Energy Assessment
Yield assumptions get locked into financing before anyone measures the site. GroundWork establishes the ground truth baseline lenders require — before capital flows.
Plant Monitoring
GroundWork delivers uncompromising solar data quality through precision measurement and world-class services throughout the lifecycle of utility-scale solar power plant development, construction, and operation. GroundWork offers ongoing services during plant operations to ensure the availability and accuracy of operating plant reference data.
Pyranometer Management Program (PMP)
Sensors enrolled in the PMP will be calibrated at ISO-CAL North America, a calibration laboratory in Prescott, AZ, in compliance with the latest ISO and ASTM standards. The PMP includes schedule management, asset tracking, spare inventory purchase consultation, and spare inventory storage to ensure that pyranometers are continuously calibrated with minimal downtime and cost to our clients.
Pyranometer calibrations
Sensors will be calibrated at ISO-CAL North America, a calibration laboratory in Prescott, AZ, in compliance with the latest ISO and ASTM standards. GroundWork will manage shipping to and from the project site.
Sensor spares
GroundWork will develop a Spare Pyranometer Plan with recommendations, intake, and ongoing inventory management. Depending on the size of the total client pyranometer fleet, GroundWork will determine the minimum number of sensors required to maintain rolling calibration exchanges across all sites and supply the equipment to the site.
Service calls
As needed, GroundWork will visit specific sites upon client request to provide training to plant operations personnel, remedy equipment issues, or complete other required tasks.
Reference sensors are maintained in compliance with the latest ISO and ASTM standards.
GroundWork is the market leader for solar operating plant reference data.

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.
