Proprietary Information Of Energy 2013
Overview
• Solar Feasibility (Is solar an option?)• Mounting Options• Things to consider• Module Options• Inverter Options• Interconnection Options• Purchasing Options (PPA vs. Owner Finance)
Proprietary Information Of Energy 2013
Solar Feasibility
• Geographic Location (Peak Sunlight Hours)• Utility Costs• Utility Rate Structure• Overall Goal• Probable Locations/Interconnection• Incentives• Funding Options
Proprietary Information Of Energy 2013
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

Things To Consider
• Accessibility• Roof Condition/Warranty• Interconnection Points/Voltage• Source/Load Management
Proprietary Information Of Energy 2013
Module Types
• Traditional Silicon Wafer Modules– Monocrystalline– Polycrystalline
• Thin Film (Amorphous)• Specialty
Proprietary Information Of Energy 2013
Inverter Options
• Centralized Inverters• String Level Inverters• Micro Inverters
Proprietary Information Of Energy 2013
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
Proprietary Information Of Energy 2013
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
