How to build solar panel

A solar panel is a booming business. With this sustainable form of energy, electricity may be created which does not hurt the environment and minimizes carbon footprint. It also assists in minimizing power expenses.

One clear benefit of creating your own solar panel is that they are significantly less costly and you may personalize the solar panel according to your power demands. Following are the steps required to create a solar panel at home.

Step-1: Creating a frame to support the solar cells

The first step is to design a frame for your solar panel.

This structure will protect the inside components of a solar system from temperature and mechanical pressures. Solar cells are exceedingly fragile and need to be protected with the assistance of a frame. The frame also features mounting attachment points.

The frame should not have sharp edges and it should be electrically and mechanically conductive and earthed throughout. It may be fashioned from wood, glass, plywood, or plastic.

Step-2: Purchase solar cells

Solar cells are made up of a semiconductor substance i.e. silicon. These cells capture solar energy from the sun and convert it into direct current (DC) which is then transformed into AC using an inverter. This AC current is utilized to power our dwellings.

The quantities of cells you buy depend on the amount of electricity you are seeking to create with your solar panel. Following are some of the aspects that should be kept in mind when acquiring solar cells.

  • Solar cells are quite fragile so be sure you get spares.
  • Each cell shouldn’t cost more than $1-2 per watt.
  • Solar cells come in varied sizes with typical solar cells around 6 inches broad. It generates 1.75 watts each. If you desire additional electricity, you can get larger solar cells.
  • Monocrystalline solar cells are somewhat costly. The optimum cost-to-efficiency choice is polycrystalline solar cells.

Step-3: Testing the solar cells

Testing solar cells is a crucial operation since one damaged solar cell may impair the performance of the complete solar panel. The solar cell should be checked for both voltage and current.

Step-4: Preparing the solar panel’s front and rear side

After testing the solar cells, the next step is to create the front and backside of the panel. The front side of the panel will be composed of a transparent sheet of acrylic and rear with white acrylic sheet. The solar cells will be inserted in between these two sheets. Acrylic sheets are popular since this material is waterproof, corrosion-resistant, and robust.

Step-5: Assembling the solar cells

In this stage, design the physical layouts of solar cells on the frame and start connecting the solar cells to each other. Solar cells must be linked in series to acquire maximum voltage value.

Step-6: Test the strings of the solar cells

After connecting the solar cells together, check the strings to make sure that they are operating correctly and giving correct Volts and Amps. Place the strings of solar cells in the sunshine and use the multimeter to evaluate the voltage and current value coming from each solar cell of each string.

Step-7: Connecting strings of the solar panel together

After anchoring the strings of solar cells with backing, the following step is joining the strings together. For this reason, the bus wire (a thick wire) is employed. Use the soldering iron, flux, and solder to link the threads together.

And finally, install the junction box at the back of the solar panel.

Final Thoughts

The solar system works for around 25-30 years so it is crucial that you consider the upfront cost and relative benefits. If you buy the material and install the panel yourself, it will cost you less but the quality will be compromised.
