Sponsored by ASCE Continuing Education and the 
Structural Engineering Institute (SEI).

INSTRUCTOR:  Michael O'Rourke, Ph.D., P.E., F.SEI, M.ASCE

Purpose and Background

As the country moves towards greener and renewable energy sources, more and more roofs are now equipped with solar panels. One expects the presence of solar panels potentially to change the exposure of the roof, increase the potential for sliding loads and possibly to act as obstructions behind which snow drifts can form. Unfortunately ASCE 7 neither currently addresses any of these snow issues, nor provides overall guidance for the snow loads one expects on solar paneled roofs. This webinar provides recommended snow loads for such roofs, which are consistent with the snow load provisions in ASCE 7.

Primary Discussion Topics

  • Solar panel type classification
  • Exposure, thermal and sliding factors for balanced roof loads
  • Non-uniform loads due to snow sliding off inclined panels
  • Windward and leeward drift loads adjacent to panels

Learning Outcomes

After completion of this webinar, structural engineers are expected to be able to determine snow loads for solar paneled roofs.

Webinar Benefits

  • Avoid potential structural performance issues arising from the mistaken use of unrealistically low snow loads for solar paneled roofs
  • Avoid un-necessarily high construction costs arising from the mistaken use of overly conservative snow loads for solar paneled roofs
  • Increase expertize in the structural design of green facilities
  • Increase knowledge base regarding snow loads in general and solar paneled roofs in particular
  • Be in a position to cite authoritative guidelines if questions arise regarding snow loads on solar paneled roofs

Webinar Outline

  • Disclaimer
  • Solar panel types
  • Recommended exposure factor for roofs with flush, tilted or elevated solar panels
  • Recommended thermal factors for solar paneled roofs
  • Recommended slope factors for solar paneled roofs
  • Sliding loads on solar paneled roofs
  • Drift loads for a single row of solar panels
  • Multiple row drift loads for closely spaced panels
  • Multiple row drift loads for widely spaced panels

The Central Ohio Section of ASCE sponsors free continuing education webinars as a service to our members. These webinars are produced by ASCE and normally cost $250 or $300 for ASCE members. However, the Central Ohio Section is paying the registration fee and inviting any interested section members to attend for free. Just RSVP by the deadline. Seating is limited, so do not delay.

The Central Ohio Section is partnering with ASCE to promote live and on-demand webinars. Use the Promo Code WEBCENOHSEC when signing up and ASCE will provide a portion of the registration fee to the Section to use toward more free webinars. Thank you for your support!
