DESCRIPTION

Shared solar is one option for energy consumers who want to benefit from the sun's power but don't have the rooftop for it. Only about 25 percent of residential rooftops are capable of hosting solar generation systems. IREC has helped develop shared solar programs across the country. Hear from Erica McConnell about what's working and what’s on the next horizon.

Why Shared Solar?

I want to benefit from renewable energy generation, but I…

– Rent my apartment– Live in a multitenant building (e.g., a condo)– Have insufficient or problematic roof space

(e.g., too shady)– Am just not interested in on-site generation

(maintenance responsibility, aesthetic issues, etc.)

Only 25% of residential roofs permit on-site generation

Serving More Energy Consumers

If just 5% of U.S. households invested in a 5-kW interest in a shared solar system…

… we’d see over 28 GW of additional solar capacity!http://quickfacts.census.gov/qfd/states/00000.html

Critical Program Elements

1. Allocating the benefits of participation

2. Valuation of the energy produced

3. Program administration

4. Shared solar facility ownership

5. Shared solar facility size and location

Additional Considerations

• Number of program participants• Minimum and maximum subscription sizes• Portability and transferability of participation• REC ownership• Consumer protection• And more…

Ultimately, the community’s goals, priorities and constraints determine

what the program looks like11

What’s Next?

• Programs nearing implementation:– Minnesota Community Solar Gardens– Washington, DC Community Renewable

Energy Facilities– California Green Tariff Shared Renewables

programs

– Utility-level projects and programs

What’s Next?

Policy considerations—how can we:• Maximize grid benefits and minimize

interconnection costs?– Interaction with distribution planning and

interconnection procedures

• Reach more low- and moderate-income consumers?– Interaction with financing opportunities
