The Ministry of New and Renewable Energy (MNRE) has introduced SUNtosh, a WhatsApp-based AI-powered chatbot designed to simplify rooftop solar adoption for Indian households. Launched under the PM Surya Ghar: Muft Bijli Yojana, the assistant provides instant, personalized guidance on solar energy savings, system sizing, and subsidies.

What Is SUNtosh?

SUNtosh is an AI-driven digital assistant that helps users understand their rooftop solar potential within seconds. It is designed to make solar energy information more accessible and easier to understand for everyday consumers.

Through a simple WhatsApp interface, users can:

• Estimate electricity savings from solar panels

• Calculate applicable government subsidies

• Determine ideal rooftop solar system size

• Connect with verified solar vendors

• Receive personalized energy recommendations

How SUNtosh Works

The chatbot is accessible via a QR code and requires only two basic inputs:

• Sanctioned electricity load of the household

• Latest electricity bill

Based on this information, SUNtosh instantly generates:

• Recommended rooftop solar capacity

• Expected reduction in monthly electricity bills

• Estimated long-term savings over the system’s lifetime

This eliminates the need for technical knowledge or manual calculations.

Why SUNtosh Was Introduced

The government aims to install rooftop solar systems in 10 million households under the PM Surya Ghar initiative. However, lack of awareness about costs, savings, and subsidy benefits has often slowed adoption.

SUNtosh addresses this gap by providing:

• Simple, instant guidance in everyday language

• Easy access through WhatsApp, widely used across India

• Transparent breakdowns of costs and benefits

Making Solar Adoption Easier

By removing technical barriers and simplifying decision-making, SUNtosh helps households confidently explore solar energy. It reduces dependence on complex subsidy portals and vendor consultations, making the entire process faster and more user-friendly.

The Bigger Impact

With tools like SUNtosh, the government aims to accelerate clean energy adoption and empower citizens to make informed choices about renewable energy. For millions of households, this could mean lower electricity bills and a shift toward sustainable living.
