A solar panel transforms pre-existing energy emitted by the sun into electricity by absorbing it in. Although some of the terminology used in the production of solar power is a bit complex, it is not overly so.

The process of generating and transmitting solar energy

The solar panels generate an electrical field when sunlight strikes them. It then flows into a conductive wire inside the solar panel. This delivers power to the inverter. It then converts the electricity from direct current (DC) to alternating current (AC). This is what powers your house or any building. Later, the alternating current power routes through electric panels to distribute electricity throughout the structure.

What happens to the surplus energy generated by the solar panel?

Excess solar electricity generated by solar panels is possible. The excess energy passes via the utility meter and into the utility electrical grid.

The chemistry of a solar panel

However, solar panels are made up of several photovoltaic cells. Photovoltaic cells are the components that transform the energy of the sun into useful energy. These cells are made up of a few layers: semi-conducting material set between metal and a few additional components.

Through the addition of phosphorus, the top layer of silicon on these cells acquires a negative charge. The silicon’s bottom layer receives a boron dosage. It generates negative and positive electrical charges because of the metal utilized in these cells.

This electric field pushes the electrons to move in one direction toward the conductive metal plates in the cells.  This flow refers to as an energy current, and its strength affects how much electricity each cell can produce. When the sun shines on the array, electrons from the phosphorus liberate, resulting in the generation of electricity.

Sometimes when you need more power than your solar array generates, you can draw supplementary electricity from the grid via the utility meter.

Solar technology has evolved over the years, resulting in a plethora of new solar innovations. Scientists have developed extremely thin cells capable of producing the same amount of energy as before.  These cells are just 1.3 microns thick and so light.
