India is evaluating a new nationwide rating mechanism called the Solar Vendor Trust Score System (SVTS-2026) to certify and rate solar installers based on service quality, safety practices, complaint history, and consumer satisfaction levels. Senior officials involved in early discussions told SolSetu that the system aims to reduce fraud, improve installation standards, and help consumers choose trustworthy vendors.

With rooftop solar adoption rising sharply, the need for reliable vendor transparency has never been more critical.

Why SVTS-2026 Is Being Considered

Several states have reported increasing consumer complaints regarding:

• Poor system installation quality
• Untrained installers causing safety risks
• Delayed service and warranty failures
• Non-standard wiring and low-quality materials
• Confusion among consumers due to hundreds of new vendors

SVTS-2026 aims to bring nationwide uniformity in rating and accountability.

How the Trust Score System May Work

The proposed rating model will evaluate vendors using:

• Quality Score: based on installation audits
• Safety Score: adherence to BIS & technical guidelines
• Service Score: complaint response, warranty actions
• Customer Satisfaction: verified consumer feedback
• Compliance Score: documentation, certifications, licensing

The score will be displayed publicly through state and national solar portals.

Benefits for Consumers

• Easier selection of reliable vendors
• Reduced risk of poor-quality installations
• Better long-term system performance
• Accountability for vendors & EPC companies
• More transparency in pricing versus quality

Benefits for Genuine Installers

• Higher trust and customer conversions
• Recognition for quality work
• Protection against unqualified competitors

Experts say the move could standardize India’s rooftop solar ecosystem and encourage professionalism within the installer community.

Rollout Expected in 2026

The system may be integrated with:

• State solar portals
• National rooftop subsidy platform
• DISCOM approval systems

A pilot phase is expected across states with the highest rooftop adoption.

SolSetu will continue tracking updates as SVTS-2026 moves into evaluation and consultation stages.
