A solar site surveyor is the person who visits a home or building before anything is designed or sold for certain, and comes back with the facts: roof dimensions, rafter size and spacing, roof condition, main panel details, shading, and anything that will make the job harder than the sales proposal assumed. Companies call the role site surveyor, site assessor, site technician or site auditor. Whatever the title, it is one of the cleanest ways for an installer to move off the roof most days without leaving the field, and a common first step toward design work.
What a solar site surveyor does
The survey sits between the sale and the design. A sales rep may have produced a proposal from satellite imagery and a utility bill. The surveyor confirms or corrects it in person, so the designer can build a plan set that will pass permit review and match what the install crew finds.
O*NET's profile for Solar Sales Representatives and Assessors lists the assessment side of the work as checking whether sites are suitable for solar using tools like tape measures, compasses and software, and calculating likely production based on climate, shading and roof orientation. On engineering-led teams, the equivalent task in the Solar Energy Systems Engineers profile is conducting site audits to collect structural, electrical and related information.
In practice, a residential surveyor's day might include two to four homes, each involving time on the roof, in the attic, at the main electrical panel and at the utility meter, followed by uploading photos, measurements and notes to the company's design system.
What a solar site survey captures: a checklist
Every company has its own form, but most residential surveys cover the same ground. If you are applying for a surveyor role, being able to talk through this list is the interview.
Roof and structure
- Roof planes: dimensions, pitch and orientation for every plane that might hold modules
- Roofing material and condition, layers of roofing, and soft or damaged spots
- Attic access, rafter or truss size, spacing and span, and any signs of sagging, rot or prior repairs
- Obstructions: vents, skylights, chimneys, satellite dishes, plumbing stacks
- Fire setback areas and pathways the local code may require
Electrical
- Main panel make, bus rating and main breaker rating, plus clear photos of the label
- Open breaker spaces and the general condition of the panel
- Meter location, utility meter number and service entrance type (overhead or underground)
- Possible routes for conduit from the array to the inverter and point of connection
- Locations for inverter, disconnects and, if included, a battery
Shading and site
- Trees, neighboring buildings and other obstructions, often with a shade tool or app reading
- Ladder placement and access for the crew, parking and equipment staging
- Anything the homeowner mentioned that the proposal did not account for
Photos are the deliverable. A designer working remotely can only use what you captured. One blurry panel label can delay a whole job. Shoot every label straight on, get a wide shot and a close shot of everything, and photograph the rafters with a tape measure in frame.
Why installers make good site surveyors
An installer has already lived through the consequences of a bad survey: the rafter spacing that did not match the plan, the main panel that could not take a backfeed breaker, the roof that needed replacing before anyone could mount on it. That experience is what companies are buying when they hire a surveyor from a crew.
Specifically, installers already know:
- how to move safely on a roof and set up fall protection, which is still part of most survey days;
- what an attic crawl actually takes, and what a weak rafter looks like;
- which panel conditions turn into a service upgrade;
- which details the crew needs that a designer might not think to ask for.

Common site survey mistakes that cost a job
Most survey failures are not dramatic. They are small omissions that show up weeks later as a redesign, a permit correction or a crew sent home. The ones installers see most often:
- Measuring one rafter bay and assuming the rest. Additions, old repairs and mixed framing are common. Check spacing in more than one spot and note any change.
- Skipping the attic. If access is blocked, say so in the notes instead of guessing. A designer can plan around a known unknown; a guess becomes a change order.
- Missing the second layer of roofing. Count layers at an edge or vent. It affects attachment length and sometimes whether the job can proceed at all.
- Incomplete panel photos. Without the label, the bus rating and the breaker layout, the designer cannot decide how the system ties in.
- Not writing down what the homeowner said. A planned reroof, a tree they intend to cut or a future EV charger changes the design.
A surveyor who avoids these consistently becomes the person the design team asks for by name, which is exactly the reputation you want when a design opening comes up.
Who hires solar site surveyors
- Residential installers. Larger companies often have dedicated survey teams. Smaller ones fold the survey into the lead installer's or salesperson's job.
- Design and engineering service firms. Companies that sell plan sets to installers sometimes run field survey teams or contract them out.
- Commercial and utility-scale developers. Site assessment on larger projects shifts toward structural engineering, geotechnical work and surveying in the land-surveyor sense, which usually requires different qualifications.
- Utility and incentive programs. Some programs use field technicians to verify installed systems.
Search terms that turn up these jobs include "solar site surveyor", "site assessor", "site survey technician" and "field technician solar survey". Our guide to where solar installers find work covers the job boards worth checking.
Pay, schedule and what changes from installing
There is no separate Bureau of Labor Statistics wage category for solar site surveyors. Installers, for comparison, earned a median of $25.55 an hour in May 2025. Be skeptical of salary sites quoting a precise national figure for the surveyor title; the job is defined differently from company to company, and some versions are closer to sales while others are closer to engineering.
What changes from installing:
| Installer | Site surveyor | |
|---|---|---|
| Work unit | One or two jobs per day as a crew | Several homes per day, often solo |
| Roof time | Most of the day | Shorter visits per home, plus attic time |
| Driving | To one site | Between several sites |
| Customer contact | Limited | Constant; you are often the first technical person they meet |
| Computer work | Minimal | Uploading photos and data, sometimes basic layout in design software |
| Mistakes cost | Rework on the roof | Redesign, permit delays and change orders |
Ask any employer how the role is paid. Some pay hourly, some pay per survey, and some pay surveyors who also sell on commission. If it is per survey, ask how many surveys a typical day includes and whether drive time between them is paid. The same questions we cover in how solar installers get paid apply.
Credentials that help
No national license exists for solar site surveyors. Helpful credentials include:
- OSHA 10 or 30 for Construction, since you will still be on roofs and in attics.
- NABCEP PV Technical Sales (PVTS), which NABCEP describes as covering prospect qualification, site and performance analysis and incentive advice. NABCEP does not currently list a stand-alone site assessor certification, so be wary of training providers that sell one as an industry standard.
- NABCEP PV Installation Professional (PVIP), if you already have the install hours. It signals you know what the crew needs. See our NABCEP certification guide.
- Design software familiarity. Even basic comfort with the layout tool your target employer uses makes you more useful.
Where the site surveyor role leads
Survey work is a bridge. People who do it well often move into:
- PV design and permitting, because they already understand what the designer needs and why.
- Project coordination or management, because they have dealt with customers, crews and paperwork at once.
- Technical sales, for those who like the customer side.
- Quality and inspection roles, because they know what a correct site looks like.
Keep copies (with your employer's permission) of a few clean, well-documented surveys with customer details removed. When you apply for a design role, showing the quality of your field data is stronger than any line on a resume.
Bottom line on solar site surveyor jobs
If you have a year or two of install experience, a sharp eye and patience for paperwork, a solar site surveyor job gets you off the roof part of the day, puts you in front of customers and designers, and sets up a move into design or project roles. Before you take one, find out whether the role is closer to sales or to engineering at that company, how it is paid, and whether drive time counts. Then make your photos and measurements the best the design team has ever received.
