Estimate From Your Bill

Use this when you know the usual bill but not exact units.
Hybrid includes a battery cost allowance.
Roof condition adjusts expected generation loss.
Higher daytime usage improves savings because it avoids expensive imported units instead of exporting at a lower credit rate.

System package options

Lowest upfront

Budget on-grid

Rs 1,000,000 - Rs 1,160,000

For users who want the lowest practical upfront cost without battery backup.

  • 8kW panels

Rs 1,680,000 - Rs 2,480,000

For users who need backup during outages and can accept a longer payback period.

  • 8kW panels
  • hybrid inverter
  • battery allowance
  • backup wiring and protections
Battery capacity, cycle warranty, and backup load design should be confirmed.
Bijli Hisab separates official references from market estimates. Final bills and installation quotes can vary by provider, site survey, equipment brand, and policy updates.

Flexible assessment

Users can start with bill amount, monthly units, or detailed peak/off-peak units. Bill upload can come later as a convenience, not a requirement.

Solar decision

The result recommends a practical system size and shows generation, cost range, expected savings, and payback in one view.

Trust layer

Source links and estimate confidence are shown openly, so users understand what is official data and what is market estimation.
