Are solar panels the future?
Solar panels, also known as photovoltaic panels, are made up of several cells of photoelectric cells made of silicon, which allows the transformation of the sun’s energy into electrical energy thanks to the photovoltaic effect. This process is considered a sustainable means of energy, i.e. it does not affect the environment.
Solar panels have an average life span of 25 to 30 years, provided that preventive maintenance is carried out effectively. The materials used to make solar cells are silicon crystals. At present there are many installers of solar panels in Madrid that use this type of material of high durability.
Renewable energies are the future of humanity. It is expected that, within the next 20 years, renewable energy sources will generate 50% of the world’s electricity. This will ensure the progressive elimination of the carbon footprint and thus improve people’s quality of life.

The first solar cells were created in the 1950s, after Albert Einstein described the photovoltaic effect in the 1920s (he won the Nobel Prize for physics in 1921 for this theory). Its main use was in the space field, until around 1970 its use on earth began to be popularized as an alternative to the usual electric current.
The future of solar panels
Solar panels have now been used in various ways, mainly as one of the many substitutes for methods of obtaining non-renewable energy. At present, it is possible to install panels for private domestic use, since the cost of manufacturing has decreased over the years due to the simplification of the way solar panels are constructed.
Solar farms
Solar farms are large tracts of land on which multiple solar panels have been placed to generate electricity. In these places, solar energy is used in a better way and they can provide electricity even to industries, due to the amount of electricity that can be obtained through them.
Currently, some of these farms have a significant technological advance in the form of solar panels that follow the movement of the sun. Just like sunflowers, these plates are programmed to adjust their inclination with reference to the location of our star in the celestial vault.

Transparent solar panels
In 2020, scientists at Michigan State University synthesized a solar concentrator that harnesses infrared light and ultra-violet radiation to transform it into energy that will be converted into electricity. This type of solar panels are intended for use in buildings and urban environments. This would minimize the use of non-renewable energies and easily reduce the carbon footprint.
Although they are still prototypes, they could eventually replace traditional silicon panels. These new transparent solar panels are made from a material called perovskite, which is a type of crystal that is much easier to handle and much cheaper than silicon.
Autonomous cars with solar panels
A prototype car has recently been launched that has the particularity of being electric and powered mainly by solar panels installed on the roof of the vehicle. Although currently the figures are astronomical to acquire one, that is where all the advances in electric cars are heading.

Solar panels are the future that will save the planet from pollution and prevent the collapse of the economy.
