Solving Madurai's Unique Site Challenges
Intense Arid Sunshine & Thermal Efficiency Drops
High summer ambient temperatures increase photovoltaic cell heat, lowering voltage yield.
We calibrate thermal coefficients in PVsyst and engineer elevated structures with optimal ventilation air gaps.
7-Stage Technical Engineering Process
Requirement & Site Assessment
We collect electrical load data, roof architectural drawings, GPS coordinates, local DISCOM guidelines, and site constraints to establish baseline project parameters.
Solar Resource & Meteorological Modeling
Using Meteonorm and NASA satellite databases, we simulate annual Global Horizontal Irradiance (GHI) and Diffuse Irradiance specific to the site coordinates.
3D Layout & Shadow Path Simulation
We build a millimeter-accurate 3D digital twin of the rooftop or land terrain to simulate year-round shadow paths and optimize array pitch without self-shading.
Electrical Single Line Diagram (SLD)
Our electrical team designs DC string groupings, MPPT mapping, AC/DC combiner boxes, breaker coordination, surge protection, and earthing grid layouts.
Structural Wind Load Validation
We simulate extreme wind pressures (up to 180 km/h) on module mounting structures and roof anchors according to IS 875 (Part 3) to ensure total structural integrity.
CEI Approval Package & BOM Sizing
We compile submission-ready drawing sets, cable sizing sheets, voltage drop calculations, and bill of materials (BOM) tailored to local Gujarat CEI scrutiny.
