Why Atum

Engineering That Outperforms

Built for India's harshest climates. Engineered to generate revenue while protecting what matters most.

🌪️

Wind Warrior

250 kmph

Engineered to withstand cyclonic wind speeds that destroy conventional solar panels and roofing systems. Certified for India's most severe wind zones.

vs <100 kmph for standard panels
⚡

Power Dense

13W/sqft

Atum generates 13 watts per square foot — 30% more than conventional solar panels at 10W/sqft. Same roof space, significantly higher returns.

30% more generation in same space
🛡️

Zero Micro-Cracks

Never

Atum's monolithic structure eliminates the micro-cracks that plague conventional solar modules over time, maintaining peak performance for 25+ years.

Structurally superior design

Rapid Deploy

1 Step

A single integrated installation vs. the conventional two-step process of laying a roof first, then mounting solar panels on top. Faster, cheaper, cleaner.

vs 2-step conventional install
See The Difference

Metal Roof + Solar ModulesvsAtum Integrated Solar Roof

Two systems bolted together versus one purpose-built roof that generates power from day one.

Galvalume / Metal Roof + Solar Panels

The old way — two separate systems, double the hassle

Solar panels mounted on a standing seam metal roof
TWO SEPARATE SYSTEMS

Panels racked on top of metal roof — gaps & mounting points

Mounting hardware punctures the roof membrane, creating leak points and corrosion risk over time

Solar panels racked on corrugated metal roof
WIND UPLIFT RISK

Raised panels catch wind — uplift failures above 90 kmph

Air gap under racked panels acts like a sail. Cyclones routinely tear off panels — a total loss

Solar panels bolted on metal industrial shed roof
DOUBLE INSTALLATION COST

Pay for the roof. Then pay again for the solar install.

Two separate contractors, two timelines, two warranties. Panels also lose 10–20% power in the gap heat-trap

Key Problems

  • ✗ Mounting hardware creates leak & corrosion points
  • ✗ Panels fly off at winds >90 kmph — no wind uplift rating
  • ✗ Heat trap under panels reduces generation by 10–20%
  • ✗ Double installation: roof contractor + solar contractor
  • ✗ Two separate maintenance contracts, two warranties
  • ✗ Roof is still a sunk cost — panels are an add-on burden

Atum Integrated Solar Roof

One system — roof + power generation, built as one

ONE INTEGRATED SYSTEM

Solar cells embedded in the roof sheet — flush, seamless

No separate racking, no mounting holes. The roof IS the solar panel — zero gaps, zero leak points

Atum solar roof installed at AP CM Camp Office — flush profile withstanding cyclone winds
250 KMPH WIND RATED

Flush profile withstands 250 kmph winds — cyclone proof

No raised panels to catch wind. The aerodynamic profile is structurally engineered to India's highest wind zones

30% MORE POWER

30% more generation — same footprint as a metal roof

No heat-trap air gap. Cells run cooler, perform better. More kWh per sqft than any rack-mounted alternative

Atum Advantages

  • ✓ No mounting hardware — zero leak or corrosion points
  • ✓ 250 kmph wind uplift rating — India's highest wind zones covered
  • ✓ 30% more power per sqft vs racked panels on metal roof
  • ✓ Single installation step — one contractor, faster completion
  • ✓ One warranty covers structure + generation
  • ✓ Roof pays revenue from day one — not a sunk cost
