Solar Resource Assessment

Prior to planning a solar energy project it is essential to determine where the abundant resources exist. We provide maps, data and tools for prospecting and couples this with resource measurement programs and reporting so you can have a better understanding of site characteristics and validate the quality of the site. 

As the size and complexity of projects increase, the right mix of technology to measure the resource becomes critical. Our full-service resource assessment program can support your team in the following areas: 


  • Solar resource maps and data: We offer solar resource maps and data for all stages of project development. We use a combination of satellite data, mesoscale modeling, and surface measurements to produce accurate and detailed maps for site screening and feasibility studies. Time series data are available for modeling plant output and performing short-term climate corrections. 


  • Solar measurement campaigns: The solar industry is coming around to our long-standing view that on-site measurements are needed to provide the necessary accuracy for energy production estimates. Our engineers can design your solar monitoring campaign to fit your budget and priorities, and will arrange, oversee, and verify equipment installation to exacting standards. Our smart approach assures the greatest confidence for the smallest practical investment.  


  • Data management and quality control: GRL, through our partnership with UL, offers a comprehensive one-stop solution to managing your solar data safely and securely. We will collect the data, apply rigorous QC tests to detect problems such as malfunctioning equipment, and provide regular data summaries. 


  • Resource analysis and reports: Our staff meteorologists are highly experienced in analyzing solar resource measurements. We will validate your data, correct for site conditions, adjust for short-term climate, and provide a comprehensive report to support development decisions.
