Solar Subsidy State-Wise Guide in India (2026)

Rooftop solar has become far more affordable in India, thanks to central and state subsidies. Yet many homeowners still feel confused about how much support they actually get and who provides it. After working with residential solar projects for over a decade, I’ve seen one pattern clearly: people who understand subsidies early save the most money.

This guide breaks down how solar subsidy works in India and what you can expect in different states in 2026.

How Solar Subsidy Works in India

India follows a central subsidy model under the PM Surya Ghar scheme. The subsidy is mainly available for residential rooftop solar systems installed through approved vendors.

Central Government Subsidy (2026)

For most Indian homes:

• Up to 2 kW: ~₹30,000 per kW

• 2–3 kW: Additional ~₹18,000 per kW

• Maximum subsidy: ₹78,000 per household

The amount is credited directly to the homeowner’s bank account after installation and

inspection.

State-Wise Solar Subsidy Snapshot

State policies mostly follow the central scheme, but DISCOM rules and speed of approval vary.

Karnataka

• Follows central subsidy structure

• Net metering widely available

• Good approval timelines in cities like Bengaluru

• DISCOM: BESCOM / others

✅ Overall: Solar-friendly state

Maharashtra

• Central subsidy applicable

• Net metering allowed for residential users

• Approval timelines moderate

• DISCOM: MSEDCL

⚠️ Watch: paperwork delays in some regions

Tamil Nadu

• Central subsidy available

• Net metering permitted

• Growing rooftop adoption

• DISCOM: TANGEDCO

✅ Overall: Stable policy environment

Gujarat

• One of the most solar-friendly states

• Fast subsidy processing

• Strong rooftop adoption

• DISCOM: UGVCL / PGVCL / others

⭐ Overall: Best-performing state for residential solar

Uttar Pradesh

• Central subsidy applicable

• Net metering available but slower approvals

• DISCOM: UPPCL

⚠️ Watch: longer processing times

Other Important States (Quick Guide)

Delhi

• Extra state incentive around ₹2,000/kW (limited cap)

• Additional generation incentive per unit

• Strong net-metering support 👉 Best for: apartments and urban homes

Rajasthan

• Offers dual benefit (central + state subsidy)

• Net metering widely available

• High solar potential → fast payback👉 Best for: independent houses with big roofs

Kerala

• Subsidy mainly via central scheme (PM Surya Ghar)

• State agencies handle approvals

• Good adoption in residential sector👉 Best for: homes with high electricity bills

Assam

• State support can reach ~40% of system cost (varies)

• Implemented through AEDA👉 Best for: early adopters in Northeast

Goa

• Subsidy often 40–50% for small systems

• Limited but attractive residential programs👉 Best for: villas and holiday homes

Uttarakhand

• Top-up subsidy available via UREDA

• Good solar potential in plains👉 Best for: small residential rooftops

Note : Subsidy rules change frequently. Always verify with your local DISCOM or state renewable agency before applying.

Real Cost After Subsidy (Example)

Let’s take a typical 3 kW home system in 2026:

• System cost: ~₹1.65 lakh

• Central subsidy: ~₹78,000

• Net cost: ~₹87,000

For most homes, payback happens in 3–5 years depending on usage.

Who Is Eligible

You usually qualify if:

• You own a residential property

• You install rooftop solar through an approved vendor

• You have a valid electricity connection

• You apply through the national solar portal

Commercial buildings do not receive this subsidy.

Common Mistakes Homeowners Make

From field experience, these are the biggest errors:

• Installing through non-approved vendors

• Not checking DISCOM net metering limits

• Ignoring roof shadow analysis

• Expecting instant subsidy release

• Choosing cheapest panels over reliable brands

Avoid these, and your solar journey becomes smooth.

Expert Tip

If your monthly electricity bill is above ₹2,000, rooftop solar with subsidy usually makes financial sense in India today. The earlier you install, the faster you lock in savings against rising power tariffs.

Final Take

Solar subsidies in India have made smart homes far more accessible. While the central benefit is largely uniform, your real experience depends heavily on your state DISCOM and installer quality. Plan carefully, choose approved vendors, and rooftop solar can become one of the highest-return upgrades for your home.
