Solar Inverter Market in India 2026, Industry Report

India’s solar inverter market is easy to describe and hard to measure. Every grid-connected system needs an inverter, and capacity additions are well documented. What is not well documented is the market in rupees or in brand shares, where published numbers differ by a factor of two or more. This report keeps to figures that name a source and a date. Where a number cannot be sourced, it says so instead of filling the gap. Data points were checked between 12 and 14 October 2026.

How big is the solar inverter market in India?

Three research firms publish a headline figure, and no two agree. The differences come from scope (solar PV inverters only, or all inverters), base year, currency conversion and how utility-scale central inverters are counted.

The highest 2025 figure is more than twice the lowest. None of the three is a measured sales total. They are modelled estimates behind a paywall, and each firm’s methodology is its own. The practical reading is a range of roughly USD 0.4 to 0.9 billion for 2025, with growth forecasts between about 8% and 14% a year depending on the firm.

A single figure such as “USD 1.4 to 1.6 billion” with 15 to 18% growth is sometimes quoted online. We could not trace it to any of the research firms above or to a trade publication, so this page does not use it.

A better yardstick: capacity added and inverters shipped

Revenue estimates differ, but capacity additions are tracked monthly by MNRE and by analysts such as JMK Research. Inverter demand follows the AC capacity of new plants, so these numbers show how much work the market is actually doing.

Mercom India tracks the inverter side directly. It reported that inverter shipments to solar projects in India increased 40.8% in 2025 compared with 2024, driven by record installations and a strong pipeline for commissioning in the first half of 2026, and that central inverters accounted for 51% of total shipments. Mercom’s 2024 leaderboard coverage put string inverters at 51.3% and central inverters at 48.7%, so the mix swung back towards central units in 2025 as large ground-mount plants came online.

Two cautions apply. First, those are shares of shipments to solar projects, a measure that is weighted towards utility-scale plants where central inverters are common. It is not a residential split. Second, rooftop figures differ by source and cut-off date: MNRE data compiled by Climate Compatible Futures showed 25.7 GW of cumulative rooftop capacity at March 2026, while JMK’s September 2026 figure is 33.4 GW, a different date and a different compilation.

Segment definitions: residential, C&I and utility

The three segments buy different products for different reasons, which is why a single national “market share” is of limited use to a buyer.

The two market reports that publish segment shares disagree, which is itself informative. TechSci estimated for 2025 that string inverters held about 43% of the market, on-grid systems about 72%, three-phase models about 67% and utilities about 51%. Market Research Future estimated string inverters at 45.6%, three-phase at 71.8% and utility-scale at 65.4%. Both agree on the direction: three-phase and on-grid products dominate, because utility and commercial plants dominate revenue. Residential is the fastest-growing application in Market Research Future’s forecast, at 16.0% a year from 2026 to 2035.

For a household, the relevant point is that the inverter is usually chosen by the installer. The procurement checks that matter to you are covered in the on-grid inverter and hybrid inverter hubs.

PM Surya Ghar and the residential pipeline

PM Surya Ghar Muft Bijli Yojana is the main driver of residential rooftop demand. Reports in October 2026 describe a scheme with an outlay of INR 750 billion, a target of 10 million households and a 30 GW rooftop target, with the current scheme ending on 31 March 2027 (TaiyangNews, 12 October 2026, citing Mint). The scheme’s own portal is pmsuryaghar.gov.in, and the household subsidy slabs are in our PM Surya Ghar subsidy amount guide.

Progress figures depend on who is counting and when:

The gap between 17.6 GW and 14.8 GW is a dating and definition difference, not a contradiction. A Business Standard report on 7 October 2026, citing JMK, said the scheme had crossed 17.5 GW while monthly rooftop additions fell for a second month. That matters for planning: the pipeline is large, but it is not accelerating every month.

Within the scheme, state leadership has moved. JMK’s September 2026 update showed Uttar Pradesh adding 234.46 MW of PM Surya Ghar capacity in the month, ahead of Maharashtra (208.04 MW) and Gujarat (165.6 MW). The vendor and eligibility rules sit in our empanelled vendor guide and the complete scheme guide.

Top states by rooftop solar capacity

Rooftop solar is concentrated. MNRE data compiled by Climate Compatible Futures and reported by Down To Earth on 23 June 2026 put national rooftop capacity at 25.7 GW as of March 2026 and showed these states:

The article reports that the top ten states account for close to 86% of the national total. Gujarat and Maharashtra together hold 12,324 MW, about 48% of the 25.7 GW. The table lists the states the article names, and the source does not give Tamil Nadu or Karnataka, so it is not a complete top-ten list.

Stock and growth tell different stories. JMK reported that in FY2026 Maharashtra added the most rooftop capacity at 2,144 MW (25% of additions), followed by Gujarat at 1,777 MW (20%) and Tamil Nadu at 600 MW (7%). In August 2026 Gujarat added 628.7 MW, Uttar Pradesh 489.7 MW and Andhra Pradesh 210.8 MW. Uttar Pradesh, with only 715 MW in March, is the state to watch.

Who supplies the inverters: what is public, and what is not

The only public, repeatable supplier ranking we found is Mercom India’s leaderboard of inverter shipments to solar projects. Mercom named the same five suppliers at the top in recent years, with the order changing:

Read this table for what it is. Share estimates in blog posts are not a substitute for shipment data.

Two developments are worth knowing. TaiyangNews reported on 12 October 2026 that Waaree’s planned inverter manufacturing capacity is 4.15 GW a year, and that India is considering local-content rules for inverters. The market for Indian-made inverters is therefore a policy question as well as a commercial one. Qbits Energy is one Indian inverter maker among others in this market, with on-grid and hybrid lines.

Five checks that matter for the Indian grid and climate

A brand that does well in Europe or China still has to cope with Indian grid conditions, heat and service distances. These are the checks procurement teams actually use. They are a checklist, not a score.

ALMM and inverter compliance are separate checks

MNRE’s ALMM covers solar modules (List-I) and cells (List-II). MNRE publishes no inverter list. List-II was notified to be effective from 1 June 2026, so a module on List-I must use cells from a List-II manufacturer (Energetica India, 10 December 2024). MNRE has since issued clarifications and exemptions for some project types, so check the current position on MNRE’s site.

For inverter buyers this means two parallel checks: the module and cell requirement against the ALMM lists, and the inverter against its own certificates and the DISCOM’s accepted-make list. A seller who answers an inverter question with an ALMM claim is answering the wrong question. Our ALMM scope guide walks through the difference.

The direction of policy is worth watching. TaiyangNews reported on 12 October 2026 that the Renewable Energy Secretary said proposals for locally made inverters and batteries in the next phase of PM Surya Ghar remain under consideration. Nothing has been notified.

Trends: hybrid systems, storage and monitoring

Hybrid inverters, battery storage and remote monitoring all feature in installer conversations, but only some of it can be quantified from public sources.

Hybrid and storage. No public series tracks hybrid inverter shipments in India. The constraint on storage is supply: TaiyangNews, citing Wood Mackenzie, reported domestic battery-cell capacity of about 2 GWh in 2026 against a tender pipeline of roughly 260 GWh. A hybrid inverter without a locally available battery is a partial system, so the battery decision matters as much as the inverter. Our on-grid versus hybrid ROI analysis compares costs under different outage patterns.

Monitoring. Remote monitoring is moving from an extra to an expected feature, because installers servicing many sites cannot visit each one. The useful test is whether the system tells the installer what is wrong, not only that something is.

EV charging. Some commercial and society projects combine rooftop solar with EV charging. We found no sourced India share for this, so we make no estimate. It is a design consideration for inverter sizing and export control.

Challenges that limit growth

The DISCOM processes remain the hardest constraint to solve at project level, because they depend on grid infrastructure and administration rather than the installer. Where a feeder cannot take exports, a net metering alternative or an export-limited design is a conversation with the DISCOM, not a decision for the inverter vendor.

Where to track these numbers yourself

Market figures go stale within a quarter. If you rely on them for a purchase, a tender or a plan, go to the publishers directly and check the date on each figure before you use it.

Three habits make any of these figures safer to use. Write down the publisher and the date next to the number when you copy it. Compare like with like, so a shipment share is never set beside a revenue share. And treat any single market-size figure with no named source, however confident it sounds, as an unverified claim rather than a statistic.

What the data means for buyers and installers

• Do not anchor on a market-size number. The estimates differ by a factor of more than two, and none is measured sales.
• Use shipment and capacity data for direction, not for brand choice. Mercom’s ranking is weighted to large plants. A home buyer should compare exact models.
• Treat rooftop concentration as a service question. If your state is outside the main rooftop states, ask harder questions about local service.
• Separate the module check from the inverter check. ALMM answers the first. Certificates and DISCOM acceptance answer the second.
• Expect rules to move. The local-content proposal for inverters is under consideration, not law.

Qbits Energy publishes datasheets for its on-grid and hybrid models on the datasheet page. For warranty and service terms, obtain the current written terms for the exact model and sale, since the public datasheets do not set a universal duration, remedy or service commitment.
