Solar thermal (direct heat from the sun)

 

Solar thermal energy harnesses the sun’s heat directly to heat water or space, or to heat quantities of water for the production of electricity.  For example:

• Flat-plate, low-temperature collectors can heat swimming pools;
• Hot water can be produced for direct use or for space heating through baseboards or radiant floors;
• Higher temperature collectors – typically arrays of concentrating collectors using mirrors or lenses – can be used for electric power production.  
• New "solar wall" technologies are coming into use, such as the Unglazed Transpired Collector which pre-heats air for ventilation.

The work of installing solar thermal hot water systems is primarily system sizing and specification to meet a customer’s heating needs, then designing systems including the collector, heat exchange system, storage and mounting systems.  A solar thermal installer must also understand building code considerations and be able to communicate effectively with customers – present and future.

 

Solar thermal installers are certified by the North American Board of Certified Energy Practitioners (NABCEP). According to NABCEP, solar thermal installers must be able to:

 

1. Work safely with hot water and pool heating components;
2. Identify systems and their components
3. Adapt a system design for a given location
4. Conduct a site assessment
5. Install solar collectors
6. Install water heater and storage tanks
7. Install piping, pipe insulation and connecting system piping
8. Install mechanical/ plumbing equipment and other components
9. Install electrical control systems
10. Install operation and identification tas and lebels
11. Check out systems
12. Maintain and troubleshoot.
