What is Rooftop Solar?

A solar rooftop system typically consists of solar modules, solar inverter(s) and other electrical components such as meter(s), cables etc. Solar Photovoltaic modules and allied electrical equipment are installed on residential and commercial rooftops and connected to the power grid. These are known as Grid- connected Rooftop Photovoltaic systems(GRPV).

When all these components are combined together and placed in open space facing sunlight, the system starts generating electricity proportional to the intensity of sunlight. The electricity, thus generated, can be used directly by the consumer. If consumer is not able to use complete electricity generated by GRPV system, the excess electricity generated can be fed to the utility grid (DISCOM network) and the units get adjusted in the electricity bill. It is important to mention here that 1 kW of solar PV plant can generate more than 1200 units of electricity in a year.

Components of Roof Top Solar

Solar PV Modules

Solar PV Modules are in the form of flat, rectangular panels which convert sunlight directly into electricity. Multiple panels are connected together to form arrays as per the desired capacity of the system.


Solar Inverters convert the DC electricity produced by the PV panels into AC electricity which can then be consumed by appliances within the premises or injected into the DISCOM grid.

Bi-Directional Meter

Measure how much power your premises use and any excess power that the solar system feeds to the grid.
