The mission aimed to establish India as a global leader in solar energy by creating policy conditions for rapid technology diffusion across the country.

The core objectives focused on three critical areas: reducing the cost of solar power generation to achieve grid parity, creating favorable conditions for solar manufacturing through research and development, and deploying both grid-connected and off-grid solar applications to address energy security challenges. These objectives were designed to work in tandem, ensuring that as solar capacity expanded, costs would decline and accessibility would improve.

Ambitious targets and phased implementation 🔗

The mission adopted a strategic three-phase approach to achieve its goals. Phase I (2010-2013) targeted 1,000 MW of grid-connected solar plants and 200 MW of off-grid applications. Phase II (2014-2017) aimed for cumulative targets of 4,000-10,000 MW of grid-connected capacity and 1,000 MW of off-grid applications. Phase III (2017-2022) set the ambitious goal of 100,000 MW of cumulative grid-connected solar capacity and 2,000 MW of off-grid applications.

Initially, the mission’s original target was 20 GW of grid-connected solar power by 2022. However, recognizing both the potential and necessity of renewable energy, the government revised this target five-fold to 100 GW in June 2015. This dramatic upscaling demonstrated India’s commitment to renewable energy leadership. The revised target comprised 60 GW from large and medium-scale grid-connected projects and 40 GW from rooftop solar installations.

Beyond electricity generation, the mission set specific targets for solar thermal applications. The goal was to achieve 15 million square meters of solar thermal collector area by 2017 and expand it to 20 million square meters by 2022 for applications like water heating and industrial processes. Additionally, the mission aimed to deploy 20 million solar lighting systems for rural areas by 2022, addressing energy access challenges in off-grid communities.

Milestone achievement and extended timeline 🔗

The mission’s progress exceeded expectations in many areas. India reached the 100 GW solar capacity milestone on January 31, 2025, demonstrating the program’s effectiveness despite timeline extensions. This achievement positioned India among the top five countries globally in installed solar capacity, validating the mission’s strategic approach and implementation mechanisms.

Key initiatives transforming India’s solar landscape 🔗

The National Solar Mission catalyzed multiple innovative initiatives that revolutionized how solar energy is deployed across India. One of the most significant achievements was establishing reverse bidding as the market-oriented procurement mechanism, moving away from fixed feed-in tariffs and capital subsidies. This approach resulted in substantial reductions in solar electricity prices, making solar power increasingly competitive with conventional energy sources.

Solar park development and large-scale projects 🔗

The Solar Park Scheme emerged as a cornerstone initiative, creating specialized zones with dedicated infrastructure for solar project development. Notable achievements include the Bhadla Solar Park in Rajasthan, one of the world’s largest solar installations with capacity exceeding 2,245 MW. Similarly, the Pavagada Solar Park in Karnataka, developed on land leased from farmers, demonstrates innovative approaches to land acquisition while providing farmers with steady income.

The Canal Solar Power Project in Gujarat showcases multifunctional benefits, with solar panels installed over irrigation canals generating electricity while simultaneously reducing water evaporation. This exemplifies how the mission encourages solutions that address multiple challenges simultaneously, maximizing resource efficiency.

Solar thermal applications and water heaters 🔗

The mission actively promoted solar thermal applications beyond electricity generation. Solar water heating systems found widespread adoption in hotels, hospitals, and residential complexes, particularly in southern states. These technologies offer significant potential for reducing electricity and LPG consumption in domestic and commercial establishments. Community solar cookers in institutions like schools and religious establishments further demonstrate the versatility of solar thermal applications.

Off-grid solutions for rural India 🔗

For remote areas where grid extension is economically unviable, the mission supported comprehensive off-grid solutions ranging from basic solar lanterns to sophisticated micro-grids capable of powering entire villages. The Solar Study Lamp Scheme distributed millions of solar-powered LED lamps to students in energy-deficient areas, enabling education after sunset and improving learning outcomes.

Perhaps most transformative has been the PM-KUSUM scheme, which aims to solarize agricultural pumps and establish farmer-owned renewable power plants. This program addresses the critical nexus between energy, water, and food security in rural India, empowering farmers while reducing dependence on grid electricity and diesel.

Economic impact and employment generation 🔗
