What parts should you choose for your photovoltaic installations?

June 8, 2023

The development of solar energy in Europe

The photovoltaic sector covers all activities linked to the production of solar energy using photovoltaic panels. The principle behind these panels, installed on buildings or on the ground, is to convert solar radiation into electricity using photovoltaic cells. This electricity is then connected to the electricity grid.

In December 2022, the European Commission held a conference to launch the new European Solar Photovoltaic Industry Alliance (ESIA), as part of the European Solar Energy Strategy, included in the RePowerEU plan.


Its ambition? To encourage the installation of facilities that will enable 30 GW of annual production capacity to be reached by 2025, by supporting the development of innovation projects and facilitating investment in the construction of a competitive industry in Europe.

In a strategic, fast-growing market, our experts in Germany and France are on hand to advise you on the choice of parts from our catalogue of over 30,000 references.
