A Roof That Generates Power For You!

ATUM - The Smartest Roof in India.

The only Electric Roof in INDIA. A roof built with innovative technology that benefits your pocket and the environment.

What is a Traditional or Conventional Solar set up?

  • Conventional standard solar modules take about 100 Sq. ft for 1 kW (Very little optimization because of walkways)
  • GI shed replacement happens every 10 years due to corrosion over time (Not a leak proof solution)
  • Prone to damage during high wind speeds; Not a fire-resistant solution

How is ATUM different?

In simple terms ATUM is ROOF + SOLAR integrated in a single product with very important attributes that are not available in traditional solar panels such as

  • Protection from Fire

ATUM is Fire Resistant

  • Protection from Wind

ATUM can withstand wind speeds upto 200 kmph

  • Protection from Rain

ATUM is a leak proof application

  • Protection from Weather

ATUM has a life of 45-50 years

  • More Power in same space


ATUM offers min. 20% more installed capacity

How does ATUM give 40% more?

Solar cells are integrated in a fiber cement board. You can walk over the panels without causing internal cracks.

Standard Design for conventional

Edge clearance of 1 meter from each side & with walkway
No of modules – 460 Nos (ref)

Optimized Design for conventional

Edge clearance of 1 meter from each side & without walkway
No of modules – 500 Nos (8.70%)

ATUM Design

(No walkway & no edge clearance)
No of modules – 648 Nos (40%)

  • Conventional standard design is to keep 1 meter clearance from all the edges and walkways after suitable intervals, which reduces plant capacity, but ATUM since it is edge to edge gives you up to 40% more capacity.
  • Conventional 1kWp SPV needs 100 sq.ft area where as ATUM needs 66.5 Sq.ft only.
  • Leak proof roof for lifetime of 45-50 years, where GI shed need replacement typically after ~10 years.
