HOW IT WORKS
From Approved Concept to Construction Drawings
Post-design starts once the client has signed off the concept layout. From there, the job is to turn that layout into a package the site team can build without guessing.
- Inputs: the approved pre-design layout, final module and inverter selections, site survey data, and roof or land structural details.
- Drawings: detailed array layouts, string and cable layouts, earthing layouts and single-line diagrams.
- Calculations: structural checks for the mounting structure and foundations, plus cable sizing.
- Approvals and handover: CEIG electrical drawings for Indian projects, permit documentation, and an as-built set at close-out.
