Tamil Nadu charges rooftop solar owners for using the grid. The TNERC rates, the 20 percent domestic rate, the 50 percent MSME cut, and a worked example of the monthly cost.

The 2019 state solar policy, the TNERC regulations that really govern rooftops, network charges, the 2024 draft rules and the new state top-up, in one place.

The scheme runs until 31 March 2027. What that date means for your application, what the extension reports say, the latest progress, and Tamil Nadu's new top-up.

PM Surya Ghar does not give you 300 free units. It subsidises panels that make them. What you pay, how many units your roof produces in Tamil Nadu, and why the bill is not zero.

How to raise a PM Surya Ghar complaint on the portal or helpline 15555, the 30-day resolution rule, and which problems go to the vendor, the DISCOM or a consumer forum.

The model agreement MNRE publishes for consumer and vendor, read clause by clause. What the vendor must do, what you must do, and what to add before you sign.

The subsidy is only paid through a vendor registered on the National Portal. Where the vendor list is, what registration proves, what it does not, and how to choose.

The scheme's actual eligibility rules from the MNRE guidelines: residential connection, DCR panels, grid connection. Tenants, SC/ST, age limit, second homes and businesses answered.
