Site Survey

A site survey is an on-site evaluation of your property conducted by a solar installer (or technician) to gather the detailed information needed to finalize the system design. It is typically performed after you’ve received an initial proposal and before the final contract is signed.

During the site survey, the technician will: examine the roof condition, age, and material; measure roof dimensions, pitch, and orientation; identify obstructions (vents, chimneys, skylights, satellite dishes); perform a shade analysis using specialized tools; inspect the main electrical panel (brand, age, amperage, available breaker spaces); check the utility meter configuration; evaluate the path for conduit runs from the roof to the panel; assess attic access and rafter spacing for structural attachments; and take photos documenting all findings. The site survey may reveal conditions that weren’t visible from satellite imagery — such as roof damage that needs repair, an undersized electrical panel requiring an upgrade, or shading from nearby structures. These findings can lead to adjustments in the system design or additional costs. A thorough site survey is the best protection against unexpected change orders and installation delays.
