Use Official Portal Data As The First Filter
UPNEDA rooftop portal listings publicly show vendor identifiers and registration details. For example, AR SAURTECH ENERGY PVT LTD appears with firm code DLI2403150602 in approved-firm snapshots.
This is a helpful transparency layer, especially for first-time buyers comparing multiple installers.
Follow With Technical Due Diligence
Approval status should be followed by project-level checks: structural design quality, inverter strategy, AC/DC safety, and commissioning documentation standards.
Ask for examples from nearby districts because local utility and inspection processes can vary even within the same state.
Finalize With A Decision Framework
Shortlist at least three vendors and score each on engineering depth, response quality, delivery transparency, and after-sales commitments.
This approach reduces decision bias toward only price and improves long-term system reliability outcomes.
How to apply this in your next project
For your next rooftop solar project, align these recommendations with clear scope, design freeze checkpoints, and execution ownership so submissions and approvals move faster with fewer revision cycles.
Quick FAQ
