What the growth, the rooftop boom and the 500 GW goal mean for a business planning solar. url: https://arraysingenieria.com/india-solar-capacity-2026/ last_updated: 2026-10-11 source: Arrays Ingenieria (Arrays Ingenieria Pvt. Ltd.) --- Guide · Market Update # India's Solar Capacity in 2026: 171 GW and What It Means for Your Business MNRE data put India's solar fleet at 171.05 GW on 30 September 2026. Where the growth is, why rooftop and C&I solar are surging, and how to plan a plant in a crowded market. On this page - The numbers in one place - Why India is building so fast - Where the growth is coming from - What this means if you are planning a plant - How Arrays Ingenieria fits in - Frequently asked questions - Sources By the [Arrays Ingenieria engineering team](https://arraysingenieria.com/about/) · Updated 11 Oct 2026 · 4 min read **Key takeaways** - India had **171.05 GW** of solar on 30 September 2026, per MNRE's physical-progress data - That is about 30 GW more than the 140.6 GW MNRE reported for January 2026 - Grid-connected rooftop solar has reached 33.41 GW; ground-mounted plants make up 125.65 GW - Renewables including large hydro total about 299 GW (about 247 GW excluding large hydro), on the road to 500 GW of non-fossil capacity by 2030 - The scarce resource is now skilled installation and commissioning: book your EPC partner and approvals early ## The numbers in one place India's solar build-out keeps setting records. The Ministry of New and Renewable Energy (MNRE) publishes cumulative installed capacity every month, and its table for **30 September 2026** shows **171.05 GW** of solar. That is up from 150.26 GW on 31 March 2026 and 164.59 GW on 31 July 2026, and roughly 30 GW more than the 140.6 GW MNRE reported for January 2026. **171.05 GW**Solar installed, 30 Sep 2026 **125.65 GW**Ground-mounted plants **33.41 GW**Grid-connected rooftop **~299 GW**Renewable capacity incl. large hydro (MNRE) India's solar capacity by segment, cumulative as on 30 September 2026 (MNRE) | Segment | Installed capacity | What it covers | | --- | --- | --- | | Ground-mounted solar | 125.65 GW | Utility-scale parks and open-access or captive plants on land | | Grid-connected rooftop | 33.41 GW | Homes, factories, warehouses, institutions and commercial buildings | | Hybrid projects (solar part) | 5.36 GW | Solar in wind-solar hybrid projects | | Off-grid solar | 6.63 GW | Solar pumps, mini-grids and standalone systems | | Total solar | 171.05 GW | All of the above | Two trends stand out. Rooftop solar, long the laggard, has accelerated sharply thanks to PM Surya Ghar for homes and to factories and commercial buildings cutting their power bills. And ground-mounted plants keep growing through utility tenders and through companies building captive and open-access plants for their own use. ## Why India is building so fast The direction is set at the highest level. At COP26 in Glasgow in 2021 the Prime Minister announced the **Panchamrit** commitments, the first of which is **500 GW of non-fossil electricity capacity by 2030**. Non-fossil sources passed half of India's installed power capacity in June 2025, five years ahead of the original goal. Policy then makes solar cheaper and easier to adopt: - **GST on solar equipment fell from 12% to 5%** from 22 September 2025, lowering the upfront cost of every plant (see [our GST guide](https://arraysingenieria.com/gst-on-solar-india/)). - **Accelerated depreciation** lets a business that owns its plant write off the cost quickly (see [depreciation explained](https://arraysingenieria.com/accelerated-depreciation-solar/)). - **PM Surya Ghar** subsidises rooftop solar for homes and **PM-KUSUM** solarises farms and feeders. - **Green Energy Open Access** rules let consumers with as little as 100 kW of load buy green power from plants elsewhere. - **ALMM** and import duties steer buyers towards Indian-made modules and, since 1 June 2026, Indian-made cells. For a business the economics are now simple: a well-built plant on your own roof or land produces power for 25 years at a cost per unit well below most commercial and industrial grid tariffs, and the cost of the plant is recovered in a few years. ## Where the growth is coming from ### Utility-scale parks and tenders Large solar parks, such as the 300 MW SECI project at Koppal in Karnataka where Arrays Ingenieria has done pile foundations and DC installation, still account for most new megawatts. New tenders increasingly ask for co-located battery storage (see [storage with solar](https://arraysingenieria.com/battery-storage-with-solar/)). ### Commercial and industrial (C&I) rooftops Factories with large sheet roofs are among the best sites in the country: the roof already exists, consumption is during the day and tariffs are high. Our rooftop work runs from small commercial roofs to multi-megawatt industrial sheds, at smelters, steel and textile plants, consumer-goods units and retail warehouses. The 1980.3 kWp sheet-roof plant at Super Smelters, Jamuria, West Bengal, installed and commissioned by Arrays Ingenieria with Tata Power Solar. ### Tea estates and agro-industry Assam's tea gardens have become a solar story of their own: estates with steady daytime factory load, diesel-generator back-up and spare land are building ground-mount plants. The Chief Minister of Assam inaugurated our 595 kWp plant at Koomber Tea Estate on 1 October 2026 (see [solar for Assam's tea estates](https://arraysingenieria.com/solar-for-assam-tea-estates-guide/)). ## What this means if you are planning a plant Record volumes are good news for prices and choice, but they create bottlenecks in three places: - **Skilled installation crews.** Experienced installation & commissioning teams, piling rigs and supervisors are booked months ahead in the peak season. - **Approvals.** DISCOM feasibility, net-metering or open-access approval and the Electrical Inspector's (CEIG) inspection all take time, and queues grow when everyone builds at once. - **Compliant equipment.** ALMM-listed modules (with List-II cells for covered projects) and BIS-certified inverters must be specified and documented from the start. The practical answer is to start early and choose a partner who has done the work before, at scale and with documents to show for it. Ask for case studies, client certificates and references; our checklist of [12 questions to ask a solar EPC](https://arraysingenieria.com/choose-solar-epc-partner/) is a good place to start.

MNRE's physical-progress data show 171.05 GW of solar installed as on 30 September 2026: 125.65 GW ground-mounted, 33.41 GW grid-connected rooftop, 5.36 GW in hybrid projects and 6.63 GW off-grid. What is India's renewable energy target for 2030? 500 GW of non-fossil fuel electricity capacity by 2030, the first of the Panchamrit commitments the Prime Minister announced at COP26 in 2021. Is it a good time for a business to install solar? For most commercial and industrial consumers, yes: GST on solar equipment is 5%, a business owner can claim accelerated depreciation, and a well-built plant generates for 25 years at a cost per unit below typical C&I tariffs. Book installation crews and approvals early because demand is high. Where can I check the latest official solar figures? MNRE publishes cumulative installed capacity every month on its physical-progress page (mnre.gov.in). PIB press releases summarise the milestones. ## Sources - [MNRE: Physical progress, cumulative as on 30 September 2026](https://mnre.gov.in/en/physical-progress/) - [MNRE on X: solar capacity 140.6 GW as of January 2026](https://x.com/mnreindia/status/2024823382630687102) - [PIB: India ranks third globally in renewable energy installed capacity](https://www.pib.gov.in/PressReleasePage.aspx?PRID=2250039) - [SolarQuarter, 12 Aug 2026, citing MNRE data](https://solarquarter.com/2026/08/12/indias-solar-capacity-surpasses-164-gw-as-2026-installations-approach-29-gw-by-july-end/) - [PIB: PM's national statement at COP26, 1 Nov 2021](https://pib.gov.in/PressReleasePage.aspx?PRID=1768712) This guide explains public policy in plain language for planning purposes.
