The short answer
Rooftop solar in Navi Mumbai costs about ₹2.00 lakh to ₹2.50 lakh for 3 kW before subsidy. After the ₹78,000 PM Surya Ghar subsidy, that falls to roughly ₹1.22 lakh to ₹1.72 lakh. Each kW generates 3.8 to 4.2 units a day on this coast. MSEDCL, trading as Mahavitaran, runs net metering here. Payback lands between three and a half and five years.

Most Navi Mumbai solar pages park the price behind a callback form. This table answers it outright. Find your monthly bill in the left column, then read across for system size, monthly units, roof needed, subsidy and payback. The planned-node layout helps you here: rooftops in Navi Mumbai are far more uniform than in an organically grown city, so these bands hold across most terraces.
| Your monthly bill | System | Generates | Roof needed | Cost after subsidy | Payback |
|---|---|---|---|---|---|
| Up to ₹1,800 | 2 kW 1–2 BHK, one AC used sparingly | 225–250units/month | ~200 sq ft | ₹80,000 – ₹1.15 lakh ₹1.40 lakh–₹1.75 lakh before ₹60,000 subsidy | 3.5–4.5 years |
| ₹2,000–₹3,500 | 3 kW Best value The largest system that still earns the full ₹78,000 | 340–375units/month | ~300 sq ft | ₹1.22 lakh – ₹1.72 lakh ₹2.00 lakh–₹2.50 lakh before ₹78,000 subsidy | 3.5–4.5 years |
| ₹3,500–₹6,000 | 5 kW 3 BHK running two ACs through summer | 565–625units/month | ~500 sq ft | ₹2.32 lakh – ₹3.02 lakh ₹3.10 lakh–₹3.80 lakh before ₹78,000 subsidy | 4–5 years |
| ₹6,000–₹13,000 | 10 kW Bungalows, clinics, shops, coaching institutes | 1,130–1,250units/month | 700–1,000 sq ft | ₹4.87 lakh – ₹6.12 lakh ₹5.65 lakh–₹6.90 lakh before ₹78,000 subsidy | 4–5 years |
| Above ₹13,000 | 25 kW+ Commercial connections, on accelerated depreciation | 2,825–3,125units/month | Site-specific | ₹11.50 lakh – ₹14.50 lakh ₹11.50 lakh–₹14.50 lakh, no subsidy | 3–4.5 years |
Indicative Navi Mumbai market ranges for 2026, covering Tier-1 modules, a branded inverter, galvanised structure, protection and installation. These are not a Heaven Green quotation. Subsidy amounts are the central PM Surya Ghar figures published on pmsuryaghar.gov.in. Generation assumes a shadow-free, roughly south-facing roof.
The 3 kW cliff decides most Navi Mumbai orders. PM Surya Ghar pays ₹30,000 per kW for the first two kilowatts and ₹18,000 for the third, then nothing. So the subsidy covers around a third of a 3 kW system but barely a tenth of a 10 kW one. If your bill sits on the boundary, 3 kW returns more rupees per rupee spent. A vendor pushing you straight to 5 kW should explain why in units, not in adjectives.
A cheap quote here is cheap in the structure. Galvanising thickness, cable gauge, earthing and surge protection separate the bottom of each band from the top. On a coastal roof they also decide whether the mounting system is still sound in year ten. Ask for a written Bill of Materials listing make, model and quantity.
The Navi Mumbai-specific warning: society permission comes before the quote. Most of this city lives in registered co-operative housing societies, and the terrace is common property. Get a managing committee resolution and a clear allocation of terrace space in writing first. Deposits paid before that resolution exists are the commonest way a Navi Mumbai solar order stalls for months.
You will notice the table shows units, not a rupee saving. The rupee figure depends on the tariff slab you personally land in, which is printed on your own MSEDCL bill and moves with consumption. We are not going to guess it. Bring your last bill to the free survey and we will work the exact number out with you, in front of you. No guesswork, and no number you cannot check against your own bill. Prefer to work it out yourself first? Put your bill into our solar savings calculator. No phone number required.

PM Surya Ghar Muft Bijli Yojana
Maximum central subsidy for a residential rooftop system.
There is no separate Navi Mumbai subsidy, and any vendor advertising one is describing something that does not exist. PM Surya Ghar is a central scheme, so the amount is identical nationwide. What changes by city is which licensee processes the file, and here that is MSEDCL.
You register at pmsuryaghar.gov.in using your MSEDCL consumer number, mobile, Aadhaar and address. We sit with you for this. A consumer number that does not match Mahavitaran's records is the single commonest reason a file stalls before it starts.
MSEDCL checks the application against your sanctioned load and the loading on your distribution transformer. You then select an empanelled vendor. Heaven Green Energy is empanelled, so we map straight onto your application.
We supply Adani modules with traceable serial numbers and hand you a Bill of Materials and warranty schedule. In a society, this is also when the terrace layout and cable route get signed off by the committee.
MSEDCL inspects the installation and fits the bidirectional meter, which generates the commissioning certificate on the portal. Our engineer attends the inspection so queries are answered on the spot.
We file the claim once the certificate issues, and the government credits the subsidy directly to your bank account. It never passes through us. Treat any vendor who offers to collect the subsidy on your behalf as a warning sign.
PM Surya Ghar covers residential consumers only. A shop in Vashi, a unit in Pawane or a warehouse off the Thane-Belapur road cannot claim it. Businesses claim accelerated depreciation on the asset instead, which for a taxpaying company often returns more than the residential subsidy would have paid. Ask your accountant before assuming the residential route was better.
Net metering is where competing Navi Mumbai pages get it wrong, and the mistake costs you every export credit you were counting on. Get the licensee right and the rest of the process is routine.
Navi Mumbai is supplied by Maharashtra State Electricity Distribution Company Limited (MSEDCL), which trades as Mahavitaran. This matters more here than almost anywhere in India, because the city across the creek is not on MSEDCL at all. Mumbai city is split between Adani Electricity, Tata Power and BEST, each with its own licence area, portal, forms and timelines. A page that tells a Vashi or Kharghar reader to apply to Adani Electricity has sent them to a utility that does not supply their meter.
The commercial terms come from the Maharashtra Electricity Regulatory Commission (MERC), not from the discom and not from us. Under the MERC Grid Interactive Rooftop Renewable Energy Generating Systems Regulations, 2019, your system capacity is capped. It must not exceed the sanctioned load in kW or the contract demand in kVA of the premises. Every consumer category may apply, residential, commercial and industrial alike. Consumers may choose net metering or net billing. The licensee assesses applications against the spare capacity on your distribution transformer. Where a file is deficient, the licensee must give you notice and a window to correct it rather than rejecting it outright.
Practically, that means your home or society draws solar first by day and exports the surplus to MSEDCL as credit. That credit offsets what you draw at night and through the monsoon dip.
Consumer details, sanctioned load, system rating, single-line diagram and equipment datasheets go to MSEDCL. For a society, the connection details of the common-area meter go in too.
Filed by usMahavitaran tests whether your sanctioned load and distribution transformer carry the proposed capacity. Oversized systems fail here, which is why we size against sanctioned load on the first visit.
MSEDCLWe install. MSEDCL then inspects earthing, protection, isolation and metering compliance before anything is energised against the grid.
Us, then MSEDCLYour existing meter is replaced with a bidirectional net meter and the commissioning certificate issues. Export credits begin from this date, not from the day the panels went up.
MSEDCL
Running a unit, a warehouse or a society rather than a single flat? The arithmetic is different, and this page is written for homeowners.
Navi Mumbai's commercial rooftop is unusually good stock. The TTC industrial belt runs from Digha and Airoli through Rabale, Ghansoli, Mahape, Pawane and Turbhe down towards Nerul, and it is full of large, flat, structurally sound sheds. Add the Taloja MIDC estate, the warehousing and container yards feeding Jawaharlal Nehru Port, and the office and data-centre campuses around Airoli, Mahape and Vashi. The result is a lot of unshaded square metres sitting above high daytime load. Daytime load is the point: solar is worth most where consumption happens while the sun is up. That describes a factory shift or an office far better than a bedroom.
None of these consumers get PM Surya Ghar. They claim accelerated depreciation instead, and they can avoid capital outlay altogether through OPEX or RESCO structures. We deliver turnkey commercial and industrial EPC across the belt, with structural design to wind-load standards, MSEDCL registration and long-term O&M.
We have built solar since 2017 and delivered more than 10,000 installations across India, from single rooftops to industrial systems in the hundreds of kilowatts. That includes society terraces, standalone bungalows and industrial sheds.
Heaven Green Energy is headquartered at Mota Varachha, Surat. We have no branch in Navi Mumbai. We serve the city and the wider Konkan region through our channel partner network and field engineering team. They run the surveys, supervise installation and handle MSEDCL coordination on the ground. We would rather you knew that before you sign than after. Distance does not change who is responsible when something needs fixing.
Four steps to a spinning net meter, including the parts that belong to MSEDCL rather than to us. We name which steps are ours and which are the discom's.
We measure shadow-free terrace area, check the slab and parapet, read your sanctioned load and twelve months of MSEDCL units, and log shading from tanks, lift rooms and neighbouring towers.
Day 1–2System size, layout, Bill of Materials with makes and models, generation estimated at Navi Mumbai irradiance, your subsidy and your payback. No obligation attached.
Day 3–5We file with the national portal and with MSEDCL, then install once feasibility clears. A typical residential roof takes two to four days of work.
Day 5–15Mahavitaran inspects and fits the bidirectional meter, the commissioning certificate issues, and we file your claim. The government pays the subsidy into your account.
Set by MSEDCLA system specified for an inland plateau roof is the wrong system for the Thane Creek shoreline. Two conditions here change the engineering outright, and a third changes how you read the generation figures. Specify for the coast and the system lasts its twenty-five years.
Navi Mumbai sits on a creek with mangrove flats on three sides and humidity that peaks near 86% in July. Salt-laden air attacks fasteners, clamps, earthing conductors and any exposed cut edge on the mounting structure. This is where coastal installations quietly fail. Insist on hot-dip galvanised or aluminium structure, stainless fasteners of a named grade, and sealed enclosures. It is not an upgrade here, it is the baseline.
The planning authority puts average annual rainfall across Navi Mumbai at 2,500 to 3,000 mm, with roughly 80% of it between June and October. That is why the generation figures on this page sit below Gujarat and Malwa numbers: the annual average already carries a deep July and August dip. It also means waterproofing detail at every roof penetration, proper cable gland sealing and drainage clearance under the array matter more than they do inland.
Pre-monsoon days push past 34°C, and module output falls as cell temperature climbs. A structure therefore needs real clearance under the panels for airflow, not a flush bolt-down that saves steel. Coastal wind loading demands honest foundation design, particularly on the high-rise terraces common in Kharghar and Seawoods. One thing does work in your favour: monsoon rain keeps the glass cleaner here than a dry-season inland roof ever stays.
We install across all eight NMMC wards, the CIDCO nodes on the Raigad side and the TTC industrial belt. An area missing from this list is not an area we refuse, so call and ask.
