  1. Solar Thermal Community Action

  2. Agenda

  3. Agenda

  4. Introduction & Solar Thermal BasicsCanSIA Community Action Manual • Content & Purpose • Available through CanSIA • Electronic Copies can be freely distributed; will be available at www.cansia.ca Introduction In Canada Resource Ownership Cost Installers & RFP Future

  5. Introduction & Solar Thermal BasicsUses of Solar Thermal Residential • DHW (Domestic Hot Water) • ISP (Indoor Swimming Pool) • OSP (Outdoor Swimming Pool) • VAH (Ventilation Air Heating) Commercial • CHW (Commercial Hot Water) • ISP • OSP • VAH • Water Purification • Crop Drying • Electricity Generation Introduction In Canada Resource Ownership Cost Installers & RFP Future

  6. Introduction & Solar Thermal Basics Introduction In Canada Resource Ownership Cost Installers & RFP Future

  7. Introduction & Solar Thermal BasicsA Typical Closed-Loop Glycol System • Separate manufacturer’s systems will vary • DHW is by far the best choice economically in Canada. Introduction In Canada Resource Ownership Cost Installers & RFP Future

  8. Agenda

  9. Solar Thermal In CanadaInstalled Capacity • Canada has a large installed capacity of Unglazed Flat-Plate collectors, for OSP heating • 2004: Canadian installed capacity was 75MWth of generation, compared to 10-14MW of PV Introduction In Canada Resource Ownership Cost Installers & RFP Future

  10. Solar Thermal In Canada Best choices economically for ST Systems Residential • DHW is the industry-accepted standard. • Most common is the Glazed Flat-Plate collector • These can be used both with water (drain-back) or with glycol (pressurized closed-loop) Glazed Flat-Plate Collector Introduction In Canada Resource Ownership Cost Installers & RFP Future

  11. Solar Thermal In Canada Best choices economically for ST Systems Commercial • There are two applications accepted as having the best economic returns: CHW, and VAH Unglazed Perforated Flat-Plate VAH System Introduction In Canada Resource Ownership Cost Installers & RFP Future

  12. Agenda

  13. Solar Resource Assessment Introduction In Canada Resource Ownership Cost Installers & RFP Future

  14. Solar Resource AssessmentSite Assessment: General to ST & PV • Number of Considerations consistent with assessing a potential PV site • Direction & Angle to Sun • Load Factor • Age of Roof • Potential Winter or Future Shadowing/Blocking • Geographic Solar Radiation Supply Introduction In Canada Resource Ownership Cost Installers & RFP Future

  15. Solar Resource AssessmentSite Assessment: Solar Thermal Specific • Structure’s plumbing and electrical state • Plumbing Installation may require a Plumbing Contractors Licence • Fairly relaxed regulations and requirements • Toronto: plumbing permits or certain structural permits are required for some commercial applications only Introduction In Canada Resource Ownership Cost Installers & RFP Future

  16. Agenda

  17. Community Power & Ownership StructureCommunity Power • Community Power: • A type of project ownership • residents of a community with a similar goal pool their investment into a single or multiple renewable energy generation projects. Introduction In Canada Resource Ownership Cost Installers & RFP Future

  18. Community Power & Ownership StructureOwnership Structure: Two Models Neighbourhood residents pool investment and resources to achieve cost savings INDIVIDUALS Community Bulk Purchase Organization Co-operative or Local Project Funding Mechanism Result is either a number of individual installations, or a single project funded by pooled investment Single, Remotely Sited Installation PROJECTS Introduction In Canada Resource Ownership Cost Installers & RFP Future

  19. Local residents fund a project for a community centre Used for heating water for showering, laundry and ISP Heat energy metered, payment made to co-operative (system owners) Community Power & Ownership StructureOwnership Structure: Co-operative Models Model 1 Solar Thermal System (installed on community center, owned by co-op) ENERGY Community Center PAYMENT Co-operative (Community Residents) Introduction In Canada Resource Ownership Cost Installers & RFP Future

  20. Remotely sited field used for district heating Each home is metered and payment is made to the co-operative Profits are returned to residents Community Power & Ownership StructureOwnership Structure: Co-operative Models Model 2 Solar Thermal Field (Sited remotely, owned by residents) PAYMENT ENERGY Community Residents (Co-operative Members) Drake Landing, AB. District Heating Community Introduction In Canada Resource Ownership Cost Installers & RFP Future

  21. Primary Purpose: operate under the StandardOffer Program Only oneorganizationattempting toform underthis model:SolarShare Community Power & Ownership StructureOwnership Structure: Co-operative Models Model 3 Solar Thermal Field (remotely sited, owned by co-op) Provincial Government (through Standard Offer Program) ENERGY Provincial Energy Grid ENERGY PAYMENT PAYMENT Co-operative (Community Residents) Other Energy Consumers Introduction In Canada Resource Ownership Cost Installers & RFP Future

  22. Agenda

  23. Cost of Solar Thermal SystemsThe Cost of an Individual 4.2kWth System Introduction In Canada Resource Ownership Cost Installers & RFP Future

  24. Cost of Solar Thermal SystemsThe Cost of 50 Identical Systems (210 kWth) Introduction In Canada Resource Ownership Cost Installers & RFP Future

  25. Cost of Solar Thermal SystemsThe Cost of a Remotely Sited 210kWth Field Introduction In Canada Resource Ownership Cost Installers & RFP Future

  26. Agenda

  27. Installers & the RFP/RFQ ProcessInstallers • List of CanSIArecognized installersand systemmanufacturers canbe found on the CanSIA website: www.cansia.ca/directory Introduction In Canada Resource Ownership Cost Installers & RFP Future

  28. Request for Proposal Request for a bid on a specific system Bids are legal offers Decision committee must select one Better price achieved from quantity discount Request for Quote Request for a bid for a specific application Bids are not legal offers Homeowners will select their own winning bid Greater flexibility to individual homeowners Installers & the RFP/RFQ ProcessRFP/RFQ Process Introduction In Canada Resource Ownership Cost Installers & RFP Future

  29. Agenda

  30. Conservation Generation The Future of Solar Thermal PolicyTwo Methods of Categorizing ST Introduction In Canada Resource Ownership Cost Installers & RFP Future

  31. The Future of Solar Thermal PolicyConservation v. Generation • “Solar Thermal reduces the demand for energy”… “Solar Thermal generates energy that directly replaces electricity” Introduction In Canada Resource Ownership Cost Installers & RFP Future

  32. Conservation-based policy is almost always a subsidy (percentage of capital cost) New federal program ecoENERGY takes this approach Still trying to determine whether this is the best strategy; how to administer; eligibility requirements Advantages Subsidies reduce the capital cost obligation. Capital cost Intensity is commonly a barrier to acceptance The Future of Solar Thermal PolicyThe Policy of Energy Conservation Disadvantages • Subsidies provide no lasting incentive to maintain the system in order to produce at peak capacity Introduction In Canada Resource Ownership Cost Installers & RFP Future

  33. Generation-based policy is typically a Power Production Incentive (PPI) Ontario Standard Offer Program takes this approach Currently the SOP incorporates wind, bio-mass, small hydro and solar PV, but does not include Solar Thermal The Future of Solar Thermal PolicyThe Policy of Energy Generation Disadvantages • There is no federally recognized metering • Continued cost of project operation, administration, etc. Advantages • There is an incentive to ensure peak energy production, and to extend project life as long as possible Introduction In Canada Resource Ownership Cost Installers & RFP Future

  34. Conclusion • Solar Thermal industry is growing rapidly in Canada • Need for a centralized information sharing network for communities • CanSIA is developing a number of tools for Solar Thermal project organizers • Keep posted on the NRCan website for Federal and Provincial funding updates, and the OPA’s website for changes to the SOP
