A large thin plate consisting of number of solar cells connected to each other is called as solar panel. This thin film is made up of crystalline silicon. The silicon is a good conductor of heat but it does not have the ability to absorb the sun’s light. Hence some impurities are added to it for the flow of electrons. To build your own solar panel kit would be cheaper rather than getting installed it from contractor.
How to build your own solar panel kits
1. Introduction to basic solar energy
Now to build your own solar panel kits one must know the basic knowledge of solar energy. One should know how the solar energy is converted into electricity. Also one should study each components which are required to build own solar panel kit.
2. Build own solar panel
This section includes the wiring of solar panel. The solar cells are connected in series. 36 solar cells comprise of 36 watt energy. Bus wiring connection is used to connect all solar cells to each other. All the strings get connected to each other and at the end a large string is obtained.
3. Drilling the holes for the component
Now the pegboard is drilled where the solar cells are attached to the frame. Then the two connections are made to obtain; one is positive and the other is negative.
4. Gluing Solar cells
The solar cells which were attached to each other through a string are now glued to the ply board to get fixed on it. The solar cells are glued using silicon. Now the wires are soldered to each other. After this check the voltage or current rather than waiting for the solar cells to get connected.
5. Soldering bus wires
After hooking all the 3 strings of solar cells up in series, the panel was ready to get its 22 gauge wires of red and black which is now ready for soldering. On the ends of the leads from the gauge wires, connect some connectors to make the process of soldering much easier rather than difficult for the bus wiring solder.
6. Electric side
Now it is the time for the electrical side of the solar system. generally, a charge controller, deep cycle battery, and an inverter is required. To connect those together is very simple. First hook up the solar panel wirings to the solar side of the charge controller, and then from the battery connection side that of the charge controller, I hooked that up to the deep cycle battery. From the battery now hooked that to the inverter and now it is ready to work.
7. Pressurizing each side
In order to secure the solar panels, pressurizing each side is necessary. The Plexiglas is carefully drilled on the solar panel in order to avoid crack. This Plexiglas provides more pressure on the solar panels.
8. Junction box
Now the junction box is connected at the back of the panel. This junction box consists of blocking diodes which help to prevent the back flow of the current.
Now it is ready to be installed on the top of the roof.
