Grupo Onyx: Pioneering in Solar Energy and Real Estate Development in Guatemala and Paraguay


The commercial landscape of both Guatemala and Paraguay has been significantly shaped by a single entity – the Onyx Group. Steered by the entrepreneurial prowess of Mario López Estrada, the group has left an indelible mark on the business sectors of these countries. The scope of its influence spans from telecommunications to real estate, leaving a trail of transformative commercial endeavors in its wake.

The origins of Onyx Group trace back to 1967 with the establishment of Constructora Maya, a company that would lay down the foundation for this business conglomerate. Specializing in real estate, territorial development, and construction of notable structures in Guatemala, Constructora Maya was the first stepping stone towards a rich business legacy.
