1. November 9th, 2009 Solar Energy for Affordable Housing Presented by: Eric Nyman

2. Benefits of Solar for Multi-Family Housing Significantly Reduce Long Term Energy Expenses Meet Local Mandates Improved Energy Efficiency Requirements (T-24) Improved Eligibility for Additional Tax Credits Add marketability to your project

3. Solar Basics Produces electricity directly from sunlight No moving parts, very low maintenance Clean, quiet, sustainable Estimated 30 year system life Photovoltaics (PV)

4. Key Considerations for PV Available roof space – non shaded Sizing, based on load estimates Structural issues, 4 lbs./sq.ft. Electrical issues, ability to interconnect into main switch gear New construction or retrofit Available space for Inverters, Disconnect switches, etc.

5. Economics of PV State mandated incentives 30% Federal ITC MACRS accelerated Federal Depreciation and straight line State Depreciation In some cases, local additional incentives System warranted for 10 years with estimated 30 year life ROI between 8-15+% after tax

6. Choosing the Correct Utility Rate Tariff Multiple rate schedules available TOU Time of Use –Different value for electricity based on time of day, day of the week, and season –Often the best choice for multi-family housing Traditional rate schedules –Either tiered or significant demand charges –Often the best choice if PV system represents a small percentage of total common load

13. Solar Basics Circulating liquid through insulated collectors on the roof Heated water stored in tanks to support boilers Controls activate pump to capture maximum heat gain Clean, quiet, sustainable Solar Water Heating (SWH)

14. Key Considerations for SWH Sizing, based on building occupancy and use Structural issues, 4.5 lbs./sq.ft. New construction or retrofit Space available for storage tanks, which can be significant in larger systems Collectors ideally tilted at 35-40 degrees

15. Economics of SWH State mandated incentives effective 1-1-2010 30% Federal ITC MACRS accelerated Federal depreciation In some cases, local additional incentives System warranted for 1-3 years with estimated 25 or more year life cycle ROI between 10-17+% after tax

21. CSI California Solar Initiative –Existing Buildings –Up front rebate or performance based incentive (PBI) over 5 years NSHP New Solar Homes Partnership –New Construction, Single or Multi-Family –Up front rebate and currently the highest incentive –Must exceed T-24 by at least 15% MASH Multi-Family Affordable Solar Homes –Retrofitting multi-family affordable housing –Currently oversubscribed California Solar Incentives
