EPC Construction Checklist for Customer PPA Financing

Tax equity and the use of Power Purchase Agreements is a great way to help your clients obtain solar energy without hefty upfront costs or risk that may deter them.

 

This page provides an overview of the items we typically request from our EPC partners during the construction process when tax equity is involved. Nearly all of the checklist tasks are ones you're already doing internally, so it is as simple as a quick send over to us.

 

This is a sample of the most commonly requested items, but each project is slightly different.
