What is Tata Power Solar Rooftop System?

The Tata Power Solar Rooftop System is a solar energy solution offered by Tata Power Renewable Energy Limited (TPREL). The system involves installing solar panels on the roof of homes, shops, factories, or offices. These panels generate electricity from sunlight, which can be directly used for household consumption or business purposes. Any surplus electricity can be fed back to the grid through a net meter, reducing your electricity bills further.

Tata Power Solar is one of the oldest and most trusted solar companies in India, with more than 30 years of experience in the renewable energy sector.

How Does Tata Power Solar Rooftop System Work?

  1. Solar panels installed on the rooftop absorb sunlight.

  2. The energy is converted into DC (Direct Current) electricity.

  3. An inverter converts DC into AC (Alternating Current) electricity.

  4. Electricity is used to power household or business appliances.

  5. Excess electricity is sent to the grid via a net meter.

  6. The grid provides credit for electricity sent, reducing your monthly electricity bills.
