Power, film are an Iowa based manufacturer of flexible thin film, solar panels that provide custom, solar products for industrial, consumer and military remote power applications. First, let’s say the material must be produced.
The basic role processing where we make the core solar module begins with a roll of plastic. A very thin roll tends to be somewhere around 30 microns thick and maybe a thousand feet long. That roll goes through a sequence of deposition machines to put down first aback metal contact, followed by the semiconductor amorphous silicon, actually six layers of amorphous silicon, which makes the solar cell itself that’s.
The part that absorbs the light and turns it into electricity and then a top conductive layer that is also transparent less to light in, but also is conductive enough to bring the electricity out the front face.
So he has a medal on the back of a transparent conductor in the front that’s, where you get the power out from here. That film is then loaded onto a laser scribing machine. Here the role isn’t wound on a machine that uses laser heads to scribe the material intersections that begin to make up the individual solar cells on the roll from here, the rolls are moved on to the printing stage.
Electrical insulators are printed between the individual solar cells in order to isolate the positive and negative sections, as well as also being run through a silk or print machine. The silver print machine prints, conductive silver ink particles that increase electrical conductivity.
Once it’s been tested, it goes through a process where the copper busbar is put on, which is something we will solder to to get the electrical connection later then, a laminate is put on the front surface in the back surface and that’s, usually a Teflon type product that is highly resistant to chemicals and water.
Moisture will protect the module from the environment. The roll is then routed into a die-cutting machine. This machine aligns the roll and die cuts it into individual modules, which can be used in a variety products: [, Music ].
The die-cut modules are then loaded into a machines that test each module electrically one at a time. The machine places each module onto a lighted, surface and probes check electrical characteristics.
The modules are then sorted into pass and failed in [, Music ] passing modules are then loaded into a large machine called they’ll pick in place here. A robotic arm picks up individual modules, checks them for orientation and then races them onto a fabric surface.
The robot keeps placing modules on a fabric in a pattern that has been determined or the computer [ Music ] once completed a laser cuts. The fabric piece forming the outlines of the foldable solar panels.
Panels are taken from the pick-and-place station and operators, then stream. The modules together on the fabric body, using a flexible multi stranded, wire known as a misfire. The steps here include using a soldering iron to burn away small sections of lamination over the conductive tape.
Multiple connections are made to ensure that solar panels are still operational, even if a wire breaks once that is all done, we will run it through a lamination process through a high heat lamination process which helps bond everything together helps we seal so that the moisture resistance Is improved? The panels are then moved to the sewing cell.
Here, the edges of the panels are sewn. With the edges of the panel sewn, a top fabric wrap is added product labels are stitched on and strips are sewn over. The wire attachment points in the finishing cell, the operator adds a circuit board and connector Rohit & # 39.
S are added to the corners which allows the user to strap down the panel in windy conditions. Completed units are then taken outdoors for a final test prior to packaging. Passing units are then packaged and moves to the shipping department in cases ready to provide a limited solar energy across the globe.
