Solar Cost
How to read your home bill before a solar survey
The three numbers we look at first: units, sanctioned load and consumer category.
Updated 2026-09-03
Monthly units
This is the first input for a capacity range. A single high summer bill should not be treated as the year-round figure.
Sanctioned load
The proposed kW should stay realistic against the connection. We do not design a home system that the connection cannot carry.
Consumer category
PM Surya Ghar is aimed at eligible domestic consumers. If the bill is not domestic, say so early so we do not start a residential subsidy file.
Questions
Is one month of bill enough?
It is a start. A few recent months are better because summer and winter units differ.
