  18. Traditional Silicon Modules Mono Poly

  19. Thin Film (Amorphous) CIGS

  20. Specialty Transparent/Frameless

  21. Specialty Flexible

  22. Inverter Options Centralized Inverters String Level Inverters Micro Inverters

  23. Centralized Inverters

  24. String Level

  25. Micro Inverters

  26. Interconnection Options • Load Side • Utilize existing Distribution Panel • Typically 480V • Line Side • Grid side tie in at grid voltage • Requires HV transformer • Utility typically specifies additional required safety features. • Typically depends upon system size and location

  27. Financing Options • Power Purchase Agreement (PPA) • Property owner purchases the power at a reduced/premium rate under a long term contract. • Site Lease Agreement • Property owner leases the site to the system owner. System owner must finance the system. • Traditional Financing • Traditional loan • Bond Issue
