The Government of India is exploring an advanced digital initiative called the AI-Based Solar Fault Prediction Network (ASFP-2026) that will use machine learning algorithms to predict rooftop solar failures before they occur. Officials involved in the early evaluation stage told SolSetu that the system aims to reduce downtime, prevent safety hazards, and improve rooftop solar performance nationwide.

With over a million new residential installations expected under national solar programs, ensuring system reliability has become a critical priority.

Why ASFP-2026 Is Needed

Current rooftop solar systems frequently experience:

• Sudden inverter shutdowns caused by micro-faults
• Panel mismatch losses that go unnoticed for months
• Loose wiring leading to heat buildup
• Undetected earthing failures
• Hotspot formation on panels due to shading
• MC4 connector failures leading to fire risks

AI-driven predictive models can identify these symptoms early and alert consumers or installers before damage occurs.

Features Under Consideration

The proposed ASFP-2026 platform may include:

• AI algorithms that analyze inverter & panel data every 5 minutes
• Early warning notifications for wiring issues or abnormal heating
• Performance anomaly detection using pattern recognition
• Fault probability score displayed to homeowners
• Predictive alerts for shading, ageing, and DC-side problems
• State-level dashboards for DISCOM monitoring
• Installer service reminders based on fault risk level

The system will work in sync with inverter OEMs and rooftop solar monitoring apps.

Benefits for Consumers

AI-powered fault prediction will help homeowners:

• Reduce inverter & panel failures
• Cut down on system downtime
• Improve long-term generation consistency
• Avoid costly repairs caused by delayed diagnosis
• Ensure safer rooftop installations with early detection of hazards

This marks a major shift toward predictive solar maintenance in India.

Pilot Launch in 2026

The initiative may begin in data-rich states such as:

• Gujarat
• Maharashtra
• Karnataka
• Tamil Nadu
• Delhi NCR

The nationwide rollout will follow after calibrating models across climate zones.

SolSetu will continue covering updates as the ASFP-2026 system moves toward prototype testing.
