An affordable solar panel system will be beneficial as it will cut down the cost of expensive electric bills. Each year the costs of solar cells decrease and are available at cheaper rates.
Steps to build your own solar panels.
1.Buy the cells – There are various types of solar cells to purchase but the best option will be polycrystalline cells as these cells are cost-efficient. Buy according to your need relating to how much wattage you want to produce.
You must buy extra cells. Please make sure to handle these cells carefully as they are fragile.
These cells are easily available online, you can also buy these cells from your local hardware store.
2. Take the exact measurement of the board and cut it- You are required to have a thin board that is made of a non-conductive material to join the cells to. Now put down or lay the cells in arrangement depending on your usage.Then, take the measurement of the board’s dimensions and cut a board to that particular size.
Make sure you leave extra inch at both ends of board without fail, as this space will be beneficial and will be used for the wires that will tie or attach the rows together.
3.You must now take the measurement and cut your tabbing wire- When you see your polycrystalline cells, you will notice that huge number of minute lines are going in one certain direction(this is referred to as the long distance) and then you will notice two larger lines that are going in different direction(this is referred to as the short distance). You are required to connect or attach the tabbing wire to run down two larger or bigger lines and then you need to connect to the backside of the next cell in the arrangement. Next, you need to take measurement of the length of bigger line, double the length of larger line, and the you need to cut two pieces for each single cell.
4.Now you need to use the flux pen on each of three squares of every single line (this is generally two or three lines) on the back of cell.
5.Now the next step is to heat the first half of tabbing wire of strips to bond or relate it to the cell.
6. This is the most essential part of this entire set up process
Connecting the cells
Stick the cells with the help of glue at back-centre of the cells and press them in correct place on the board. Note that the tabbing wire should run appropriately in straight line through every single row. Leave an extra inch at both ends of the board without fail.
Now, Solder the cells together – You must now apply flux to the length of two thick lines (these are also called contact lines)on every single cell, then you must take free sections of tabbing wire and then solder them to total length of pads.
The tabbing wire that is connected to back side of one cell must connect to the front of next cell in each case.
Then connect each row appropriately to the wires in first , second and each row.
This is how you can build solar panels. Be careful while performing electricity tasks and it is recommended that you take help of a professional electrician.
