What is the Jawaharlal Nehru National Solar Mission

The Jawaharlal Nehru National Solar Mission (JNNSM), launched in 2010 under India’s National Action Plan on Climate Change, is one of the country’s biggest renewable energy initiatives focused on expanding solar power generation and reducing dependence on conventional energy sources. The mission promotes grid-connected solar plants, rooftop solar systems, off-grid applications, and domestic solar manufacturing across India. Initially targeting 20 GW solar capacity by 2022, the mission was later expanded to support India’s revised 100 GW solar energy target. People learning how a solar inverter works can better understand the role of solar infrastructure in India’s clean energy transition.

The National Solar Mission focuses on increasing renewable energy adoption, strengthening solar infrastructure, and improving India’s long-term energy sustainability through large-scale solar power expansion.

• Expand solar power generation across India: JNNSM aims to increase solar electricity generation through large-scale grid-connected solar plants, rooftop installations, and decentralised renewable energy systems across urban and rural regions.
• Reduce dependence on fossil fuel-based energy sources: The mission encourages cleaner energy adoption to reduce reliance on conventional electricity generation methods that contribute to pollution and long-term environmental impact.
• Promote rooftop and off-grid solar systems: JNNSM supports rooftop solar adoption for homes, businesses, institutions, and rural communities to improve energy accessibility and distributed power generation.
• Strengthen domestic solar manufacturing capabilities: The mission encourages local manufacturing of solar panels, renewable energy components, and related infrastructure to improve India’s renewable energy ecosystem.
• Support India’s climate and sustainability goals: Increased solar energy usage helps reduce carbon emissions while supporting India’s long-term clean energy and environmental commitments.

The Jawaharlal Nehru National Solar Mission was implemented in multiple phases with progressively increasing solar generation targets and renewable energy infrastructure goals.

• Phase 1 focused on early solar infrastructure development (2010–2013): The first phase targeted around 1,100 MW of solar capacity while introducing policy frameworks, pilot projects, and renewable energy investment support mechanisms.
• Phase 2 accelerated solar expansion and rooftop adoption (2013–2017): The second phase focused on expanding solar generation capacity, supporting rooftop solar projects, and increasing grid-connected renewable energy infrastructure nationwide.
• Phase 3 focused on scaling India’s revised 100 GW solar target: The final expansion phase concentrated on accelerating large-scale solar deployment, manufacturing growth, and renewable energy investments to support India’s revised national solar capacity goals.
• Rooftop and decentralised solar systems received major policy support: Across all phases, the mission encouraged rooftop solar installations, rural electrification projects, and decentralised clean energy solutions for wider accessibility.
• Renewable energy policy reforms continued alongside infrastructure growth: JNNSM also contributed to long-term policy development, financing support, and investment incentives for India’s growing renewable energy sector.

The Jawaharlal Nehru National Solar Mission combines policy support, rooftop solar expansion, manufacturing incentives, and renewable energy infrastructure development to accelerate solar adoption.

India has significantly expanded solar energy infrastructure under JNNSM, making the country one of the world’s fastest-growing renewable energy markets.

• India crossed major solar capacity milestones: The country achieved significant growth in installed solar power capacity through large-scale solar parks, rooftop projects, and renewable energy infrastructure expansion.
• Rooftop solar adoption increased across residential and commercial sectors: The mission supported growing rooftop solar installations for homes, offices, industries, educational institutions, and commercial buildings across multiple Indian states.
• Domestic solar manufacturing expanded considerably: Increased investment in local solar manufacturing improved production capacity for solar modules, renewable energy equipment, and related infrastructure components.
• Renewable energy investments continued to grow strongly: JNNSM encouraged both domestic and international investment in solar infrastructure, financing models, and large-scale renewable energy projects.
• India strengthened long-term clean energy goals beyond 2026: The mission continues to support future renewable energy expansion and broader sustainability targets aimed at improving India’s long-term energy transition.
