These documents are required to verify identity, confirm property ownership, check electricity connection details, and ensure direct subsidy transfer without fraud or duplication. They help make the process transparent, secure, and properly tracked under the government scheme.
9. Exceptions for Tenants
If someone is a tenant, they can still apply under the PM Surya Ghar: Muft Bijli Yojana, but there are a few important conditions and adjustments.
- Permission from the property owner is required
Since rooftop solar panels are installed on the building, the landlord must give written consent. This ensures legal approval for installation on a rented property.
- Property ownership documents are replaced by consent proof
Instead of ownership papers, tenants may need a No Objection Certificate (NOC) or written approval from the house owner.
- Electricity connection must be in the applicant’s or household usage
The solar system is usually linked to the existing electricity meter, so clarity on billing responsibility is important.
Why this matters:
These conditions ensure that the installation is legally valid and that both the tenant and property owner are protected. Since rooftop solar is a long-term setup, government authorities need clear authorization before approving subsidies and installation.
In simple terms, tenants can benefit from the scheme, but landlord approval is the key requirement before moving forward.

The subsidy amount—which can range from ₹30,000 to ₹78,000 depending on the system capacity—is typically transferred directly to your bank account via Direct Benefit Transfer (DBT) within 30 to 45 days of the commissioning certificate being issued.
Solar Panel Installation Under Government Scheme
This is a structured process of converting sunlight into electricity, managing that power through an inverter, and using a net meter to export surplus energy to the grid for credits.
How Rooftop Solar Systems Work
- Solar Panels (Photovoltaic Modules): These panels, typically made of silicon cells, are installed on the roof to absorb sunlight. They generate Direct Current (DC) electricity. To get the most electricity out of the 300 units, we need to be efficient. Using quality panels, like Alpex Nikko Topcon can help generate more power.
- Inverter: The DC electricity generated by the panels is sent to an inverter, which converts it into Alternating Current (AC). This makes the energy suitable for powering household appliances.
- Net Meter (Bi-directional Meter): When your solar system produces more electricity than you consume, the surplus power is exported to the grid. When the system produces less, you draw power from the grid. The net meter tracks this exchange, allowing you to pay only for the net electricity used.
Installation Procedure Under Government Scheme
Register: Apply on the National Rooftop Solar Portal.
Feasibility Check: The DISCOM (power distribution company) checks if the rooftop can support the system.
Installation: Hire an MNRE-registered vendor.
Net Metering & Inspection: The DISCOM installs a net meter and issues a commissioning certificate.
Subsidy Release: Upload installation details and bank account information to receive the subsidy directly
