Photovoltaic Engineering for Rooftop and Ground-Mounted PV
From preliminary design and plant sizing through to detailed electrical engineering and technical support during construction, Varian Energy develops robust planning solutions for commercial rooftop and ground-mounted PV systems.
© MaxSolarEngineering, interfaces and documentation as one system
Every design starts from one consistent technical concept: plant layout, electrical design, protection and metering concepts and the interfaces to the grid connection are developed together and documented in reviewable deliverables.
- Engineering driven by expertise and experience
- Interfaces clearly defined
- Documented for review
Technical scope in detail
The service modules are clearly structured and can be combined to match the project phase, plant configuration and technical requirements.
Plant Concept & Design
The technical basis, established before detailed engineering costs arise.
- Preliminary plant concept
- Plant layout
- Module, string and inverter configuration
- Optimized BESS configuration
- Yield simulation with PVsyst and PV*SOL
- Technical variant assessment
Electrical Engineering
Electrical design developed to construction-ready documentation.
- Single Line Diagram (SLD)
- Cable trench and cable dimensioning
- Support throughout the entire certification process
- Protection and metering concepts
- Approval of plans to be built
