Growth and Present Position
Solar energy has emerged as the largest component of India’s renewable-energy capacity.
As of 30 June 2026, India had about 162.15 GW of installed solar capacity, comprising:
- about 121.25 GW of ground-mounted solar;
- about 30.11 GW of grid-connected rooftop solar;
- about 4.36 GW of solar capacity in hybrid projects;
- about 6.43 GW of off-grid solar.
Solar power has expanded rapidly because of falling technology costs, competitive bidding, large solar parks, rooftop installations and supportive government policies.
Major Programmes
National Solar Mission
It provides the broad policy framework for large-scale expansion of solar power and development of domestic solar capabilities.
PM Surya Ghar: Muft Bijli Yojana
It promotes rooftop solar for residential households through central financial assistance and concessional financing. By July 2026, nearly 48 lakh households had benefited from the programme.
It promotes:
- standalone solar agricultural pumps;
- solarisation of existing grid-connected pumps;
- decentralised solar plants.
Solar Parks Scheme
Large solar parks provide common land, transmission and infrastructure facilities to reduce project-development risks.
India is also promoting floating solar, solar-wind hybrid projects and solarisation of public infrastructure.
Advantages and Importance
Solar energy can contribute to:
- reduction in fossil-fuel dependence;
- lower greenhouse gas emissions;
- diversification of electricity supply;
- decentralised power generation;
- electricity access in remote areas;
- reduction in agricultural diesel use;
- employment in manufacturing, installation and maintenance.
Rooftop solar allows electricity to be generated close to the point of consumption and can reduce transmission losses.
Solar power also strengthens energy security because sunlight is a domestic and widely available resource.
Major Challenges
Solar generation is intermittent and varies with sunlight, weather and time of day. Large-scale integration therefore requires storage and flexible electricity systems.
Other challenges include:
- land acquisition for large projects;
- transmission constraints;
- dependence on imported cells, wafers and critical materials;
- financial weakness of electricity distribution companies;
- recycling of old solar modules;
- ecological impact of large solar parks;
- variability in rooftop adoption across states;
- need for affordable battery storage.
Solar manufacturing also requires energy, minerals and industrial processing, so solar power is low-carbon rather than completely impact-free.
Future Direction
India must move from simply adding solar capacity towards creating a complete domestic solar ecosystem.
Important priorities include:
- expansion of battery and pumped-storage capacity;
- strengthening Green Energy Corridors;
- domestic production of cells, wafers and modules;
- promotion of rooftop and decentralised solar;
- development of solar-wind hybrid projects;
- recycling and circular-economy standards for panels;
- improved forecasting and grid management;
- protection of ecologically sensitive land;
- greater research into high-efficiency solar technologies.
Conclusion
Solar energy has become central to India’s electricity transition and energy security. Its next phase will depend not only on expanding installed capacity, but also on developing storage, transmission, domestic manufacturing and environmentally responsible deployment.
