How do solar panels work

Many times we’ve talked about solar panels , but for some time we have been receiving feedback that made us a simple but interesting question: how solar panels work ?. In Erenovable we now explain its operation, in addition to the rise in some cities living as ourselves in our day to day can take advantage of them.

Before you begin to see how the solar panels, that surely have no doubt seen on the roofs of many buildings in your city, we have to speak a little solar energy work.

As you know, solar energy is that which emanates from the core of the sun. It occurs due to a nuclear reaction and melting due to intense gravity conditions to which this subject. The sun is composed mainly of hydrogen and under specific conditions fuses into helium. This process releases enormous amounts of energy, springing from the heart of stars and travel through space for billions of years.

The land which is closer to the sun gets its power and does in many ways , so that the atmosphere and filtered magnetosphere much of the harmful sunlight, but let through the lengths corresponding to the visible light and infrared, so that’s what we get is it’s light and heat. An energy that has become one of the driving functions for life as we know it, as it promotes the most varied effects on the planet’s surface: among others, winds, cloud formation and rain and climate change around the globe.

The man wanted to find and build the most diverse ways to harness this energy and convert them to support life on earth and that is why right now is being heavily optimized technology to extract this energy from the sun and convert it into energy for human use such as electricity and hot water.

Electricity from solar energy:
Speaking of solar power as a renewable energy, we must also mention the fact of having transducers for converting various forms of natural energy into usable energy by man.

To transform the sun’s energy into energy that we can apply to our daily lives, necesitamos one photodetector, and is an electronic device that transforms light energy into electrical energy through the use of a process called the photoelectric effect.

The process is that the light that comes in the form of photons, hits mainly built on a silicon surface (solar panels) and emits emits electrons that-be capturados- produce an electric current.

Currently he is experimenting with solar cells double-sided with the help of reflectantes- surfaces can double the efficiency expanding exposed to sunlight surface.

These cells are what are known as photovoltaic panels and employ complex and precise technology so advanced.

Yes, so far very few companies in the world have the capacity and technical resources needed to produce power.

How do solar panels work?

The operation of the solar panels are based on the photovoltaic effect, which occurs when, on semiconductor materials suitably treated, incident solar radiation to produce electricity as of Previously I mentioned.

At the time when it is exposed to solar radiation, the different content in the light energy transmitted electrons in the semiconductor material which then can break the potential barrier of the pn junction, and thus leave the semiconductor through an external circuit.

These photovoltaic cells are combined in many different ways to achieve both the desired voltage and power.
Not surprisingly, we understand the smallest solar cell module PN junction semiconductor material and capable also of producing electricity.

We must not forget at this point is called the photovoltaic panel on the set of cells that have adequate support and coatings that protect you from weather.

In a future article we will explain in detail the different types of solar panels in the world.
