If you''re installing solar on your rooftop in Maharashtra, net metering is the single most important thing to get right. Get it working, and you save 60-80% on your electricity bill for the next 25 years. Miss a step, and you''ll be exporting expensive electricity to MSEDCL for free while your bill barely budges.
Most homeowners in Mumbai, Pune, Nagpur, Aurangabad, and Nashik get this wrong in the same three or four ways. Here''s how MSEDCL net metering actually works in 2026 and what to watch out for.
The basics — what net metering does
Your solar panels make electricity during the day. Sometimes you use all of it, sometimes you make more than you need. Net metering lets you export the extra to the MSEDCL grid and get credit for it — which offsets the units you draw from the grid at night.
At the end of each billing month, your MSEDCL bill shows the net — units drawn minus units exported. That''s what you pay for. If you generate more than you consume across the month, the extra units carry forward to the next month. At the end of the settlement year (usually March), any leftover surplus is either paid out at MSEDCL''s Average Power Purchase Cost (APPC) — which is much lower than what you pay for consumption — or forfeited depending on your connection type.
The math works because you buy grid power at ₹8-12/unit (varies by slab) and export solar at the same tariff via net metering. It''s a straight one-for-one credit up to your installed capacity.
Who is eligible
Any MSEDCL LT (low tension) consumer can apply for net metering up to 100% of your sanctioned connected load. Residential, commercial, industrial — all covered. Maharashtra''s net metering rules also allow systems up to 500 kW for commercial and industrial consumers with the appropriate connection.
For most Maharashtra homeowners with a 3-5 kW connection, this means you can install up to 3-5 kW of solar and export the surplus. Want more? You''ll need to apply to enhance your sanctioned load first.
The actual application process (2026)
MSEDCL runs the entire process on their online portal now — the days of physical file-pushing are (mostly) gone. Your installer should handle this end-to-end, but knowing the steps helps you check they''re doing it right.
Step 1: Register the project on the MSEDCL solar rooftop portal along with technical specs (panel wattage, inverter capacity, installer details).
Step 2: Once approved, install the system. Your installer submits the completion report and requests inspection.
Step 3: MSEDCL sends a technical inspector to your site. This is the step where delays usually happen. Ideally 15-30 days after your completion request; realistically 45-90 days in busy divisions.
Step 4: After successful inspection, MSEDCL installs the bi-directional (net) meter. Your system is officially "commissioned" and net metering starts from the meter installation date.
Total timeline in 2026: 60-120 days from installation completion to active net metering, depending on your MSEDCL division. Mumbai and Pune divisions are typically faster than rural circles.
What Maharashtra homeowners get wrong
Sizing the system to exceed your consumption. If you install 8 kW when you only use 5 kW worth of electricity monthly, the extra 3 kW worth of generation gets settled at MSEDCL''s APPC rate at year-end — currently around ₹3.5-4/unit versus the ₹8-12/unit you would''ve paid to buy it. You''re essentially giving MSEDCL cheap power. Size your system close to your consumption, not above it.
Assuming the meter starts working from the day panels go up. It doesn''t. Net metering only starts once MSEDCL installs the bi-directional meter, which happens after the inspection. Between panel installation and meter commissioning, your solar generates electricity that offsets consumption in real-time but doesn''t create export credits. Any surplus you generate in that gap is lost.
Not tracking the meter reading properly. Once net metering is active, ask MSEDCL for a meter reading photo on the day of commissioning. This is your baseline. Cross-check it against your monthly bill for the first three months. Errors happen and getting them corrected later is much harder than catching them early.
Skipping the ALMM check. If your panels aren''t on the MNRE ALMM list, you can install and use them, but you can''t claim the PM Surya Ghar subsidy of up to ₹78,000. Every legitimate Indian brand (Waaree, Tata, Adani, Vikram) is ALMM-listed, but some cheap imports aren''t. Verify before you sign.
How much you''ll actually save
Real numbers for a Maharashtra 3 kW residential system in 2026:
- System cost after ₹78,000 PM Surya Ghar subsidy: ₹1.0-1.2 lakh
- Typical monthly generation in Maharashtra: 350-400 units
- Effective grid tariff avoided: ₹8-10/unit (average across slabs)
- Monthly bill saving: ₹2,800-4,000
- Payback period: 30-40 months
After payback, you''re essentially getting free electricity for the next 20+ years. This is the whole reason solar makes financial sense in Maharashtra.
State-specific quirks worth knowing
MSEDCL vs BEST vs TATA Power vs Adani Electricity. If you''re in Mumbai, you might not be an MSEDCL consumer — Mumbai has multiple DISCOMs including BEST, Tata Power, and Adani Electricity. Each has slightly different net metering procedures. Check your electricity bill for the DISCOM name before applying anywhere.
Group net metering for housing societies. Maharashtra allows societies to install shared solar and net-meter the surplus across common area meters. This is the fastest-growing segment for solar in Mumbai and Pune — societies are seeing 40-60% savings on common area bills.
State subsidy stack. Beyond the ₹78,000 PM Surya Ghar central subsidy, Maharashtra offers additional state-level support for residential solar. The exact amount and eligibility changes year to year — verify current rates before applying.
Common questions
How long does MSEDCL take to install the net meter?
Officially 30 days after passing inspection. In practice, 45-90 days is normal in 2026. Mumbai and Pune divisions are faster than rural circles.
Can I install solar without net metering?
Technically yes — you''ll offset your own consumption in real time but can''t bank surplus. Not recommended; you''re leaving 30-40% of your solar''s value on the table.
What if my monthly generation exceeds my consumption?
Excess units carry forward to the next month. At year-end settlement (usually March), any residual surplus is either paid at APPC (much lower than tariff) or forfeited depending on your connection category.
Does MSEDCL charge anything for net metering?
Yes — a one-time application fee (varies ₹500-5,000 depending on system size) and the bi-directional meter cost (typically bundled into your installer''s quote). No ongoing fees for residential.
What to do next
Before you commit to an installer, ask them three questions: (1) how many MSEDCL net metering approvals have you completed in the last year, (2) what''s your typical timeline from installation to net meter commissioning, (3) will you handle the PM Surya Ghar subsidy application end-to-end. Good installers answer these confidently. Bad ones deflect.
Get 2-3 quotes, verify their MSEDCL track record, and choose the one who has done this before in your specific division.
