Four Core Calculation Engines
Capacity & Layout Modelling
Input land area, irradiance data, module spec, and inverter type — the AI engine outputs optimal DC/AC ratio, string configuration, row spacing, and total installed capacity.
INPUTS
- Land area (ha)
- GHI / DNI irradiance
- Module Pmax & dimensions
- Inverter rated power
OUTPUTS
- Installed capacity (MWp)
- DC/AC ratio
- String count & configuration
- Row spacing & GCR
MV Cable Sizing Engine
Automated medium-voltage cable sizing per IEC 60364 — calculates conductor cross-section, voltage drop, short-circuit current, and thermal rating for every feeder run.
INPUTS
- Feeder length (m)
- Load current (A)
- Ambient temperature
- Installation method
OUTPUTS
- Conductor size (mm²)
- Voltage drop (%)
- Short-circuit rating (kA)
- Cable type recommendation
Transformer Derating Model
IEC 60076-compliant transformer sizing with automatic derating for altitude, ambient temperature, and harmonic loading. Outputs recommended MVA rating and cooling class.
INPUTS
- Total inverter output (MVA)
- Altitude (m)
- Max ambient temp (°C)
- Harmonic distortion (%)
OUTPUTS
- Recommended MVA rating
- Derating factor
- Cooling class (ONAN/ONAF)
- Winding temperature rise
Bill of Materials Generator
Structured BOM with IEC-compliant specifications, quantities, and vendor-agnostic descriptions — ready for procurement tendering and EPC cost estimation.
INPUTS
- Project capacity (MWp)
- Site topology
- Grid connection voltage
- Earthing system
OUTPUTS
- Full BOM line items
- Quantity take-offs
- Spec sheets per item
- CSV / PDF export
