A Solar Design Manual for Alaska: Solar Technologies (2010)

Submitted by Raquel Ponte Costa on April 7, 2015

This report was written by Alaska Sun, which is a coalition in Alaska dedicated to furthering the use of solar energy in their state. It comes from their publication “A Solar Design Manual for Alaska” and focuses on various technologies that are commonly used in solar thermal systems.

Flat plate collectors are described as one of the most common solar thermal technologies and the report sketches one out in a diagram. Heat transfer fluids, which make many solar thermal systems possible, are covered and have the characteristics of what makes a good heat transfer fluid listed.

Solar Hot Water in Alaska (2011)

Submitted by Raquel Ponte Costa on April 7, 2015

This presentation was written by Harvey Bowers of the Alaska Center for Appropriate Technology (ACAT). It provides information on solar thermal water heating in cold climates and uses a case study and examples from installations in Alaska to demonstrate how solar thermal can be effective in similar settings.

Solar thermal heating, as demonstrated by the residence in question, works best in climates like Alaska’s when utilizing passive design and closed loop systems, as keeping solar fraction high is challenging during the winter.
