How to make a Solar Cell ?

Learning how to build a solar cell is actually not that hard, however learning how to build one that is powerful enough and one that can sustain itself for a reasonable length of time is another issue. The theory behind solar cells is complex, however it can be simplified and explained as follows.

Photons that occur naturally in the sunlight hit the solar cell panel and are absorbed by the material in the solar panels such as silicon.

How to make your own Solar Cell

The photons knock electrons loose from the atoms in the silicon, which allows them to flow through the material to conductive wires to devices that are connected to the solar cell.

This process generates solar power and produces DC or direct current electricity, which can be stored in batteries or converted to alternating current by an inverter. Some photons will pass straight through the silicon, they can bounce off the silicon surface or the photons can be absorbed by the silicon to produce electricity.

How you start building your own Solar Cell:

Make your own Solar Power Cell and generate Solar Power

There are many proposed plans available on the Internet that will explain how to make your own solar cell. Some will actually suggest that you can build them from scratch, however these are generally very low power and not really useful for more than demonstration purposes.

Readers should consider ordering kits that include the actual solar panels with all of the necessary connections and instructions.

For practical purposes you will need the following items to make your own solar cell system:

  • Solar panels to generate solar power
  • Mounting hardware to support and point your cells towards the sun
  • Connecting cables to a battery
  • Battery
  • An inverter to convert DC current to AC current if you wish to connect AC appliances to your solar cell.
  • A charge regulator to control the charging of the batteries and terminate the charging once the batteries are fully charged

Most people will want to build a solar cell system that they can actually use for some specific purpose such as powering lights in an emergency situation or providing power at some location were there is no traditional power source or adding power to the AC Grid.

Note that all of these subsystems must be rated for the level of power you intend to generate. For example a 3kw system should use components that are rated for 3 kw's.

Further considerations when generating your own power

Other considerations that consumers should take into account are redundancy and wiring. If you plan to use your system for primary purposes, then adding redundant components might be warranted to avoid losing power to your appliances if one component fails.

Wiring can be expensive. A DC system will require additional wiring to all areas that you plan to distribute power to in your home. Connecting your solar cell to your existing internal AC wiring will save wiring and provide power to your homes electrical systems and appliances. If you plan to connect your solar cell system to the AC wiring and hence to the AC grid, consumers will also need a net metering system which contains an approved inverter for connecting to the AC grid and delivers full sine wave low distortion AC power to the grid.
