Aliou Amar, a disciple of the Italian professional school, finished a four-week practice under the Erasmus + programme in our company. As a leader in the renewable energy sector we had a pleasure to acquaint Aliou with the latest technological solutions associated with ecological heating systems. He had the opportunity to work with installations of photovoltaic and solar systems, as well as get acquainted with work of a modern drilling machine Geodrill for performing radial drillings for geothermal heat pumps in GRD technology. An important asset of practices in our company for the trainee was furthermore acquire teamwork skills, professional development, as well as improving the social and language competences and learning about the culture and tradition of our country. We hope that the internship in OPTIMA POLSKA let Aliou prepare to practice in the world’s labor markets.
