PV Engineering
Photovoltaic installations require rigorous engineering, tailored to the specificities of your projects, to ensure performance, compliance, and durability. At TEWA, we model and validate every component of your installations to ensure cutting-edge design. Our engineers can intervene at each stage of the project lifecycle: electrical sizing, structural studies, performance modeling, and construction support.
AC & DC sizing
We size all electrical networks for your projects.
Comprehensive studies for optimal AC & DC architectures
Precise AC & DC cable sizing using certified software such as LisePV
Selectivity and protection coordination studies performed with LisePV
Grid connection and impact studies, as well as complete MV and HV system design, in coordination with utilities
Plans & diagrams
We produce all types of plans and diagrams, compliant with applicable standards for your projects.
AC/DC single-line diagrams for LV, MV, and HV networks
Electrical layout and architecture plans, including layouts and cable routing
Control, protection, and supervision diagrams for control logic and SCADA interfaces tailored to your needs
Construction packages including plans and technical specifications for your site teams
Modeling & optimization
We simulate and optimize your projects to maximize energy production and increase the profitability of your installations.
Energy yield simulation using PVsyst modeling
Layout optimization based on 3D analysis and shading studies
CAPEX and LCOE analysis to validate your technical choices
3D visualizations for realistic and impactful renderings
Repowering & revamping
We modernize your existing solar plants to improve their reliability, performance, and extend their lifespan.
Complete technical, electrical, and mechanical audit of your existing installations.
Performance analysis and comparison between actual and expected production, with improvement recommendations.
Equipment resizing and compatibility verification to maximize production.
Structural & civil analysis
We carry out the structural and civil engineering studies necessary for your projects.
Static and dynamic load calculations for structures and foundations.
Cut-and-fill and grading studies to optimize earthworks according to topography.
Optimal foundation design according to geotechnical constraints.
Calculation notes and structural plans required for obtaining your permits.
Project support
We support you at every stage of your projects, from design to operation.
Technical support during construction phase such as plan adaptation, drafting of technical specifications and tender documents.
Quality control and inspections to ensure compliance with plans and local standards.
Documentation support and project handover: preparation of deliverables and support until client handover.
