Solar energy, an inexhaustible and clean source, is becoming an increasingly important part of our global energy mix. At the heart of this electric revolution, photovoltaic solar panels represent a key technology. These devices, capable of directly converting sunlight into electricity, are the result of a long series of scientific discoveries and technological innovations. From the first observation of the photovoltaic effect to the current democratization of solar panels around the world, their history is fascinating. It tells the story of how humanity has learned to harness energy from the sun, an abundant and renewable resource, to produce clean electricity. This article traces the evolution of solar panels, highlighting the major discoveries that have marked their development, the first significant uses, particularly in the space sector, and the current challenges faced by solar panel producers and users. As our society moves towards more sustainable energy solutions, understanding the history and potential of solar PV panels is essential.

Renewable energies may complement each other, but they are rarely seen together, due to lack of available space or hybrid technology. What's the best choice between wind and solar power?

By the end of 2022, 21 of France's 56 nuclear reactors were shut down. In 2021, almost 70% of electricity will be generated by this energy source. Against a backdrop of both energy crisis and transition, the diversification of production methods via renewable energies needs to be developed. Over the course of history, many machines have been built using wind power. Some were used to grind grain, while others were used to generate electricity. Today's wind turbines are the fruit of multiple evolutions. What inventions have influenced their development?
