Solar energy, an inexhaustible, clean source of energy, is playing an increasingly important role in the world's energy mix. At the heart of this electrical revolution, photovoltaic solar panels represent a key technology. These devices, capable of converting sunlight directly into electricity, are the fruit of a long series of scientific discoveries and technological innovations. From the first observation of the photovoltaic effect to the current worldwide democratization of solar panels, their story is a fascinating one. It tells the story of how mankind learned to harness the sun's energy - an abundant, renewable resource - to produce clean electricity. This article traces the evolution of solar panels, highlighting the major discoveries that marked their development, the first significant uses, notably in space, and the current challenges facing solar panel producers and users. As our society moves towards more sustainable energy solutions, understanding the history and potential of photovoltaic solar panels is essential.

In a global context of energy crisis, at a time when the electron is becoming the sinews of war, in a world where we can no longer ignore the human impact on the environment, self-consumption of renewable energies is a real vector of transition. The idea of becoming an electricity producer may seem complex, but it's not. The legal, economic and tax frameworks have been in place for several years now, making it easy for any individual or legal entity to set up a self-consumption power plant. We break it all down for you!

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?

The WIND my ROOF contact box is full of requests for information, often very pertinent... and sometimes a little far-fetched. Because there's no such thing as a stupid question, and because behind every query lies an opportunity to learn more about how the wind and our WindBox work, we asked Antoine to deconstruct these atypical requests with kindness...

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?

While all flat-roofed buildings are eligible for a rooftop wind turbine installation, in reality two steps are required to identify the ideal building. The first is to select sites with high production potential according to certain criteria; the second is to check the technical feasibility of the installation. This article summarizes the criteria for selecting a building for installation, and presents one of the methods used.

On June 28, MEPs voted to ban internal combustion engine ^vehicles1 by 2035. Only cars powered by "climate-neutral" fuels will be allowed on the market. This resolution will lead to the electrification of our mobility and could result in the evolution of electricity production, which could then diversify and decentralize. If all cars became electric, what would be the impact on electricity consumption?

A year ago, WIND my ROOF tested the latest version of the WindBox in the wind tunnel at the Centre Scientifique et Technique du Bâtiment (CSTB) in Nantes. The aim was to validate the prototype, with a view to industrialization and first installations in 2022.

WIND my ROOF has called on SEGULA Technologies and its subsidiary SIMRA to industrialize and assemble the first eight WindBox wind-solar modules, due for release in February 2022. The aim is a long-term collaboration with the French engineering giant.
