Active, but not high volume…

• 73 commercial solar thermal projects in last 3
  years: Half in new construction
• Of 73, 13 were solar pool heating
• Averages 24 projects per year
• Currently only one project has applied for
  Energy Trust SWH incentive in 2012

                  “Our solar systems
                  also reduce operating
                  costs, helping us to
                  keep rents low.”

   incentive

•   $7,000+ estimated
    annual energy cost
    savings

•   6,825 estimated
    annual therm

  Reasons for Low Volume
• Very few commercial solar water heating firms
• Little or no active marketing by commercial solar
  water heating firms
• Loss of BETC tax credits
• Prices for SWH not decreasing (like PV), but
  actually increasing…
• Competing technology
• Lack of capital availability
  Reviving the market: opportunities
• 1.5% for Solar required for all new public
  buildings
• ETO Commercial Incentive increased: $8 per
  Therm saved
• Chinese SWH products very inexpensive in
  China – Can Oregon firms learn
  products/techniques key for lower cost?
• PVT Systems: Capitalizing on the T part
• Can we adjust standards/Codes safely to allow
  lower cost systems?
• Third party owned systems on the horizon?
Market Sector opportunities

• Focus on new construction; early design
• Commercial market sectors with large HW
  loads:
   • Lodging, hospitality
   • Residential facilities (retirement homes,
     multifamily)
   • Swimming Pools
   • Year round dormitories (education)
