Solar Feasibility Geographic Location (Peak Sunlight Hours) Utility Costs Utility Rate Structure Overall Goal Probable Locations/Interconnection Incentives Funding Options
Mounting Options • Roof Mount • Flat (Rubber) • Ballast • Mechanically Attached • Slope (Standing Seam/Shingle) • Mechanically attached • Pentrating vs. Non-Penetrating • Structural/Wind Loading Considerations • Warranty Concerns
Mounting Options • Ground • Ballast • Fixed Tilt • Top of Pole • Tracking • Single Axis • Dual Axis • Parking Canopy
Things To Consider Accessibility Roof Condition/Warranty Interconnection Points/Voltage Source/Load Management
Module Types • Traditional Silicon Wafer Modules • Monocrystalline • Polycrystalline • Thin Film (Amorphous) • Specialty
Traditional Silicon Modules Mono Poly
Specialty Transparent/Frameless
Specialty Flexible
Inverter Options Centralized Inverters String Level Inverters Micro Inverters
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
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
