About us

As a result of the merging of the companies ELECSOL and ATESOL, founded in 1979 and specialised in the distribution of photovoltaic material, APLICACIONES TÉCNICAS DE LA ENERGÍA, S.L. (ATERSA) was born in 1983.

From its start, Atersa developed, manufactured and commercialised all the components necessary for the configuration of a solar photovoltaic system through its own production lines in Valencia and commercial offices in Madrid and Valencia.

Among the first products developed by the company was the installation and commission of several photovoltaic systems to supply electrical energy to navigation lighthouses, telecommunication relays, rural electrification, water pumps and public lighting, among many other applications.

At its Almussafes plant (Valencia), which is over 20,000 m2, and at its different location, Atersa has a production capacity of up to 344 MW. Atersa is currently a subsidiary of Elecnor. It provides highly specialised engineering and supplies the best comprehensive solutions for solar systems in national and international products, offering a technology that uses renewable, clean energy that the sun provides us with every day.
