Solar Power

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)


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

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 ModulesMono Poly


Thin Film (Amorphous)CIGS


SpecialtyTransparent/Frameless


SpecialtyFlexible


Inverter Options

• Centralized Inverters• String Level Inverters• Micro Inverters


Centralized Inverters


String Level


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
