Solar power’s popularity is rising. In recent years, that’s definitely been true and its popularity and use will only continue to grow in the years to come. More and more people are realizing the value that solar power brings to households and even to businesses.
It’s just hard to beat it, especially with the continued rise in the price of other sources of energy. And you also have to weigh the negative impact that they have on the environment, which solar power doesn’t have.
When we say solar power, the image that immediately comes to mind is the solar panels that are installed on the roofs of homes. Now that’s definitely an accurate if not a little incomplete picture. So most people know what solar panels look like or at least have an idea of how they appear.
But a lot are still in the dark when it comes to the technology that’s behind them. How do they work and how are they able to harness the power of the sun and transfer it to homes?
So how do solar panels work? Please read on this article from Solar Panel Fort Worth and be enlightened by the sun’s potential and power. It can be revealing and serve to show why those who know are attracted to shift to it as their new source of energy and electricity.
After all, sunlight is readily available and its abundance is seemingly inexhaustible. But how does that sunlight become energy that can be used in appliances and other things at homes and businesses?
Start with what is probably the most important component of the solar panel, which happens to be the photovoltaic cell. The photovoltaic cell or cells needs to have as much exposure to the sun as possible so they’re aligned to receive the most sunlight.
As sunlight strikes the surface of the cell, direction and momentum are provided by the electrical field to the light-stimulated electrons. This will lead to a flow of current when the solar cell and electrical load are connected.
Making up each photovoltaic cell are those special materials that are similar to silicon and are known as semiconductors. This special material allows the solar cell to absorb a certain percentage of the solar energy when the sunlight strikes it.
Once the solar energy is inside the semiconductor, it’s able to knock electrons loose and give them the freedom to flow. Electric fields that are also in the photovoltaic cells force electrons to flow in specific directions.
The flow is actually an electric current and they are drawn by metal contacts that are on top and bottom of the cell. This current is used for powering external electrical loads through the use of a power inverter. Any excess power produced can be stored in battery storage systems.
The process above attempts to give an answer to the question – how do solar panels work? It might not provide a truly complete picture nor does it includes all of the details, but it at least gives an idea of what goes on in solar panels.
