solar power cheaper than diesel/grid power?

Rooftop solar power is much cheaper than power from diesel generators. Solar PV generates power at a cost of about Rs. 7-8.5/unit while diesel generates power at about Rs. 16/unit. Whether solar is cheaper than grid power depends on your current tariff.

How much does a rooftop solar PV system cost?

A rooftop solar PV system costs approximately Rs. 1,00,000/kWp (Kilowatt peak) including installation charges but without batteries.

What are the permissions required for putting up a rooftop solar PV plant?

Typically, permissions are not required to set up rooftop installations with capacity less than 10 KW. If the capacity exceeds 10 KW, the main approval required is for the developer to get permission from the nearest substation.

I have a manufacturing unit that operates for 9 months a year and is under maintenance for the remaining.

The capacity of the plant will be decided keeping in mind the minimum consumption at any time of the term. Once agreed upon, the billing will be done on the generation of the plant..

If my roof is shaded, does that make a difference?

Shade reduces the amount of electricity your system can produce. The panels operate independently, so if one panel is in shade during part of the day, the others still generate electricity. Our installers will design your system for maximum sun exposure, but sometimes a roof may be too shady to make solar feasible.I am text block. Click edit button to change this text.

  • Some limiting factors are:
  •  Solar power is generated only during the daytime on non-rainy days
  •  Solar power may not handle the heavy starting currents required by    heavy machinery
  •  The output of the solar plant varies as the sun moves across the sky,  and as clouds move across the sun.

How much maintenance is required?
