Solar Sales Conversion Calculator
The solar sales funnel from lead to installed system, and where the deals actually disappear.
Result
Cancellation after signing is the stage that distinguishes solar from most trades. Contracts fall out on credit decline, failed roof inspection, shading found on survey, utility refusal or simple buyer's remorse during the long wait for permits, and a company that only tracks close rate never sees it.

About this calculator
Why do signed deals fall through?
Credit declines, a roof that turns out to need replacing, shading found at survey, utility interconnection refusal, and the long permitting wait giving customers time to reconsider. Twenty percent fall-out is not unusual.
Which stage should I fix first?
Usually fall-out after signing, because that work is already paid for in sales cost. Qualifying credit and checking the roof before signing removes most of it.
The formula
each rate = that stage / the stage before it
