Resource Assessment for Solar Development

Groundwork performs turnkey solar resource assessments prior to construction to provide inputs for PV energy modeling. The quality of the Company’s ground datasets is unparalleled and quantified through published research and accompanying reports and metadata. Over sixty gigawatts of solar plants have used GroundWork’s high-quality ground data to get projects built. Our revenue-grade measurement data is specifically designed to achieve our clients’ goals of reducing the uncertainty of the energy production forecast.

GroundWork datasets include global horizontal irradiance (GHI), PV soiling rates, albedo, diffuse horizontal irradiance (DHI), and other ancillary measurements.

The cornerstone of GroundWork solar resource datasets is our GroundWatch Data Quality Program. By combining rigorous onsite maintenance with meticulous daily quality control, our datasets are second to none.
