India’s solar energy journey is often measured in gigawatts, record installations and billion-dollar investments. With over 143 GW of installed capacity by early 2026 and ambitious government programmes accelerating adoption, the country has firmly established itself as a global solar leader. Yet beyond this macro success lies a more grounded question: how is this growth translating for MSMEs and households that still lack reliable 24/7 electricity?
For many small businesses and households across Tier II, Tier IIIand rural India, electricity remains inconsistent. Power outages and voltage fluctuations are common. For MSMEs — such as small manufacturing units, repair shops, or food processors — this leads to lost productivity and revenue. Machines sit idle, orders are delayed and planning becomes difficult. Many rely on diesel generators, which are expensive and polluting.
Households face similar challenges. Unreliable electricity affects lighting, cooling and access to digital services. During peak summers, it impacts health and comfort; for students, it disrupts learning. In both cases, unreliable power imposes a hidden cost – economic for businesses and developmental for households.
In this context, solar energy offers a compelling solution. Decentralised systems, particularly rooftop solar paired with storage, can provide reliable and cost-effective power. MSMEs can reduce energy costs and improve business continuity, while households gain dependable access to electricity, improving quality of life.
Yet adoption at the grassroots level remains slower than expected. The issue is not technology; it is access.
The most immediate barrier is upfront cost. Even as prices fall, installing a solar system requires significant initial investment, especially with battery storage. For MSMEs operating on tight margins and for low- to middle-income households, this remains a major hurdle.
Closely linked is the challenge of financing. Access to affordable credit is limited, particularly for informal businesses. Financial institutions often perceive small borrowers as high-risk, and tailored financing products for decentralised solar are still evolving. As a result, many who would benefit most are unable to adopt.
Awareness and trust gaps also persist. Many potential users are unaware of subsidies or do not fully understand long-term savings. Concerns around quality, installation, and after-sales service further slow decision-making.
Execution challenges compound the issue. In smaller towns, access to skilled installers and reliable service providers is uneven. Poor installation or lack of maintenance support can undermine performance and trust.
While government initiatives have driven growth, implementation gaps remain – delays in subsidies, administrative complexity, and inconsistent state-level policies make adoption harder than it should be.
Addressing these challenges requires a shift – from scaling capacity to enabling access. Innovative financing models such as pay-as-you-go systems, leasing, and blended finance can lower entry barriers. Financial institutions and fintech players can design products suited to MSMEs’ realities – irregular incomes and limited collateral.
The private sector has a critical role in building last-mile distribution and service networks. Training local entrepreneurs as solar providers can improve installation quality, ensure maintenance, and build trust – while also creating jobs.
For schools and educational institutions, solar offers a transformative opportunity. Reliable electricity enables digital learning, improves classroom conditions, and extends study hours. Targeted programmes — supported by government, philanthropy, and the private sector — can prioritise solar access for underserved schools, linking energy access directly to educational outcomes.
Government can further support adoption by simplifying processes, ensuring timely subsidy disbursement, and creating consistent policies across states. More importantly, programs should focus on outcomes – ensuring solar adoption translates into better livelihoods, incomes, and learning.
India’s solar story is at an inflection point. The next phase will not be defined by how much power is generated, but by how effectively it reaches those who need it most. For MSMEs and households, solar is not just about clean energy – it is about reliability, affordability, and the ability to build more secure futures.
