Specialised Capabilities Across Solar Energy Infrastructure.
Since entering the solar energy sector in 2010, STR POWER has developed extensive experience in photovoltaic installations, delivering integrated infrastructure solutions for solar energy projects of varying scales across Greece and international markets.
Our capabilities span design and engineering, construction, testing, commissioning and maintenance. Our specialist teams and company-owned machinery and equipment enable coordinated project delivery across diverse locations and technical demands - from initial planning through to long-term operation.

Design & Engineering
Our capabilities include technical and financial studies, electromechanical design, cable sizing, voltage drop calculations and the technical documentation required for grid connection applications.
Through careful planning and informed engineering decisions, we lay a solid technical foundation for project delivery. We also provide technical verification and support for material selection and procurement, helping ensure that project requirements are addressed from the outset.

Solar Plant Construction
STR POWER undertakes the construction of photovoltaic plants, combining civil works with the installation of electrical and electromechanical infrastructure. Our capabilities extend to turnkey construction services for utility-scale photovoltaic plants, including medium-voltage (MV) substations for grid connection.
Our construction activities include site preparation, earthworks, excavations, reinforced concrete works, cable trenches and foundations, including concrete-free pile-driven mounting systems where applicable. We also carry out the installation of photovoltaic modules, inverters, transformers, electrical panels and associated cabling, alongside perimeter fencing, CCTV and supporting infrastructure.
Our experience covers both ground-mounted and rooftop photovoltaic installations, incorporating different foundation and mounting solutions, including direct pile driving, concrete piles and predrilling methods. We work with fixed-tilt and tracking structures, as well as string and central inverter configurations, adapting construction methods to the technical requirements of each project.
By coordinating the different construction disciplines and technical requirements, STR POWER supports the methodical execution of solar projects from site preparation through to installation.
To support this coordinated approach, project execution is backed by dedicated on-site personnel, machinery, site facilities and management, alongside off-site project management, project controls and administrative support. Integrated IT and telecommunications infrastructure facilitates coordination between on-site teams and off-site resources, contributing to effective project oversight and operational continuity.
Testing & Commissioning
Our scope includes electrical testing, insulation resistance measurements and current-voltage (I–V) curve testing, together with grid connection works and commissioning procedures. These activities help verify installation performance and support the transition from completed construction to operational solar energy infrastructure.
Solar Plant Maintenance
Depending on contractual arrangements and project requirements, services may include comprehensive maintenance coverage with 24/7 support or targeted interventions for specific operational needs.
These maintenance activities include photovoltaic module cleaning, environmentally responsible vegetation management, inspections of inverters, transformers and combiner boxes, as well as checks of earthing systems and electrical connections. Electrical measurements and performance-related inspections further support the identification of potential issues and the continued reliability of solar installations.
