Clear answer

Clear answer, explained.

It includes reviewing roof load capacity, surface condition, electrical service limits, shading impacts, and utility interconnection requirements. The assessment produces a technical design, production forecast, and a feasibility summary for installation.


Key points

What this means in practice.

  • Structural review of roof load and engineering limits
  • Roof condition inspection and suitability for installation
  • Electrical service capacity, breaker space, and interconnection review
  • Shading analysis using solar modelling tools
  • Optimal panel layout and system size design
  • Annual energy production forecast

When this applies

Best-fit environments.

  • Commercial buildings considering rooftop solar
  • Sites with older roofs or uncertain structural capacity
  • Warehouses, offices, retail spaces, and mixed-use buildings
  • New builds requiring early feasibility checks
