MSMEs (Micro, Small and Medium Enterprises) are among the biggest electricity consumers in India’s industrial sector and face electricity costs that significantly impact their competitiveness. Solar power offers MSMEs a path to lower, predictable energy costs. Multiple central and state government schemes support MSME solar adoption, alongside significant tax benefits.

Why solar matters especially for MSMEs

MSMEs typically pay commercial or LT industrial tariffs that are Rs 8 to Rs 14 per unit in most states, significantly higher than domestic rates. For a manufacturing unit consuming 20,000 to 50,000 units per month, electricity is often the second or third largest operating cost.

Rooftop solar reduces this cost predictably over 25 years, insulating the business from tariff increases. The financial return for MSMEs with high daytime electricity consumption is often substantially better than the already-strong residential solar economics.

Central government MSME solar schemes

MNRE rooftop solar programme for commercial and industrial consumers: MNRE has run subsidy programmes targeting commercial and industrial rooftop solar. Check the current scheme status and applicable subsidy rates at mnre.gov.in.

SIDBI solar financing: SIDBI (Small Industries Development Bank of India) has facilitated concessional solar financing for MSMEs through its MSME-focused loan programmes. Check sidbi.in for current solar loan products.

Technology Upgradation Fund Scheme (TUFS): This scheme for the textile industry includes solar energy as an eligible technology. Textile MSMEs should check if the current TUFS version covers solar.

State-level MSME solar schemes

Several states have specific MSME solar incentives beyond the central level:

Gujarat: GEDA has run programmes supporting industrial rooftop solar. The state’s strong solar ecosystem means competitive installer pricing and relatively efficient DISCOM processing for commercial connections.

Maharashtra: MEDA has supported MSME solar in Maharashtra. Combined with MSEDCL’s commercial net metering, the financial case for Maharashtra MSMEs is meaningful.

Tamil Nadu: TEDA and the state’s industrial solar promotion programmes have targeted MSMEs in Tamil Nadu’s large manufacturing base.

Rajasthan: RRECL has promoted solar for industrial consumers in Rajasthan’s industrial estates.

Always verify the current active scheme for your state at the respective state energy agency website.

Accelerated depreciation: the biggest financial benefit for MSMEs

The most significant financial advantage of solar for MSMEs over residential buyers is the accelerated depreciation benefit under Indian income tax law.

Solar energy equipment qualifies for accelerated depreciation at 40 percent under the Income Tax Act (verify current rate as this can change). This means a business investing Rs 50 lakh in solar can claim Rs 20 lakh as depreciation in the first year, reducing its taxable income by that amount.

For a business in the 25 percent corporate tax bracket, this translates to Rs 5 lakh in tax savings in year one alone. Over the depreciation schedule, the total tax benefit can reduce the effective cost of the solar installation by 30 to 40 percent.

This benefit is available only to businesses, not to individual homeowners.

Who is eligible for MSME solar schemes?

For central MSME programmes:
– Registered MSMEs with a valid Udyam registration number
– The business must have an electricity connection in the commercial or industrial category
– The installation must be on the business premises (factory, shop, office)

State schemes have their own eligibility criteria which vary and should be verified at the respective state energy agency.

Net metering for MSME solar

Commercial and industrial connections have access to net metering in most states, but the rules can differ from domestic:

System size limits are generally pegged to the sanctioned load.

Some states have different export compensation rates for commercial consumers compared to domestic.

DISCOMs may have separate application queues and processing times for commercial net metering.

How to apply: MSME solar process

Obtain your Udyam registration if you do not already have one (udyamregistration.gov.in).

Identify applicable central and state schemes and confirm eligibility with the respective agencies.

Get the net metering limit confirmed by your DISCOM for your specific commercial connection.

Obtain three quotes from installers experienced with commercial solar and your DISCOM’s commercial processes.

Apply for net metering through your DISCOM’s commercial solar application process.

Consult your chartered accountant about the accelerated depreciation claim in your annual return.

Typical ROI for MSME solar

A manufacturing MSME in Gujarat consuming 30,000 units per month at Rs 10 per unit spends Rs 3 lakh per month on electricity.

A 100 kW rooftop solar system generates approximately 13,500 to 15,000 units per month. Saving 14,000 units at Rs 10 per unit is Rs 1.4 lakh per month.

System cost: approximately Rs 38 to Rs 45 lakh.
Annual savings: approximately Rs 16.8 lakh.
Payback: approximately 2.3 to 2.7 years before tax benefit.
With accelerated depreciation tax saving of approximately Rs 4 to Rs 5 lakh in year one, effective payback is even shorter.

Summing up

MSME solar in India combines strong electricity savings from high commercial tariffs, multiple subsidy schemes, concessional financing, and the accelerated depreciation benefit into one of the most compelling industrial investments available. The key steps are confirming scheme eligibility, getting DISCOM net metering confirmation, and working with a tax advisor to structure the depreciation benefit.
