Energy Assessment
Yield assumptions get locked into financing before anyone measures the site. GroundWork establishes the ground truth baseline lenders require — before capital flows.

GroundWork delivers uncompromising solar data quality through precision measurement and world-class services .
At GroundWork we take pride in providing the highest quality reference solar data.
The GroundWork Zenith MET System is a revenue-grade weather station that provides the best solar plant reference data to increase the accuracy of solar power performance modeling.
GroundWork offerings during the construction phase of solar power plants include:
- MET system design engineering services
- Equipment supply, fabrication and testing
- Installation and commissioning of MET systems and reference sensors
- System design and submittals
Zenith MET System complies with the IEC 61724-1 international standard and includes options for:
- Orbit array-mounted packages for Plane of Array and Rear Plane of Array Irradiance measurement
- Albedo measurement
- Snow depth, hail, and other ancillary MET measurements
- Eclipse soiling measurement for full-sized modules and effective irradiance measurement
- Fracsun ARES for self-cleaning soiling measurement
The Zenith MET is a mission-critical weather station that increases the accuracy of solar plant performance modeling. It offers the highest MET data accuracy and availability in the utility-scale solar industry for the lowest installation and maintenance costs.
The GroundWork Zenith MET System offers Orbit Array Package options to measure plane of array, rear plane of array, and back-of-module temperature to meet PPA, ISO and owner/operator requirements.
The GroundWork Eclipse PV Module Measurement System delivers site-specific soiling and effective irradiance data. The Eclipse measures short-circuit current, open-circuit voltage and back-of-module temperature from a pair of full-size modules.
GroundWork offers a stand-alone albedo measurement system to characterize surface reflectivity for the operating plant. Albedo measurement provides a site-specific input for monitoring bifacial systems.

Defensible certainty before decisions become irreversible — from development through operations
Performance Test
Acceptance is when liability transfers from EPC to owner. GroundWork validates what you're accepting before schedules force the decision.
Plant Monitoring
Undetected performance loss without proof is unrecoverable. GroundWork provides the baseline to find it while remedies still exist.
Extreme Weather
When hail hits, insurance claims and warranty disputes follow. GroundWork provides independent event documentation and lab testing that holds up under scrutiny.
Module Performance
Not all modules perform as rated. GroundWork verifies the watts you paid for, so performance has a paper trail.
