Electrical (CEIG) Drawings
CEIG electrical drawings for net metering and gross metering solar installations
CEIG DRAWINGS
DISCOM-Ready Electrical Drawings for Solar Approval
We believe that solar is for everyone, whether residential, commercial, or industrial. CEIG drawings are generally needed for grid-connected net metering and gross metering installations, not for off-grid systems. Confirm the exact requirement with your DISCOM.
Heaven Designs prepares accurate CEIG electrical drawings formatted to your state DISCOM's requirements, to reduce back-and-forth during metering approval.

WHY IT MATTERS
Importance of CEIG-Compliant Solar Design
Solar systems connected to the DISCOM grid for net or gross metering require CEIG (Chief Electrical Inspector to Government) approval before energisation. Without proper drawings, your project can face delays, fines, or rejection.
Heaven Designs' engineers prepare drawings that match the format and technical requirements of each state's CEIG office, to cut avoidable revisions.
Heaven Designs has worked with 300+ EPC clients (company figure) on projects from residential rooftops to utility-scale ground mounts. For the approval steps, read our guide to the CEIG drawing approval process in India, the note on DISCOM net metering changes in 2026, and net metering vs net billing. Our comparison of AutoCAD Electrical vs manual SLD drafting covers how the SLD itself is drawn.
