Frequently asked questions

What is a Solar Rooftop System?

  • In a solar rooftop system, the solar panels are installed in the roof of any residential, commercial, institutional and industrial buildings. This can be of two types.
  • (i) Solar Rooftop System with storage facility using battery, and
  • (ii) Grid Connected Solar Rooftop System.

 

What does PV stand for in solar power?

  • The photoelectric effect refers to the emission, or ejection, of electrons from the surface of a metal in response to light. It is the basic physical process in which a solar electric or photovoltaic (PV) cell converts sunlight to electricity. Sunlight is made up of photons, or particles of solar energy.

 

What is a Grid Connected Solar Rooftop System?

  • In grid connected rooftop or small SPV system, the DC power generated from SPV panel is converted to AC power using power conditioning unit and is fed to either of 440/230 Volt three/single phase line or to the grid 33 kV/11 kV three phase lines depending on the capacity of the system installed and the regulatory framework specified for respective States. These systems generate power during the day time which is utilized fully by powering captive loads and feed excess power to the grid as long as grid is available. In case, where solar power is not sufficient due to cloud cover etc., the captive loads are served by drawing power from the grid.

 

How does a solar grid tie work?

  • Sunlight falls on the solar array and generates DC electricity. That DC electricity is converted into household 230V / 415V AC electricity by the inverter. The AC electricity is fed into your electric meter and circuit breaker panel. The electricity either goes to your appliances and loads, or to the grid, or some to each.

 

What is Net Metering?

  • Net metering is an arrangement that allows the Solar Power System owner to sell excess solar energy to the utility company or buy deficit energy from the utility company using a meter to track import and export of energy (Units of electricity).

 

What is warranty for Solar Modules & Inverters?

  • Solar Modules are warranted for 10 year Product warranty & 25 year limited output warranty. Solar Inverters are warranted for 5 years. This warranty can be extended with extra premium.

 

What is life of Solar plant?

  • Usually Life of Solar Plant is about 25 years however Solar Panels will be continued to produce the energy thereafter.

 

What are the Government Incentives for RoofTop Solar Project?

  • To promote the RoofTop Solar System, Government is providing subsidy for non-profitable organization like Residence, Trust’s, Hospitals, Educational Institutes & NGO’s. Organization like commercial, Industrial units etc. which have profit / loss account will get cash benefit in terms of Accelerated Depreciation in their business.
