Solar Thermal Heating (2009)

Submitted by Raquel Ponte Costa on June 21, 2015

This brochure was created by CareyGlass Solar. It explains how solar thermal water and air heating function, and the various technologies that make this possible.

The report details how solar thermal collectors are able to capture the heat of the sun and then pump that energy through a home’s air or water heating systems; there is a diagram to demonstrate this process. From here, the brochure explains how to properly fit and select collectors based on a home’s needs, and whether evacuated or flat plate is the proper collector type.

Efficiency of Evacuated Tubular Solar Thermal Collector (2011)

Submitted by Raquel Ponte Costa on June 21, 2015

This presentation was created and published by Junkun Ma and Xialu Wei of Southeastern Louisiana University. It provides an overview of how the measure the efficiency of evacuated tubular solar thermal collectors. In particular, the researchers set out how to best determine the efficiency of single ended evacuated tube collectors. Geometric modeling can be used for mounting angles and system analysis can be used for aspect ratios. The system analysis looks at heat transfer, fluid dynamics, volume force; which all are used as inputs in the efficiency function.

Solar Thermal Alternative Residential Heating Methods (2011)

Submitted by Raquel Ponte Costa on May 23, 2015

This report was written by the Kotzebue Electric Association (KEA), which helps provide electricity to the indigenous NANA Region of Kotzebue, Alaska. It reports on test efforts at installing solar thermal heating systems in a number of homes in Alaska that were in need of home heating assistance.

Gravity Solar System Installation Manual (2009)

Submitted by Raquel Ponte Costa on November 17, 2010

This manual was produced by the company FreeFuelForever to teach installers and user how to manage the Gravity Solar System. The system is made of evacuated tubes with the collector panels integrated with the storage tank. This is also commonly known as a direct system, which drains by gravity, i.e., system is unpressurized.

The document includes as sections, system layout and description, installation procedure, inspection check list, cautions.
It is a good example of manual for solar products.

Small-scale Solar Thermal Energy and Traditional Buildings (2008)

Submitted by Hans Craen on June 17, 2009

This 2008 guide from English Heritage (the UK Government's Adviser on the Historic Environment within England) looks into the small-scale generation of solar thermal energy. The emphasis of the document lies on the practicalities that need to be taken into account for the installation of the solar thermal collectors on a historic building. It lists the different aspects that have to be taken into consideration in the planning stage (i.e. orientation, shading, wildlife). The guide also sets out the different installation options.

University of Colorado Solar Decathlon – Solar Thermal Water Heating is a Success (2002)

Submitted by Hans Craen on June 2, 2009

This document from 2002 goes over innovative collector technology and strategy for solar thermal water heating systems. For colder climates, they describe how evacuated tubes are more effective than traditional flat plate collectors. It has a flow chart to describe how the system is schemed.
