Can you build your own solar panels?
Pullings and generate electricity welcome to the future. Under the Sun, the Sun is able to produce electricity panels covered with photovoltaic cells, convert sunlight into electricity. This blue plate is a module made of crystalline silicon.
The grooves are the conductors and the silicon crystals glisten edit surface to make a solar panel. Several modules have to be connected together. Then they apply a soldering flux on each module. The soldering wire is heated with an iron.
The modules are placed on a special support. Once the soldering is done, the modules are cleaned by ultrasound in water at 60 degrees centigrade. When dried, the perfectly clean modules are ready to be assembled.
Now they can proceed with soldering the modules by groups. First, a flux is applied which improves the quality of the soldering with great dexterity. They assemble four groups composed of nine modules.
Each in this way, 36 modules are soldered and connected in series modules are assembled end-to-end. They have to be handled with great care using a voltmeter. The voltage of each module is verified at this stage.
It’s, easy to remake a solder connection. If there’s a problem, if the voltage is adequate, they use suction grips to make handling of the nine rows of modules easier and to keep them clean. The modules are placed into position.
Then this metallic strip is inserted, which is a conductor that will link the four groups of nine modules. Solder connections are made to link the modules to the metallic strip. Then they put on this transparent sheet of layered glass.
It serves as a rigid, transparent form which will support the modules superposing of parts forms a laminate which increases the rigidity and solidity of the panel. Finally, a sealing film is applied to protect the module to laminate and stiffen the solar panel.
It’s placed in a heated oven from which air has been vacuumed out. The panel will cook at 80 degrees centigrade for 15 minutes. The oven, hermetically reseals to proceed with the vacuuming out of air, and here’s.
The finished panel. All the components are bonded together. They now proceed with the test. The panel is placed in a solar, simulator, negative and positive. Contacts of the solar panel are connected to a voltmeter you, the panel is inserted into the simulator and a powerful lamp will illuminate it.
The voltmeter is read to make sure that panels supply the electric current required you here now is the assembly of another kind of solar panel called the amorphous silicon type. Its components were made in Europe and Asia.
These here are the positive and negative connecting wires of the solar panel. The panel was placed into a plastic frame and glued in place. Then the frame is screwed tight so that it won’t move. The solar panel made up of crystalline silicon modules.
Is put onto an ABS plastic frame, it’s now finished. Fabricating this panel will have required about one hour of work. Six of them are made here every day. You
