Solar Water Heating – Natural Gas Assisted or Stand Alone Solar?" (2011)

Submitted by Raquel Ponte Costa on June 20, 2015

This presentation was created by Paul Outram of Sun Earth Inc. It provides background information on solar thermal water heating technology, and finishes by making the case for the necessity of hybrid natural gas – solar thermal water heating systems. The presentation is illustrated with photos and graphs throughout.

Solar Power for Tomorrow's World (2011)

Submitted by Raquel Ponte Costa on June 20, 2015

This presentation was created by Ken May of Abengoa Solar, and was published by the American Council for an Energy-Efficient Economy (ACEEE). It explains the potential of solar thermal hot water heating to displace conventional electric use and create long term utility savings.

Program Handbook: California Solar Initiative - Thermal (2012)

Submitted by Raquel Ponte Costa on June 20, 2015

This is the updated program handbook for the Thermal Program of the California Solar Initiative. It is the first update since 2010, and features revised steps for various groups to participate in the program. Further information on solar thermal incentives can be found here. The application revisions apply primarily to single-family and multi-family residences. Also revised are the application steps for natural gas displacing systems and systems that replaced electric/propane systems.

Break-even Cost for Residential Solar Water Heating in the United States: Key Drivers and Sensitivities (2011)

Submitted by Raquel Ponte Costa on May 30, 2015

This technical report was written by the National Renewable Energy Laboratory (NREL). It examines the technology and economics that determine whether the cost of energy saved by a residential solar thermal hot water heating system will equal the cost of purchasing electricity or natural gas generated heat from the grid. This is known as the break-even cost.

Submitted by Raquel Ponte Costa on May 30, 2015

This case study was written by Adroit Solar, a solar energy company in California. It profiles a solar thermal installation at the Mission Heights Condominium complex which provides solar thermal water heating to 116 residential units in 3 buildings.

Analyzing the Design and Performance of a Retrofit Solar Thermal Combination DHW and Space Heating System (2010)

Submitted by Raquel Ponte Costa on April 7, 2015

This paper comes from James Dontie of Gustavus Adolphus College. It reports on an analysis of a solar thermal combination domestic hot water and space heating system which was retrofitted into a residence in Minnesota.

The analysis attempts to distinguish between improvements to the residence’s heating system that came through using a solar thermal system instead of a conventional system, as compared to efficiencies that were the result of simply installing new equipment.
