Solving Hubballi-Dharwad's Unique Site Challenges
Heavy Foundry Electrical Noise & Induction Harmonics
Foundry arc furnaces and machining units in Gokul Road cause significant line harmonics that can trip solar inverters.
We engineer CEIG-approved SLDs specifying inverters with wide MPPT windows, active harmonic filtering, and robust surge protection devices (SPDs).
High Wind Loads on the North Karnataka Deccan Plateau
The elevated open plateau terrain around Belur Industrial Area experiences strong seasonal crosswinds up to 155 km/h.
We validate all structural mounting arrays using STAAD.Pro simulations adhering to IS 875 (Part 3) standards, specifying reinforced purlin anchors.
HESCOM Feeder Interconnection & Protection Protocols
Connecting multi-hundred-kilowatt arrays to HESCOM 11kV/33kV distribution networks requires specialized protection coordination.
Our electrical blueprints include numerical relay coordination curves, earth grid step-and-touch calculations, and comprehensive statutory submittal documentation.
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.
