2. Solar is expensive at roughly $7,000/kilowatt (or $0.45/kWh) On a typical solar project, the federal tax incentives pay for more than 1/3, local or state incentive programs pay for 1/3 and the last 1/3 comes from debt or owner equity. As tax-exempt entities, universities cannot receive the federal Investment Tax Credit/Grant and bonus depreciation on a purchase. Tax Exempt Entities have to look to more creative structures, such as PPAs, in order to monetize the tax credits. Without monetizing the tax credit, a customer would have to look to another funding source, such as grants or donations to make the system economically viable. Financing Options for Tax Exempt Entities

3. Long term agreement to purchase electricity from a third party financier (PPA Provider) – 20 year terms, predictable cost increases No equipment to purchase, no capital investment No annual maintenance expense, no asset to manage Customers purchase only the power produced by the system A Power Purchase Agreement (PPA)

4. Solar PV works in states with viable incentive programs – Massachusetts – Commonwealth Solar Initiative – California – Production Based Incentive (PBI) – New Jersey – SREC program – Others include Connecticut, New York, Pennsylvania, Arizona, Colorado, New Mexico, Oregon and Hawaii The ARRA Stay tuned – incentive programs are evolving. State Solar Programs
