The Solar Site Survey Handoff: What Sales Needs to Know

Where the Site Survey Sits in the Sales-to-Install Handoff

The sequence runs: signed contract, then site survey, then permitting, then interconnection, ending in Permission to Operate. A site survey is the on-site technical inspection that happens after the contract is signed and before permitting (EagleView). Interconnection is the process of physically connecting the system to the grid, and it ends in Permission to Operate, the utility's sign-off that lets the system actually run (Aurora Solar Glossary). Every step in that chain depends on what the survey confirms or contradicts.

What the Survey Actually Checks

A site survey verifies the physical assumptions the proposal was built on: the roof's condition and available space, shading across the property, and whether the home's electrical infrastructure can support the proposed system (EagleView). A remote or preliminary design can estimate all three. Only an on-site survey confirms them.

Why a Survey Mismatch Is a Sales Problem, Not Just an Ops Problem

If the survey reduces the system size, because of shading, panel capacity, or roof constraints the original proposal did not fully account for, the offset percentage and price-per-watt figures presented to the homeowner may no longer hold. That is not a paperwork detail. Both setter and closer commission are paid per watt on the deal that actually gets installed, $0.05 to $0.15 per watt for a setter, $0.20 to $0.50 per watt for a closer (Everstage), so a quiet system-size change downstream is also a quiet commission change, and the rep should hear about it before the homeowner does, not after.

What a Clean Handoff Looks Like

The rep or their team should be looped back in whenever a survey materially changes the deal, not find out after installation. Set a clear internal threshold for what counts as material (a meaningful drop in system size, a financing-relevant change, a shift the homeowner would reasonably want to hear about directly from the person who sold it). A survey and permitting delay also delays Permission to Operate, which delays the moment the referral ask actually lands best. A clean handoff protects the sale, the commission, and the next referral in one motion.
