Top 10 States in India with the Highest Solar Power

India's solar sector has moved well beyond a handful of large solar parks. From utility-scale projects in desert regions to rooftop installations in densely populated states, solar power is now a major part of India's electricity system.

As of January 2026, India had around 140.61 GW of installed solar capacity, according to data sourced from the Ministry of New and Renewable Energy (MNRE). Ground-mounted projects account for most of this capacity, while rooftop, hybrid and off-grid solar are also contributing to the national total.

But which states are actually leading the country?

This ranking looks at the total installed solar power capacity by state, rather than solar potential alone. The figures include ground-mounted solar, rooftop solar, solar components in hybrid projects and off-grid solar.

Top 10 states by installed solar power capacity

Rank	State	Solar capacity, January 2026
10	Haryana	2.54 GW
9	Uttar Pradesh	3.83 GW
8	Telangana	5.07 GW
7	Madhya Pradesh	5.86 GW
6	Andhra Pradesh	6.94 GW
5	Karnataka	10.82 GW
4	Tamil Nadu	11.73 GW
3	Maharashtra	19.11 GW
2	Gujarat	26.91 GW
1	Rajasthan	37.93 GW

Let's count down from number 10.

10. Haryana — 2.54 GW

Haryana enters the top 10 with approximately 2.54 GW of installed solar capacity as of January 2026.

What makes Haryana particularly interesting is the composition of its solar capacity. Unlike states where utility-scale solar dominates overwhelmingly, Haryana has a relatively substantial contribution from rooftop and off-grid installations.

The January 2026 figures show approximately:

0.27 GW of ground-mounted solar
1.12 GW of rooftop solar
1.15 GW of off-grid solar

That gives Haryana a different solar profile from the large solar-park states further up this list.

The state's agricultural economy also creates opportunities for decentralised solar applications, including solar-powered pumps and other distributed energy systems.

For homeowners and businesses, this is a useful reminder that solar growth isn't measured only by massive solar parks. Thousands of smaller installations can collectively become a significant part of a state's capacity.

9. Uttar Pradesh — 3.83 GW

Uttar Pradesh ranks ninth with around 3.83 GW of installed solar capacity.

Its position is notable because of the state's enormous population, large electricity demand and growing interest in distributed renewable energy.

The January 2026 breakdown includes approximately 2.79 GW of ground-mounted solar, 0.68 GW of rooftop solar and 0.36 GW of off-grid solar.

Uttar Pradesh is also seeing substantial household participation in India's rooftop solar push. By January 10, 2026, the state had recorded more than 3.35 lakh installations under the PM Surya Ghar programme, according to data analysed by PRS India.

That combination matters.

Large solar projects can add capacity quickly, but rooftop adoption brings solar generation closer to where electricity is consumed. As residential awareness improves, states with large housing markets could see rooftop solar become an increasingly important part of their energy mix.

8. Telangana — 5.07 GW

At number eight is Telangana, with approximately 5.07 GW of installed solar capacity.

The state has built a strong position in utility-scale solar, with about 4.36 GW of ground-mounted capacity in the January 2026 figures.

Rooftop solar contributes another 0.70 GW, while hybrid and off-grid additions remain comparatively small.

Telangana's strong solar position is partly connected to its favourable solar resource and the expansion of large renewable-energy projects.

There is another lesson here for states pursuing solar growth: utility-scale projects can establish substantial capacity quickly, but rooftop solar provides a separate avenue for households, commercial buildings and institutions to participate in the transition.

7. Madhya Pradesh — 5.86 GW

Madhya Pradesh takes the seventh position with approximately 5.86 GW of installed solar capacity.

The state has developed several large solar projects and has become an important location for utility-scale renewable energy.

Of its January 2026 capacity, around:

4.93 GW was ground-mounted
0.82 GW was rooftop
0.10 GW was off-grid

Madhya Pradesh is a good example of how land availability can support large-scale solar development.

For utility projects, land is a major consideration. For residential systems, the equation is completely different. A homeowner does not need acres of land; the limiting factors are usually usable roof area, shading, orientation, structural suitability and electricity consumption.

That distinction becomes increasingly important as India's solar story shifts from large projects toward a combination of utility-scale and distributed generation.

6. Andhra Pradesh — 6.94 GW

Andhra Pradesh ranks sixth with about 6.94 GW of installed solar capacity.

The state has approximately 6.09 GW of ground-mounted solar, alongside 0.76 GW of rooftop capacity and smaller contributions from off-grid systems.

Andhra Pradesh has long been considered an attractive market for renewable-energy development because of its solar resource, available land and established large-scale projects.

The state is also seeing significant household interest in rooftop solar. PRS India reported more than 87,000 installations under PM Surya Ghar by January 10, 2026, with more than 90,000 households covered.

The broader trend is clear: India's solar capacity is increasingly coming from two very different models.

One is the large solar farm supplying electricity at scale. The other is a rooftop system producing power close to the consumer.

Both matter.

5. Karnataka — 10.82 GW

Karnataka crosses the 10 GW mark, ranking fifth with approximately 10.82 GW of installed solar capacity.

The state's January 2026 capacity included:

9.76 GW ground-mounted
0.81 GW rooftop
0.21 GW solar capacity within hybrid projects
0.04 GW off-grid

Karnataka's solar growth has been supported by strong utility-scale development as well as increasing distributed generation.

The state also illustrates an important point about installed capacity: having more solar capacity does not automatically mean every household is equally well suited to solar. Actual rooftop performance depends on the individual site.

A good residential assessment should examine roof orientation, shading throughout the day, available area, electricity consumption, inverter sizing and the condition of the electrical system before the final system design is approved.

For homeowners, the quality of the installation process can therefore be just as important as the headline capacity of the state they live in.

4. Tamil Nadu — 11.73 GW

Tamil Nadu comes in fourth with approximately 11.73 GW of installed solar capacity.

The state has around 10.32 GW of ground-mounted solar, 1.34 GW of rooftop solar and a smaller off-grid contribution.

Tamil Nadu has a particularly strong renewable-energy history, and its solar development sits alongside substantial wind capacity.

That combination makes the state an important example of how different renewable sources can complement one another. Solar generation is strongest during daylight hours, while wind generation can follow a different production pattern depending on season and weather conditions.

For households considering rooftop solar, this broader grid-level picture is useful. Solar does not have to work alone. A well-designed system works within the existing electricity network, with the inverter, meter and applicable grid-connection arrangements forming part of the overall installation.

3. Maharashtra — 19.11 GW

Maharashtra takes the third position with an impressive 19.11 GW of installed solar capacity.

Its January 2026 total consisted of approximately:

12.15 GW ground-mounted solar
5.02 GW rooftop solar
1.93 GW off-grid solar

The state's rooftop contribution stands out.

With a large urban population, extensive commercial activity and millions of buildings with electricity demand, Maharashtra has considerable scope for distributed solar.

Recent market data also shows strong rooftop activity in the state. In March 2026, Maharashtra recorded the highest monthly rooftop solar addition among states, at about 221.1 MW, according to JMK Research.

This is significant because rooftop solar solves a different problem from large solar parks. Instead of generating electricity far away and transmitting it to consumers, rooftop systems produce electricity at or near the point of use.

That can make rooftop solar particularly relevant for homes, offices, factories, schools and other buildings with suitable roof space.

2. Gujarat — 26.91 GW

Gujarat is India's second-largest state by installed solar capacity, with approximately 26.91 GW as of January 2026.

Its capacity includes:

19.00 GW ground-mounted solar
6.56 GW rooftop solar
1.17 GW solar capacity in hybrid projects
0.17 GW off-grid solar

The state's rooftop figure is especially striking. More than 6.5 GW of rooftop solar places Gujarat far ahead of most other states in distributed solar capacity.

Household adoption has also been significant. PRS India reported that Gujarat had more than 5.24 lakh PM Surya Ghar installations by January 10, 2026, with more than 7.57 lakh households covered.

Gujarat's experience shows what can happen when large-scale projects and residential solar grow alongside one another.

For the homeowner, however, a state's impressive solar ranking should not be taken as proof that every installation will perform equally well. A poorly positioned rooftop can underperform even in a state with excellent solar resources.

Site-specific design still wins.

1. Rajasthan — 37.93 GW

And finally, at number one, Rajasthan stands well ahead of every other Indian state with approximately 37.93 GW of installed solar capacity as of January 2026.

Its capacity included:

33.06 GW ground-mounted solar
2.06 GW rooftop solar
1.98 GW solar capacity in hybrid projects
0.82 GW off-grid solar

Rajasthan's dominance is largely driven by its enormous utility-scale solar development.

Its geography offers extensive areas suitable for large solar installations, while high solar irradiation supports strong generation potential.

The state's lead has continued into 2026. Recent reporting based on MNRE data indicates that Rajasthan's total renewable-energy capacity crossed 50 GW, with solar accounting for more than 44 GW in the latest reported figures.

The gap between Rajasthan and the rest of the country is substantial. Its installed solar capacity is roughly 11 GW higher than Gujarat's January 2026 figure.

That makes Rajasthan the clearest example of India's large-scale solar expansion.

What does the ranking tell us about solar power in India?

The top 10 states reveal three different patterns.

1. Large solar parks drive the biggest numbers

Rajasthan and Gujarat are far ahead largely because of utility-scale solar.

Large projects can add hundreds of megawatts or even gigawatts of capacity at a time, making them powerful drivers of state-level rankings.

2. Rooftop solar is changing the picture

Maharashtra, Gujarat, Haryana and several other states demonstrate that rooftop systems can become a meaningful portion of total installed capacity.

This matters because rooftop solar is directly connected to consumers. A household or business can use the electricity generated on its own premises, subject to the system configuration and applicable grid rules.

3. Installed capacity is not the same as generation

A state having 10 GW of installed solar does not mean that 10 GW is being produced continuously.

Solar generation changes with:

Time of day
Season
Weather
Panel orientation
Shading
System design
Equipment performance
Grid availability

That is why installed capacity is useful for comparing the scale of solar deployment, but it is not the only measure of performance.

Featured Snippet: Which state has the highest solar power capacity in India?

Rajasthan has the highest installed solar power capacity in India, with about 37.93 GW as of January 2026. Gujarat ranks second at 26.91 GW, followed by Maharashtra at 19.11 GW.

What should homeowners learn from India's solar leaders?

A state-level ranking is useful, but it should not be the deciding factor for a residential solar installation.

The more useful questions are local and practical:

How much electricity does the home consume?
How much usable roof space is available?
Does the roof receive direct sunlight for most of the day?
Are there nearby trees, buildings or water tanks causing shade?
What panel and inverter combination suits the roof?
Is the structure suitable for the proposed installation?
What happens to excess electricity sent to the grid?
What approvals and metering arrangements apply?
What exactly is included in the installation quotation?
When will each stage of the project be completed?

A solar quote should therefore be evaluated as a complete project rather than simply as a price per kilowatt.

Two installers can propose the same system size while offering very different equipment, mounting structures, warranties, wiring specifications, monitoring systems and installation quality.

Solar installation checklist for homeowners

Before approving a rooftop solar project, check:

Expert tips before choosing a solar installer

Don't compare only the final price

A cheaper quote may exclude important work that appears later as an additional charge.

Compare the scope line by line.

Ask for the exact equipment

"Tier-1 panels" or "high-efficiency inverter" is not enough. The quotation should identify the equipment being proposed so that different offers can be compared properly.

Treat installation quality as part of system performance

Solar panels may have a long service life, but the system also depends on mounting, wiring, earthing, protection devices and inverter installation.

A good panel cannot compensate for poor workmanship.

Keep project milestones visible

Solar installation involves several stages. Site assessment, design, procurement, mounting, electrical work, commissioning and documentation should not become one vague promise of "installation completed soon."

Structured project tracking can make it easier for homeowners to see what has actually been completed before the next payment is released. This is one area where TatvaOps approaches solar installation as a managed project rather than simply connecting a homeowner with an installer.

Common mistakes to avoid

Choosing a system size from a neighbour's installation

Electricity consumption varies significantly between households. Your system should be based on your own usage and roof conditions.

Ignoring shading

A small amount of shade can affect the output of a solar array, particularly when panels are connected in configurations where shading affects multiple modules.

Accepting a vague quotation

If equipment, structure, wiring, protection devices and commissioning aren't clearly described, you're comparing incomplete information.

Paying too much before work is verified

Large upfront payments can reduce the homeowner's leverage if work is delayed or does not match the agreed specification.

A milestone-based approach creates a clearer connection between completed work and payment. TatvaOps, for example, uses milestone-based payments where homeowner approval is required before payment is released.

Forgetting future maintenance

Solar panels need relatively little routine maintenance, but cleaning, visual inspection, inverter monitoring and electrical checks still matter. The installation should include a clear understanding of who handles support after commissioning.

Conclusion

India's solar expansion is being driven by a mix of large solar parks, rooftop systems, agricultural applications and distributed installations.

Rajasthan leads the country with 37.93 GW, followed by Gujarat at 26.91 GW and Maharashtra at 19.11 GW. Further down the list, states such as Tamil Nadu, Karnataka, Andhra Pradesh and Madhya Pradesh show how widely solar development has spread across the country.

But the most useful takeaway for a homeowner is not simply which state ranks first. It is that solar has become a serious infrastructure decision, and the quality of the system design and execution can matter as much as the technology itself.

If you're planning a solar panel bangalore project, a structured platform such as TatvaOps can be worth considering as a way to compare verified installers, document the project scope, track execution and connect payments to completed milestones. The goal should be simple: choose the right system, know exactly what you're paying for, and have a clear record of what was delivered.
