Solar Grading
Verification
Document solar site earthwork grade against EPC design — shot by shot, section by section. GPS-tagged, deviation-flagged, and shareable with your EPC before pile driving begins.
What it does
Real-time pass/fail on every shot
- Compare as-built elevation vs EPC design grade at entry
- Configure tolerance per job — ±0.10 ft or tighter for critical zones
- Out-of-tolerance shots flagged red immediately in the field
- Resolve deviations before moving equipment to next area
GPS metadata on every data point
- GNSS fix quality, HDOP, satellite count, and correction age on every shot
- Northing, easting, and elevation stored per point
- Shot map: GPS-located dots color-coded pass/fail
- Defensible record for EPC conformance documentation
EPC-ready as-built reports
- Shot table: design vs as-built elevation, deviation, pass/fail
- GPS coordinate grid for each point
- PDF formatted for EPC submittal
- Share link — EPC approves without a site visit
Import from any instrument
- CSV from Topcon MAGNET Field, Trimble Access, Leica Captivate
- RTK rover output files directly importable
- Generic CSV with column mapping
- Offline capture, batch import on return to connectivity
How it works
01
Set up your solar job
Enter design elevations from the EPC civil grading plan. Configure the grade tolerance per the EPC spec — typically ±0.10 ft for earthwork.
02
Log grade shots as work progresses
Enter as-built elevations shot-by-shot. Gradelog calculates the deviation and flags pass/fail instantly — no spreadsheet math needed.
03
Address deviations
Out-of-tolerance shots show deviation amount and direction. Photograph and note corrective action. Reshoot after rework to confirm.
04
Generate and share the as-built
Generate the grade verification report. Share the link with your EPC. They approve and pile driving can begin on that section.
Common questions
What grade tolerances are used on solar construction sites?
Solar site earthwork grading typically requires ±0.10 ft for general site prep and drainage grades. Tracker row centerlines and pile locations often require tighter tolerances (±0.05 ft) because pile-driving equipment needs a level working surface and final design grades affect drainage across the array. EPC civil specifications vary — Gradelog lets you configure tolerance per job.
Why does grade verification matter for solar EPC contractors?
EPC contractors require documented grade conformance before authorizing pile driving on each section of the site. Without a verified as-built earthwork grade, pile depths and cutoff elevations may not match design, requiring expensive corrections after racking is started. Grade verification documentation also protects the grading subcontractor if pile issues arise later.
Can I import grade shot data from a total station or RTK rover?
Yes. Gradelog imports CSV files from Topcon MAGNET Field, Trimble Access, Leica Captivate, and Spectra Precision. If your crew is using an RTK rover on the solar site, export the grade check points as CSV and import them into Gradelog — no re-keying of survey data.
How does Gradelog work without cell service on remote solar sites?
Gradelog is offline-first. Crews log grade shots in the field with no cellular connection. All data queues locally and syncs automatically when the device reaches coverage. Nothing is lost — no duplicate entries are created on sync.
