Rooftop PV is Increasingly Affordable
5
But… Deployment of Rooftop PV is Constrained by Other Factors × I’m a renter × I expect to move to a new home soon × I can’t get financing × My rooftop isn’t suitable

My Rooftop Isn’t Suitable!
Only 22-27% of Residential Roof Area is Suitable for PV

Community Solar Addresses the Biggest Non-Cost Constraints Credits can attach to your bill, even if you rent, and move with you to a new location (in the same utility’s service territory) Some programs provide access to nomoney-down, low-interest, no-fee financing Community projects are sited in suitable/optimal locations 8
Public Policy Challenges
9
Key Challenges for Community Solar • Laws, regulations or utility commission decisions limit who can offer it • Net metering/solar tariff design: – Can make community solar contrary to utility’s or customer’s self-interest – Can lead to undue cross-subsidies
• Retail rate design: – Can undermine cost-effectiveness/add risk 10
Where are the programs?
3rd Party Solar PV Power Purchase Agreement (PPA) www.dsireusa.org / March 2015
RI: May be limited
IA: See notes
to certain sectors
NV: With system size limitations
CO: With system UT: Limited to size limitations certain sectors
DC VA: Limited within a certain utility's service territory
AZ: Limited to certain sectors TX: With system size limitations
At Least 24 States U.S. Territories PR
Guam
USVI
NMI
Apparently disallowed by state or otherwise restricted by legal barriers Authorized by state or otherwise currently in use, at least in certain jurisdictions Status unclear or unknown
+ Washington DC and Puerto Rico Authorize or Allow 3rd Party Solar PV Power
Customer Credits for Monthly Net Excess Generation (NEG) Under Net Metering www.dsireusa.org / March 2015
DC
NEG at retail rate (or above); credits do not expire
NEG at less than retail rate (e.g., avoided cost rate)
NEG at retail rate at first, then credits expire or are reduced (e.g., to the avoided cost rate) after set period of time
NEG at $0
No uniform or statewide mandatory net metering rules

Keys to Long-Term Success • Authorization: explicitly allow community solar programs (utility, 3rd party, or both) • 3rd Party Siting: involve the utility • Solar Tariffs: customers should receive fair and just compensation for the power they supply – no more and no less • Subsidies: if any, should be provided outside of the utility bill (e.g., tax credit) 15
More Keys to Long-Term Success • Rate design: – Customers should be able to connect to the grid for no more than the cost of connecting to the grid – Customers should pay for grid services and power supply in proportion to how much they use, and when they use it
• Consider utility incentives and decoupling utility revenues from sales 16
