     Investment Tax Credit (ITC) for Solar Thermal

• Original legislation established ITC effective 1/1/06

• Extended to 2016 in 2008

•$2,000 ITC cap eliminated effective 1/1/09
   • Was 30% of system price with a maximum $2,000
   • Now 30% of system price with no maximum
   • Specifically references “solar water heating,” not space heating

•Products for which credit claimed must be certified by SRCC

•SEIA will address eligibility of space heating and commercial
swimming pools

Energy Star Labeling for Solar Water Heaters

         • High Efficiency Water Heater Program
           began 1/1/09
            • Includes solar, natural gas, heat pump&

         • 43 System Suppliers participating
         • Systems must provide at least 50% of
           water heating load
      Renewable Energy Credits (RECs)

• RECs usually assigned to renewable electricity generation
   • Reduction of electricity consumption by solar thermal
     indistinguishable from renewable electricity generation
   • Some in REC assignment for solar with natural gas
   • Lakeland Electric (FL) and Sterling Planet completed first larger scale
     solar thermal REC trade

• Growing interest in thermal as consumption reduction

• Limited activity in solar thermal RECs trading
   • Australia program includes solar water heating

• “Measured” versus “Predicted” energy generation at issue
      Solar Rating & Certification
• Non-profit Corporation established 1980
• Internationally recognized standards (ISO 9806-1, 2 & 3)
•~ 74 Participant Suppliers
• ~ 300 solar collectors certified (OG-100)
• ~ 900 solar systems certified (OG-300)

Future SRCC Solar Thermal Objectives
•Certification for space heating (Combi-systems)
•Certification for concentrating solar collectors
•Certification for cooling (air conditioning) systems
•Standards for performance monitoring

SRCC OG-100 (Collector) and OG-300 (System)

  What is Solar Thermal Product Certification?

1. Solar collector undergoes durability test
2. Solar collector undergoes thermal
   performance test
3. Solar system (using certified solar
   collector) undergoes design evaluation
4. Solar system is rated for performance in
   various geographic areas

          NY Solar Thermal Symposium
Solar Collector Durability Test

•   Pre-test inspection
•   Pre-exposure Pressure Test
•   Thirty-Day Exposure Test
•   Thermal Shock/Water Spray Test
•   Thermal Shock/Cold Fill Test
•   Post-exposure Pressure Test

     NY Solar Thermal Symposium
Outdoor Collector Performance Testing

                    ± Pros:
                    • Accuracy of performance prediction

                    ± Cons:
                    •Time consuming – time required for
                    test completion contingent on weather
                    conditions (7 to 50 days in FL)

                    •Annual testing period limited based on
                    climatic conditions (geographic location)

                    •More manual labor may be required
                    (daily positioning of test stands in FL)

        Indoor Performance Testing with “Solar Simulator”
                                            •Significantly faster testing (hours
                                            versus days)

                                            •24/7/365 capability (not weather

                                            ± Cons:
                                            •May yield different results than outdoor

                                            •Significant capital expense

                                            •Ongoing maintenance

        OG-300 Solar System Certification

– Design review
     • Manufacturer or supplier’s system design evaluation
     • Component review (including substitutions)
     • Overall operation (known best practices)
– Comprehensive Installation Manual required
– Owner’s Operation Manual required
– However: System selection must be appropriate for
  the climatic conditions and the application
     • Some systems not designed for cold climates
     • Excessive collector area may lead to overheating
