Commercial Solar Rooftop System

Commercial rooftop solar projects offer an excellent financial return in most markets.

One reason is that when solar modules are rooftop mounted, they use the building structure and electrical system to minimize additional materials that would normally be required for ground mount and carport solar facilities. Net metered rooftop projects therefore bring a desirable financial benefit that outweighs most challenges.

For commercial/industrial use, a solar power system is a renewable energy system which uses PV modules to convert sunlight into electricity. The electricity generated can be stored or used directly, fed back into the grid line or combined with one or more other electricity generators or other renewable energy source. Solar PV systems are a very reliable and clean source of electricity that can suit a wide range of applications.


Installation Requirements

There are quite a few factors which decide the feasibility of installing Rooftop Solar Modules. These include

  • For Commercial Rooftop PV Module Installation, the dimensions and overall structure of the roof is crucial.
  • Empty space in the southward direction so that the Solar Modules can absorb maximum solar energy
  • A minimum of 100 square feet area for installation of 1KW solar power output
  • For grid-interactive Solar Rooftop Systems, only a standard bi-directional meter, as approved by MNRE /TSSPDCL / DISCOM, should be installed.
  • The consumer shall have 1 phase / 3 phase supply service connection.
  • A single bi-directional meter shall be installed for export and import of power

How it Works

Rooftop solar system mechanism is based on harnessing sun’s energy to generate electricity.

  • For this, the Solar Modules – which are made up of several photovoltaic cells – are arranged on the rooftop space in a manner to be exposed to maximum sunlight.
  • These solar PV systems capture and absorb the sun’s energy leading to a chemical reaction within the circuit of solar cells and ultimately turning the energy into direct electric current (DC).
  • The DC power produced by the Solar Modules is converted to alternating current (AC) with the help of an inverter attached to the panels. The AC power is then used by the commercial unit for powering the appliances.
  • A Bi-Directional Net-Meter measures energy used and excess energy produced
