Founded in August 1982 by its current CEO, initially as a mere commercial company, RESUL soon became an industrial company, fully or partially participating in the share capital of national factories and interacting in the definition of ranges and strategies of some of its supplier factories.

Between 1994 and 1998, RESUL also set up its commercial subsidiaries abroad, namely in Cape Verde, Angola and Mozambique.

In December 2003, RESUL obtained its ISO 9001 certification, which is constantly renewed every subsequent year.

In 2018, the company created a specific Department in the area of ​​renewable energies, where projects of photovoltaic solar plants for self-consumption are designed and developed, followed, after being awarded, their installation and delivery to customers in the “turnkey” modality. .

In terms of production, the Portuguese factory PROMECEL, Industria de Componentes Mecânicos e Eléctricos Lda is of particular importance. (based in Braga), where most of the nuclear products in the RESUL catalogs are produced. Interconnection with PROMECEL is mutually strategic, and RESUL is responsible for defining the ranges that interest itself, as well as for designing and developing them.

From the beginning, RESUL invested in a strategy of differentiation and globalization. Today, taking into account the changes in the world economy resulting from the pandemic and the recent war in Europe, the company’s strategy points to a total concentration on its “core business”: electrical networks and photovoltaic energy solutions, namely:

• Internal market: total focus and concentration on business with institutional companies in the sector and installers hired by them, as well as companies or investment funds interested in installing photovoltaic power plants for self-consumption.
• External market: systematic monitoring of the main international customers and reinforcement of commercial activity in the markets where the company is well positioned: Angola, Mozambique, Cape Verde, Algeria, Libya, Mauritania, S. Tomé and Príncipe, Benin, Zimbabwe, Burundi and many others more however emerging.
