it up in a particularly sunny place for it to be cost effective. Just look at this gorgeous solar Farm from France
Q:Solar panels........................?
solar panel is a good product which can use clean energy and convert it into electricity for people use. and will decrease the pollution to the environment.
Q:Solar Panels and a Car Headlight?
It should illuminate two auto headlights on a sunny day, if it really generates 50 watts at 2 V. On a cloudy day, I don't know. It depends on how cloudy it is.
Q:Wanting to add solar panels to my home?
Unless there has been some major breakthrough in solar panel efficiency - Forget it. I had looked at some utility interactive systems where the electricity generated by the solar panels went through a special inverter and into the electrical system of the house, any power you didn't use went backwards through the meter and into the grid. I figured that even if it was sunny every day, it would take about 20 years to break even on the system. That is, if I had invested $5,000 in a small system, to save $5,000 off the electric bill would take 20 years. If I had $5,000 to invest, this wouldnt be the place! It would take much more than 20 years of electrical savings to match even a modest investment. Then, don't forget what happens if 0 years from now the inverter or some of the panels fail and need replaced. Invest in fluorescent lights, maybe even LEDs. You will see a much quicker return on investment. Install more insulation, put in a heat-pump system. I appreciate you desire to save some energy, solar just isn't going to be worth doing, at least not yet.
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:What is the anatomy of a solar panel?
You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
Q:Solar Panel - Battery Charger 2V?
If you want to run something from a solar panel, you should remember that the power from the panel is only available when there is reasonable sunshine on the panel. Usually the solar panels are used with solar regulators in order to charge batteries. These batteries are used as energy storage for when the sun is not shining. Now, this does not mean that you cannot drive instruments directly from the solar panel and regulator. To do this, you will need a panel that has sufficient power to drive your instrument. An example is the solar powered garden or fountain pumps. I have driven 2V computer fans directly from the small solar panels - useful for cooling of things such as pool pump housings. The solar regulator is used to convert the solar panel output to a 3.5V output in order to charge lead acid batteries. I have used MPPT regulators (maximum power point tracking) which is more efficient than the standard solar regulator. If you don't use these regulators you may find the solar panel producing up to 7-9V in good sunshine which is not good for your instruments that are expecting 2-3V. Hence the answer to your question is that you will need to have a battery being charged to get useful power from the solar panels via a solar regulator.
Q:I need help finding Solar panels for a boat.?
Rate ,power , voltage and effencicney are four important iterms to choose one battery.

Q:What are the main components of a solar panel?
The basic components in home solar heating systems include: Collectors to take the heat from the sun and pass it to a fluid The heat transfer fluid which takes the heat from the collector for use or storage Heat exchangers to transfer the heat from the fluid to a home’s domestic water. Pumps to move the fluid through the collector and/or the exchanger, and sometimes to move the domestic water through the other side of the exchanger. Controllers to run the pumps when there is collector heat available.
