In brief Central assistance uses national scheme rules, while metering, technical approvals, charges and settlement depend on your state regulator and DISCOM. Check both before installation.

National subsidy, state electricity rules

PM Surya Ghar central financial assistance is a national scheme. Your grid connection still sits under a local DISCOM and State Electricity Regulatory Commission. That is why two people with similar roofs can face different meter processes or export settlement.

A state government can add its own support, but do not assume a social post or old vendor brochure is current. The National Portal should show integrated state support where applicable.

Check these items for your connection

  • Residential consumer category and sanctioned load
  • Maximum system capacity and phase requirements
  • Net metering, net billing or gross metering availability
  • Feasibility, application and meter charges
  • Billing and surplus settlement period
  • Meter procurement and testing responsibility
  • Required protection and inspection documents
  • Any state incentive and its budget or application window

Use this order of sources

  1. Your latest electricity bill for the exact DISCOM and consumer details.
  2. The PM Surya Ghar National Portal for scheme application and registered vendors.
  3. Your DISCOM rooftop solar page for process and forms.
  4. The State Electricity Regulatory Commission for the binding regulation and tariff orders.
  5. MNRE notifications for central scheme rules.

The National Portal’s registration flow asks for state and DISCOM, which helps route the application correctly.

Why we do not publish a fixed 36-state subsidy table

A large table becomes wrong as soon as a budget closes, a tariff order changes or a DISCOM revises a fee. We prefer a reliable checking method to stale precision. Every time-sensitive page on SolarCost.in carries a review date and links to primary sources.

Before paying Save the live portal amount, current order or DISCOM page used for your decision. Ask the vendor to write the assumed subsidy and who bears the difference if eligibility fails.

Common questions

Is the central subsidy different in every state?

The central rate has a standard structure plus higher rates for listed special category states and territories. Separate state support and electricity rules can differ.

Where can I find my DISCOM?

It is printed on your electricity bill. The PM Surya Ghar registration flow also lists participating DISCOMs after you choose a state.
