How does a photovoltaic panel work ?

At the forefront of the energy revolution, solar panels are really taking off! How a photovoltaic panel works is very simple to understand, and understand it you must if you want to invest in this type of installation to generate some or all of your electricity from solar energy. One of the advantages is that solar power is unlimited and free, and considered sustainable. With a solar roof from Terreal, you can provide your home with a conscience-free and environmentally friendly system.

Here's how a photovoltaic panel works: the protons emitted by the sun hit the photovoltaic cells contained in the panel. A voltage is created between the two layers of the cell, the electric current. You can sell this current back to the grid or use it for consumption inside the building that has the panels. Do not underestimate this energy source; it can supply up to 40% of your overall consumption! Saving money by preserving the planet is the principle of the solar panel.

How a photovoltaic cell works

A photovoltaic cell is an electronic component that produces electricity when exposed to sunlight. These little squares, gathered together, form the module of a solar panel. On average, there are between 60 and 72 per panel.

Photovoltaic cells work based on the semiconductor properties of the materials used. The cells that make up the panel are what convert the solar energy into electricity.

The particle of light, called a photon, loses its energy when it lands on the photovoltaic cells. This signal generates free electrons that move back and forth, creating a current similar to that of a battery. These are connected to inverters that convert the direct current into alternating current, to feed it into the grid or consume it on site.

For optimal efficiency, but also for the photovoltaic cells to work properly, it is advisable to have a roof sloping to 30° and to be south-facing. It is also better if there are no shade sources, like trees, which will obscure the panels.

The solar panel, an ecological and virtuous principle

The principle behind the solar panel is to enhance the energy produced by the sun by converting it into electricity.

Photovoltaic panels work in such a way that it is possible to generate economical, non-polluting, readily available energy. This type of energy should be favoured, habitat permitting, because it is environmentally friendly and addresses more global ecological issues, real concerns of our time.

Everything you need to know about RE2020 regulations

The RE2020 regulations came into force at the beginning of 2022. They have been put in place to gradually replace RT2012 by setting more ambitious targets for reducing greenhouse gas emissions from new public and residential buildings, during their construction as well as their use. The RE2020 regulations also take adapting the building to climatic conditions into account.

Solar panels in the north of France – a profitable investment

Let's put a stop to any misconceptions here and now – installing a solar panel in the north of France is profitable! Whether you live in Lille, Paris, Nantes or Strasbourg, there is a whole host of advantages to investing in solar energy. Solar panels work on levels of brightness rather than heat from the sun. Because of this, they offer a high yield even on the roofs of houses and buildings located in the north of France.
