Solar Thermal Evaluation(ST10214)

Sundog Solar, Inc.


Flat plate collectors have been an industry standard for several decades. In the last decade, several manufacturers have begun offering evacuated tube collectors. These collectors frequently consist of a heat pipe attached to an absorber fin encapsulated in a glass tube. A vacuum is created when the glass tube is sealed to create a highly insulated barrier to minimize heat losses from the absorber plate. Flat plate and evacuated tube collectors have different operating characteristics that can affect what technology is more effective for a given application. To date, a side-by-side comparison of these collector types has not been conducted in New York.

Project Description

Sun Dog Solar (the Contractor) shall conduct a side-by-side evaluation of four collector arrays: two flat plate (different manufacturers), one evacuated tube, and a hybrid combination of flat plate and evacuated tubes. This evaluation shall be conducted at Kling Magnetic's industry/office building in Chatham, NY. The four collector arrays will feed a common storage tank. The heat produced by the solar collectors will be used for space heating. The results of this evaluation will be published one technical article, placed on the Contractor's Web page, and presented at home shows that the Contractor schedules to attend.


The project’s results will provide useful information to guide system designers’ selection of collector technologies. The solar thermal system installed at this facility will save more than $1,166 annually in propane expenses.
