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 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:how are solar panels practical?
Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy.
Q:what is the volts of 75watts solar panel?
Many of the panels used on homes are designed to produce 2 volts DC. 0 of them wired in a series would produce 20 volts DC. An inverter is used to change the DC voltage to AC. The other aspect of electricity is amperage. With electrical units wired in series the voltage is added. When they are wired in parallel the amperage is added. The Volts x Amps produced will give you the wattage. A wise homeowner will examine their electric bills or the equipment used to determine their demand. They will consult tables that let them know how much sunlight their area receives each year as this will alter the rated performance of the panels. Then they will try and determine how much of the demand they want to fill. 80% may be economical. Then they also want to determine what they will do with excess electricity that may be produced during the summer months of intense sun and how they will supply the shortfall of low sun winter months. From all this they will determine the number of solar panels they need to purchase.
Q:2v vs 24v solar panel?
The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.
Q:questions about solar panels for residential use?
Almost sure that you will discover everything related solar power at www.okorder.com.
Q:Is heat a factor in how much energy is gained when using solar panels?
Nope. Sunlight is.
Q:How does solar panels work?
Solar panels are built with light-sensitive panels. These panels soak up the energy from the sun's light. This energy is changed to electric power. This power is stored in batteries to use whenever / wherever it is needed.
Q:How do solar panels and their battery backup systems work?
First, you didn't say the voltage. Second, 30 W/hour per day. Third, battery backup capacity in Ah = Ampere hour. For 2 Volt DC here's the calculations : 30 w/hour means = 0.83 or rounded Ampere hour. You know peak time 5-7 hour (let say 6 hour)charging time (collect the sun energy). Ampere hour per day (24 hour), with 20 Ah Battery backup is OK. And the Solar Panel is 3 Ampere charging capacity minimal = 3 Amp x 6 hour = 8 Amp hour.
Q:What direction do solar panels usually point?
South in the northern hemisphere. - this gives you sunlight on the panel a major portion of the day without the need for a mechanism to follow the sun or change direction from E to S to W as the day progresses
Q:Im a bit confused about what a solar panel is?
A two KW system would be made up of a number of solar panels. Panels used in residential and commercial systems usually run in the range 50 watts to about 200 watts. There is a HUGE amount of information available on the internet about solar panels and all the components of solar electric systems. All you have to do is search on the internet under solar panel. It's very safe and easy. So just do it.
