  • Johnson’s study in 1983 was the first of its kind, but measured savings from appliances like air conditioners. That’s where the 1:20 factor originated. Nevin used Johnson’s 1:20 ratio and applied to solar. Black and others now use the Nevin study from the Appraisal Institute and quote the 1:20 ratio frequently.
  • Transcript

    • 1. What is Solar Worth? Dr. Mary Beth McCabe National University [email_address] 858 488 2867
    • 2. Growing Solar Markets
      • GSMMBEA (initials from title…rearranged)
      • S olar Marketing Becomes Excellent at Moving Goods
    • 3. What is it worth…insured value?
      • What price will an insurer replace the system?
      • Ex. $20,000 PV system replaced for $20,000.
      Currently PV insurance costs are high (NREL): “ Insurance premiums make up approximately 25% of a PV system’s annual operating expense. Annual insurance premiums typically range from 0.25% to 0.5% of the total installed cost of a project depending on the geographic location of the installation. PV developers report that insurance costs comprise 5% to 10% of the total cost of energy from their installations, a significant sum for a capital-intensive technology with no moving parts.”
    • 4. What is it worth…Real Estate appraisal?
    • 5. What is it worth…parts/used?
    • 6. Auto uses KBB and Edmunds
    • 7. Standards of Excellence
      • Currently many confusing ways to market solar, ex. Efficiency, carbon footprint, reduced energy expense, good feelings, large rebates, right thing
      • Your business uses what “standard” measurement tool?
      • Do customers understand how you market?
    • 8. What to do next?
      • See what’s been done well.
      • See what’s missing.
      • Give answers….simply
    • 9. Solar Appraisal Studies
    • 10. 1983 Johnson, Kaserman Housing Market Capitalization of Energy Saving Durable Goods Investments Considered fixed appliances as durable investments for capitalizing future fuel savings by using utility bill comparisons, sales prices and air conditioners, for example Investing in durable goods that decrease the utility bill should increase the value of the home in 1978 dollars of 1:$20.73
    • 11. 1998 Nevin, Watson Evidence of Rational Market Valuations for Home Energy Efficiency Regression analysis of homeowner-reported property values and utility expenditures. Incremental home value increase of $10-25 for every $1 reduction in annual fuel bills
    • 12. 1999 Nevin, Bender, Gazan More Evidence of Rational Market Valuations for Home Energy Efficiency Regression analysis of realtors’ valuations of home improvements to utility bill savings and energy efficiency Home values increase incrementally for improvements such as low-e windows
    • 13. 2009 Black Economics of Solar Electric for Consumers: Payback and other Financial Tests Clarifies how the 1:20 valuation should be used in the marketplace Agrees with and promotes with conclusion from 1998 Nevin study. Uses the 1:20 valuation in describing real estate values of PV.
    • 14. Summary of studies & how study informs the PV marketing message [1] http://www.renewableenergyworld.com/rea/news/article/2008/03/estimates-guesstimates-obsolete-just-plain-wrong-severin-borensteins-pv-costs-paper-51782 [2] http://votesolar.org/linked-docs/borenstein_response.pdf Year Author(s) Study Title Method(s) used Conclusion/Summary July 1983 Ruth Johnson, David L Kaserman Housing Market Capitalization of Energy Saving Durable Goods Investments Considered fixed appliances as durable investments for capitalizing future fuel savings by using utility bill comparisons, sales prices and air conditioners, for example Investing in durable goods that decrease the utility bill should increase the value of the home in 1978 dollars of 1:$20.73 October 1998 Rick Nevin, Gregory Watson Evidence of Rational Market Valuations for Home Energy Efficiency Regression analysis of homeowner-reported property values and utility expenditures. Incremental home value increase of $10-25 for every $1 reduction in annual fuel bills October 1999 Rick Nevin, Christopher Bender, Heather Gazan More Evidence of Rational Market Valuations for Home Energy Efficiency Regression analysis of realtors’ valuations of home improvements to utility bill savings and energy efficiency Home values increase incrementally for improvements such as low-e windows. April 2006 Rupert Ayton Lost in Transmission: The Current Status of Loans for Solar PV Installations Analysis and explanation of various bank loan rationale and methods for financing solar photovoltaic projects. Lenders lack the methods, data, and process for making loans for PV systems. Specific suggestions for improving the system for making bank loans are described. October 2006 Barbara Farhar A New Market Paradigm for Zero-Energy Homes: the San Diego Case Study In depth interviews of neighborhood homeowners, mailed surveys, actual sales data, and utility expenditures were analyzed over a four year period. Builders should offer PV as a standard feature to improve sales and satisfaction of homeowners as part of the study focused on the value of building zero energy homes, the study found that new home builders do recover their investment in PV because of the quicker sales and higher satisfaction by the PV home buyers as compared to non-pv home buyers Jan/Feb 2008 Barbara Farhar Advancing a Market for Zero-Energy Homes Additional analysis of Zero Energy Homes (ZEH) and mean gains in property values, more time and perspective since study was first published. PV homes had lower utility bills and higher resale prices than non PV homes, and were more satisfied than comparison buyers January 2008 Severin Borenstein The Market Value and Cost of Solar Photovoltaic Electricity Production. UC Berkeley: Center for the Study of Energy Markets Analysis of the time of useage and the distribution of energy of small , ie., 10kw PV systems compared to non-PV systems in 2000-2005. In 2000-2005 the cost of solar PV was higher than the non PV market wholesale cost of the power it produces, given these theoretical bases., July 2009 Andy Black, P.E. Economics of Solar Electric for Consumers: Payback and other Financial Tests Analyzes, explains and proposes and describes several methods for defining the financial value of PV and clarifies how the 1:20 valuation should be used in the marketplace Agrees with and promotes with conclusion from 1998 Nevin study. Uses the 1:20 valuation in describing real estate values of PV.
    • 15.  
    • 16. Solar Resale Value: McCabe/Merry
    • 17. Major findings (McCabe/Merry)
      • Solar saves between $500-1000 per year
      • Everyone thinks solar increased value, buyers more than sellers
      • No matter the system size, there is real value in solar
      • Faster selling cycle (anecdotal)
      • Initial results published in Journal of Sustainable Real Estate Aug 2010

      • Three minutes makes a difference.
      • If you sold, bought or own PV, we need your input.
