The hidden problem

Three causes. One bill that can't tell them apart.

The vendor's easy answer is always "it's just the pollution." But each cause leaves its own signature in the gap between what the roof should make and what it does.

Smog

Nobody's problem

Expected and actual fall together, and recover together.

No action needed

Dust

The vendor's problem

The gap widens every dry day; rain resets it.

Free cleaning, owed for 5 years

Fault

The vendor's problem

Output collapses overnight while sunlight doesn't.

Free repair, owed for 5 years
How it works

From a reading on a roof to a fixed panel

See the full walkthrough →
  1. 1

    Collect

    Yesterday's reading arrives on its own: a DISCOM data logger, the inverter's cloud or a camera clip.

  2. 2

    Compare

    Against what that exact roof should have made, from satellite sunlight and haze.

  3. 3

    Diagnose

    Smog, dust or a fault, told apart by signature. Smog never triggers a complaint.

  4. 4

    Act and verify

    Claim filed with evidence, deadline chased, DISCOM steps in if missed, fix checked from new readings.
