The real reason MSMEs aren’t going big on rooftop solar in India

Operational alignment that works in favor of solar

MSMEs are naturally aligned with how solar power is generated and consumed. Most units operate during daytime hours, allowing rooftop solar for MSMEs to directly offset grid electricity use without requiring storage or load shifting. This improves utilization and makes decentralized solar operationally relevant for the sector.

MSMEs also account for a significant share of industrial electricity demand, making them an important segment for India’s clean energy transition.

Cost pressure that makes solar financially compelling

Electricity is a major operating cost for MSMEs -

• Electricity costs account for 5–20% of operating expenses for MSMEs ORF, via Outlook Business)
• In energy-intensive clusters, this can rise to 20–40% (Source: PHDCCI)
• MSMEs consume a large share of industrial energy demand (Source: Roadmap for Green Transition of MSMEs, Niti Aayog)
  

This makes even small reductions in electricity costs financially meaningful. For many businesses, solar becomes less of a sustainability decision and more of a cost optimization strategy.

Unit economics with immediate savings

The economics of solar remain compelling -

• Rooftop solar tariffs: ₹3.8–₹6.5 per kWh (Source: Solar now)
• Grid tariffs: ₹5.6–₹9.9 per kWh (Source: Solar now)
  

This creates potential savings of ₹2–₹4 per unit, making SME solar solutions in India an attractive option for businesses operating on tight margins. Over time, these savings compound into meaningful cost reductions and improved competitiveness.

Large opportunity, limited adoption

Despite strong economics and operational alignment, adoption remains low.

• MSMEs hold an estimated 15–18 GW of untapped rooftop solar potential (Source: Horizon Renewable Power)
• Less than a fraction of this potential has been utilized due to financing and adoption barriers
  

MSMEs consume roughly half of industrial electricity while offering significant rooftop potential, yet deployment remains disproportionately low. This highlights the gap between the business case for rooftop solar for MSMEs and actual implementation.

Stronger cost competitiveness and healthier margins

For MSMEs, the impact of solar begins with the balance sheet.

• Lower operating costs
• Improved competitiveness
• Reduced exposure to tariff volatility

For businesses operating on thin margins, even modest savings can create a meaningful advantage. This is where solar for small businesses in India moves beyond efficiency and becomes a competitive lever.

Measurable emissions reduction and ESG alignment

The environmental benefits are equally significant.

• MSMEs collectively contribute substantially to industrial emissions
• Rooftop solar reduces dependence on fossil-fuel-based electricity
• Solar adoption supports broader sustainability and climate goals

As supply chains increasingly prioritize sustainability, SME solar solutions in India can also strengthen long-term business relevance.

Accelerating India’s renewable energy ambitions

India is targeting 500 GW of non-fossil fuel capacity by 2030, with solar playing a central role.

• MSMEs hold 15–18 GW of untapped rooftop solar potential
• Unlocking this capacity can strengthen decentralized generation
• Wider adoption can help bridge the gap between targets and deployment
  

This makes MSME solar adoption in India important not only for businesses, but for the country’s energy transition.

Cluster-level transformation and industrial resilience

The greatest impact may emerge at the cluster level. Industrial hubs such as textile parks, foundries, and food-processing zones can benefit through -

• Shared infrastructure and aggregation models
• Lower collective energy costs
• Improved reliability and resilience
  

India added more than 5 GW of rooftop solar capacity in FY2025, highlighting growing momentum in decentralized energy adoption. If MSMEs participate at scale, they could become one of the strongest drivers of India’s clean energy transition. (Source: JMK Research, Annual India Solar Report Card FY2025).

Tata Power's strength lies in its ability to operate across the entire solar value chain, from manufacturing and financing support to installation and maintenance.

A scaled, proven C&I and rooftop portfolio

Today, Tata Power has built one of India's largest rooftop solar portfolios -

• 3.6 GWp of rooftop solar capacity
• Nearly 3 GWp in the C&I segment
• More than 1.5 lakh rooftop installations
• Presence across 700+ cities
• Serving over 2.5 lakh customers

This positions Tata Power as a provider that understands the operational realities of businesses across industries and scales.

Solutions designed around MSME realities

Tata Power has focused on addressing one of the biggest barriers to MSME solar adoption in India: financing.

• Partnerships with institutions such as SIDBI support collateral-free financing opportunities
• Structured financing schemes help reduce entry barriers
• Turnkey execution models simplify project deployment

As Dr. Praveer Sinha, CEO & MD, Tata Power, noted - "MSMEs are the backbone of India's economy. They operate across industrial segments and are major consumers of electricity. Our strategic collaboration with SIDBI will facilitate the ease of opting for renewable energy in the MSME sector and power its quest to become more efficient and globally competitive."

Simplifying adoption through end-to-end delivery

For many MSMEs, complexity can be a bigger challenge than technology itself.

Tata Power helps reduce that complexity through -

• Site assessment and system design
• Installation and commissioning
• Regulatory approvals
• Operations and maintenance support

Trust and execution capability are often decisive factors for businesses evaluating rooftop solar for MSMEs, and end-to-end delivery helps reduce both risk and effort.
