As part of the realignment with the Main Line Program the sites eligible for Funding has been expanded to include additional roof types, but also subject to an expanded amount of scrutiny.

Please review closely the Eligible Site article and direct your attention to the key differences:

  • Section B - Eligible Roof Types now include a variety of pitched and flat roof types, BUT these additional types include updated quality standards.

  • Section C - Eligible Home Types/Mounting Structures are still limited to Single Family Homes with full ownership and no shared portions of the structures.

  • Section E - Second Systems and Add Ons are strictly prohibited.

Failure to closely adhere to the expanded guidelines in the Main Line Program will result in a disqualification of projects.
