 WHAT ARE SOLAR PANELS?

Solar energy has been used since ancient times for domestic, agricultural and transportation work. But, it was from the discovery of the photovoltaic effect in 1839 by Edmond Becquerel that subsequently led other researchers such as Charles Fritts in 1893 to build the first solar cell.

The interest in protecting the environment and reducing the effects of global warming, and with it there has been a boom in the massive use of this type of devices, applied even in the home in order to reduce costs and reduce the consumption of conventional electrical energy that has been seen is one of the causes of environmental deterioration.That is why it is necessary to understand how technology works today, as well as the innovation and physical and chemical advancement that each of the properties of this device contains.
