Manufacturing

Our production of solar cells has for many years Conducted by Swemodule AB. Swedish companies thathave Their registered office in Glava, Värmland. The Factory That produces our solar cells was one of the world's most automated factories for the production of solar panels. It has automated soldering of bothering ribbon and connection. With this automation will be very even quality solar panels and the committed few mistakes, the quality is consistent, all the solar panels are virtually completely identical donor. Because of a nerläggning of Swemodule we have each had to find a new partner who can laminate and ramsätta our solar modules. So with the help of formsStaff of Swemodule we clean now a production line in northern Italy to laminate and frame The choice of material in our solar panel today is the same as before with a few small improvements and we have not saved money by Reducing material quality to price war in Those lower ranks, but we have the concept of Retained That we "know" works. Of course, the products run in weather chamber to be able to be surethat the solar cell providesprofessional energy in the 50 years we have That guarantee. We have learned through the years That the Nordic Climate husband's great Demands on the solar cells When the buzzer May have 30+ degrees and in winter have 30- degrees and hurricane. We are in the north widerange ofPut our solar module, of course this is a bit more Tedious Because of the distance to the production, but with staff who are willing to be long periods in Italy while using freight trains, it has worked better than expected. However, is the major part of the job is still in Sweden as the material for frames, solder, all orders and purchases as well as the development and construction Which is of course the Most Important Part of this work. Swemodule started production of solar panels in 2003, Which means That They solar cells, today we deliver have confessed color for over 13 years, we also have solar panels installed From The BeginningUntil today, there are few Producers who can show the real installation thathave been around for so long.climate and our solar cells are unlike many Competitors Built to tooth with this. Of course, we have our new factory the same materials as before. (Why go from a concept That Works?)

How is the production of a solar panel to?

I will try to explain the process of module production as well as I can. 1. It begins with of course the purchase of materials, this party Is that you do not believe One of the key elements in a production of solar cells, I would think it overpriced ice The most job behind the right to find materials that fit together and Manage They incredibly high Demands we place on it. Entrusted everything to a solar panel Capable of an incredibly Difficult environment with UV light, salt, rain, heat and cold, and this also in the Achieve 50 years. Few products have this Requirement in itself. 2. It begins with picking robot Adds front glass face down. 3rd The same robot then camp N Cloth EVA.Ethyl Vinyl Acetate. (The materials lateralis That glue the laminate) and now ships this disk to the next step in the process. 4. While paragraph 3 takes place as work next produktionslinamed picking silicon wafers on a treadmill, Which sets out the ribbon (silver copper strips That Electrically connects the silicon cell) for soldering in the silicon cell, this process is probably the most Difficult in Production , Which requires incredible pressison on soldering and posision of ribbon. Ribbon-legged Also at this point to avoid stretching the silicon wafers. This line together When The solder 10 series-connected cells, In Theseis it 2 ribbon through all the cells. It also checked all the silicon wafers visually optical computer, so there are no faults or cracks in the silicon, we want to note add soldering job on any broken silicon. There is a translation of a visual and electrical inspection of solder to make surethat the solder is OK and That everything looks good. 5. Now have we got was one of the Six silicon lines to be included in a solar cell. So now pick a ROBBOT These Soldered 10 silicon wafers, They Add to the prepared plate Previously picked up. This does one do with 6 rows for a total of 60 pieces of cells in a solar cell. 6th Now this panel on the soldering of These.Soldering now so you get 3 pieces loops with 20 cells in each loop. Here you use thicker copper tape to the tooth with higher current. This soldering operated by two robots. 7. Now, the first manual control where you visually check the soldering and measure as distance between cells and frame edge is within godkännda values, this willalso box of the solar panel first marking by sträckkod were entered into the laminate for full control of what it's for Solar Which cell panel and the data it has. After this are shallower and the EVA Also a white cloth thatwill serve as the solar panel jaw (Backsheet). EighthNow After the complete plate with glass, silicon, ribbon, EVA, and back into a vacuum / heat press. It added That disc between two blankets, heated , then up to about 155 degrees while the vacuum sucks out all the air in the laminate 9. There must not be any air pockets in the finished laminate as it will destroy the solar panel rather quickly. Now we have a laminate That is completely homogeneous and without air pockets to be Furthermore out into production after cooling. 10. We will now trim the laminate edges so it keeps the correct measurement of the scope later, this is done with the robot, Which cuts the panel against a knife. 11th Now it's time to glue and solder the connection box.This is done with lödrobbot and optical control, computer control to make it properly. Glue is a translation applied by the robot in the assembly of the connection box. 12. Now, the frame must be fitted. A robot plastics tape around the laminate So THAT It will be good press fit in the frame. 13. Currently a press table with frame profiles and corner. Then take a robot laminate and plastic ring it at the press table to table, then be able to squeeze there the framework of the laminate. Now is the frame in the right place but are not marked in the corner even to hold together. 14thA robot is now the solar panel to a press That characterizes every corner to bring sustainable and homogeneous frame, When this is done, put the solar panel in the UV light boxWhich will radiate solar panel with a light That correspond to 1000W / m2 solar irradiation, This is a process to ENSURE That the solar panel is working and the measurement of what the solar panel performance. Based on this data, it is classed solar panel in the right power class and the power label is created. It is a translation of a megging to ENSURE That no ground fault will exist in the future. Meggningen performed with about 10000V to ENSURE the isolation of the product. 15. Now the finished solar panel is controlled manually, this check it for errors, brands, and hundreds of other references to finally be able to get an approved solar panel.In this test rate Also solar panel and this will Decide Whether It has a visual appearance That is approved. 16thNow pick the robot solar panel and take it to place it on a pallet. This pack robot keeps track of all classifications and position the solar panel on the right pallet in relation to the classification, the ice 1:10 speech class solutions in the form of various Power Stages etc. It also lays out the corner brackets to the solar panel must be correct on the podium When you have the full pallet (40st panels) so running it to inplastningsrobot and then run it on the warehouse properly pallplatts to wait for transportation to customers.

Solar Panel, a single product?

Solar panels are Relatively quite simple product with few parts, none of These parts move up or create any mechanical wear. Yes it is and it is what makes solar panels to a product that you do not have to Maintain, and is then a simple product to own. But the downside To that is simple turns out to have problems if the product or any part of the product is not up to scratch, so it can not be repaired. You can not replace the back-to something better or a bad ice cream against a good , but you have connected to the product you Bought, and has since received a product that does not agree or meet the requirements of the environment it is in so you can not do anything at.Difference If you have a car factory has bad brakes or bad wheel bearing or a poor Sterio so you can always replace These party with slightly better, but with a solar panel has only one chance to influence the durability and it's for purchases. Entrusted to it is a simple product, there are the production many pitfalls you can fall into such product will not be what you thought, unfortunately, turns out wrong Usually after a year and only chance to get a product that measure is to be taken into purchase. The choice of material is one of the key elements in a solar panel, it does not matter how well you put up solar panel if the material is not up to scratch. And of course it is so That a poorly Soldered orlaminated product will not work either, Regardless of what you have chosen for the material. So to be sure of the quality of the product Should ENSURE thatthere is a good story for manufacturers and there are references That Extend back in time and a break-party certification, and material handling. Yes, how do you do this to be surethat you Invested Money That You'll get it back? Yes, it 's about feeling safe with the company it is and the larger investment might ask , Should Contact the manufacturer and check So THAT the Information Gained is consistent with the manufacturer's Recommendations, Check That All the certificates and CE and EN-labelsreally exist and are true, talk to others who have done business with the company you are talking to, ENSURE thatthere are effective system thathavegone gone A few years (at least 8 years old) on the neck With These products and the same material. We are not accustomed themeselves to check products in this way, but so far are solar panels so young in Sweden That no company has made real tests and inspections on the Companies That are doing this. We are used to read a test in a test newspaper or magazine When We buy a car or a computer but unfortunately we are not therewith solar panels yet. So a good purchase requires a lot of buyer if it will be good. The sellers of the brunch is lubricated with many allies so it is veryhard to be sure what is Truth or scam.
