A solar rooftop system is a combination of many components that convert sunlight into usable electricity.

The components of a rooftop solar include the following –

• Solar panels with PV cells
• Solar inverter
• Solar panel mounting structures
• AC and DC cables
• AC combiner box
• DC combiner box
• Earthing cables
• MC4 connectors

A solar rooftop system works on the concept of conversion of sunlight into electricity. The phenomenon is known as the photovoltaic effect.

When sunlight falls on the PV cells in a solar panel, the sunlight is converted into electricity. The generated power is DC current. An AC combiner box is used to convert that DC power into usable AC power.

The generated AC electricity is fed into a bidirectional metre that supplies power to the house. It also exports excess power to the DISCOM (grid) and imports power from the grid if electricity generated by the rooftop solar system is not enough to cover the daily requirement.

Now that the Direct Benefit Transfer (DBT) has been introduced, the subsidy application process has become much easier. Here’s a step-by-step breakdown:

• Visit the National Portal for Rooftop Solar website.
• Download the Sandes app from the website and install it.
• Register as a customer on the Sandes app.
• Once registered, a discom official will visit your home to assess technical feasibility.
• After receiving the No Objection Certificate (NOC) from the official, choose us as your solar installation company.
• Discuss the project details with us and sign an agreement.
• Upon receiving payment, we will commence the installation process.
• We will then provide a work completion report and apply for a net meter installation on your behalf.
• You will receive a commissioning certificate upon completion.
• Submit your bank account information and upload a copy of a cancelled cheque through the National Portal for Rooftop Solar.
• Once the fund handling agency receives your details, the subsidy will be credited to your bank account within 30 days.
