  • 1. Solar for All: Including Renters and Condo Owners Bruce Karney July 8, 2009 bkarney@comcast.net
  • 2. Agenda  What’s the problem?  What’s the solution?  Why adopting Solar for All is urgent  Why solar leasing is critical  How homeowners benefit too 2
  • 3. What’s the problem?  All residential electricity customers pay into the solar rebate fund  For all practical purposes, only single family homeowners can receive a residential solar rebate 3
  • 4. Not a homeowner? Ride back here Solar Bus 4
  • 5. Single family homeowners are a minority in California 4% Owner occupied single family home Owner occupied condominium 38% 45% Renters Mobile home 13% 5
  • 6. … but a privileged one  Households earning less than $50,000 – 41% home ownership rate  Households earning $150,000 or more – 87% home ownership rate 6
  • 7. Biggest residential CSI rebates 1. $375,215 for 210 kW in Atherton 2. $319,188 for 200 kW in Newcastle 3. $238,358 for 156 kW in Napa 4. $137,895 for 69 kW in Woodside 5. $137,216 for 62 kW in Bishop 7
  • 8. What’s the solution? 8
  • 9. Solar for All  Allow ALL residential customers to offset their bill – just like homeowners already can – with power generated by equipment they own at “solar farms”  Allow solar farm customers the option to lease their equipment – just like homeowners already can  Authorize Remote Net Metering for solar farm customers 9
  • 10. Solar farms can be urban or rural 10
  • 11. Low-cost “commercial solar” technologies are welcome  Divisible into < 6 kW sub-systems  CSI-eligible Solyndra Cool Earth Lumeta Skyline Solar 11
  • 12. What is Remote Net Metering?  Energy consumption measured by one meter  Energy generation measured by another meter  Meters separated by miles, not feet  Generation subtracted from consumption to determine the bill 12
  • 13. Example: January The Gomez family used $88 of electricity in their apartment Their portion of the solar farm generated $30 of electricity Their net bill is $58 13
  • 14. Example: July They used $65 of electricity Their portion of the solar farm generated $115 of electricity This gives them a credit of $50 for the month 14
  • 15. Everything balances over the year $60 Bill $40 $20 Monthly bill $0 or credit Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec -$20 -$40 Credit -$60 15
  • 16. Economies of scale: 4 kW of PV Single 1,000 kW Percent Family Solar Farm Improve- Roof ment Price per DC kW $7,500 $6,000 20% Price for 4 kW (DC) system $30,000 $24,000 20% CSI incentive ($5,000) ($5,000) Federal Tax Credit ($7,500) ($5,700) Net Price $17,500 $13,300 24% 16
  • 17. Better siting improves output Single 1,000 kW Percent Family Solar Farm Improve- Roof ment Net Price $17,500 $13,300 24% Avg. kWh per DC kW per year 1,250 1,450 16% kWh produced over 30 years 150,000 174,000 16% $ / kWh $.117 $.076 35% (ignoring time value of $) $ / kWh $.225 $.148 34% (assuming 5% discount rate) 17
  • 18. Precedents  Sacramento: SolarShares  City of Alameda: separate meters measure generation and production  SoCal Edison: putting 150 giant PV systems on large commercial roofs – All utility-owned, none customer-owned  MA: Neighborhood Net Metering 18
  • 19. Why adopting Solar for All is urgent 19
  • 20. Million solar roofs: 3 programs  CPUC: CSI program $2,167 Million, 1,940 mW, PG&E, SCE & SDG&E territory, existing homes, new & existing commercial, government, agriculture  Publicly Owned Utilities, $784 Million, 700 mW, all systems in POU areas  CEC: NSHP program, $400 Million, 360 mW, IOU territory, new homes  Total: $3,351 Million, 3,000 mW 20
  • 21. CSI program  1/1/2007 – 12/31/2016 7 ½ years left  General Market Program (1,750 mW) – 1,173 mW non-residential (67%) – 578 mW residential (33%)  Low Income Programs (190 mW) – 95 mW Single Family (50%) – 95 mW Multi-family (50%) RNM allowed!  Over half of PG&E residential “General Market” incentives are already paid or reserved 21
  • 22. Rebates are going fast SCE SDG&E PG&E $3.00 $2.50 $2.00 $1.50 2 3 $1.00 4 5 $0.50 6 7 $0.00 8 9 10 0 100 200 300 400 500 Cum. mW Residential PV 22
  • 23. 578 mW = 1 million roofs?  144,500 at 4 kW per system  About 10 million housing units in CSI territory  1.5% will benefit from solar rebates – 3% of single family homes – 0% of renters and condo owners 23
  • 24. Why solar leasing is critical 24
  • 25. Eligibility for 30% tax credit  ITC eligibility for customer-owned equipment at a Solar Farm is questionable  “Qualified solar electric property expenditure" means an expenditure for property which uses solar energy to generate electricity for use in a dwelling unit located in the United States and used as a residence by the taxpayer. 25
  • 26. Do any residential systems qualify? Example: 77% of generation is exported! Example of daily solar generation & energy consumption 25 kWh of Solar Generation 25 kWh of Consumption 5 4 Kilowatts 3 2 Exported 1 0 1 3 5 7 9 11 13 15 17 19 21 23 Hour of day 26
  • 27. No uncertainty about leased systems  There are no federal tax issues with the leased version of Solar for All 27
  • 28. Solar leasing value proposition $195 per month $200 $200 $30/mo. Savings $150 $150 $100 Old Electric Bill $100 Lease Payment $50 $50 New Electric Bill $0 $0 $500 $400 Savings $300 $200 Lease Payment $100 New Electric Bill $0 2009 2014 2019 2024 28
  • 29. Current price for leased solar 50¢ Cents per Kilowatt-hour 25¢ Leased PV today – 21-25 ¢ Tier 3 Tier 4 Tier 5 Tier 1 Tier 2 13.1¢ 26.0¢ 37.9¢ 44.1¢ 11.5¢ 100% 200% 300% 400% Percent of Baseline Electricity Usage 29
  • 30. Solar for All: Lease PV for 15¢/kWh 50¢ Cents per Kilowatt-hour 25¢ Leased PV at Solar Farm: 15¢ Tier 3 Tier 4 Tier 5 Tier 1 Tier 2 13.1¢ 26.0¢ 37.9¢ 44.1¢ 11.5¢ 100% 200% 300% 400% Percent of Baseline Electricity Usage 30
  • 31. How homeowners benefit too 31
  • 32. Solar for All solves homeowners’ most common concerns 1. Aesthetics 2. Worries about roof warranty or leaks 3. Roof replacement needed soon 4. Outdated service panel or other “adders” 5. Too much shade 6. Roof poorly oriented or pitched 7. Concerns about roof strength 8. “What happens when we move?” 32
  • 33. Size of the homeowner market 23,400 homeowners have bought PV under the CSI program ~ 117,000 What fraction would homeowners have sign up for Solar for gotten a site visit but All? NOT purchased yet 1/5 = 23,400 1/3 = 39,000 1/2 = 58,500 * Assume 1 win per 6 site visits 33
  • 34. The future of Solar for All  Assemblyman Paul Fong has agreed to introduce legislation!  Kudos to: Monica Smith and Andrea Graham of his staff  How you can help… – Provide your contact information to Assemblyman Fong’s office: Monica.Smith@asm.ca.gov 34
