Electrical (CEIG) Drawings
CEIG-compliant electrical design drawings for net metering & 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. Permits and CEI drawings are required only for net metering and gross metering system installations, not for off-grid systems.
Heaven Designs prepares accurate, stamped CEIG electrical drawings that meet state DISCOM requirements, reducing back-and-forth and speeding up your 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 exact format and technical requirements of each state's CEIG office — reducing revisions and getting your project approved faster.
Our CEIG drawing packages are used by 300+ EPC companies across India, covering residential rooftop to utility-scale ground mount installations.
Faster Approvals
State-specific formatting reduces CEIG office revision cycles.
IS Standard Compliant
All drawings follow IS 732, IS 3043, and relevant BIS standards.
Engineer-Stamped
Licensed electrical engineer sign-off included with every set.
Quick Turnaround
3–5 working days from data receipt to complete drawing package.
Revision Support
Free revisions included for CEIG office query responses.
