India's Solar Surge: Nation Poised for Global Second-Largest Market by 2026

India is on an aggressive path to reshape its energy landscape, with projections placing it as the world's second-largest solar market by 2026. This ambitious growth trajectory, according to the National Solar Energy Federation of India (NSEFI), is fueled by robust domestic policy support and unprecedented solar capacity additions.

The sector has demonstrated remarkable momentum, marking a significant acceleration in its expansion rate. India successfully added 50 GW of solar capacity within just 14 months, achieving the major milestone of 150 GW.

This pace marks a substantial improvement over historical growth. It contrasts sharply with the eleven years required to reach the initial 50 GW, and the nearly three years needed to scale up to 100 GW.

Scaling Capacity Towards 2030 Targets​

NSEFI experts project that India's solar energy capacity will reach 280–300 GW. This massive expansion is crucial for supporting the nation’s larger goal of achieving 500 GW of non-fossil capacity by 2030.

Maintaining the current rapid addition rate means India is quickly aligning with this ambitious national goal. Industry leaders note that the potential for solar capacity to exceed these projections is considerable.

This potential expansion is anchored by major governmental initiatives. Key programs like PM Surya Ghar, upcoming PM KUSUM 2.0, dedicated floating solar policies, and the National Green Hydrogen Mission will drive demand over the next four years.

Driving Growth Through C&I and Distributed Energy​

The primary catalysts for India’s next phase of clean energy growth are identified as Distributed Renewable Energy (DRE) and Commercial & Industrial (C&I) sector adoption.

The C&I segment has rapidly surpassed expectations, achieving double-digit annual installations of nearly 10 GW for the first time. Industry observers believe this is only the beginning of a major shift in energy sourcing.

Policy frameworks are proving essential in unlocking this demand. Mechanisms such as Green Energy Open Access, Virtual Power Purchase Agreements (VPPAs), and the Renewable Consumption Obligation (RCO) framework are providing significant market impetus.

These utility-scale policy enablers are expected to allow C&I capacity additions to rival those generated under traditional utility-led PPAs within the next two years.

Furthermore, flagship government programs have significantly bolstered DRE adoption. Currently accounting for nearly 20 per cent of installed solar capacity, NSEFI projects this share will grow substantially, reaching 35 per cent by 2030.

Building Self-Reliance in Manufacturing and Storage​

On the manufacturing front, India is making considerable strides toward self-reliance. The implementation of Production-Linked Incentive (PLI) schemes, the Approved List of Models and Manufacturers (ALMM), and Basic Customs Duty (BCD) measures have bolstered domestic capabilities.

The focus is now shifting to strengthening upstream supply chains. Experts emphasize that the next wave of growth will hinge on developing robust domestic capabilities for wafers, ingots, polysilicon, and quartz.

Looking beyond solar generation, energy storage is identified as a critical component of India’s integrated clean energy future. The NSEFI forecasts that the country will achieve double-digit energy storage capacity within the next 18 months.

Policy interventions, including viability gap funding (VGF) and provisions for non-solar hour connectivity, have created a strong foundation. This acceleration in storage deployment is anticipated over the next 12 to 18 months.
