Solar Calculator Meghalaya 2026
Size a realistic rooftop system for your Meghalaya home under MePDCL net metering and the PM Surya Ghar subsidy, with the state's heavy cloud cover built in.
1 Your electricity
Enter your 6-digit PIN to auto-fill your district's average daily generation from NASA satellite data. You can always edit it below.
Indian residential tariffs typically run ₹6–₹9 per unit and rise every year. Check a recent bill for your exact slab rate.
2 Cost & generation
A complete on-grid setup (panels, inverter, structure, wiring, installation) runs about ₹50,000–₹60,000 per kW in 2026. Tier-1 brands (Tata, Adani, Waaree) cost a little more.
Most of India gets about 4 units (kWh) per kW per day on average; sunnier states (Rajasthan, Gujarat) can reach 4.5–5.
3 Subsidy & state top-up
Central subsidy: ₹30,000/kW up to 2 kW, +₹18,000 for the 3rd kW, capped at ₹78,000 for any system 3 kW and above (residential, up to 10 kW). As of May 2026 (per MNRE). Always confirm current rates at pmsuryaghar.gov.in before applying.
Some states add their own subsidy on top of the central one (e.g. Gujarat has offered ₹10,000/kW). Enter your state's per-kW top-up if any — leave 0 if unsure. Verify with your DISCOM.
4 How you'll pay
Indicative estimates only. Subsidy rules and tariffs change by government notification and vary by state/DISCOM. Assumes a gradual annual tariff rise and panel degradation. Confirm current PM Surya Ghar rates and get installer quotes before purchasing.
How PM Surya Ghar subsidy is calculated
• Up to 2 kW:
₹30,000 per kW (1 kW = ₹30,000; 2 kW = ₹60,000)• 3rd kW:
+₹18,000 (so 3 kW = ₹78,000)• 3 kW and above: capped at
₹78,000 (no extra above 3 kW; residential eligibility up to 10 kW)Net cost =
system cost − central subsidy − state top-up. Annual savings = annual units generated × tariff (capped at your usage). Payback = net cost ÷ annual savings; the free-electricity date is today plus the payback period.

Rooftop solar in Meghalaya: MePDCL, net metering and a cloudy sky
Power in Meghalaya is distributed by the Meghalaya Power Distribution Corporation Limited (MePDCL), the retail arm of the state utility MeECL. If you want to go solar and cut your bill, MePDCL is the office you apply to for a grid connection and a net-metering agreement. There is a single state DISCOM, so there is no confusion about who supplies you.
How net metering works here
Under net metering your panels feed surplus daytime units into the grid, MePDCL records both import and export on a bi-directional meter, and you are billed on the net. Domestic tariffs in Meghalaya are telescopic slabs, roughly 4.5 to 6.5 rupees per unit as consumption rises, so we use about 5.5 rupees per unit as a representative figure. Because self-consumed solar is worth your slab rate while exports are credited at a lower value, matching the array to your daytime use pays off.
- Single DISCOM statewide: MePDCL under MeECL.
- Apply for the net-metering arrangement before you commission the system.
- Representative domestic tariff used here is about 5.5 rupees per unit; your slab may differ.
The rain and cloud reality
Meghalaya is honestly one of the toughest solar states in India. Cherrapunji and Mawsynram are among the wettest, cloudiest places on earth, and the June to September monsoon can blanket the hills for weeks. We use a conservative yield of about 3.5 units per kW per day as an annual average, lower than sunnier states. That is deliberate: judge your system on the full-year figure, not a bright winter morning. A slightly larger array, or a battery to store what you do generate, helps smooth the cloudy spells. Compare options with our on-grid solar calculator and solar savings calculator.
PM Surya Ghar subsidy
The national PM Surya Ghar: Muft Bijli Yojana pays 30,000 rupees per kW for the first 2 kW, adds 18,000 for the third kW, and caps at 78,000 rupees for systems of 3 kW and above (allowed up to 10 kW), paid by direct bank transfer after commissioning, with collateral-free loans near 7 percent. Meghalaya is a North-East special-category state that may qualify for enhanced central assistance, so verify the current amount on pmsuryaghar.gov.in before you sign. Size the array with our system size calculator and store power with the battery bank calculator.
A quick worked example
Take a 3 kW system in Shillong. At about 3.5 units per kW per day it makes roughly 10.5 units daily, near 315 units a month averaged over the year. Offsetting units worth about 5.5 rupees each is near 1,730 rupees of value a month before monsoon dips. After subsidy the net cost still pays back over several years.

Frequently asked questions
MePDCL, the Meghalaya Power Distribution Corporation Limited under MeECL, is the single state DISCOM. You apply to MePDCL for the grid connection and the net-metering agreement before commissioning your rooftop system.
No, but it does lower yield. Meghalaya has some of the cloudiest, wettest weather on earth, so we use a conservative 3.5 units per kW per day. A slightly larger array or a battery helps, and over a full year a well-sized system still saves money.
The national amount is 30,000 per kW up to 2 kW, plus 18,000 for the third kW, capped at 78,000 rupees for 3 kW and above. As a special-category North-East state Meghalaya may get enhanced central assistance, so verify the current figure on pmsuryaghar.gov.in.
Domestic MePDCL rates are telescopic, roughly 4.5 to 6.5 rupees per unit across slabs, so we use about 5.5 rupees per unit as a representative value. Check your own bill, since your effective rate depends on how much you consume each month.
