Madurai · Tamil Nadu
Independent advice for domestic connections in Madurai. Strong sun and AC-heavy summers help the economics — if your roof is shade-free and the CFA path is clean.

Madurai’s heat drives high daytime and evening loads. A well-sized plant after PM Surya Ghar CFA can cut the painful slab months — but monsoon and neighbour shade still matter. Use the free home check.
Domestic supply is under TANGEDCO. File on the national portal with Tamil Nadu + TANGEDCO. State context: Tamil Nadu rooftop solar. Also see Chennai and Coimbatore.
Common residential CFA up to ₹78,000 for eligible 3 kW+. Apply walkthrough: how to apply.
TANGEDCO has long provided domestic consumers a block of free units, and Tamil Nadu bills are issued on a bi-monthly cycle. Both facts matter before you shortlist equipment.
The free block means low-consumption households have relatively little paid consumption for solar to displace, which lengthens payback no matter how good the plant is. The bi-monthly cycle means people routinely misread their own usage: a bill covering two months looks alarming compared with a monthly figure, and sizing from that misreading leads straight to an oversized system.
Before anything else, convert your bill to a genuine monthly average across a full year, after any free-unit benefit. That number, not the sunshine and not the bill shock, decides whether this is worth doing. Our bill-band guides show the thresholds: ₹1,500 · ₹3,000.
Madurai's heat drives exactly the daytime cooling load that rooftop solar offsets well — air conditioning and fans running while the sun is up is the ideal consumption profile, because self-consumed units are worth full retail value to you.
The same heat works against the panels. Module efficiency falls as cell temperature rises, so summer afternoon output sits below nameplate. This is normal physics rather than a defect, but it means annual estimates should be built from realistic derated figures, and mounting should leave proper air gap beneath the modules.
Evening loads are the flip side. Consumption after sunset is not offset by a standard grid-tied plant at all; it is billed normally or netted against exported credit depending on your metering. Anyone promising that solar will erase a bill driven mainly by night-time usage is overselling — see net metering.
Older parts of Madurai have dense streets and mixed roof heights, so shade from a neighbouring building or stairwell block often matters more than latitude. Terraces here also carry real competing uses — water tanks, drying space, occasional sleeping space in hot months — so decide how much roof you are genuinely willing to give up before a vendor plans the layout for you.
Take your service connection number, tariff category, sanctioned load and a full year of units from the bill. Exceeding sanctioned load can trigger an enhancement with its own charge outside central CFA. Central CFA is commonly up to ₹78,000 for eligible 3 kW+ residential plants and is credited by DBT after commissioning — verify current terms on pmsuryaghar.gov.in, and treat any advertised state extra as something to check live per state top-ups.

Not directly. Consumption after sunset is not offset by a standard grid-tied plant at all; it is billed normally or netted against exported credit depending on your metering arrangement. Anyone promising that solar will erase a bill driven mainly by night-time usage is overselling.
