Current Trends
• Solar Water Heating• Rapid Increase of Imports• Evacuated Tube Collector Models Proliferating• General Consensus: 2009 Installations Flat or Slightly Lower
• Solar Swimming Pool Heating• 2009 Sales Flat to Slightly Lower• Over 35,000 system equivalents installed (@ 350 feet2/system)
• Solar Space Heating• “Combi-system” interest grows• Air heating collector-based system interest grows
• Solar Air Conditioning• Interest growing as an electricity consumption reduction measure
US Federal Government Support• US Department of Energy “Solar Heating and
Cooling Research & Development Program”•Program Manager Bob Hassett
•2009 Actual Budget $3.7 million for solar thermal
•2010 Budget Request $6.5 million for solar thermal
•2010 Budget Request for PV $170 million
•2010 Budget Request for Concentrating Solar Power
$50 million

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& instantaneous
• SRCC OG-300 Solar System Certification required
• 43 System Suppliers participating• Systems must provide at least 50% of
water heating load• www.energystar.gov
www.seia.org
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 measure
• Limited activity in solar thermal RECs trading• Australia program includes solar water heating
• “Measured” versus “Predicted” energy generation at issue
Solar Rating & Certification Corporation
• 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

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
www.seia.org
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
www.seia.orgNY 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”
Courtesy: Atlas Manufacturing
±Pros:•Significantly faster testing (hours versus days)
•24/7/365 capability (not weather dependant)
± Cons:•May yield different results than outdoor testing
•Significant capital expense
•Ongoing maintenance
•Electricity intensive

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
