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

Solar Thermal In Canada Installed Capacity :Solar Thermal In Canada Installed 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 Resource Ownership Cost Installers & RFP Future In Canada
Solar Thermal In Canada Best choices economically for ST Systems :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) Introduction Resource Ownership Cost Installers & RFP Future In Canada Glazed Flat-Plate Collector
Solar Thermal In Canada Best choices economically for ST Systems :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 Introduction Resource Ownership Cost Installers & RFP Future In Canada Unglazed Perforated Flat-Plate VAH System

Solar Resource Assessment :Solar Resource Assessment Introduction Resource Ownership Cost Installers & RFP Future In Canada
Solar Resource Assessment Site Assessment: General to ST & PV :Solar Resource Assessment Site 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 Resource Ownership Cost Installers & RFP Future In Canada
Solar Resource Assessment Site Assessment: Solar Thermal Specific :Solar Resource Assessment Site 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 Resource Ownership Cost Installers & RFP Future In Canada

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

Installers & the RFP/RFQ Process RFP/RFQ Process :Installers & the RFP/RFQ Process RFP/RFQ Process 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

The Future of Solar Thermal Policy Two Methods of Categorizing ST :The Future of Solar Thermal Policy Two Methods of Categorizing ST Conservation Generation Introduction Resource Ownership Cost Installers & RFP Future In Canada
The Future of Solar Thermal Policy Conservation v. Generation :The Future of Solar Thermal Policy Conservation v. Generation “Solar Thermal reduces the demand for energy”… “Solar Thermal generates energy that directly replaces electricity” Introduction Resource Ownership Cost Installers & RFP Future In Canada
The Future of Solar Thermal Policy The Policy of Energy Conservation :The Future of Solar Thermal Policy The Policy of Energy Conservation 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 Introduction Resource Ownership Cost Installers & RFP Future In Canada Disadvantages
Subsidies provide no lasting incentive to maintain the system in order to produce at peak capacity
The Future of Solar Thermal Policy The Policy of Energy Generation :The Future of Solar Thermal Policy The Policy of Energy Generation Introduction Resource Ownership Cost Installers & RFP Future In Canada 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 Advantages
There is an incentive to ensure peak energy production, and to extend project life as long as possible Disadvantages
There is no federally recognized metering
Continued cost of project operation, administration, etc.
Conclusion :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
