⚠️ Technical Notes & Assumptions
  • Static Installation: Defined as fixed-tilt systems with central string inverters, basic monitoring (if any), and no advanced grid interconnection capabilities.
  • Smart Installation: Includes module-level power electronics (MLPE), advanced inverters with grid services, AI-based monitoring, tracking systems (where applicable), and full communication stack.
  • Energy yield improvements are site-specific and depend on latitude, shading conditions, and system design.
  • Cost figures are representative of utility-scale installations (>1 MW) in developed markets as of 2024.
