How to Design Stormwater Management for Ground Mounted Solar Arrays

Steven D. Trinkaus, Professional Engineer

In the legislature push in Connecticut and other states for more renewable energy, such as solar arrays, many environmental considerations are being minimized or flat out ignored by the regulatory agencies responsible for protecting the environment. The installation of large ground mounted solar arrays have caused many adverse impacts during and after development as a result of stormwater from these sites. This presentation will highlight what the particular issues are and how they need to be addressed during the design and construction period.

Learning Objectives: 

  • Learn how assumptions about soil properties and extent of vegetation used in the design phase of stormwater management systems for ground mounted solar arrays can cause adverse environmental impacts.
  • Understand what design assumptions are appropriate for developing and modeling stormwater management systems for ground mounted solar arrays.
  • See the results of the adverse impacts on the environment of incorrect assumptions in the design of stormwater management associated with ground mounted solar arrays.
