The solar routing problem is really five problems
Territory, utility market, property fit, capacity and duplicate suppression must resolve in one decision.
QENTRAX RESEARCH · AUGUST 2026
Solar routing looks simple until a homeowner can be technically valid and still be impossible—or uneconomic—for a particular installer to serve. Several constraints have to resolve at the same moment.
Territory is only the beginning
ZIP and state coverage establish a basic service boundary, but utility market, property characteristics and campaign-specific homeowner requirements can materially change buyer fit.
Capacity changes in real time
A buyer that wants a market this morning may hit a daily cap this afternoon. Routing should consider current capacity and operating rules rather than relying on a static buyer list.
Duplicates distort economics
Repeated distribution wastes buyer attention and damages publisher economics. Duplicate suppression should happen before bidding wherever possible, using appropriate identifiers and time windows.
One decision, multiple signals
The practical solution is a decision layer that resolves territory, property fit, capacity, duplication and price together, then returns a clear route or rejection reason.
