4. Residential PV: Largely Cash Purchase Business
Residential:
Historically cash purchase
Alternative financing models just getting
started: PACE and power purchase
agreements
Characterized by upfront incentives
Standard Solar, Silver Spring, MD Higher installation costs, but offsetting
highest electricity cost
Net metered, grid tied systems most
common
Less cost sensitive customer
Key challenges: upfront investment, HOA,
complexity for home owner

5. Commercial/Industrial: Dominated by Power
Purchase Agreements
Commercial/Industrial:
90% of commercial/industrial done via
power purchase agreements (PPAs)
Characterized by output based incentives
(PBI, SREC)
Economies of scale drop installation costs,
but offsetting lower electricity rates
SunEdison, Kohl’s Laguna Niguel, CA
Customer is very cost sensitive
Provides the benefit of distributed
generation
Interconnected on customer side of the
meter
Roof or ground mount
Key challenges: financing, net metering

6. Utility Scale: Power Purchase Agreements or
Ownership
Utility:
Ownership models driven by state
regulations
Competing against wholesale power rates
Greatest economies of scale but incurring
earthwork and foundation costs
Interconnected on the utility side of the

12. Declaring a state open for solar business
Typical market signals required:
• State incentive structure that encourages private financing
• Ability to secure long-term contracts
• Market demand (RPS)
• Net metering
• Interconnection standards
• Appropriate tax structure
• Zoning/permitting standards
• Incentives designed to meet three separate residential, commercial and utility-
scale business models
• Allow 3rd party developers

15. Davidson County Lessons Learned
• Large projects = long timelines
• State tax incentive limits investment, doesn’t encourage it
• Anticipate market/legislative changes
• Utility/developer/legislative/PUC partnership is critical
• Create repeatable template
• Maintain tight control over supply chain
• Non issues:
– Technology
– Skilled labor
